Effect of Methyl Jasmonate on Phytoalexins Biosynthesis and Induced Disease Resistance to Fusarium oxysporum f. sp. Vasinfectum in Cotton (Gossypium hirsutum L.)

Figure 2

Phytoalexins isolated from cotton leaves. The compounds can be classified into five phenolic groups as follows: (i) stilbenoids: piceatannol, pterostilbene, and trans-resveratrol; (ii) hydroxycinnamic acids: caffeoyl-D-glucose, cichoric acid, and ferulic acid; (iii) chlorogenic acids: 3-p-coumaroylquinic acid and chlorogenic acid; (iv) flavonoids: catechin and gossypetin; (v) terpenoid aldehyde: gossypol.
