Assessment of Pollen Production, Pollen Viability, Autofertility and Paternal Success in Faba Bean (Vicia faba L.) for Better Exploitation of Grain Yield Heterosis

Plant Breeding, EarlyView.
ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

TCP24 modulates secondary cell wall thickening and anther endothecium development

Frontiers in Plant Science, 2015
miR319-targeted TCP genes are believed to regulate cell division in leaves and floral organs. However, it remains unknown whether these genes are involved in cell wall development. Here, we report that TCP24 negatively regulates secondary wall thickening

Taxonomic Revision of Corsia (Corsiaceae) Reveals Over‐Estimated Mycoheterotroph Diversity in Papuasia: 25 Species Become 10

Feddes Repertorium, Volume 137, Issue 3, September 2026.
ABSTRACT Corsia (Corsiaceae) is a remarkable genus of achlorophyllous, fully mycoheterotrophic plants distributed across New Guinea, the Solomon Islands, and Northern Australia. The genus has often been considered an example of adaptive radiation amongst mycoheterotrophic plants, with 25 narrowly endemic species, most known from just one or two ...

Genome-wide identification and analysis of the COI gene family in wheat (Triticum aestivum L.)

BMC Genomics, 2018
Background COI (CORONATINE INSENSITIVE), an F-box component of the Skp1-Cullin-F-box protein (SCFCOI1) ubiquitin E3 ligase, plays important roles in the regulation of plant growth and development.

The Function of the Partially‐Opened Spathe of Pinellia pedatisecta (Araceae) as a Pitfall Pollinator Trap

Plant Species Biology, Volume 41, Issue 4, July 2026.
Pinellia pedatisecta has a simplified inflorescence structure, compared to its congeners with highly specialized trap pollination systems. However, our study suggests that P. pedatisecta also captures and releases pollinating insects by the spathe movement during flowering season.

Pollination by long‐proboscid horseflies and its implications for reproductive isolation among coflowering Satyrium orchids in South Africa

American Journal of Botany, Volume 113, Issue 6, June 2026.
Abstract Premise Floral adaptations to pollinators can drive lineage diversification and promote coexistence of species. We investigated the reproductive biology of Satyrium longicolle, a South African orchid that we hypothesized to belong to a long‐proboscid horsefly pollination guild and examined overlap of pollinators and floral traits among ...

THE ROLE OF INVERTASES IN ANTHER DEHISCENCE [PDF]

The opening of anthers to release pollen (anther dehiscence) is a complex, regulated process. One of the mechanisms contributing to anther dehiscence is the active removal of water from anthers.

Variation in pollen limitation among reproductive modules points to likely resource reallocation in the alpine plant Veratrum grandiflorum

Nordic Journal of Botany, Volume 2026, Issue 6, June 2026.
Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual's ...

Rice SIZ1, a SUMO E3 ligase, controls spikelet fertility through regulation of anther dehiscence

, 2014
P>Sumoylation, a post-translational modification, has important functions in both animals and plants. However, the biological function of the SUMO E3 ligase, SIZ1, in rice (Oryza sativa) is still under investigation.
