Abstract Salinity is a serious challenge for agriculture production by limiting the arable land. Rice is a major staple food
crop but very sensitive to salt stress. In this study, we used Arabidopsis for the functional characterization of a rice F-box
gene LOC_Os04g48270 (OsPP12-A13) under salinity stress. OsPP12-A13 is a nuclear-localized protein that is strongly upregulated under salinity stress in rice and showed the highest expression in the stem, followed by roots and leaves. Two
types of transgenic lines for OsPP12-A13 were generated, including constitutive tissue over-expression using the
CaMV35S promoter and phloem specific over-expression using the pSUC2 promoter. Both types… More >
