During cuticle deposition, a massive flux of lipids occurs from the sites of lipid synthesis in the plastid and the endoplasmic reticulum to the plant surface. Recent genetic studies in Arabidopsis have improved our understanding of fatty acid elongation and of the subsequent modification of the elongated products into primary alcohols, wax esters, secondary alcohols, and ketones, shedding light on the enzymes involved in these pathways. In contrast, the biosynthesis of alkanes is still poorly understood, as are the mechanisms of wax transport from the site of biosynthesis to the cuticle. Currently, nothing is known about wax trafficking from the endoplasmic reticulum to the plasma membrane, or about translocation through the cell wall to the cuticle. However, a first breakthrough toward an understanding of wax export recently came with the discovery of ATP binding cassette (ABC) transporters that are involved in releasing wax from the plasma membrane into the apoplast. An overview of our present knowledge of wax biosynthesis and transport and the regulation of these processes during cuticle assembly is presented, including the evidence for coordination of cutin polyester and wax production.}, keywords = {ABC, ABC transporters, ACYL-COA SYNTHETASE, ALKANES, ARABIDOPSIS, ARABIDOPSIS-THALIANA, CHAIN FATTY-ACID, COENZYME-A SYNTHETASE, DEEP-WATER RICE, ECERIFERUM CER MUTANTS, ENDOPLASMIC-RETICULUM, fatty acid elongation, LEAVES PISUM-SATIVUM, LIPID-TRANSFER PROTEIN, primary alcohols, regulation of wax biosynthesis, TRANSPORTER}, isbn = {1040-2519}, url = {://000256593200027}, author = {Samuels, L. and Kunst, L. and Jetter, R.} } @article {706, title = {Thermal activation of hydrocarbon C-H bonds by Cp*M(NO) complexes of molybdenum and tungsten}, journal = {Accounts of Chemical Research}, volume = {36}, number = {4}, year = {2003}, note = {ISI Document Delivery No.: 669GJTimes Cited: 54Cited Reference Count: 36}, month = {Apr}, pages = {223-233}, type = {Review}, abstract = {Gentle thermolysis of appropriate Cp*M(NO)(hydrocarbyl)(2) complexes (Cp* = eta(5)-C5Me5) of molybdenum and tungsten results in loss of hydrocarbon and the transient formation of 16-electron Cp*M(NO)-containing complexes such as Cp*M(NO)(alkylidene), Cp*M(NO)(eta(2)-benzyne), Cp*M(NO)(eta(2)-acetylene), and Cp*M(NO)(eta(2)-allene) (M = Mo, W). These intermediates effect the single, double, or triple activation of hydrocarbon C-H bonds intermolecularly, the first step of these activations being the reverse of the transformations by which they were generated.
