Rachel Amir's lab focuses on improving the nutritional value of plants by increasing levels of essential amino acids, especially methionine, which is often limiting and reduces plant nutritional quality. Recently, a link has been shown between methionine, the precursor to S-adenosylmethionine, a contributor of plant methyl groups, and epigenetic changes that affect gene expression and growth. We have about 100 publications. Rachel is a full professor and the dean of the Faculty of Life Sciences at Tel Hai University.
