Evolution of Autonomous Selfing in Marginal Habitats: Spatiotemporal Variation in the Floral Traits of the Distylous Primula wannanensis

Frontiers in Plant Science, 2021
Outcrossing plant species are more likely to exhibit autonomous selfing in marginal habitats to ensure reproduction under conditions of limited pollinator and/or mate availability.

Ancillary polymorphic floral traits between two morphs adaptive to hawkmoth pollination in distylous plant Tirpitzia sinensis (Linaceae)

BMC Plant Biology, 2022
Background Floral morphs are characterized differentiations in reciprocal positions of sexual organs and ancillary floral traits in heterostylous plants.

Floral intra‐individual variation differs between morphs and is linked to pollen deposition in self‐incompatible distylous plants

Plant Biology, EarlyView.
For most traits, floral intra‐individual variation was similar between morphs and populations with different pollinator guilds (bees and hummingbirds), potentially facilitating effective pollen transfer in distylous systems. Still, greater variation in corolla length increased pollen deposition in L‐morph flowers in the bee‐pollinated population ...

Road air pollution harms the reproductive success of a bee‐pollinated wildflower: A dusty threat to biodiversity

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1567-1571, September 2026.
Dust, a common form of air pollution, is particularly problematic on roadsides, which are important habitats for plants and pollinators. We investigated whether and how road dust affects plant sexual reproduction using Primula chungensis in a biodiversity hotspot. Our study provides compelling evidence that road dust can harm plant reproductive success

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.

Sources of variation in reciprocal herkogamy in the distyly floral syndrome of Linum tenue (Linaceae) [PDF]

, 2023
Distyly is a floral polymorphism involving reciprocal herkogamy shaped by selection for pollen transfer efficiency. The variation of the floral organs involved in pollen transfer can be individually affected by environmental and genetic sources of ...

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).

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.

Aspects of evolution and breakdown of distyly in Psychotria L. e Palicourea (Aubl) (Rubiaceae) species

, 2018
Flowering plants have several mating strategies. Distyly is one these breeding strategies, in which, plants present two floral morphs that occurs separately in a balanced ratio in each plant population.
