|a Heat waves associated with climate change seriously threaten crop productivity. Crop seed yield depends on the success of reproduction. However, reproductive development is most vulnerable to heat stress conditions. Perception of heat and its conversion into cellular signals is a complex process. The basic helix loop helix (bHLH) transcription factor, Phytochrome Interacting Factor 4 (PIF4), plays a significant role in this process. However, studies on PIF4- mediated impacts on crop grain yield at a higher temperature are lacking. We investigated the overexpression of GmPIF4b in soybean to alleviate heat-induced damage and yield using a transgenic approach. Our results showed that under high-temperature conditions (38°C/28°C), overexpressing soybeans plants had higher chlorophyll a and b, and lower proline accumulation compared to WT. Further, overexpression of GmPIF4b improved pollen viability under heat stress and reduced heat-induced structural abnormalities in the male and female reproductive organs. Consequently, the transgenic plants produced higher pods and seeds per plant at high temperatures. Quantitative RT-PCR analysis showed that the overexpressing GmPIF4b soybeans had higher transcripts of heat shock factor, GmHSF-34, and heat-shock protein, GmHSP90A2. Collectively, our results suggest that GmPIF4b regulates multiple morpho-physiological traits for better yield under warmer climatic conditions
