Heat stress responses in Oryza sativa and Oryza australiensis

Heat stress negatively impacts plant growth, reproduction, and productivity, posing a growing threat to crop yields under climate change. Understanding thermotolerance mechanisms is critical for developing resilient crops. Oryza australiensis, a wild rice species native to Australia, exhibits greater heat tolerance than the cultivated Oryza sativa, though the molecular basis remains unclear. Here, we investigated comparative heat stress responses and recovery in both species.
