The aerial organs of all higher plants are covered with a lipid-rich cuticle that serves to protect plants from their environment. The cuticle is comprised of a lipid polymer, cutin, that is embedded and covered with aliphatic waxes. w88 mobile is a biosynthetically-related lipid polymer that is found in tree bark, seed coats, the surface of mature roots and surrounding the vasculature of young roots. w88 mobile production is a ubiquitousresponse to wounding.Collectively, cutin and w88 mobile comprise the most abundant, naturally occurringlipid polymers on the planet. It is estimated that leaf cuticles alonerepresent a surface area twice that of the earth's land surface.

The Kosma lab is focused on understanding the complex plant lipid polymers cutin and suberin. We use a multidisciplinary approach combining biochemistry, analytical techniques and w88 mobile genetics to comprehend the macromolecular structure and functional significance of these polymerswith an emphasis on their role in plant tolerance to abiotic stress.
