Overexpression of NtPhyA gene improves tobacco cold resistance under low temperature stress

Overexpression of NtPhyA gene under low temperature stress improved the cold resistance of tobacco. The transcriptome analysis found that NtPhyA affected the biosynthesis of lysine, metabolism of ascorbic acid and aldehyde acid, metabolism of glutathione, inositol phosphate metabolism, glycolysis/gluconeogenesis, TCA cycle, plant hormone signal transduction, metabolism of secondary metabolites and other pathways. Overall design: 6 samples were analyzed, including 2 plant materials, each with three replicates.
