Dispersal and delimitation: Phylogenomics of Connaraceae prompts revised generic delimitation in Cnestideae and reveals global biogeographic patterns

TAXON, Volume 75, Issue 2, April 2026.
Abstract The tempo and mode of assembly of the world's most diverse, tropical floras remain poorly known. Evolutionary relationships within pantropical plant clades such as Connaraceae (Oxalidales, ca. 220 species) offer an opportunity to address this issue.

First whole genome sequence of a diploid crop wild relative of the Andean tuber “oca”: Annotation and comparative genomic analysis of Oxalis oulophora

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Oxalis oulophora, a diploid species closely related to the octoploid Andean tuber crop oca (Oxalis tuberosa), was selected for whole‐genome sequencing to aid in understanding the origins of polyploidy and domestication in oca and its relatives (crop wild relatives).

Ecological correlates and genetic consequences of evolutionary transitions from distyly to homostyly [PDF]

Annals of Botany, 2017
The outbreeding floral polymorphism heterostyly frequently breaks down, resulting in the evolution of self-fertilization as a result of homostyle formation. Here, the loss of floral polymorphism in distylous Primula oreodoxa, a sub-alpine species restricted to western Sichuan, China, was examined by investigating the ecological correlates and genetic ...

Revision of Manettia (Rubiaceae) in Paraguay

Nordic Journal of Botany, Volume 2026, Issue 2, February 2026.
Manettia Mutis is a Neotropical genus comprising over 100 species, many of which are only known from their original descriptions or, at most, from revisions dating back over 100 years. Recent review studies have remained unpublished for several years. Conventional taxonomic methods are followed.

Is there interspecific fruit set in distylous, synchronopatric species of Erythroxylum P. Browne (Erythroxylaceae)? [PDF]

Brazilian Journal of Biology
Sympatric congeneric species that overlap the flowering period and have morphologically similar flowers tend to be pollinated by the same groups of pollinators, facilitating interspecific pollination and hybridization.

Morphological Characteristics and Identification of Key Genes Regulating Distyly Morph in Primula vulgaris

Agronomy
The Primula vulgaris, belonging to the genus Primula, is a typical distyly. The distyly is an important morphological feature in nature. However, there is a shortage of research on the causes of distyly formation and the associated genes that control ...

A pan‐European citizen science study shows population size, climate and land use are related to biased morph ratios in the heterostylous plant Primula veris

Journal of Ecology, Volume 114, Issue 1, January 2026.
A large‐scale citizen science study involving thousands of cowslip (Primula veris) observations from all over Europe revealed an unexpected prevalence of S‐morphs over L‐morphs, which was influenced by climatic as well as land use factors. Furthermore, general morph ratios were often unbalanced with the strongest shifts occurring in smaller populations.

Genomic analyses of the Linum distyly supergene reveal convergent evolution at the molecular level

Current Biology, 2022
Abstract Supergenes govern balanced polymorphisms in a wide range of systems. The reciprocal placement of stigmas and anthers in pin and thrum floral morphs of distylous species constitutes an iconic example of a balanced polymorphism governed by a supergene, the distyly S- locus ...
