TL;DR: The results show the need to undertake large-scale analyses, using multidisciplinary approaches, to unravel the consequences of stress on the cell wall and identify the key components that could be targeted to improve biomass production under stress conditions.

TL;DR: This study used real-time RT-PCR to gain an overview of the expression of the entire PME family at eight silique developmental stages, in flower buds and in vegetative tissue in the Arabidopsis to highlight the high diversity of PME expression profiles.

TL;DR: Major changes in cell wall composition were observed with modifications in phenylalanine ammonia-lyase (PAL) and cinnamyl alcohol dehydrogenase (CAD) activities in both non- and cold-acclimated experiments.

TL;DR: A dual function for the homeodomain transcription factor BELLRINGER (BLR) in the establishment and maintenance of the phyllotactic pattern in Arabidopsis is reported, providing new insights into the role of pectin demethylesterification in organ initiation and cell elongation and identifying an important component of the regulation mechanism involved.

TL;DR: Data indicate a role for esterified pectins in cold tolerance, and the possible functions for pectin and their associated arabinans and galactans in cold acclimation are discussed.
