Plant cell walls are complex and dynamic structures that play important roles in growth and
development, as well as in response to stresses. Pectin is a major polysaccharide of cell …

Pectin methylesterase (PME) catalyses the demethoxylation of pectin, a major plant cell wall
polysaccharide. Through modification of the number and distribution of methyl-esters on the …

Pectin methylesterases catalyse the demethylesterification of cell wall polygalacturonans. In
dicot plants, these ubiquitous cell wall enzymes are involved in important developmental …

In bacteria, fungi and plants, pectin methylesterases are ubiquitous enzymes that modify the
degree of methylesterification of pectins, which are major components of plant cell walls …

Heat stress (HS) is expected to be of increasing worldwide concern in the near future,
especially with regard to crop yield and quality as a consequence of rising or varying …

Main conclusion Recent publications have increased our knowledge of how pectin
composition and the degree of homogalacturonan methylesterification impact the …

The pectin matrix of the cell wall, a complex and dynamic network, impacts on cell growth,
cell shape and signaling processes. A hallmark of pectin structure is the methylesterification …

The cell wall is a complex structure mainly composed by a cellulose–hemicellulose network
embedded in a cohesive pectin matrix. Pectin is synthesized in a highly methyl esterified …

The methylesterification status of cell wall homogalacturonans, mediated through the action
of pectin methylesterases (PMEs), influences the biophysical properties of plant cell walls …

Pectin methylesterase (PME) is the first enzyme acting on pectin, a major component of plant
cell wall. PME action produces pectin with different structural and functional properties …
