The role of gibberellin synthase gene VvGA2ox7 acts as a positive regulator to salt stress in Arabidopsis thaliana.

ABSTRACT:

Background

Soil salinity is an important environmental component affecting plant growth and yield, but high-salinity soils are a major constraint to the development of the grape industry. Previous studies have provided lines of evidence that gibberellins (GAs) play a significant regulatory role in plant responses to salt stress. However, it remains unclear whether GA2ox, a key enzyme that maintains the balance of bioactive gibberellins and intermediates in plants, is involved in the mechanism of salt stress tolerance in grapes.

Results

In this study, we found that GA2ox7 positively modulates salt stress via its ectopic expression in Arabidopsis thaliana. The GA2ox7 gene cloned from grape was a hydrophilic protein, its CDS length was 1002 bp. Besides, VvGA2ox7 protein contain
