Identification, characterization, and expression of Oryza sativa tryptophan decarboxylase genes associated with fluroxypyr-meptyl metabolism.

ABSTRACT: Tryptophan decarboxylase (TDC) belongs to a family of aromatic amino acid decarboxylases and catalyzes the conversion of tryptophan to tryptamine. It is the enzyme involved in the first step of melatonin (MT) biosynthesis and mediates several key functions in abiotic stress tolerance. In Oryza sativa under pesticide-induced stress, TDC function is unclear. Three TDC differentially expressed genes (DEGs) and six TDC-coding genes were found to be expressed in fluroxypyr-meptyl (FLUME)-treated rice transcriptome datasets, which allowed researchers to explore the properties and roles of rice TDC family genes under pesticide-induced stress. By applying sequence alignment and phylogenetic analysis, two subfamilies of the TDC gene family-DUF674 and AAT_I-were found in rice, Glycine max, Zea mays,
