Polymorphism and structure of style–specific arabinogalactan proteins as determinants of pollen tube growth in Nicotiana

BMC Evolutionary Biology, 2017
Background Pollen tube growth and fertilization are key processes in angiosperm sexual reproduction. The transmitting tract (TT) of Nicotiana tabacum controls pollen tube growth in part by secreting pistil extensin-like protein III (PELPIII ...

Reproductive assurance through autogamous self-pollination across diverse sexual and breeding systems [PDF]

, 2015
Pollination becomes a constraint when conspecific plants and/or their pollinators become scarce. Many plant species have evolved autogamous self-pollination as a means of reproductive assurance (RA) under pollination-uncertain environments. So far RA has

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]

, 2016
PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is

SLFL Genes Participate in the Ubiquitination and Degradation Reaction of S-RNase in Self-compatible Peach

Frontiers in Plant Science, 2018
It has been proved that the gametophytic self-incompatibility (GSI), mainly exists in Rosaceae and Solanaceae, is controlled by S genes, which are two tightly linked genes located at highly polymorphic S-locus: the S-RNase for pistil specificity and the ...

Transcriptome analysis reveals self-incompatibility in the tea plant (Camellia sinensis) might be under gametophytic control [PDF]

, 2016
BACKGROUND: Self-incompatibility (SI) is under genetic control and prevents inbreeding depression in angiosperms. SI mechanisms are quite complicated and still poorly understood in many plants.

Arabinogalactan proteins as interactors along the crosstalk between the pollen tube and the female tissues

Frontiers in Plant Science, 2016
Arabinogalactan Proteins (AGPs) have long been considered to be implicated in several steps of the reproductive process of flowering plants. Pollen tube growth along the pistil tissues requires a multiplicity of signalling pathways to be activated and ...

Current advances in genomics and breeding of leaf chicory (Cichorium intybus L.) [PDF]

, 2016
This review gives an overview of agricultural topics on a non-model species, in other words, leaf chicory. Often classified as a minor crop, \u201cRadicchio\u201d, the Italian name of leaf chicory, is assuming a very important role at both a local and ...

Differential expression patterns of Arabinogalactan Proteins in Arabidopsis thaliana reproductive tissues [PDF]

, 2014
36 p.-6 fig.Arabinogalactan proteins (AGPs) are heavily glycosylated proteins existing in all members of the plant kingdom and are differentially distributed through distinctive developmental stages.

Pollen–Pistil Interactions in Autochthonous Balkan Sweet Cherry Cultivars—The Impact of Genotype and Flowering Temperature

Agronomy
The efficacy of sweet cherry production is highly dependent on the regularity of flowering events and genetic-determined relations between female sporophyte and male gametophyte, which became even more important with higher flowering temperatures caused ...
