Identification of <i>Cysteine synthase</i> (<i>Cys</i>) Gene Family in Tomato (<i>Solanum lycopersicum</i>) and Functional of <i>SlCys5</i> in Cold Stress Tolerance.

ABSTRACT: Sulfur is an intermediate element in plants. It plays an important role in the growth and development of plants. Plant roots absorb sulfate from their external environment and produce cysteine under the catalysis of cysteine synthase. Cysteine is a synthetic precursor of sulfur-containing metabolites and critical molecules including glutathione (GSH), methionine, vitamins, coenzymes, and antioxidants. It also plays a central role in plant stress resistance. In this study, we identified the Cys family genes in tomato and analyzed the expression of SlCys genes under cold stress. A bioinformatics analysis showed that the SlCys gene promoters were rich in cis-acting elements related to stress response. Transcriptome data analysis and qRT-PCR (real-time fluorescent q
