Perturbation of H3K27me3-Associated Epigenetic Processes Increases Agrobacterium-Mediated Transformation.

Agrobacterium-mediated transformation is a core technology for basic plant science and agricultural biotechnology. Improving transformation frequency is a major goal for plant transgenesis. We previously showed that T-DNA insertions in some histone genes decreased transformation susceptibility, whereas overexpression of several Arabidopsis H2A and H4 isoforms increased transformation.
