Bract size affects resource availability and fruit set in a hummingbird-pollinated plant with distyly polymorphism. [PDF]

open access: yesPlant Biol (Stuttg)
In Psychotria poeppigiana, larger bracts honestly signal greater nectar availability but have higher mortality, while smaller bracts produce more fruit, revealing a surprising trade‐off and hints of sexual role specialization in this distylous species. Abstract Plants can use non‐floral signals to advertise the presence of resources to pollinators. The

Evolution of distyly breakdown in Palicoureeae Robbr. & Manen and Psychotrieae Cham. & Schltdl. (Rubiaceae)

open access: yesActa Botânica Brasílica, 2022
Distyly is a floral polymorphism with reciprocal placement of male and female structures, heteromorphic self-incompatibility, and other ancillary traits. However, breeding system breakdowns and loss of polymorphism are common.

Multiple Glacial Refugia and Complex Postglacial Dynamics of <i>Primula sikkimensis</i> (Primuaceae) in the Heterogeneous Qinghai-Tibet Plateau. [PDF]

open access: yesEcol Evol
Primula sikkimensis persisted in distinct glacial refugia within the Hengduan Mountains and eastern Himalayas during the Last Glacial Maximum. Subsequent postglacial range expansions onto the Qinghai–Tibet Plateau were accompanied by secondary contact and interspecific hybridization, collectively enhancing genetic diversity and adaptive capacity. These

Is distyly in subtropical Psychotria brachyceras (Rubiaceae) similar to the general trends observed for the genus?

open access: yesActa Botânica Brasílica, 2022
Distyly is a floral polymorphism that promotes cross-pollination through precise pollination. Psychotria is a mostly tropical genus of distylous Rubiaceae.

Cordia subcordata (Boraginaceae), a distylous species on oceanic coral islands, is self-compatible and pollinated by a passerine bird [PDF]

open access: yesPlant Ecology and Evolution, 2020
Background and aims – Distyly is usually rare on oceanic islands, which is probably due to the difficulty for distylous plants to colonize those islands.

Genetic Causes and Genomic Consequences of Breakdown of Distyly in Linum trigynum. [PDF]

open access: yesMol Biol Evol, 2023
Abstract Distyly is an iconic floral polymorphism governed by a supergene, which promotes efficient pollen transfer and outcrossing through reciprocal differences in the position of sexual organs in flowers, often coupled with heteromorphic self-incompatibility.

Discovery of distyly in Narcissus (Amaryllidaceae) [PDF]

open access: yesAmerican Journal of Botany, 2000
There has been disagreement concerning the nature of sexual polymorphisms in Narcissus, a genus of insect‐pollinated geophytes native to the Mediterranean. The existence of trimorphic heterostyly in the genus has recently been confirmed, but the occurrence of distyly remains enigmatic.

Crop yield mediated by honeybees in a star fruit orchard exhibiting atypical distyly

open access: yesActa Botânica Brasílica, 2021
The dependence of commercial crops on pollinators is closely related to their reproductive strategies and has direct impacts on production yields. Fruit production of Averrhoa carambola, the star fruit, is highly dependent on bee pollination.

Role of Pollinators in the Evolution of Dioecy from Distyly [PDF]

open access: yesEvolution, 1980
Distylous flowering plant species are characterized by having two types of individuals that bear different forms of flowers: "pin" flowers with long styles and short stamens and "thrum" flowers with short styles and long stamens (Darwin, 1877; Frankel and Galun, 1977).

Phosphoproteomic analysis of distylous Turnera subulata identifies pathways related to endoreduplication that correlate with reciprocal herkogamy. [PDF]

open access: yesAm J Bot
Abstract Premise A multi‐omic approach was used to explore proteins and networks hypothetically important for establishing filament dimorphisms in heterostylous Turnera subulata (Sm.) as an exploratory method to identify genes for future empirical research.
