Fig. 1From: Genome-wide analysis of polyamine biosynthesis genes in wheat reveals gene expression specificity and involvement of STRE and MYB-elements in regulating polyamines under droughtThe PAs synthesis pathway. The green colour is the PA compounds. The molecules encircled in blue lines represent the precursor or substrate for PAs biosynthesis by PA synthesizing enzymes (written in red). ACL5, thermospermine synthase; ADC, arginine decarboxylase; AIH, agmatine iminohydrolase; ODC, ornithine decarboxylase; NLP1, N-carbamoylputrescine amidohydrolase/Nitrlase like protein 1; SAMDC, S-adenosylmethionine decarboxylase; SPDS, spermidine synthase; SPMS, spermine synthaseBack to article page
