Homogalacturonan (HG) is the most abundant pectin subtype in plant cell walls. Although it
is a linear homopolymer, its modification states allow for complex molecular encoding. HG …

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 …

Species that propagate by sexual reproduction actively guard against the fertilization of an
egg by multiple sperm (polyspermy). Flowering plants rely on pollen tubes to transport their …

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

A rapidly increasing body of literature suggests that many biological processes are driven by
phase separation within polymer mixtures. Liquid-liquid phase separation can lead to the …

Studies investigating the mechanisms underlying the variation of photosynthesis along plant
phylogeny and especially during domestication are of great importance, and may provide …

Most organisms adjust their development according to the environmental conditions. For the
majority, this implies the sensing of alterations to cell walls caused by different cues. Despite …

In angiosperms, mature pollen is wrapped by a pollen wall, which is important for
maintaining pollen structure and function. Pollen walls provide protection from various …

Polarized exocytosis is critical for pollen tube growth, but its localization and function are still
under debate. The exocyst vesicle-tethering complex functions in polarized exocytosis …
