THE EVOLUTION OF DISTYLY: POLLEN TRANSFER IN ARTIFICIAL FLOWERS [PDF]

open access: bronzeEvolution, 1994
A recent model by Lloyd and Webb derives conditions necessary for the evolution of distyly based on pollen-transfer probabilities between ancestral morphs and invading mutants. We used bumblebees visiting artificial flowers to measure the parameters of the model. Our findings supported the first evolutionary step proposed by the model, establishment of

On the evolution of distyly and morph ratio distortion in Lithospermum caroliniense [PDF]

open access: green, 2018
Natural History and EvolutionTwo conflicting models presently exist describing the evolutionary history of heterostyly, a condition in which there presents two morphs -- different plant sexual organ structure that some individuals within the same species

ROLE OF POLLINATORS IN THE EVOLUTION OF DIOECY FROM DISTYLY [PDF]

open access: bronzeEvolution, 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).

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 ...

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.

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.
