Many plant, animal, and fungal genomes contain cytosine DNA methylation in asymmetric sequence contexts (CpHpH, H = A, T, C). Although the enzymes responsible for this methylation are unknown, it has ...
A Washington University study shows how plants use specialized enzymes, CMT2 and CMT3, to add methyl groups to DNA, regulating gene expression for environmental resilience. This discovery could inform ...
Xuehua Zhong (right), professor of biology at WashU, studies the evolutionary strategies that plants use to thrive and survive. She frequently studies Arabidopsis thaliana, or thale cress. Biologists ...
