A Novel Role of Ring Chromosomes as Evolutionary Drivers of Herbicide Resistance
Plant Physiology, Plant Physiology: News and ViewsIn eukaryotes, chromosomes are linear structures; in contrast, a ring-shaped chromosome is a rare structure that results from the fusion of broken ends of linear chromosomes. Ring chromosomes may be induced by radiation or may occur spontaneously. In humans, ring chromosomes occur in approximately 1:50,000…
Sugar Coating the Phloem Sieve Element Wall
Blog, Plant Physiology, Plant Physiology: News and ViewsWhereas fluorescent tagging of proteins has dramatically advanced the study of protein function in cell biology, similar approaches with walls have been difficult due to the few methods available to visualize polysaccharides and monitor their dynamic modifications. What has become increasingly clear…
