plant resistance genes [19], while the DREB subfamily proteins interact with the cis-acting DRE/C-repeat (DRE/CRT) element with a core motif of A/GCCGAC in promoters of stress-induced genes to regulate gene expression and also respond to plant hormones such as ethylene, ABA and so on [2...
Besides the C-C bond, these long-chained compounds with a general formula F(CF2)n-R include a carbon–fluorine (C-F) bond, which is one of the strongest covalent bonds in organic chemistry, with the dissociation energy of ∆H = 450 kJ/mol [5]. Abundant use of these chemicals in ...
