Prepare plaques with antibiotics Kan, Spm, Amp
06/25/2014
Grow the selected pieces from the GB collection in liquid medium (performed in laminar air flow cabinet).
06/26/2014
Culture in agar Petri dish. 2 plaques: Amp and Kan.
Minipreps with EZNA Plasmid DNA MiniKit I.
Expected digestions:
pP35s | GB0030 | NotI | Buffer: Orange | 2981, 1105 |
pT35s | GB0036 | NotI | Buffer: Orange | 2981, 304 |
pAtUbq10 | GB0223 | NotI | Buffer: Orange | 2981, 714 |
pTAtHSP18.2 | GB0035 | NotI | Buffer: Orange | 2981, 328 |
pTTctp | GB0081 | NotI | Buffer: Orange | 2981, 487 |
Electrophoresis analysis.
We got the expected bands in all cases.
07/01/2014
AtrΔ11 amplification by PCR with primers that contain extra nucleotides to introduce them in the sequence.
We made a PCR amplification using the AtrΔ11 gene as a template and the oligos: R +F
Reagents needed:
- 32.5 μL of H2O miliQ
- 10 μL HF buffer
- 2 μL dNTPs
- 2.5 μL Reverse primer
- 2.5 μL Forward primer
- 1 μL template (AtrΔ11 gene)
- 0.5 μL phusion (polimerase)
PCR parameters: The annealing temperature was 60°C and the extension temperature was 65°C.
Electrophoresis performed to check the PCR product, which was expected to be around 1 kb.
pUPD ligation of EaDAcT, HarFar and AtrΔ11
Reagents needed for the reaction of ligation:
- 1 μL pUPD
- 1 μL PCR product/gblock product
- 1.2 μL buffer 10x
- 1 μL BsmBI
- 1 μL T4 ligase
- 6.8 μL H2O miliQ
Vfinal= 12 μL
Termocycler parameters: The ligase temperature was 16°C and the BsmBI temperature was 37°C.
As a result, there are obtained three different pUPD plasmids containing the genes EaDAcT, HarFAR and AtrΔ11.
07/02/2014
E. coli transformation. This step is performed in a laminar air flow cabinet (LAF). We have used an electrocompetent E. coli strain (DH5α) and a sample from each product of ligation made in the previous step (three pUPD plasmids, each of them containing one of the three genes), so transformation is made three times.
Reagents needed:
- E. coli aliquot
- 1.5 μL of ligation in pUPD (for each gene: EaDAcT, HarFAR, AtrΔ11)
Each mix is introduced in a electroporation vial and electroporated at 1500 V, then 300 μL of SOC are added to each vial. All of them were incubated at 37°C for 1 hour.
After incubation, culture in Petri plates (always in a LAF).
2 cell-culture dishes per transformation (with Ampicillin), one with 50 μL and the other with the remaining volume.
Petri plates are incubated at 37°C for 16 h.
07/03/2014
Transformed colonies selection. The white ones are recultured in liquid medium. One colony of each transformation is picked and cultured in 3.5 mL LB and 7 μL Amp. This step is repeated three times:
- 3x 1 colony of EaDAcT in pUPD + LB + Amp
- 3x 1 colony of HarFAR in pUPD + LB + Amp
- 3x 1 colony of AtrΔ11 in pUPD + LB + Amp
All tubes are incubated at 37°C overnight in agitation.
07/04/2014
Digestions in silico using Vector NTI to check after minipreps if ligations are correct.
EaDAcT | NotI | 2981, 1167 |
RsaI | 1876, 1343, 532, 306, 91 | |
HarFAR | NotI | 2981, 1440 |
PvuII | 2564, 1394, 463 | |
AtrΔ11 | NotI | 2981, 1056 |
BanII | 2570, 803, 351, 314 |
Digestion reagents:
- 0.5 μL restriction enzyme
- 2.5 μL buffer
- 21 μL H20 (miliQ)
- 1 μL sample
Preparation of master mixes
- Master mix for NotI
- 5 μL NotI
- 25 μL Orange
- 210 μL H20
- Master mix for RsaI
- 1.5 μL RsaI
- 7.5 μL Tango
- 63 μL H20
- Master mix for PvuII
- 1.5 μL PvuII
- 7.5 μL Green
- 63 μL H20
- Master mix for BanII
- 1.5 μL BanII
- 7.5 μL Tango
- 63 μL H20
Perform electrophoresis to check if the size of the fragments from the digestions is correct.
Comments:
- We picked blue colonies instead of white by mistake. We need to pick colonies again but this time make sure we pick white colonies.
- For the repetition we must find another enzyme instead of BanII as we found out that it doesn't cut very well.
07/06/2014
We picked again 3 colonies for each construction, and we made sure that we picked the WHITE ones. We cultivated them in a "double check" (name invented by us) liquid medium. Those tubes contain:
- 3.5 mL LB
- 7 μL Amp
- 7 μL X-Gal
- 3.5 μL IPTG (turns the tube blue if the colonies picked were blue)
07/07/2014
We made minipreps of yesterday's culture. Thanks to our "double check" medium we found which colonies were well picked. Finally we had minipreps of tubes HarFAR 1, 2, 3; EaDAcT 3 and AtrΔ11 2, 3.
Once we had the minipreps, we perform the digestions to check which were correct and send them to sequencing. This time we selected RsaI instead of BanII. The in silico digestions were as follows.
EaDAcT | NotI | 2981, 1167 |
RsaI | 1876, 1343, 532, 306, 91 | |
HarFAR | NotI | 2981, 1440 |
PvuII | 2564, 1394, 463 | |
AtrΔ11 | NotI | 2981, 1056 |
RsaI | 1879, 1310, 467, 327, 54 |

We run the electrophoresis gel to check if this time we have done it correctly.
Everything was OK. We sent AtrΔ11 (3), HarFAR (3) and EaDAcT (3) to sequence.
07/08/2014
Now, while we wait for sequencing results, we go on as they were going to be correct in order to save time.
The next step is to build a transciptional unit (TU) with our sequences. A transcriptional unit is a structure composed by promoter, coding sequence (CDS) and terminator in an α or Ω vector.
Reagents needed for ligation:
- 1 μL promoter 75 ng/μL
- 1 μL terminator 75 ng/μL
- 1 μL CDS 75 ng/μL
- 1 μL vector α
- 1.2 μL ligase buffer 10x
- 1 μL T4
- 1 μL BsaI
- 4.2 μL H20
Total: 12 μL
Take into account that if we want to make binary constructions later (merge 2 TU in a same vector), we need to clone each TU in a different α vector.

Transformation of constructions in E. coli
We finally got the sequencing results from 07/07/2014.
- Mutation in AtrΔ11 -> We threw away the colonies and transformed cells. We picked again white colonies.
- HarFAR -> Sequencing correct
- EaDAcT -> Synonim mutation in 601 (A -> T). This is a gBlock!
We took vectors 2Ω1 (GB0487) and 2Ω2 (GB0488) parts from the GB colection.
- Worked in the LAF
- Cultivated in a Petri dish with Spm
- Let them grow for one day
Cultivate transformated cells in two Kan plaques (Kan matches vector α)
- 50 mL transformation in one plaque
- Rest of the culture in another (250 μL aprox)

07/11/2014
We made minipreps of yesterday's liquid culture. Thanks to our "double check" medium we found which colonies were well picked. Finally we had minipreps of tubes AtrΔ11 3 and 6; 2Ω1; 2Ω2; constructions P35s:HarFAR:TatHSP 1, 2, 3 and PAtUbq:EaDAcT:TatHSP 1, 2, 3.

Miniprep quantification:
Piece | Tube | Concentration (ng/μL) | Volume (μL) |
P35S:EaDAcT:T35S in 2Ω2 | 1 | 350.7 | 33 |
P35S:EaDAcT:T35S in 2Ω2 | 2 | 271.1 | 33 |

P35S:AtrΔ11:T35S + P35S:HarFAR:T35S in 2Ω1 | 3 | 108.24 | 75.20 |
As the digestions of the transcriptional unit (TU) of EaDAcT were incorrect, we repeated the process from the ligation step.
We transformed the same TU in a E. coli competent strain (DH5α). Then, the transformants were cultured in LB media and Spm and stored at 37°C overnight.
Finally, in order to obtain the FAO1 gene, we want to extract the Candida tropicalis genome, so we have picked a colony of C. tropicalis. To check the extraction protocol, we used a yeast previously tested, Saccharomyces cerevisiae. We have cultured C. tropicalis in YPD media and S. cerevisiae in YPDA media at 28 °C (5 mL).
07/23/2014
Candida genome extraction
Saccharomyces cerevisiae is used as a control in order to see if we followed the protocol correctly. We aren't really sure if this protocol is going to work in Candida.
Cultures measured at 600 nm:
- S. cerevisiae Abs = 1.07
- C. tropicalis Abs = 0.39
S. cerevisiae is recultured with new media (1:2) because the previous media was saturated. 2.25 mL of YPD media were mixed with 2.25 mL of S. cerevisiae culture. The mix has to grow at 28 °C until the exponential phase is reached.
The absorbance was measured again:
- S. cerevisiae Abs = 0.52
- C. tropicalis Abs = 0.40
Buffers needed for the genome extraction were prepared freshly.The genome of both strains of yeast were extracted following the protocol:
- Grow yeast in 2 or 5 mL YPD to exponential phase.
- Collect cells in 1.5 mL eppendorf-cup (centrifugation 20 s, 6000 rpm).
- Wash once with 1 mL sterile water.
- Resuspend cells in 200 μL protoplast-buffer (100 mM Tris-HCl, pH 7.5, 10 mM EDTA, 1000 units Zymolyase/mL, 10 μL beta-mercaptoethanol/mL; prepare freshly!). Incubate at 37°C for 1-2 h and finally resuspend by turning the cups.
- Add 200 μL of Lysis-Mix (0.2 M NaOH, 1% SDS) an mix carefully (Don't vortex!).
- Incubate at 65 °C for 20 min and cool inmediately on ice.
- Add 200 μL of 5 M KAc (pH 5.4) and mix carefully (Don't vortex!) and incubate 15 min on ice.
- Centrifuge (13,000 rpm, 3 min) and transfer supernatant in a fresh cup.
- Add 2 μL RNase A (10 mg/mL) and incubate at 37 °C for 30 min.
- Add 600 μL isopropanol and mix carefully (Don't vortex!). Incubate at room temperature for 5 min ad centrifuge (13,000 rpm, 30 s).
- Remove the supernatant and wash with 70% ethanol (10 min at room temperature).
- Centrifuge (13,000 rpm, 30 s) and remove the supernatant.
- Dry DNA pellet in a speed-vacuum (not longer than 3 min!) and resuspend in 50 μL TE-buffer.
- Store chromosomal DNA at 4 °C (Don't freeze!). Concentration and quality can be checked in an agarose gel (loading 1/10 of the volume).
Genomic quantification:
Organism | Concentration |
S. cerevisiae | 72.2 ng/μL |
C. tropicalis | 1397.1 ng/μL |
Electrophoresis made to check the extraction quality was correct.
We did not observe genomic from Candida because we used a very diluted sample. We will repeat the gel tomorrow.
We picked EaDAcT colonies.
07/24/2014
The genomic quality of both organisms (C. tropicalis and S. cerevisiae) was checked in an agarose gel again.
We got the Candida genome band, however, the Saccharomyces genome band was not present.
Additionally, minipreps of the liquid culture made yesterday were made and also recultured in solid agar plate.
Miniprep digestions are going to be done tomorrow.
07/25/2014
Digestions in silico made for checking yesterday's minipreps:
Pieces/TU | Restriction enzyme | Expected bands |

As the FAO1 PCR was not correct, we repeated the reaction. Below is a table showing the details:
Reagent | FAO1-PCR1 | FAO1-PCR2 |
C. tropicalis genome | 2.5 μL | 2.5 μL |
HF Buffer | 30 μL | 30 μL |
dNTPs | 10 μL | 10 μL |

We made a mistake preparing the FAO1-PCR1 adding the wrong template, so we do not expect the correct FAO11-PCR1 product.
EaDAcT Transcriptional Unit (TU) transformation
Using an electrocompetent E. coli strain (DH5α) and 1.5 ul ligation (P35s:EaDAcT:T35s in 2Ω2), the mix is electroporated at 1500 V. Then, 300 μL of SOC are added and stored at 37°C with agitation.

Agroinfiltration in Nicotiana benthamiana.
- Agrobacterium control culture and P35s:GFP:P19:Tnos (x2 forth true leaves)
- TU AtrΔ11+TU HarFAR and P35s:GFP:P19:Tnos (x2 forth true leaves)
- TU AtrΔ11+TU HarFAR and TU EaDAcT and P35s:GFP:P19:Tnos (x2 forth true leaves)
Agroinfiltration protocol consists of:
- Centrifuge the cultures 15 min 3000 rpm and discard supernatant.
- 5 mL of agroinfiltration solution per culture. 100 mL of agroinfiltration solution were composed of 10 mL MES 100mM (pH 5.6), 1 mL MgCl2 1M and 100 μL acetosyringone solution 200 mM (19.62 mg, DMSO 500 μL; prepare freshly). Mix it with the vortex. If the culture is still turbid, add a bit more of agroinfiltration sollution. Put it in the (rodillos) for two hours.
- Measure the OD. The optimum OD for agroinfiltration is 0.2. If it is too high adjust the concentration with more agroinfiltration solution.
- Mix the cultures, keeping all of them in the same proportions.
- Proceed to agroinfiltration.

PHEROMONE ANALYSIS
PONER ENLACE DE LA WIKI
To begin with samples were obtained from the agroinfiltrated plants after 5 days. We collected 9 samples:
- 2 leaves from P35s:GFP:P19:Tnos
- 2 leaves from TU AtrΔ11+TU HarFAR and P35s:GFP:P19:Tnos
- 2 leaves from TU AtrΔ11+TU HarFAR and TU EaDAcT and P35s:GFP:P19:Tnos
- 1 leaf from a wild type plant
Each sample was stored in a vial and kept in liquid nitrogen. Leaves were mashed using a mortar and liquid nitrogen until powder from each leaf is obtained and stored in a vial .Samples must be always kept in liquid nitrogen or in a -80°C freezer . Afterwards the leaf powder was weighted and introduced in a 10 mL screwcap headspace vial.
- 94,6 mg of P35s:GFP:P19:Tnos leaf (replica 1)
- 97,0 mg of TU AtrΔ11+TU HarFAR and P35s:GFP:P19:Tnos leaf (replica 2)
- 118,7 mg of TU AtrΔ11+TU HarFAR and TU EaDAcT and P35s:GFP:P19:Tnos leaf (replica 1)
- 100,0 mg of wild type leaf
Then 150 μL of EDTA 500mM and 1 mL of a saturated solution of CaCl2 (5,7M) were added to each vial.
EDTA 500mM preparation:
Stock of solid EDTA Di-Sodium 372,24 Mw and a final solution of 50 mL, 500mM. 372,24*0,5*0,05=9,306 g in 50 mL.

Analysis was performed overnight
08/13/2014
First results of the analysis were obtained. The analysis proved that our plant was successfuly producing the desired pheromones in high concentration. As expected z-11-hexadecen-1-ol and z-11-hexadecen-1-ol acetate were being produced and also unexpectedly the z-11-hexadecenal.
As shown in the figure, the leaf agroinfiltrated with TU AtrΔ11+TU HarFAR and P35s:GFP:P19:Tnos (represented in black) shows a successful production of (Z)-11-hexadecen-1-ol compared with the negative control that only has P35s:GFP:P19:Tnos (represented in blue) and shows no expression.
In this figure, expression of (z)-11-hexadecen-1-ol and (z)-11-hexadecen-1-ol acetate is proved. The expression in the leaf infiltrated with TU AtrΔ11+TU HarFAR and TU EaDAcT and P35s:GFP:P19:Tnos is represented in black, and the negative control with P35s:GFP:P19:Tnos is represented in blue.
In this figure, an unexprected peak present in the leaf infiltrated with TU AtrΔ11+TU HarFAR and P35s:GFP:P19:Tnos (black) can be observed. Comparing its spectrum with the one provided from the database seems to be (z)-11-hexadecena, a desired pheromone, which is being produced by the plant itself using an endogenous alcohol oxidase. Nevertheless as it is produced with a low yield, the FAO1 of C. tropicalis search is still in progress.
The rest of the samples were prepared for the GC-MS analysis.
The samples were weighted, introduced in the vial and added with EDTA and CaCl2.
- 94,0 mg of P35s:GFP:P19:Tnos leaf (replica 2)
- 102,4 mg of TU AtrΔ11+TU HarFAR and P35s:GFP:P19:Tnos leaf (replica 1)
- 92,0 mg of TU AtrΔ11+TU HarFAR and TU EaDAcT and P35s:GFP:P19:Tnos leaf(replica 2)
Results of the replicae analysis are shown below:
In this replica, the sample with the TU AtrΔ11+TU HarFAR and P35s:GFP:P19:Tnos construction shows a huge production of (z)-11-hexadecen-1-ol.
In this replica, the sample with the TU AtrΔ11+TU HarFAR and TU EaDAcT and P35s:GFP:P19:Tnos shows a higher abundance of (z)-11-hexadecen-1-ol and z-11-hexadecen-1-ol acetate.
In order to verify that the analysed compounds are the desired pheromones, we acquired standards for (z)-11-hexadecen-1-ol and (z)-11-hexadecen-1-ol acetate and (z)-11-hexadecenal, and indeed, the analysed compunds were the right ones.

We had problems to amplify the FAO1 gene, so in order to obtain it we performed a colony PCR. Using this method, it is possible to amplify a fragment directly from a colony rather than a DNA sample.
We made two different PCRs, one of them as a positive control and the other one to amplify our disered DNA fragment.
Colony PCR protocol (Taq Polimerase):
- 1 colony (C. tropicalis)
- 1.5 μL dNTPs
- 1 μL Forward Primer
- 1 μL Reverse Primer
- 1 μL Taq Polimerase
- 5 μL Buffer 10X
- 39.5 μL H2O miliQ
Primers used as a control: HSR1 + 480 and RTRv + 1149.
Primers used to amplify FAO1 gene: iGEMJUL07_FAO1_1F and iGEMJUL08_FAO1_1R.

Starting from an agar plate containing a Candida gene bank, we add 1 mL of LB medium and we mix it. Then, the mix was transferred into a tube. We stored in glycerine part of the culture and 200 μL were mixed with 5 mL of LB media and Amp (2:1000).
The tube containing the gene bank was grown at 28ºC for 1 hour. Then, we made minipreps.
The electrophoresis gel shows that the colony PCR failed, even the control did not work. Additionally, we test the BbsI restriction enzyme and we found that it does not cut well.

We didn't obtain PCR product. There is a band for the barnase, but it should be around 330 bp.
08/08/2014
We repeat yesterday's PCR with 2 degrees less in the annealing step.
Results obtained are the same of yesterday's. We should think about charging something else.
08/11/2014
The previous PCR was repeated changing the annealing temperature to 61º C.
We still do not get PCR product.
08/12/2014
We forgot to adjust the TA29:Barnase:Tnos from GB 1.0 to 5 ng/μL. Maybe that's why PCRs don't work. We repeated again with the appropiate temperatures (60º C for TA29 and 63º C for barnase), but it still doesn't work!
08/18/2014
We transformed in E. coli the iGEM Barnase part (BBa_1716211), placed in Plate 3, 11o.

We repeat yesterday's PCR with 2 degrees less in the annealing step.
Now there is a band for P35s but it should not be there.
08/11/2014
The previous PCR was repeated changing the annealing temperature to 61°C.
We still do not get PCR product.
08/12/2014
We repeated the PCR once more, this time setting the annealing temperatures at (59°C for T35s and 61°C for P35s).
08/19/2014
We are trying another PCR strategy to obtain the PCR product.
- PCR1: P35S template (as previously done)
