Description
The Arabidopsis radial swelling mutant rsw10 showed ballooning of root trichoblasts, a lower than wild-type level of cellulose and altered levels of some monosaccharides in non-cellulosic polysaccharides. Map-based cloning showed that the mutated gene (At1g71100) encodes a ribose 5-phosphate isomerase (RPI) and that the rsw10 mutation replaces a conserved glutamic acid residue with lysine. Although RPI is intimately involved with many biochemical pathways, media supplementation experiments...[Show more]
