Overexpression of Histone Increases Plant Transformation by Agrobacterium

Summary

Purdue University researchers have found that a particular histone H2A variant of Arabidopsis is involved in Agrobacterium T-DNA integration into the Arabidopsis genome. A plant carrying a mutation of this gene cannot integrate T-DNA; however, the wild-type allele can complement this mutation. In addition, overexpression of the histone H2A gene in wild-type Arabidopsis increases the efficiency of Agrobacterium mediated transformation. Because the histone H2A gene can reside on the incoming T-DNA and be expressed in the recipient cell, researchers speculate that this effect will improve transformation rates in recalcitrant plants.
