Factors determining the diurnal dynamics of blooming of chosen plant species

open access: yesActa Agrobotanica, 2012
The paper attempts to synthesize the determinants which may influence the diurnal rhythm of blooming. Additionally, I tried to explore and bring together topics that concern blooming and have always been considered separately because of their origin in ...

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.

Contrasting bee pollination in two co-occurring distylic species of Cordia (Cordiaceae, Boraginales) in the Brazilian semi-arid Caatinga: generalist in C. globosa vs. specialist in C. leucocephala

open access: yesAnais da Academia Brasileira de Ciências, 2010
In this study we compare the reproductive biology of Cordia globosa and C. leucocephala (Cordiaceae, Boraginales; formerly referred to Boraginaceae) to understand the functioning of the floral morphs and the relations with their effective pollinators ...

The draft genome of Primula veris yields insights into the molecular basis of heterostyly [PDF]

open access: yes, 2014
BACKGROUND: The flowering plant Primula veris is a common spring blooming perennial that is widely cultivated throughout Europe. This species is an established model system in the study of the genetics, evolution, and ecology of heterostylous floral ...

Fruit set of distylous Psychotria carthagenensis Jacq. (Rubiaceae) mediated by Apis mellifera (Apidae) and species of Augochloropsis (Halictidae)

open access: yesActa Botânica Brasílica, 2015
Heterostyly is a floral polymorphism consisting in the presence of two morphs in the population that differ reciprocally in the position of their sexual organs.

SOME ASPECTS OF HETEROSTYLY [PDF]

open access: yesNew Phytologist, 1975
SUMMARYIt is suggested that the functional significance of each di/trimorphic structure in heterostyled flowers should be considered separately. The origin of the morphological and physiological components of heterostyly is discussed; it is suggested that the physiological incompatibility arose first and created conditions favouring selection of ...

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.

Structural and molecular analyses of heterostyly in Linum tenue (Linaceae) [PDF]

open access: yes, 2018
Flowering plant mating systems are as varied as they are complex, and are generally considered the leading force behind angiosperm diversity and evolution.

A short story gets longer: recent insights into the molecular basis of heterostyly

open access: yes, 2017
Heterostyly is a fascinating adaptation to promote outbreeding and a classical paradigm of botany. In the most common type of heterostyly, plants either form flowers with long styles and short stamens, or short styles and long stamens.

Pollen morphology and phylogenetic relationship of 14 Oxalis species

open access: yesGuangxi Zhiwu
Most Oxalis are highly ornamentally valuable, but their taxonomy is difficult, which greatly limits the landscape application of this genus. The pollen morphology and exine ornamentation of 14 species of the Oxalis were observed using scanning electron ...
