GmPHD5 was ubiquitously expressed and its expression was up-regulated by salinity stress in soybean. GmPHD5 was expressed in roots and leaves. Upper panel: western blotting results. Lower panel: SDS-PAGE gel image of the total proteins from soybean roots and leaves (A). GmPHD5 was upregulated by salinity stress in soybean. Upper panel: western blotting results. Lower panel: coomassie blue stained SDS-PAGE gels of soybean total proteins were showed as loading control (B).
