Cover Story: Heat stress during the flowering stage in soybean impacts seed viability and vigor, leading to poor germination. Understanding the molecular mechanisms of heat stress tolerance in soybean is critical for developing resilient varieties for sustainable production. We investigated the roles of fatty acid biosynthesis and metabolism in soybean heat stress tolerance by studying mutations in fatty acid desaturase (FAD) genes. A significant positive correlation was observed between the expression levels of FAD3A, FAD3B, FAD3C, and FAD2-3 genes and the decline in seed germinability in heat-exposed plants. This suggests that the reduced seed content of polyunsaturated fats in soybean may help prevent germination losses due to heat stress.
