| dc.description.abstract | Plant-specific NAC transcription factors are known to play pivotal roles in responses
to biotic and abiotic stress conditions which continuously challenge agricultural
productivity worldwide. Multiple NAC target genes have been characterized
functionally. In our previous study, a novel gene from soybean, GmNAC012, was
identified as potential gene involved in drought stress responses. To further explore
functions of this gene in stress response, GmNAC012-overexpressing Arabidopsis at
vegetative stage was performed drought and salinity stresses on soil or agar plate,
and related physiological indices were also measured. Under salinity condition,
transgenic plants resulted in higher root growth, lower bleaching rate as well as
lower root reduction rate, suggesting prospective role in enhancing salinity
tolerance. However, there was no difference found between GmNAC012-
overexpression and WT plants in response to drought condition. These results
demonstrated that GmNAC012 could be considered as potential gene for genetic
engineering aimed at enhancing salinity stress tolerance in soybean as well as in
other important crops.
