TL;DR: A phylogenetic series ranging from the minimally glycosylated basic RPRPs to the highly glycoslyated acidic AGPs is proposed, based on similarities between dicots and gymnosperm extensins, and their marked difference from graminaceous monocotextensins.

TL;DR: A cell wall proteoglycan with pectin and arabinoxylan covalently attached to an arabinogalactan protein is described, identifying a cross-linked matrix polysaccharide wall protein architecture with implications for wall structure, function, and synthesis.

TL;DR: It is concluded that self-assembling amphiphiles of lysine-rich RSH extensin form positively charged scaffolds in the cell plate that may template further orderly deposition of the new cross wall at cytokinesis.

TL;DR: The 50th birthday of extensin pectate was celebrated by as mentioned in this paper, who highlighted unique advances of each decade from the initial discovery of hydroxyproline (Hyp) in cell walls to the current definition of extENSins as selfassembling amphiphiles that generate scaffolding networks, and where acid-base interaction may template assembly of the pectic matrix.

TL;DR: Altering Rab11 activity by expressing either a constitutive active or a dominant negative variant of Rab11b in pollen resulted in reduced tube growth rate, meandering pollen tubes, and reduced male fertility.
