From recognition to response: integrated signaling pathways determining pollen acceptance and rejection in Brassicaceae

New Phytologist, Volume 250, Issue 2, Page 788-798, April 2026.
Summary Generation of competent offspring is vital for the prosperity of flowering plants. The pistil not only functions as a conduit for pollen tubes to grow to the ovary but also provides a selective venue for facilitating the growth of compatible pollen tubes and discouraging invaders and incompatible pollen.

Molecular Approaches to Overcome Self-Incompatibility in Diploid Potatoes

Plants, 2022
There has been an increased interest in true potato seeds (TPS) as planting material because of their advantages over seed tubers. TPS produced from a tetraploid heterozygous bi-parental population produces non-uniform segregating progenies, which have ...

Several plant self‐incompatibility systems may be controlled by atypical receptor–ligand interactions

The Plant Journal, Volume 126, Issue 1, April 2026.
SUMMARY Self‐incompatibility (SI) is the single most important mechanism utilized by flowering plants to avoid self‐fertilization, thus preventing inbreeding and promoting outcrossing. Many plant SI systems are genetically controlled by a multi‐allelic S‐locus, containing two tightly linked genes that encode the female and male S‐determinants.

Identification of a Novel SBP1-Containing SCFSFB Complex in Wild Dwarf Almond (Prunus tenella)

Frontiers in Genetics, 2019
S-RNase-based gametophytic self-incompatibility (SI), in which specificities of pistil and pollen are determined by S-RNase and the S locus F-box protein, respectively, has been discovered in the Solanaceae, Plantaginaceae, and Rosaceae families, but ...

Transposable element‐mediated DNA methylation of the NAC20 and NAC26 promoters led to a maternal effect on grain filling

Journal of Integrative Plant Biology, Volume 68, Issue 3, Page 828-840, March 2026.
The rice transcription factor genes NAC20 and NAC26 regulate grain filling and show allele‐specific maternal expression due to transposable element insertions and paternal hypermethylation in their 5' upstream regions. Geographical analyses showed that japonica varieties that originated at high latitudes carried these transposable elements.

Inheritance of S-genotypes in Paviot × Kabaasi apricot F1 progenies

Biotechnology & Biotechnological Equipment, 2016
Self-incompatibility plays an important role in the fertilization of fruit species such as apricot. Apricot (Prunus armeniaca L.) shows gametophytic self-incompatibility, which is controlled by a multi-allelic S-locus.

Artificial Mutations in the Nuclear Gene Encoding Mitochondrial RNA Polymerase Restore Pollen Fertility in Cytoplasmic Male Sterile Tomato

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1414-1427, March 2026.
ABSTRACT Cytoplasmic male sterility (CMS) and restorer of fertility (Rf) are important traits in F1 hybrid breeding. However, the CMS/Rf system has not been used in tomatoes because of the limited resources of Rf lines. In this study, we performed mutagenesis in tomato CMS seeds and successfully obtained 13 suppressor mutants with pollen fertility ...

Control of gametophytic self-incompatibility in the African wild rice

, 2022
Abstract Self-incompatibility (SI) in the grass family (Poaceae) is controlled by a gametophytic two-locus system (S and Z). Recent studies have revealed several genes linked to the S and Z loci, but their roles remain largely unclear. Here, we discover that OlS1-HPS10 and OlS1-DUF247-1 control self-incompatibility of African wild rice (Oryza ...

Temperature‐dependent pollinator‐mediated selection on floral thermoregulation

New Phytologist, Volume 249, Issue 4, Page 1716-1726, February 2026.
Summary The thermal environment is one of the most pervasive agents of selection. Most plants cannot choose their microclimate, so understanding how they cope with thermal variability is of critical concern. Several floral traits can modify the floral thermal microenvironment, which may alleviate negative impacts of thermal extremes on gametophytes and
