Fungicides
To eradicate fungal diseases
Project > Fungicides
The main objective of SubtiTree is to ensure the destruction of the pathogenic fungi inside the tree. In order to achieve this goal, we built a genetic module to produce three different peptides with antifungal activities.
Originated from plants, these peptides have different target to maximize the lethality on C. platani.
- D4E1 is a synthetic peptide made of 17 amino acids which has been shown to have an antifungal activity by complexing with a sterol present in the conidia’s wall of numerous fungi.
- GAFP-1 (Gastrodia Anti Fungal Protein 1) is a lectin binding to mannose thus inhibiting the growth of a variety of fungi.
- EcAMP-1 (Echinochloa crus-galli Anti Microbial Peptide) consists in 37 amino acids inhibiting hyphae elongation.
More information on this module :
EcAMP-1 was already present in the Registry, added by the Utah State 2013 iGEM team (BB_K1162001). We added D4E1 and GAFP-1 to the Registry of Standard Biological Parts (see parts). These new BioBricks were designed in order to be expressed and secreted with Bacillus subtilis.
Secretion :
The coding sequence of D4E1 and GAFP-1 was flanked on the N-terminal end with a signal peptide (amyE signal peptide) followed by a pro peptide, cleaved during the secretion process.
