Glassy State in Plant Cuticles during Growth
Cuticles are thin extracellular layers that cover the aerial parts of all higher plants in areas lacking secondary growth. Their chemical and m orpho logical roles as protective barriers between the plant and its environment has been reported (Hol loway, 1982). Plant cuticles are heterogeneous in nature. They consist o f epiand intracuticular wax fractions and, mainly, cutin which is a highly...
متن کاملThe formation and function of plant cuticles.
The plant cuticle is an extracellular hydrophobic layer that covers the aerial epidermis of all land plants, providing protection against desiccation and external environmental stresses. The past decade has seen considerable progress in assembling models for the biosynthesis of its two major components, the polymer cutin and cuticular waxes. Most recently, two breakthroughs in the long-sought m...
متن کاملInfrared and Raman spectroscopic features of plant cuticles: a review
The cuticle is one of the most important plant barriers. It is an external and continuous lipid membrane that covers the surface of epidermal cells and whose main function is to prevent the massive loss of water. The spectroscopic characterization of the plant cuticle and its components (cutin, cutan, waxes, polysaccharides and phenolics) by infrared and Raman spectroscopies has provided signif...
متن کاملIsolation of Plant Cuticles With Zinc Chloride-hydrochloric Acid Solution.
rhe cuiticle of plants is a heterogenous memnbranie in which wax, pectin and cellulose in varying l)ro)ortions are contained in a cutin franmework. In the isolation of cuticular membranes from leaves or fruits the wax is nornially removed by extraction xvith ani organic solvent before detachment of the memnbranes from the underlying epidermal cells. Detachnmenit is achieve(d by the use of eithe...
متن کاملPlant cuticles shine: advances in wax biosynthesis and export.
The plant cuticle is an extracellular lipid structure deposited over the aerial surfaces of land plants, which seals the shoot and protects it from biotic and abiotic stresses. It is composed of cutin polymer matrix and waxes, produced and secreted by epidermal cells. The use of forward and reverse genetic approaches in Arabidopsis has led to the identification of enzymes involved in fatty acid...
