Comparative Proteomic Analysis of Self‐Compatible Turnera Mutants Suggests Glutathione S‐Transferase 8 Is Involved in Overcoming S‐Morph Female Self‐Incompatibility Response

Plant Direct, Volume 9, Issue 12, December 2025.
ABSTRACT Distyly is a reproductive system, characterized by the presence of two floral morphs, which promotes outcrossing via physical and biochemical means. In distylous Turnera, the mating type of the S‐morph is determined by two genes: YUC6 (male) and BAHD (female).

Pollen morphology and phylogenetic relationship of 14 Oxalis species

Guangxi Zhiwu
Most Oxalis are highly ornamentally valuable, but their taxonomy is difficult, which greatly limits the landscape application of this genus. The pollen morphology and exine ornamentation of 14 species of the Oxalis were observed using scanning electron ...

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

The Plant Genome, Volume 18, Issue 4, December 2025.
Abstract 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 have been conducted using several genera including Petunia Juss., Nicotiana L., and Solanum ...

Reversibility of sex changes in the plant kingdom: more important than we thought?

Biological Reviews, Volume 100, Issue 6, Page 2199-2216, December 2025.
ABSTRACT Compared to animals, plants show a wide range of reproductive strategies with different degrees of sex separation (e.g. dioecy, monoecy, hermaphroditism). While sex expression was previously thought to be genetically determined and fixed in plants, accumulating evidence suggests that sex expression can change reversibly even within one ...

Reproductive systems of Hohenbergia Schult. & Schult.f. (Bromelioideae: Bromeliaceae) endemic to the Atlantic forest

Nordic Journal of Botany, Volume 2025, Issue 9, September 2025.
Many species of the Bromeliaceae are under threat due to the fragmentation and anthropogenic pressure affecting the Atlantic Forest highlight the need to conservation efforts. The genus Hohenbergia deserves special attention in this context, as the Hohenbergia stellata complex includes endemic species that rely on diverse reproductive strategies, which

Flower morphology, nectar features, and hummingbird visitation to Palicourea crocea (Rubiaceae) in the Upper Paraná River floodplain, Brazil

Anais da Academia Brasileira de Ciências, 2006
We investigated flower morphology, nectar features, and hummingbird visitation to Palicourea crocea (Rubiaceae), a common ornithophilous shrub found in the riparian forest understory in the Upper Paraná River floodplain, Brazil. Flowers are distylous and

Influence of sex‐organ positions on pollen transfer and self‐interference in plants with stylar polymorphisms: An experimental approach using three‐dimensional printed flowers

Functional Ecology, Volume 39, Issue 9, Page 2526-2538, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Heterostylous plants are defined by the reciprocal positioning of stigmas and anthers in floral morphs—a trait proposed by Darwin to enhance the efficiency of disassortative (intermorph) pollen transfer.

Genomic studies in Linum shed light on the evolution of the distyly supergene and the molecular basis of convergent floral evolution

New Phytologist, Volume 247, Issue 6, Page 2964-2981, September 2025.
Summary Distyly, an example of convergent evolution, is governed by a supergene, the S‐locus, in several species. Recent studies highlight similar genomic architectures of independently evolved S‐loci, but its mode of origin and whether similar regulatory pathways underlie the convergent evolution of distyly remains unclear.

Late-acting self-incompatibility and a narrow floral tube as underlying stylar dimorphism in Narcissus (Amaryllidaceae)

Ideas in Ecology and Evolution, 2018
Most heterostylous species show self- and intra-morph incompatibility and models established for such taxa have traditionally been applied to the evolution of stylar dimorphism and heterostyly in Narcissus, a genus with late-acting self-incompatibility ...
