From: Ammonia borane positively regulates cold tolerance in Brassica napus via hydrogen sulfide signaling
AB control of cold tolerance might be associated with the alteration of endogenous H2S production. After treatments for 3 d, the corresponding photos were taken, and changes in the root growth (A) were recorded. Meanwhile, the contents of TBARS (B) and REC (C) were also analyzed, and the distribution of O2..− and H2O2 (D) was histochemically determined. The error bars represent the SD. The different letters indicate significantly different values (P < 0.05 according to Turkey’s multiple range test)
