TAMU -- Whether a plant withers unproductively or thrives in salty conditions may now be better understood by biologists.The cellular mechanism that controls salt tolerance has been found in the arabidopsis plant by a Texas AgriLife Research scientist collaborating with an international team. Complex-N-glycan, a carbohydrate linked to a protein in plant cells, was previously thought to have no helpful function for plant growth and to cause certain allergies in humans, according to Dr. Hisashi Koiwa, lead author of the study in this week’s Proceedings of the National Academy of Science.
