Comprehensive analysis of differentially expressed rice actin depolymerizing factor gene family and heterologous overexpression of OsADF3 confers Arabidopsis Thaliana drought tolerance.

ABSTRACT:

Background

Actin depolymerizing factors (ADFs) are small actin-binding proteins. Many higher-plant ADFs has been known to involve in plant growth, development and pathogen defense. However, in rice the temporal and spatial expression of OsADF gene family and their relationship with abiotic stresses tolerance is still unknown.

Results

Here we reported the first comprehensive gene expression profile analysis of OsADF gene family. The OsADF genes showed distinct and overlapping gene expression patterns at different growth stages, tissues and abiotic stresses. We also demonstrated that both OsADF1 and OsADF3 proteins were localized in the nucleus. OsADF1 and OsADF3 were preferentially expressed in vascular tissues. Under ABA or abiotic stress treatments, OsADF3::GUS activity was
