摘要

Salinity is one of the most critical environmental problems, which causes plant growth retardation by disturbing intracellular ion homeostasis. The Na+/H+ antiporter plays an important role in resistance to salt stress by sequestering Na+ in exchange for H+ across the vacuolar membranes. In the current study, the coding regions of two Arabidopsis antiporters (AtNHX1 and AtNHX2) and one rice antiporter (OsNHX1) were amplified by target specific PCR. PCR amplicons were first cloned into pENTR/D-TOPO and later recombined with a destination vector (pK7WG2.0) by LR reaction. Positive clones were selected by PCR, restriction digestion (RD) and sequencing. They were then transformed into Agrobacterium tumefaciens (LBA4404 strain) for subsequent transformation of farmer popular tomato varieties.
