Divergent selection on flowering phenology but not on floral morphology between two closely related orchids

open access: yesEcology and Evolution, 2020
Closely related species often differ in traits that influence reproductive success, suggesting that divergent selection on such traits contribute to the maintenance of species boundaries. Gymnadenia conopsea ss.

Histone acetylation accompanied with promoter sequences displaying differential expression profiles of B-class MADS-box genes for phalaenopsis floral morphogenesis. [PDF]

open access: yesPLoS ONE, 2014
Five B-class MADS-box genes, including four APETALA3 (AP3)-like PeMADS2∼5 and one PISTILLATA (PI)-like PeMADS6, specify the spectacular flower morphology in orchids. The PI-like PeMADS6 ubiquitously expresses in all floral organs. The four AP3-like genes,

AN EVOLUTIONARY EXAMINATION OF THE FLORAL DISPLAY ofCATALPA SPECIOSA(BIGNONIACEAE) [PDF]

open access: yesEvolution, 1979
Those plant species that rely on animals to mediate the transfer of pollen usually attract pollinators with visual and/or aromatic stimuli and then reward them with pollen, nectar, or some other food (Faegri and van der Pijl, 1971; Proctor and Yeo, 1973).

Influence of group size and floral display on pollinator behaviour in Moricandia arvensis

open access: yesJournal of Pollination Ecology
Optimal foraging theory predicts that pollinators will visit dense floral patches over sparse ones. Understanding how the local abundance of floral resources influences pollinator behaviour is crucial for assessing the effect of floral traits on plant ...

Floral Humidity in Flowering Plants: A Preliminary Survey

open access: yesFrontiers in Plant Science, 2020
The area of space immediately around the floral display is likely to have an increased level of humidity relative to the environment around it, due to both nectar evaporation and floral transpiration.

Earlier spring snowmelt drives arrowleaf balsamroot phenology in montane meadows

open access: yesEcosphere, 2022
Climate change is shifting phenology globally, altering when and how species respond to environmental cues such as temperature and the timing of snowmelt.

Genetic basis and dual adaptive role of floral pigmentation in sunflowers

open access: yeseLife, 2022
Variation in floral displays, both between and within species, has been long known to be shaped by the mutualistic interactions that plants establish with their pollinators. However, increasing evidence suggests that abiotic selection pressures influence

Evolution and development of complex floral displays

open access: yesDevelopment
ABSTRACT Flowering plants – angiosperms – display an astounding diversity of floral features, which have evolved in response to animal pollination and have resulted in the most species-rich plant clade. Combinations of macroscale (e.g. colour, symmetry, organ number) and microscale (e.g.

Functional differentiation in pollination processes among floral traits in Serapias species (Orchidaceae)

open access: yesEcology and Evolution, 2017
Floral displays, influencing attractiveness to insects, increase the number of pollinator visits and the efficiency of each visit in terms of pollen exchange and thus affect the plant reproductive success.
