The XTH family of enzymes involved in xyloglucan endotransglucosylation and endohydrolysis: current perspectives and a new unifying nomenclature.
The polysaccharide xyloglucan is thought to play an important structural role in the primary cell wall of dicotyledons. Accordingly, there is considerable interest in understanding the biochemical… Expand
A comprehensive expression analysis of all members of a gene family encoding cell-wall enzymes allowed us to predict cis-regulatory regions involved in cell-wall construction in specific organs of…
The Arabidopsis thaliana genome sequencing project has revealed that multigene families, such as those generated by genome duplications, are more abundant among plant genomes than among animal… Expand
Genomic basis for cell-wall diversity in plants. A comparative approach to gene families in rice and Arabidopsis.
Monocotyledons and dicotyledons are distinct, not only in their body plans and developmental patterns, but also in the structural features of their cell walls. The recent completion of the rice… Expand
The ANGUSTIFOLIA gene of Arabidopsis, a plant CtBP gene, regulates leaf‐cell expansion, the arrangement of cortical microtubules in leaf cells and expression of a gene involved in cell‐wall formation
We previously showed that the ANGUSTIFOLIA (AN) gene regulates the width of leaves of Arabidopsis thaliana, by controlling the polar elongation of leaf cells. In the present study, we found that the… Expand
A Surprising Diversity and Abundance of Xyloglucan Endotransglucosylase/Hydrolases in Rice. Classification and Expression Analysis1
A search of the recently completed genomic database of rice (Oryza sativa) identified a 29-member xyloglucan endotransglucosylase/hydrolase (OsXTH) gene family. This first report of a complete XTH… Expand

The plant cell wall plays a central role in morphogenesis as well as responsiveness to environmental signals. Xyloglucans are the principal component of the plant cell wall matrix and serve as… Expand
Demethylesterification of the Primary Wall by PECTIN METHYLESTERASE35 Provides Mechanical Support to the Arabidopsis Stem[W]
The ability of secondary cell walls to provide mechanical support to plant stems is well known. This work shows that primary cell walls also provide support. PECTIN METHYLESTERASE35 strengthens… Expand

Xyloglucan endotransglucosylases/hydrolases (XTHs) are a class of enzymes capable of catalyzing the molecular grafting between xyloglucans and/or the endotype hydrolysis of a xyloglucan molecule.… Expand
A Dof Transcription Factor, SCAP1, Is Essential for the Development of Functional Stomata in Arabidopsis
Stomata are highly specialized organs that consist of pairs of guard cells and regulate gas and water vapor exchange in plants [1-3]. Although early stages of guard cell differentiation have been… Expand
Active gene expression of a xyloglucan endotransglucosylase/hydrolase gene, XTH9, in inflorescence apices is related to cell elongation in Arabidopsis thaliana
Regulation of cell wall structure plays a central role in growth and differentiation in plants. Xyloglucan endotransglucosylase/hydrolases (XTHs) that catalyze the cleavage and molecular grafting of… Expand
