TL;DR: Transgenic maize plants transformed with the betA gene from Escherichia coli encoding choline dehydrogenase accumulated higher levels of glycine betaine and were more tolerant to drought stress than wild-type plants (non-transgenic) at germination and the young seedling stage.

TL;DR: The chilling tolerance, expressed in cell membrane damage, degree of chilling injury, survival rate, and photosynthesis was enhanced in plants of transgenic lines 2, 3, 4 and 5 as compared with wild type plants, which might play an important role of osmoregulation under stress conditions.

TL;DR: The lower membrane ion leakage and malondialdehyde level in these transgenic plants suggest that overexpression of H(+)-PPase causes the accumulation of Na(+) and Cl(-) in vacuoles instead of in the cytoplasm, thus reducing their toxic effects.

TL;DR: It is possible that both ZT and GA(3) were effective in protecting maize seedlings from water stress, which would be of great importance for the improvement of drought tolerance in maize by genetic manipulation.

TL;DR: The heterologous expression of TsVP in the yeast mutant ena1 suppressed Na(+) hypersensitivity and demonstrated the function ofTsVP as an H(+)-PPase, which supports the hypothesis that overexpression of H(-PPase causes the accumulation of Na(+ in vacuoles instead of in the cytoplasm and avoids the toxicity of excessive Na(-) in plant cells.
