Depends. Plants turn out to be more and more like animals. NOT like people but like animalsPlants, we are learning, have internal means of remembering and keeping track of things: In a study published in Nature Communications, researchers from Nara Institute of Science and Technology have revealed that a family of proteins that control small heat shock genes enables plants to ‘remember’ how to deal with heat stress… “Heat stress is often repeating and changing,” says lead author of the study Nobutoshi Yamaguchi. “Once plants have undergone mild heat stress, they become tolerant and can adapt to further heat stress. This is referred to as heat stress ‘memory’ and has been reported to be correlated to epigenetic modifications.” Epigenetic modifications are inheritable changes in the way genes are expressed, and do not involve changes in the Read More ›
