Breeding biology and distyly in Palicourea rigida H. B. & K. (Rubiaceae) in the Cerrados of Central Brazil Biologia reprodutiva e distilia em Palicourea rigida H. B. & K. (Rubiaceae) em Cerrados do Brasil Central

open access: yesActa Botânica Brasílica, 2010
Distyly is a floral polymorphism more common among the Rubiaceae than in any other angiosperm group. Palicourea rigida is a typically distylous species of the Rubiaceae widely distributed in the Brazilian Cerrados.

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

open access: yesMol Biol Evol
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 ...

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

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.

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

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.

Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna. [PDF]

open access: yesBiol Rev Camb Philos Soc
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

THE EVOLUTION OF OUTCROSSING IN HIGHER PLANTS, WITH SPECIAL REFERENCE TO THE EVOLUTION OF DISTYLY

open access: yes, 1981
Models are developed for the evolution of outcrossing in general and the evolution of distyly in particular. Field studies of distylous Lithospermum cobrense (Boraginaceae) are reported to support and compliment theoretical work.
