US geneticists from Penn State University have revealed that by inactivating a single gene known as MSH1 in a plant can reduce its “stress memory” and eventually make its descendants more flexible towards harsh climatic conditions. Geneticists used the small flowering plant rockcress, a relative of cabbage, and mustard in the Brassica family for their research. The technique used in the genetic modification is epigenetic, it includes the expression of existing genes rather than new genetic material from another plant. Researchers claimed the breakthrough could pave the way for advancements in plant genetic engineering without any dispute regarding the genetic modification
