Genomic Analysis of Soybean PP2A-B '' Family and Its Effects on Drought and Salt Tolerance.

ABSTRACT: Abiotic stresses induce the accumulation of reactive oxygen species (ROS) and significantly affect plant growth. Protein phosphatase 2A (PP2A) plays an important role in controlling intracellular and extracellular ROS signals. However, the interaction between PP2A, ROS, and stress tolerance remains largely unclear. In this study, we found that the B '' subunit of PP2A (PP2A-B '' ) can be significantly induced and was analyzed using drought- and salt-induced soybean transcriptome data. Eighty-three soybean PP2A-B '' genes were identified from the soybean genome via homologous sequence alignment, which was distributed across 20 soybean chromosomes. Among soybean PP2A-B '' family genes, 26 GmPP2A-B '' members were found to be responsive to drought and salt stresses
