Hydrogen Peroxide and GA₃ Levels Regulate the High Night Temperature Response in Pistils of Wheat (Triticum aestivum L.)

Antioxidants, 2023
High night temperature (HNT) impairs crop productivity through the reproductive failure of gametes (pollen and pistil). Though female gametophyte (pistil) is an equal partner in the seed-set, the knowledge of the antioxidant system(s) and hormonal ...

Natural Variation in Ovule Morphology Is Influenced by Multiple Tissues and Impacts Downstream Grain Development in Barley (Hordeum vulgare L.)

Frontiers in Plant Science, 2019
The ovule plays a critical role in cereal yield as it is the site of fertilization and the progenitor of the grain. The ovule primordium is generally comprised of three domains, the funiculus, chalaza, and nucellus, which give rise to distinct tissues ...

Keeping up with the RALFs: how these small peptides control pollen-pistil interactions in Arabidopsis.

New Phytologist, 2020
The pollen and pistil RALF peptides, along with multiple receptor-like kinases and leucine-rich repeat extensins, regulate pollen tube growth and the final burst within the ovule, where sperm cells are released for fertilization to occur.

The diversity of the pollen tube pathway in plants: towards an increasing control by the sporophyte

Frontiers in Plant Science, 2016
Plants, unlike animals, alternate multicellular diploid and haploid generations in their life cycle. While this is widespread all along the plant kingdom, the size and autonomy of the diploid sporophyte and the haploid gametophyte generations vary along ...

Mining for genes related to pistil abortion in Prunus sibirica L. [PDF]

PeerJ, 2022
In Prunus sibirica, the phenomenon of pistil abortion is very common and seriously affects its fruit quality and yield; however, the molecular mechanisms of pistil abortion remains unclear.

Two subgroups of receptor-like kinases promote early compatible pollen responses in the Arabidopsis thaliana pistil.

Journal of Experimental Botany, 2020
In flowering plants, cell-to-cell communication between the compatible pollen grain/growing pollen tube and the pistil is an essential component for successful sexual reproduction.

Determination of floral development stages in ‘Cabernet Sauvignon’ (Vitis vinifera L. cv.): highlighting the manifestation of stamens and pistil primordia with new intermediate stages linking the phenological stages [PDF]

Ciência e Técnica Vitivinícola, 2019
Despite relatively intensive work on the development of inflorescence primordia during grapevine growth in season one, some informational gaps are present in the flower and floral organ development in the season two.

Transcriptome and Network Analyses of Heterostyly in Turnera subulata Provide Mechanistic Insights: Are S-Loci a Red-Light for Pistil Elongation?

Plants, 2020
Heterostyly employs distinct hermaphroditic floral morphs to enforce outbreeding. Morphs differ structurally in stigma/anther positioning, promoting cross-pollination, and physiologically blocking self-fertilization.

POLLEN‐PISTIL RELATIONSHIPS IN THE POLEMONIACEAE [PDF]

Evolution, 1983
The multitude of floral architectures within angiosperms are complex adaptations (or adaptive strategies) insuring the transfer of pollen from a plant to another of the same species, the subsequent growth of the pollen tube in the style, and the fertilization of the ovule.
