Abstract
|
|
|
|
Swainsonine (SW) is the principal toxic ingredient of locoweed plants that causes locoism characterized by a disorder of the nervous system. It has also received widespread attention in the medical field for its beneficial anticancer and antitumor activities. Endophytic fungi, Alternaria sect. Undifilum oxytropis isolated from locoweeds, the plant pathogen Slafractonia leguminicola, and the insect pathogen Metarhizium anisopliae, produce swainsonine. Acquired SW by biofermentation has a certain foreground and research value. This paper mainly summarizes the local and foreign literature published thus far on the swainsonine biosynthesis pathway, and speculates on the possible regulatory enzymes involved in the synthesis pathway within these three fungi in order to provide a new reference for research on swainsonine biosynthesis by endophytic fungi.
