), which catch insects by way of a slippery interior surface that is coated with epicuticular wax crystals (Riedel et al., 2007). Gregory Buda, Christiane Nawrath, and Lacey Samuels for generously providing microscopy images and Eric Fich, Laetitia Martin, and Dr. Iben Sørensen for helpful comments and discussion. Accordingly, cuticles from a broad range of species, and in various ecological and agricultural contexts, have been studied from the perspective of their role as the primary barrier to transpirational water loss. 23) Volume 23 Edition by Markus Riederer (Editor), Caroline Muller (Editor) ISBN-13: 978-1405132688 First, the mechanism of intracellular and extracellular transport of wax and cutin precursors remains unknown, although key ABC transporters required for their export across the plasma membrane have been identified (Pighin et al., 2004; Bird et al., 2007; Chen et al., 2011). Crossref Annual Plant Reviews Volume 23: Biology of the Plant Cuticle 1. and you may need to create a new Wiley Online Library account. Some Interactions of Mineral Nutrients and Organic Substances in Plant Nutrition. A systematic analysis of both cuticle composition and gene expression in Arabidopsis indicates that wax synthesis is induced by water deficit, sodium chloride, and abscisic acid (ABA) treatments (Kosma et al., 2009). The identification of the hydroxyl groups that are esterified by CD1 and other cutin synthases should indicate whether the regiospecificity of cutin polymerization is enzymatically controlled and whether specific cutin synthases catalyze the formation of linear or branched domains of the cutin polymer. Bibliographic record and links to related information available from the Library of Congress catalog. However, the ability to make such modifications rationally will require an understanding of the complexity of cuticle function at the molecular level, and far less progress has been made in this regard.

Given their additional association with cuticle biosynthesis, it appears that a common feature of members of this protein family is playing key roles in the biology of the plant epidermis and the determination of epidermal cell fate. Biology of the Plant Cuticle (Annual Plant Reviews, Vol. Annual Plant Reviews: Biology of the Plant Cuticle: Riederer, Markus, Muller, Caroline: Amazon.com.au: Books Moreover, in several cases, intracellular lipidic inclusions were observed in ABC transporter mutants, further supporting their direct involvement in cuticular lipid export (Pighin et al., 2004; Bird et al., 2007; Bessire et al., 2011). C. V. Mosby ... cuticle A film composed of wax and cutin that occurs on the external surface of plant stems and leaves and helps to prevent water loss. 1. In addition to the characterized components of cuticle biosynthesis that can be incorporated into a coherent model, as discussed above, several genes/proteins have been identified that are required for cuticle formation but that lack a clear associated biochemical function that would place them in a specific point in the pathways. Through successive addition of two carbons per cycle derived from malonyl-CoA, the ultimate products of this complex are VLCFAs. Plus, free two-day shipping for six months when you sign up for Amazon Prime for Students. Genes (blue text) are described in the review. The field concerned with the diffusive transport of lipophilic organic non-electrolytes across the plant cuticle has reached a state of maturity. Given the broad scope and space limitation, not every aspect of cuticle biosynthesis is covered in depth, and recent specialized reviews focusing on cuticle biomechanical properties (Domínguez et al., 2011), defensive functions (Reina-Pinto and Yephremov, 2009), and transport barrier properties (Burghardt and Riederer, 2006) may be of further interest. Biology of the plant cuticle. In addition to the network of transcription factors that regulate cuticle biosynthesis, regulatory mechanisms that do not involve direct transcriptional activation or repression by promoter binding have recently been discovered. Buy Biology of the Plant Cuticle (Annual Plant Reviews): 23 Volume 23 by Riederer, Markus, Muller, Caroline (ISBN: 9781405132688) from Amazon's Book Store. Annual Plant Reviews, Volume 23 A much clearer picture is now emerging of the fine structure of the plant cuticle and its surface, the composition of cuticular waxes and the biosynthetic pathways leading to them. The significance of waxes and cutin in pathogen resistance, therefore, is suggested in a general sense, but, as with cuticle permeability, little is known about the relative importance of specific molecular classes or their intermolecular associations and packing within the architecture of the cuticle. Despite the importance of cutin in plant-pathogen interactions, the first surface encountered by foliar pathogens is formed by epicuticular wax crystals and films. Although the specific sequence of all intracellular biosynthetic steps will require additional characterization of the substrate specificity of each enzyme, biochemical characterization of Arabidopsis bifunctional GPATs indicates that they have a strong preference for ω-hydroxylated acyl-CoA, suggesting that hydroxylation precedes the transfer to glycerol (Yang et al., 2012). Christopher E. Jeffree, Science Faculty Electron Microscope Facility, Edinburgh, UK. Biology of the plant cuticle. Wax composition can vary substantially with species, ontogeny, and environmental growth conditions (Jenks and Ashworth, 1999). in the alpine region of central Japan were not related to mechanical damage of cuticle and cuticle thickness An example of the chemical and structural heterogeneity of plant cuticles is … 3. Functional anatomy reveals secretory activity in papillose anthers of a buzz‐pollinated Solanum species (Cyphomandra clade – Solanaceae). Recently, two transcription factors, MYB106 and MYB16, were identified as regulators of cuticle biosynthesis that function in a similar manner to WIN1/SHN1 (Oshima et al., 2013). Ames, Iowa. Taken together, these results strongly indicate that BDG proteins are closely linked to cutin polymer formation, although their mode of action remains mysterious. Bar = 5 μm. It has also become clear that the physiological role of the cuticle extends well beyond its primary function as a transpiration barrier, playing important roles in processes ranging from development to interaction with microbes. Journal of South American Earth Sciences. (Image courtesy of Dr. Lacey Samuels.) In many invertebrates the dead, noncellular cuticle is secreted by the epidermis. These include a variety of soluble flavonoid pigments that are typically localized within the vacuoles of epidermal cells, phenolic compounds present in the polysaccharide cell wall, and lipophilic phenolic molecules that are covalently bound to cutin or associated with waxes (Pfündel et al., 2006). 2. MYB30 is induced during infection by bacterial pathogens, leading to the up-regulation of several genes of the FAE complex, and ectopic overexpression of MYB30 leads to an increased wax load (Raffaele et al., 2008). This second function of SHN transcription factors in regulating the polysaccharide cell wall is further suggested by experiments in which the overexpression of Arabidopsis SHN2 in rice resulted in a significant increase in the amount of cellulose and a concomitant decrease in lignin (Ambavaram et al., 2011). For example, overexpression of WXP1 from Medicago truncatula in alfalfa (Medicago sativa) induced wax production (Zhang et al., 2005). A waxy covering on the surface of stems and leaves that acts as an adaptation to prevent desiccation in terrestrial plants. In the context of plant ecophysiology, cuticular transpiration can … Another example of an “orphan” cuticle-associated protein resulted from analysis of the Arabidopsis bodyguard (bdg) mutant, which exhibits a microscopically disorganized cuticle with increased permeability but significantly increased levels of wax and cutin (Kurdyukov et al., 2006a). This phenomenon has been observed in a wax-deficient tomato mutant (Smirnova et al., 2013), a range of Arabidopsis mutants with abnormal cuticles (Yephremov et al., 1999; Wellesen et al., 2001; Kurdyukov et al., 2006a; Bird et al., 2007), and transgenic Arabidopsis plants overexpressing a secreted fungal cutinase (Sieber et al., 2000). The full text of this article hosted at iucr.org is unavailable due to technical difficulties. A new paradigm has recently been proposed for the diffusion of polar compounds and water across the cuticle. The first cutin synthase has been identified (Girard et al., 2012; Yeats et al., 2012b), but there are certainly additional cutin synthases, and whether they are closely related to CD1 or belong to distinct protein families remains to be discovered.
