| Research Abstract |
We have demonstrated that Arabidopsis SR proteins, atSR45a and atSR30 participates in a spliceosomal assembly through other splicing factors and its expression is markedly induced by high-light stress. These facts suggest that atSR45a and atSR30 are involved in the regulation of high-light stress responsive-alternative splicing events. Here, we identified genes of which alternative splicing efficiencies are regulated by atSR45a and atSR30, by a whole genome tiling array technology, and demonstrated the involvement of the domains in atSR30 and atSR45a in subcellular and subnuclear distribution using a series of structural domain-deleted mutants.
