Thermomorphogenesis and the heat shock(HS)response are distinct thermal responses in plants that are regulated by PHYTOCHROME-INTERACTING FACTOR 4(PIF4)and HEAT SHOCK FACTOR A1s(HSFA1s),*** is known about whether these responses are interconnected and whether they are activated by similar *** analysis of transcriptome dynamics in response to warm temperature(28℃)treatment revealed that 30 min of exposure activated the expression of a subset of HSFA1 target genes in Arabidopsis ***,a loss-of-function HSFA1 quadruple mutant(hsfa1-cq)was insensitive to warm temperature-induced hypocotyl *** hsfa1-cq plants grown at 28℃,the protein and transcript levels of PIF4 were greatly reduced,and the circadian rhythm of many thermomorphogenesis-related genes(including PIF4)was ***,the nuclear localization of HSFA1s and the binding of HSFA1d to the PIF4 promoter increased following warm temperature exposure,whereas PIF4 overexpression in hsfa1-cq partially rescued the altered warm temperature-induced hypocotyl growth of the *** together,these results suggest that HSFA1s are required for PIF4 accumulation at a warm temperature,and they establish a central role for HSFA1s in regulating both thermomorphogenesis and HS responses in Arabidopsis.

Asymmetric reductive amination directly converts ketones and amines to alkylamines, which are important motifs in *** report that cationic nickel complexes of chiral diphosphines promote enantioselective reductive amination of benzylic ketones with both arylamines and benzhydrazide. Isopropanol was used as a safe and cheap source of hydrogen instead of formic acid. The reaction can be readily applied to a concise synthesis of diarylethylamines, a class of neuroactive substances.
