Effect of Overexpression of JERFs on Intracellular K⁺/Na⁺ Balance in Transgenic Poplar (Populus alba × P. berolinensis) Under Salt Stress.

ABSTRACT: Salt stress is one of the main factors that affect both growth and development of plants. Maintaining K⁺/Na⁺ balance in the cytoplasm is important for metabolism as well as salt resistance in plants. In the present study, we monitored the growth (height and diameter) of transgenic Populus alba × P. berolinensis trees (ABJ01) carrying JERF36s gene (a tomato jasmonic/ethylene responsive factors gene) over 4 years, which showed faster growth and significant salt tolerance compared with non-transgenic poplar trees (9#). The expression of NHX1 and SOS1 genes that encode Na⁺/H⁺ antiporters in the vacuole and plasma membranes was measured in leaves under NaCl stress. Non-invasive micro-test techniques (NMT) were used t
