The Red Queen unveils the sexual and mating strategies of flowers

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

Evolution of crop phenotypic spaces through domestication

open access: yesNew Phytologist, Volume 250, Issue 3, Page 1948-1963, May 2026.
Summary We used domestication as an in vivo replicated experiment to investigate how divergent selection has shaped the evolution of multivariate phenotypic spaces. We measured 11–57 qualitative and quantitative traits in 13 species, either unique or shared between species, and established a framework for cross‐species comparisons. Our results revealed

A Global Analysis of the Distribution Patterns of Style‐Length Polymorphisms Across Angiosperms

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This study tested the tropicality‐ and diversity‐driven hypotheses to explain the global distribution of style‐length polymorphisms (SLP) in angiosperms. Phylogenetic logistic regression revealed that although SLP occurrence was associated with tropical regions, this pattern was driven by the predominantly tropical family Rubiaceae and disappeared once

A New Insight Into Pollen Release and Presentation in Actinidiaceae Plants: The Case Study of Dioecious Actinidia arguta

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
In this study, indoor and field observation methods were employed to conduct a tracking investigation on the anther dehiscence mode, pollen presentation strategy of male, and the floral characteristics and pollination traits of both female and male.

Arisaema siahaense sp. nov. (Araceae) from India

open access: yesNordic Journal of Botany, Volume 2026, Issue 4, April 2026.
A new species of Arisaema Mart. (Araceae) belonging to sect. Fimbriata is described and illustrated here from the Siaha District, Mizoram, India. This new species is characterized by an evergreen, dioecious herbaceous habit, up to 1.08 m high, having a subglobose tuber, with a solitary trifoliate leaf.

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

open access: yesTAXON, 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.

Occurrence of Intersex in the Marine Mussel Perumytilus purpuratus (Mollusca: Bivalvia): Does Gonadal Parasitism Play a Role?

open access: yesBiology
Intersexuality is a reproductive phenomenon that occurs in some gonochoric species and refers to the simultaneous presence of both male and female gametes within the same individual.

Conservation Genetics of Threatened, High Ploidy Lepidium (Brassicaceae) Species From Vulnerable Inland Habitats, South Island, New Zealand

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 1, March 2026.
Genetic variation in three endangered allopolyploid Lepidium species was assayed using amplicon sequencing of 16 nuclear genesand phylogenetic analysis to distinguish ortholog/paralog (homoeolog) relationships. After phylogenetic analysis, the 16 sets of gene sequences were scored as co‐dominant alleles at a total of 55 putative loci in the target ...

Nucleo-Cytoplasmic Male Sterility and Alternative Routes to Dioecy [PDF]

open access: yesEvolution, 1994
Population-genetic models of nucleo-cytoplasmic gynodioecy are shown to allow invasion of males and conversion to dioecy in a single cytotype. Pleiotropic effects of restorer alleles on fertility through male or female function can maintain a cytoplasmic polymorphism in a population that prevents evolution to dioecy regardless of the pollen fertility ...
