Gene, 1993
A cDNA library from dormant potato tubers was screened for extensin (Ext)-like cDNAs (PTEL). The cDNAs recovered were partially sequenced and could be divided into two classes. One class, containing the repeating amino acid (aa) motifs, SPPPPSPKYVYK and SPPPPSPSPPPPYYYK, constitutes the potato counterpart of the tomato Ext-encoding gene previously ...

Leucine-rich repeat extensin proteins regulate plant salt tolerance in Arabidopsis
Proceedings of the National Academy of Sciences of the United States of America, 2018Significance Plants have evolved cell-wall integrity signaling pathways to maintain cell-wall homeostasis in response to stress conditions, but the components involved in the perception and transduction of cell-wall signals are largely unknown.

Synthesis of the Highly Glycosylated Hydrophilic Motif of Extensins
Angewandte Chemie, 2014AbstractExtensin, the structural motif of plant extracellular matrix proteins, possesses a unique highly glycosylated, hydrophilic, and repeating Ser1Hyp4 pentapeptide unit, and has been proposed to include post‐translational hydroxylation at proline residue and subsequent oligo‐L‐arabinosylations at all of the resultant hydroxyprolines as well as ...

Extensin Peroxidase Ties the Knots in the Extensin Network
1989I have been interested in cell separation and primary cell walls since 1958 when I cut down a sycamore-maple tree in Madingley Wood, Cambridge U.K. and induced the cambial tissues to proliferate, first as a friable callus, and soon after as the first pipettable cell suspension culture to be used by a biochemist.

Multicellular organisms are composed of coordinately regulated cells embedded in a secreted extracellular matrix. This secreted cell wall integrates the biophysical structure of groups of cells to form tissues, and regulates the growth and development of the entrapped cells by a variety of mechanisms.

A gene for Brassica napus extensin is differentially expressed on wounding
Plant Molecular Biology, 1996We have analysed the expression of the endogenous extensin genes in Brassica napus, using northern hybridisation and dot blotting. In the unstressed plant, the extA gene is only expressed in the root, expression in the leaf, petiole and stem being absent. We have found that wounding dramatically alters this normal pattern of expression.

Analysis of Pectins, Extensins, and Hemicelluloses in Abscission Zones
Plant organ detachment occurs through the activation of specific, highly specialized cells, named the abscission zone (AZ). Molecular and biochemical transformations are induced in this specific tissue region that lead to the loosening of the cell walls, middle lamellae dissolution, and, as a consequence, the separation of the organ from the maternal ...Emilia, Wilmowicz +2 more

Identification of Extensin Protein Associated with Sugar Beet Pectin
Journal of Agricultural and Food Chemistry, 2009Several studies have suggested that the emulsification properties associated with pectin obtained from sugar beet (Beta vulgaris) are due to the presence of a protein-pectin complex. Nevertheless, the identity of the protein has remained elusive. Pectin, extracted from sugar beet pulp by microwave-assisted extraction, and a commercial sample were both ...

Spinach extensin exhibits characteristics of an adhesive polymer
Acta Botanica Neerlandica, 1993We have investigated the possibility that extensins (basic, hydroxyproline-rich glycoproteins of the primary cell wall) contribute to cellular adhesion. Soluble [ 14 C]extensin, obtained by salt-elution from the walls of living spinach (Spinacia oleracea L.) cells, was found to adhere strongly to all surfaces tested, including glass, polypropylene and ...
