NADPH OXIDASE-DEPENDENT SUPEROXIDE PRODUCTION IN PLANT REPRODUCTIVE TISSUES [PDF]
In the life cycle of a flowering plant, the male gametophyte (pollen grain) produced in the anther reaches the stigmatic surface and initiates the pollen-pistil interaction, an important step in plant reproduction, which ultimately leads to the delivery ...

Proteomics Advances in the Understanding of Pollen–Pistil Interactions [PDF]
The first key point to the successful pollination and fertilization in plants is the pollen-pistil interaction, referring to the cellular and molecular levels, which mainly involve the haploid pollen and the diploid pistil.

Phylogenetic Relatedness Determines Heterospecific Pollen–Pistil Compatibility and Reproductive Outcome in the Apocarpous Species Sagittaria trifolia (Alismataceae) [PDF]
Pollinator sharing among coflowering plants can reduce plant fitness through heterospecific pollen (HP) deposition. Compatible HP is expected to cause stronger reproductive interference, but the factors determining HP–pistil compatibility and its ...

Pollen–pistil interactions in divergent wide crosses lead to spatial and temporal pre-fertilization reproductive barrier in flax (Linum usitatissimum L.) [PDF]
Linseed, 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 ...

Pollen–Pistil Interaction During Distant Hybridization in Plants
A combination of high potential productivity and ecological stability is essential for current cultivars, which is achievable by breeding. Interspecific/intergeneric hybridization remains a key approach to producing new high-yielding and resistant ...

The structure and allelic diversity of the self‐incompatibility locus (S‐locus) in diploid potatoes inferred from genome sequences and transcriptome data from styles and pollen [PDF]
Gametophytic self‐incompatibility (GSI) is a reproductive strategy to prevent inbreeding and promote outcrossing. Studies to understand molecular and evolutionary aspects of the self‐compatibility (SC)/self‐incompatibility (SI) system in the Solanaceae ...

Signaling at Physical Barriers during Pollen–Pistil Interactions [PDF]
In angiosperms, double fertilization requires pollen tubes to transport non-motile sperm to distant egg cells housed in a specialized female structure known as the pistil, mediating the ultimate fusion between male and female gametes. During this journey, the pollen tube encounters numerous physical barriers that must be mechanically circumvented ...

Penetration of the stigma and style elicits a novel transcriptome in pollen tubes, pointing to genes critical for growth in a pistil. [PDF]
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 ...
