Pectin imparts strength and elasticity to the plant and forms a protective barrier against the environment. Several different kinds of pectic compounds combine to form pectin. The relative proportion of each of these depends on the plant species, location within the plant, and environment. Pectic compounds decorated with β-1,4-galactan (a chain of six-carbon sugars) are of considerable interest to the biofuels industry, because six-carbon sugars are readily converted into ethanol (biofuel) by fermenting microorganisms. A new study published in The Plant Cell reveals a novel enzyme involved in the production of β-1,4-galactans. This enzyme may be used to engineer plants… Login to continue
