Descripción
Chitin is the second most abundant biopolymer in nature after cellulose and forms an integral part of insect exoskeletons, crustacean shells, krill, and the cell walls of fungal spores, where it is presentas a high molecular weight molecule. In this study, we showed that a chitin oligosaccharide of lower molecular weight (4mer) induced genes in Arabidopsis related principally to vegetative growth, development, and carbon and nitrogen metabolism. Based on 4mer plant response, a low molecular weight chitin mix enriched 92% by 2-4mers (CHL) was obtained with biotechnological purposes. CHL íncreased in vitre plant fresh weight (10%), radicle length (25%), and total carbon and nitrogen content (6% and 8%, respectively) compared with untreated plants. Our data shows that low molecular weight forms of chitin might play a role at nature as putative bio-stimulators of plant growth been also a known direct source of carbon and nitrogen of soil biomass. The biochemical properties of this mix might make it useful as non contaminant bio stimulant of plant growth and soil restorer on greenhouse and field in a future
