Post-infection changes in lipids of the roots of a cotton plant variety moderately resistant to Verticillium dahliae

Post-infection changes in lipids of the roots of a cotton plant variety moderately resistant to Verticillium dahliae

Chemistry of natural compounds 25(1): 50-54

A comparative study has been made of the lipid composition of healthy roots of the cotton plant of the Tashkent-1 variety (I) and of the corresponding plants infected withVerticillium dahliae Kleb. (II) grown under field conditions. The action of the factors of infection stress and seasonal and climatic conditions change the lipid metabolism. In lipids (I) and (II) seven classes of neutral lipids (NLs), three classes of glycolipids, and six classes of phospholipids (PLs) were identified and their fatty acid compositions were determined. It was established that in (II) there was a smaller amount of total lipids, NLs, and PLs, and an increased level of polyphenolic pigments, but the level of gossypol pigments with free aldehyde groups was unchanged. In the NLs of (II), as compared with (I), there were more triacylglycerols, sterols, triterpenols, and squalene. Complex changes were observed in the fatty acid composition of the acyl-containing lipids.
