Yufei Zhao; Yigong Zhao; Yuxuan Peng; et al. Environmental and Experimental Botany 2024. doi:10.1016/j.envexpbot.2024.106037

Other claims from this paper (11)

Intervention effect Nitrogen application under elevated temperature did not significantly reduce leaf, panicle and canopy temperatures in rice.
Intervention effect Additional nitrogen under elevated temperature delayed the decline of chlorophyll in rice.
Intervention effect Additional nitrogen under elevated temperature maintained leaf photosynthesis in rice.
Intervention effect Additional nitrogen under elevated temperature prolonged the grain-filling period in rice.
Intervention effect Additional nitrogen under elevated temperature alleviated the warming-induced decrease of starch in rice.
Intervention effect Nitrogen application under elevated temperature improved antioxidant enzyme activity in rice.
Intervention effect Nitrogen under elevated temperature decreased H2O2 in rice leaves by 30.31% compared with elevated temperature alone.
Intervention effect Nitrogen under elevated temperature decreased H2O2 in rice grains by 45.33% compared with elevated temperature alone.
Intervention effect Elevated temperature promoted expression of heat-responsive genes, especially HSP16.9 and HSP26.7, consistently at 5-30 d after flowering in rice.
Intervention effect Nitrogen application under elevated temperature further increased expression of HSP16.9 (5 and 10 d after flowering) and HSP26.7 (10 d after flowering) in rice.
Mechanism The authors propose that HSP may be the key regulator of the grain response to warming with additional nitrogen.
