Expression-based and co-localization detection of arabinogalactan protein 6 and arabinogalactan protein 11 interactors in Arabidopsis pollen and pollen tubes [PDF]
, 2013 Arabinogalactan proteins (AGPs) are cell wall proteoglycans that have been shown to be important for pollen development. An Arabidopsis double null mutant for two pollen-specific AGPs (agp6 agp11) showed reduced pollen tube growth and compromised ...

Evolutionary development of the plant spore and pollen wall
, 2011 Background and aims: Many key innovations were required to enable plants to colonize terrestrial habitats successfully. One of these was the acquisition of a durable spore/pollen wall capable of withstanding the harsh desiccating and UV-B-rich ...

Acta Botanica Neerlandica, 1980 SUMMARY In the Lilium anther a peritapetal and tapetal membrane are made by the tapetal cells. During the young microspore stage the pro-orbicules receive a matrix of mainly carbohydrates similar to that of the sexine. The plasma-membrane of the tapetal cells forms membrane-like lamellae.

LRX Proteins play a crucial role in pollen grain and pollen tube cell wall development [PDF]
, 2017 Leucine-rich repeat extensins (LRXs) are chimeric proteins containing an N-terminal leucine-rich repeat (LRR) and a C-terminal extensin domain. LRXs are involved in cell wall formation in vegetative tissues and required for plant growth.
