Cyclo(Pro-Tyr), also known as maculosin, is a phytotoxin produced by the fungus Altemaria alternata, and has been found to cause black necrotic lesions on the leaves of spotted knapweed. The mechanism underlying the phytotoxic action of cyclo(Pro-Tyr) may lie in its ability to inhibit ribulose-l,5-diphosphate carboxylase. ...

In vitro methods of chitin degradation by bacteria such as Bacillus laterosporus, Bacillus pabuli. Bacillus stearothermophiilus, Bacillus subtilis. Bacillus thuringiensis sub sp. play a specific role in secondary metabolite production with suitable culture medium (YNB, LBB, NB) (Soiuza et al. 2005). Although 0.3% colloidal chitin concentrations significantly enhanced the chitinase activity in Fusarium chlamydosporum (Mathivanan et al. 1998), the additional colloidal chitin at 0.5% induced the maximum chitinase production in Bacillus sp. NCTV2 (Wen et al. 2002), Altemaria alternata (Sharaf 2005), and Trichoderma hanianum (Sandhya et al. 2005).
