“…(ixr1) and CESA6 (prc, ixr2) genes in most tissues is also compatible with the observations from genetic studies that these genes are involved in primary wall synthesis throughout the plants (also see below) (Arioli et al 1998;Fagard et al 2001;Scheible et al 2001). A CESA10::GUS promoter fusion indicates that CESA10 is expressed at the base of rosette leaves in Arabidopsis, which correlates with the very weak expression of the gene on the gene chips (Doblin et al 2002).…”

We have used Affymetrix gene chips to measure the expression of 10 CESA and 29 CSL genes of Arabidopsis in different developmental stages or organs. These measurements reveal that many of the genes exhibit different levels of expression in the various organs. While several CESA genes are highly expressed in all the tissues examined, very few CSL genes approach such high levels of expression. This suggests that the CSL genes either encode enzymes for the synthesis of minor components of cell walls or are expressed only in specific cell types. The expression data also highlights the potential importance of the CESA genes for primary and secondary cell wall formation during different developmental stages and in the different organs examined.Abbreviations: FTIR -Fourier transform infrared spectroscopy; CESA -cellulose synthase; cev 1 -constitutive expression of VSP1;

“…In longitudinally expanding cells, the cellulose microfibrils are deposited primarily in an orientation perpendicular to the axis of expansion, thus constricting radial expansion (Green, 1980;Taiz, 1984;Baskin, 2005). Consistent with this, disruption of cellulose biosynthesis by treatment with various chemical inhibitors results in a rapid loss of growth anisotropy (Scheible et al, 2001;Desprez et al, 2002).…”

Two Leucine-Rich Repeat Receptor Kinases Mediate Signaling, Linking Cell Wall Biosynthesis and ACC Synthase in Arabidopsis

et al. 2008

The plant cell wall is a dynamic structure that changes in response to developmental and environmental cues through poorly understood signaling pathways. We identified two Leu-rich repeat receptor-like kinases in Arabidopsis thaliana that play a role in regulating cell wall function. Mutations in these FEI1 and FEI2 genes (named for the Chinese word for fat) disrupt anisotropic expansion and the synthesis of cell wall polymers and act additively with inhibitors or mutations disrupting cellulose biosynthesis. While FEI1 is an active protein kinase, a kinase-inactive version of FEI1 was able to fully complement the fei1 fei2 mutant. The expansion defect in fei1 fei2 roots was suppressed by inhibition of 1-aminocyclopropane-1-carboxylic acid (ACC) synthase, an enzyme that converts Ado-Met to ACC in ethylene biosynthesis, but not by disruption of the ethylene response pathway. Furthermore, the FEI proteins interact directly with ACC synthase. These results suggest that the FEI proteins define a novel signaling pathway that regulates cell wall function, likely via an ACC-mediated signal.

“…In fact, orthologs of AtCesA1, AtCesA3, and AtCesA6 appear to be required for the synthesis of cellulose deposited in the primary cell walls (Fagard et al, 2000;Scheible et al, 2001;Burn et al, 2002;Doblin et al, 2002). In contrast, orthologs of AtCesA4, AtCesA7, and AtCesA8 seem to be essential for cellulose synthesis in the secondary cell walls (Turner and Somerville, 1997;Taylor et al, 1999Taylor et al, , 2000Taylor et al, , 2003Zhong et al, 2003).…”

“…Several models have been proposed to explain interactions among CESA isoforms, allowing proper formation of CelS (Scheible et al, 2001;Doblin et al, 2002;Joshi, 2003a). These models are based on the hypothesis that one elementary fibril is composed of 36 glucose chains, which are synthesized by 36 CESA isoforms arranged in a planar configuration in the plasma membrane (Delmer, 1999;Kimura et al, 1999;Scheible et al, 2001).…”

Annually, plants produce about 180 billion tons of cellulose making it the largest reservoir of organic carbon on Earth. Cellulose is a linear homopolymer of beta(1-4)-linked glucose residues. The coordinated synthesis of glucose chains is orchestrated by specific plasma membrane-bound cellulose synthase complexes (CelS). The CelS is postulated to be composed of approximately 36 cellulose synthase (CESA) subunits. The CelS synthesizes 36 glucose chains in close proximity before they are further organized into microfibrils that are further associated with other cell wall polymers. The 36 glucose chains in a microfibril are stabilized by intra- and inter-hydrogen bonding which confer great stability on microfibrils. Several elementary microfibrils come together to form macrofibrils. Many CESA isoforms appear to be involved in the cellulose biosynthetic process and at least three types of CESA isoforms appear to be necessary for the functional organization of CelS in higher plants.
