Physiological and molecular mechanisms of leaf response to high-temperature stress in high-temperature-resistant soybean varieties.

Background: With increasing global limate warm, high temperature (HT) is one of limiting factors for soybean yield and quality. Exploring HT resistance-related functional genes and their corresponding molecular mechanisms is of great value. In our previous report, compared with HD14 (HT sensitive), JD21 is an HT-resistant variety, and further analysis of the transcriptome and proteome has revealed the HT tolerance mechanism of JD21 anthers.

Integrated transcriptome and proteome analysis reveals molecular responses of soybean anther under high-temperature stress.

It is well documented that high temperature (HT) severely affects the development of soybean male reproductive organs. However, the molecular mechanism of thermo-tolerance in soybean remains unclear. To explore the candidate genes and regulatory mechanism of soybean response to HT stress and flower development, here, the anthers of two previously identified HT-tolerant (JD21) and HT-sensitive (HD14) varieties were analyzed by RNA-seq.
