Biochemical Insights into Lipid Remodeling in Wheat Anthers Under High-Temperature Stress.

ABSTRACT: High-temperature (HT) stress during flowering significantly impairs anther development and pollen fertility, leading to substantial yield loss in wheat. A key aspect of plant adaptation to temperature stress concerns remodeling of lipid metabolism. In this study, heat-tolerant and heat-sensitive wheat cultivars were employed to investigate the biochemical alterations in lipid metabolism in response to high-temperature (HT) stress during anthesis. Pollen viability and SEM demonstrated that, under high temperature, the heat-tolerant cultivar maintained a more stable pollen structure and exhibited higher pollen fertility compared to the sensitive cultivar. Fatty acid analysis showed that HT led to a decrease in the unsaturated fatty acid 18:3 and an increase in the saturated fatty acid 16:0,
