Water Deficit Does Not Compromise the Resistance to Insect Herbivores in Plants Associated With Fungal Endophytes Able to Produce Bioactive Alkaloids. [PDF]
Plant Cell EnvironABSTRACT Plants growing in nature are exposed to multiple abiotic and biotic stressors that sometimes occur sequentially. We hypothesised that drought will not compromise the resistance levels to herbivores when plants are associated with Epichloë endophytes able to produce bioactive alkaloids. Lolium perenne plants without (nil) and with Epichloë LpTG‐

Understanding the role of active site residues in CotB2 catalysis using a cluster model
Beilstein Journal of Organic Chemistry, 2020 Terpene cyclases are responsible for the initial cyclization cascade in the multistep synthesis of a large number of terpenes. CotB2 is a diterpene cyclase from Streptomyces melanosporofaciens, which catalyzes the formation of cycloocta-9-en-7-ol, a ...
