CP25121Annual ryegrass modulates gene expression in cold environments to enhance synthesis of monounsaturated and saturated fatty acids


This study investigates the effects of low temperatures on fatty acid metabolism in diploid and tetraploid annual ryegrass. Through qRT-PCR analyses, it shows significant changes in fatty acid profiles and the expression of key genes (ACACAα, MACPT, DESAT5), highlighting genotype-specific responses. The findings provide insights into cold adaptation mechanisms and offer potential targets for breeding climate-resilient forage crops.
