Pectin is an abundant cell wall polysaccharide with essential roles in various biological
processes. The structural diversity of pectins, along with the numerous combinations of the …

Our general understanding of plant responses to sub-zero temperatures focuses on
mechanisms that mitigate stress to the plasma membrane. The plant cell wall receives …

Freezing triggers extracellular ice formation leading to cell dehydration and deformation
during a freeze–thaw cycle. Many plant species increase their freezing tolerance during …

Emerging evidence suggests that long noncoding RNAs (lncRNAs) are involved in
regulation of plant response to environmental stress. CBF/DREB1s are highly conserved …

Plants adapt to freezing stress through cold acclimation, which is induced by nonfreezing
low temperatures and accompanied by growth arrest. A later increase in temperature after …

Background and aims Rhamnogalacturonan-II (RG-II) is a domain of primary cell-wall pectin.
Pairs of RG-II domains are covalently cross-linked via borate diester bridges, necessary for …

The extent of freeze dehydration of mesophyll cells in response to extracellular ice varies
from supercooling to severe freezing cytorrhysis. The structural factors involved are poorly …

Background In plants, a large diversity of polysaccharides comprise the cell wall. Each major
type of plant cell wall polysaccharide, including cellulose, hemicellulose, and pectin, has …

The Arabidopsis sensitive-to-freezing8 (sfr8) mutant exhibits reduced cell wall (CW) fucose
levels and compromised freezing tolerance. To examine whether CW fucosylation also …

De-methyl esterification of homogalacturonan and subsequent cross-linking with Ca2+ is
hypothesized to enhance the freezing survival of cold acclimated plants by reducing the …
