Homogalacturonan deesterification during pollen–ovule interaction in Larix decidua Mill.: an immunocytochemical study [PDF]
, 2014 Studies on angiosperm plants have shown that homogalacturonan present in the extracellular matrix of pistils plays an important role in the interaction with the male gametophyte. However, in gymnosperms, knowledge on the participation of HG in the pollen–

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 ...

Revisiting pollen-pistil interaction and cross incompatibility in maize
Current Research on Biosciences and Biotechnology, 2019 The review addressed aspects of plant fertilisation and the phenomenon of genetic cross-incompatibility in maize controlled by the Gametophyte1 locus. This phenomenon determines the failure to accomplish successful fertilisation and a full seed set when pollen grains carrying the ga1 allele pollinate female inflorescences carrying the Ga1-strong (Ga-1s)

Transcriptional Characteristics and Differences in Arabidopsis Stigmatic Papilla Cells Pre- and Post-Pollination [PDF]
, 2017 Pollination is an important early step in sexual plant reproduction. In Arabidopsis thaliana, sequential pollination events, from pollen adhesion onto the stigma surface to pollen tube germination and elongation, occur on the stigmatic papilla cells ...

Arbosana Olive Is Self-Incompatible, but Inter-Compatible with Some Other Low-Vigor Olive Cultivars
HorticulturaeTrendy high-density olive fields are often monovarietal orchards, mostly using the cultivar Arbequina. However, Arbequina shows a strong self-incompatibility response, and its yields depend on wind cross-pollination, which is not always available.
