Phosphorus (P) is a crucial macronutrient for plant growth, development, and reproduction. The effects of low P (LP) stress on leaf senescence and the role of PHR1 in LP‐induced leaf senescence are still unknown. Here, we report that PHR1 plays a crucial role in LP‐induced leaf senescence, showing delayed leaf senescence in phr1 mutant and accelerated leaf senescence in 35S:PHR1 transgenic Arabidopsis...
Selenium(Se) is a biological essential trace element that affects the growth and health of fish. The present study aimed to explore the dietary Se requirement of triploid rainbow trout using Se‐yeast supplement. The levels of Se added to the basal diet were 0(Se0), 0.1(Se0.1), 0.3(Se0.3), 0.5(Se0.5), 1.0(Se1.0), 4.0(Se4.0) and 16.0(Se16.0) mg Se/kg diet respectively. Results showed that the fish fed...
