Pollen–pistil interactions in divergent wide crosses lead to spatial and temporal pre-fertilization reproductive barrier in flax (Linum usitatissimum L.) [PDF]
Scientific ReportsLinseed, has been a source of natural fiber for textile industries since its domestication. However, despite being the potential source of trait reservoir, the use of Linum wild genetic resources for the improvement of economic traits are not exploited ...

Investigating morphological and biological reproductive traits in self-fertile and -infertile macadamia cultivars [PDF]
BMC Plant BiologySelf-fertility is a commercially valuable trait in crop species, enabling fruit set without reliance on pollinators or external pollinisers. In macadamia, most cultivars are self-infertile, though some can produce nuts with self-pollen.

Identification of pre-fertilization reproductive barriers and the underlying cytological mechanism in crosses among three petal-types of Jasminum sambac and their relevance to phylogenetic relationships. [PDF]
PLoS ONE, 2017 Crosses among single-, double- and multi-petal jasmine cultivars (Jasminum sambac Aiton) are unable to easily generate hybrids. To identify the reproductive barriers restricting hybrid set, dynamic changes in jasmine pollen viability and pistil ...

Penetration of the stigma and style elicits a novel transcriptome in pollen tubes, pointing to genes critical for growth in a pistil. [PDF]
PLoS Genetics, 2009 Pollen tubes extend through pistil tissues and are guided to ovules where they release sperm for fertilization. Although pollen tubes can germinate and elongate in a synthetic medium, their trajectory is random and their growth rates are slower compared ...

Agronomy, 2022 The cultivated almond displays a gametophytic self-incompatibility system, which avoids self-fertilization, and it is controlled by a multi-allelic locus (S-locus) containing two genes specifically expressed in pistil (S-RNase) and pollen (SFB).

Intraspecific crossability and compatibility within Solanum aethiopicum
Heliyon, 2021 Understanding hybridization barriers is relevant for germplasm conservation and utilization. The prezygotic barriers to hybridization include floral morphological differences like pistil and stamen length, pollen characteristics and pollen-pistil ...

Mechanisms of prezygotic post-pollination reproductive barriers in plants
Frontiers in Plant Science, 2023 Hybridisation between individuals of different species can lead to maladapted or inviable progeny due to genetic incompatibilities between diverging species.
