Invertases (INVs) and pectin methylesterases (PMEs) are essential enzymes coordinating
carbohydrate metabolism, stress responses, and sugar signaling. INVs catalyzes the …

The ability of a plant cell to expand is largely defined by the physical constraints imposed by
its cell wall. Accordingly, cell wall properties have to be regulated during development. The …

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 …

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 apical wall of growing pollen tubes must be strong enough to withstand the internal
turgor pressure, but plastic enough to allow the incorporation of new membrane and cell …

Pectin, one of the main components of plant cell wall, is secreted in a highly methylesterified
form and is demethylesterified in muro by pectin methylesterase (PME). The action of PME is …

Abstract In Southern China, rice-oil rotations occur on soils with high levels of cadmium (Cd)
and low levels of available boron (B). Boron can alleviate Cd toxicity, as it affects the plant …

Pectic polysaccharides are an essential component of the primary plant cell wall. They are
particularly prominent in pollen tubes, where they control the structure and yielding …

Plant cell walls, which consist mainly of polysaccharides (ie cellulose, hemicelluloses and
pectins), play an important role in defending plants against pathogens. Most …

Abstract Arabidopsis (Arabidopsis thaliana) QUARTET (QRT) genes are required for pollen
separation during normal floral development. In qrt mutants, the four products of …
