Journal ArticleDOI
Solubilization and partial characterization of homogalacturonan-methyltransferase from microsomal membranes of suspension-cultured tobacco cells.
Florence Goubet,Debra Mohnen +1 more
TL;DR: The fragmentation of at least 55% to 70% of the radiolabeled product by endopolygalacturonase, and the loss of radioactivity from the product by treatment with pectin methylesterase, demonstrated that the bulk of the methylated product produced by the solubilized enzyme was pECTin.
Journal ArticleDOI
Oligosaccharins: Oligosaccharide Regulatory Molecules
Peter Albersheim,Alan G. Darvill,Christopher Augur,Jong-Joo Cheong,Stefan Eberhard,Michael G. Hahn,Victòria Marfà,Debra Mohnen,Malcolm A. O'Neill,Mark D. Spiro,William S. York +10 more
Journal ArticleDOI
A two-phase model for the non-processive biosynthesis of homogalacturonan polysaccharides by the GAUT1:GAUT7 complex
Robert A. Amos,Sivakumar Pattathil,Jeong-Yeh Yang,Melani A. Atmodjo,Breeanna R. Urbanowicz,Kelley W. Moremen,Debra Mohnen +6 more
TL;DR: A two-phase distributive elongation model is proposed in which a slow phase, which includes the de novo initiation of HG and elongation of short-chain acceptors, is distinguished from a phase of rapid elongations of intermediate- and long- chain acceptors.
Journal ArticleDOI
Downregulation of pectin biosynthesis gene GAUT4 leads to reduced ferulate and lignin-carbohydrate cross-linking in switchgrass.
Mi Li,Chang Geun Yoo,Yunqiao Pu,Yunqiao Pu,Ajaya K. Biswal,Ajaya K. Biswal,Allison K. Tolbert,Allison K. Tolbert,Debra Mohnen,Debra Mohnen,Arthur J. Ragauskas +10 more
TL;DR: The results reveal the roles of both decreased lignin-polymer and pectin cross-links in the reduction of recalcitrance in PvGAUT4-KD switchgrass, which has a lower abundance of ferulate and lign in-carbohydrate complex cross-linkages.
Journal ArticleDOI
Cell wall carbohydrates as signals in plants.
Debra Mohnen,Michael G. Hahn +1 more
TL;DR: The evidence that biologically-active oligosaccharides released from plant or microbial cell walls can serve as signals to regulate plant defense and plant growth and development is summarized.
