GID1 is the key regulatory gene in gibberellin signaling pathway, which mainly affects seed germination and plant growth. In this study, we cloned three homologous genes of GID1 in Zanthoxylum dissitum, namely ZaGID1a, ZaGID1b and ZaGID1c, by referring to its DNA library established by high throughput sequencing. Bioinformatics was applied to analyze nucleotide and putative amino acid sequences of homologous genes of GID1 in Z. dissitum, and the results indicate the encoded protein functional region, physiochemical property, phylogeny, hydropho...
