Two endogenous proteins that induce cell wall extension in plants.
TLDR
It is found that a crude protein extract from the cell walls of growing cucumber seedlings possessed the ability to induce the extension of isolated cell walls and these proteins appear to mediate "acid growth" responses of isolated walls and may catalyze plant cell wall extension by a novel biochemical mechanism. Expand
Sustainable liquid biofuels from biomass: the writing's on the walls.
TLDR
This review will focus on the underpinning research necessary to enable the cost-effective production of liquid fuels from plant biomass, with a particular focus on aspects related to plant cell walls and their bioconversion. Expand
Nomenclature for members of the expansin superfamily of genes and proteins
TLDR
Hans Kende*, Kent J.C.Voesenek, Yi Lee, Simon McQueen-Mason, Jocelyn K.C., and Laurentius A. Rose are the authors of this paper which aims to demonstrate the efforts towards in-situ applicability of E.J.D.’s law in the field of Plant Ecophysiology. Expand
Cell wall arabinan is essential for guard cell function
TLDR
This work shows that degradation of cell wall arabinan prevents either stomatal opening or closing, and suggests that arabinans maintain flexibility in the cell wall by preventing homogalacturonan polymers from forming tight associations. Expand
Molecular cloning and sequence analysis of expansins--a highly conserved, multigene family of proteins that mediate cell wall extension in plants.
TLDR
The high conservation of this multigene family indicates that the mechanism by which expansins promote wall extensin tolerates little variation in protein structure. Expand
Plant Expansins Are a Complex Multigene Family with an Ancient Evolutionary Origin1
TLDR
Based on phylogenetic analysis and shared intron patterns, a new, systematic nomenclature of Arabidopsis expansins is proposed, suggesting that the three plant expansin subfamilies arose and began diversifying very early in, if not before, colonization of land by plants. Expand
Lignocellulose degradation mechanisms across the Tree of Life
TLDR
The omics revolution is identifying many novel enzymes and paradigms for biomass deconstruction, but more emphasis on function is required, particularly for enzyme cocktails, in which LPMOs may play an important role. Expand
Arabidopsis genes IRREGULAR XYLEM (IRX15) and IRX15L encode DUF579-containing proteins that are essential for normal xylan deposition in the secondary cell wall.
TLDR
Immunostaining of xylan and transmission electron microscopy reveals that the walls of these irx15 irx15l double mutants are disorganized, compared with the wild type or other previously described xylan mutants, and exhibit dramatic increases in the quantity of sugar released in cell wall digestibility assays, which are consistent with irx 15 and irX15l defining a new class of genes involved in xylan biosynthesis. Expand
Expression of six expansin genes in relation to extension activity in developing strawberry fruit.
TLDR
The results demonstrate the presence of at least six expansin genes in strawberry fruit and that during ripening the fruit acquires the ability to cause extension in vitro, characteristic of expansin action. Expand
Disruption of hydrogen bonding between plant cell wall polymers by proteins that induce wall extension.
TLDR
It is reported that expansin proteins mechanically weaken pure cellulose paper in extension assays and stress relaxation assays, without detectable cellulase activity (exo- or endo- type). Expand
