GSH threshold requirement for NO-mediated expression of the Arabidopsis AtFer1 ferritin gene in response to iron.
FEBS Letters(2012)
摘要
Iron treatment of Arabidopsis cultured cells promotes a rapid NO burst within chloroplasts, necessary for up-regulation of the AtFer1 ferritin gene expression. The same occurs in Arabidopsis leaf chloroplasts, and is dependent upon the GSH content of plants. A leaf GSH concentration threshold between 10 and 50 nmol GSHg(-1) FW is required for full induction of AtFer1 gene expression in response to iron.
