Aug 21, 2002 · A new cellulose synthase gene (PtrCesA2) from aspen xylem is orthologous to Arabidopsis AtCesA7 (irx3) gene associated with secondary cell wall synthesis. Due to difficulties in isolation of active and intact cellulose synthase complexes from plants, identification of first candidate plant gene encoding catalytic subunit of cellulose
Biologia plantarum:Some aspects of cellulose biosynthesisCellulose synthases have been the subject of much research, and current conceptions and recent findings are reviewed in this paper. Severe effects of mutations and eion analysis have recently shown that chitinase-like proteins are crucial components of cellulose biosynthesis. However, understanding of their precise function is missed.
CESA3 - Cellulose synthase A catalytic subunit 3 [UDP Catalytic subunit of cellulose synthase terminal complexes ('rosettes'), required for beta-1,4-glucan microfibril crystallization, a major mechanism of the cell wall formation. Involved in the primary cell wall formation, especially in roots.
Sep 15, 2010 · We report the identification of a new allele of the Arabidopsis CesA7 cellulose synthase locus designated AtCesA7 irx35 involved in the control of TE. Leaves of the AtCesA7 irx35 mutant are warmer than the wild type (WT). This is due to reduced stomatal pore widths brought about by guard cells that are significantly smaller than the WT.
Cellulose Synthase Mutants Distinctively Affect Cell the WT (Ler; Fig. 1F). Moreover, the IRX3 mutant showed an insignicant change of cell lengths in the D9 hypocotyls (Fig. 1G) and of cell number in L9 RAM (Fig. 1H) compared with the WT, supporting the nding that AtCesA7 is one es-sential isoform of cellulose synthase complexes specic for SCW

CesA genes are believed to encode the catalytic subunit of cellulose synthase. Identification of nine distinctCesA cDNAs from maize (Zea mays) has allowed us to
Control of Cellulose Synthase Complex Localization in structure, the cellulose synthase rosette is likely to contain 18 to 36 CesA proteins (Delmer and Amor, 1995; Ha et al., 1998). At least three CesA genes are required for cellulose synthesis in the secondary cell walls of developing xylem vessels:IRX3 (AtCesA7) (Taylor et
Eion of a Mutant Form of Cellulose Synthase AtCesA7 Cellulose synthase catalytic subunits (CesAs) have been implicated in catalyzing the biosynthesis of cellulose, the major component of plant cell walls. Interac
Identification of genes required for cellulose synthesis by regression analysis of public microarray data sets Staffan Persson, Hairong Wei, Jennifer Milne, Grier P. Page, and Christopher R. Somerville§¶ Department of Plant Biology, Carnegie Institution, Stanford, CA 94305; Department of Biostatistics, University of Alabama at Birmingham,
Interactions among three distinct CesA proteins is caused by a decrease in cellulose content in secondary cell walls (8). irx1 and irx3 affect exactly the same cell types and are caused by mutations in the AtCes8 and AtCesA7 genes, respec-tively. Furthermore, coprecipitation experiments with an epitope-tagged version of IRX3 demonstrate that IRX3 and IRX1 function within the same enzyme
Structure of cellulose-deficient secondary cell walls from In the Arabidopsis mutant irx3, truncation of the AtCesA7 gene encoding a xylem-specific cellulose synthase results in reduced cellulose synthesis in the affected xylem cells and collapse of mature xylem vessels. Here we describe spectroscopic experiments to determine whether any cellulose, normal o
