Studies of the biosynthesis of tentoxin by Alternaria alternata [PDF]
Microbiology, 1994 Biosynthesis of the phytotoxin, tentoxin, its regulation and the enzymic synthesis steps were studied in vivo and in vitro. The physiology of biosynthesis of tentoxin in vivo was investigated by using sections of mycelial mats incubated in buffer. Differentiated mycelia could be studied under defined conditions.
