Comparative Transcriptomics Analysis and Functional Study Reveal Important Role of High-Temperature Stress Response Gene GmHSFA2 During Flower Bud Development of CMS-Based F₁ in Soybean.

ABSTRACT: High-temperature (HT) is one of the most important environmental factors that negatively impact the yield of some soybean cytoplasmic male sterility (CMS)-based hybrid (F₁) combinations. The response of soybean to HT, especially at the male organ development stage, is poorly understood. To investigate the molecular mechanisms of the response from soybean CMS-based F₁ male organ to HT, a detailed transcriptomics analysis was performed during flower bud development of soybean HT-tolerant and HT-sensitive CMS-based F₁ combinations (NF₁ and YF₁) under normal-temperature and HT conditions. Obvious HT damage was observed by subjecting YF₁ with HT, such as indehiscent anthers and decreased pollen fertility, whereas the male fertili
