Description
A
1-
Phytoprostane-
I is a cyclopentenone isoprostane produced by the action of reactive oxygen species on α-
linolenic acid in plants. There are two A
1-
phytoprostanes, both having the single ketone group on the ring structure. This isoform results from cyclization between carbons 9 and 13 of linolenic acid, as opposed to carbons 3 and 7 in A
1-
phytoprostane-
II. A
1-
Phytoprostanes induce the expression of glutathione-
S-
transferase, increase phytoalexin biosynthesis, and trigger the expression of several genes involved in primary and secondary metabolism in plants.
