Expression profiling of wild-type and XVE:PP2CABA-dHA rice roots

PP2CABA is an abscisic acid-inducible clade F2 protein phosphatase that regulates rice root development, lignin and suberin deposition, and adaptation to drought and flooding stress. We used Affymetrix Rice GeneChip microarrays to compare transcriptomic profiles between wild-type rice roots and roots of XVE:PP2CABA-dHA transgenic rice seedlings following β-estradiol induction.

This analysis was performed to identify genes and pathways regulated by PP2CABA in rice roots, particularly those associated with cell wall modification, phenylpropanoid biosynthesis, fatty acid elongation, and lipid transfer.
