Pollination syndromes in a specialised plant‐pollinator interaction: does floral morphology predict pollinators in Calceolaria?

Plant Biology, 2014
AbstractPollination syndromes are defined as suites of floral traits evolved in response to selection imposed by a particular group of pollinators (e.g., butterflies, hummingbirds, bats). Although numerous studies demonstrated their occurrence in plants pollinated by radically different pollinators, it is less known whether it is possible to identify ...

Effective pollinators of Asian sacred lotus (Nelumbo nucifera): contemporary pollinators may not reflect the historical pollination syndrome [PDF]

Annals of Botany, 2009
If stabilizing selection by pollinators is a prerequisite for pollinator-mediated floral evolution, spatiotemporal variation in the pollinator assemblage may confuse the plant-pollinator interaction in a given species. Here, effective pollinators in a living fossil plant Nelumbo nucifera (Nelumbonaceae) were examined to test whether beetles are major ...

The genetic mechanisms underlying the convergent evolution of pollination syndromes in the Neotropical radiation of Costus L.

Frontiers in Plant Science, 2022
Selection together with variation in floral traits can act to mold floral form, often driven by a plant’s predominant or most effective pollinators. To investigate the evolution of traits associated with pollination, we developed a phylogenetic framework

The Spatiotemporal Genetic Architecture of Seed Vigor in Upland Cotton

Advanced Science, EarlyView.
Leveraging the semi‐automated SeedRanger platform, we profiled the germination kinetics of 356 cotton accessions at a 30‐min interval. This high‐throughput phenomic approach delineated a temporal genetic network comprising 541 stage‐specific loci. Crucially, functional validation identified FLA2 as a pivotal, auxin‐modulated regulator that orchestrates

Causal‐Guided Ultra‐Long‐Term Time Series Forecasting Via Anticipated Covariates

Advanced Science, EarlyView.
Often treated as unknown, information from the future remains underutilized.We demonstrate that in a coupled dynamical system, providing the future state of the effect enables accurate forecasting of the cause for a long timesteps. A time series forecasting paradigm that introduces anticipated covariates to represent such known future states is ...

Interactions between maternal provisioning and natural selection on seed mass fluctuate across heat waves

American Journal of Botany, EarlyView.
Abstract Premise Changing climates are leading to more frequent and severe heat waves, potentially threatening plant populations. Both acclimation to stress and selection for heat‐escape or heat‐resistance phenotypes occur during heat waves. However, plastic responses and selection do not necessarily interact cohesively—even producing trait responses ...

Generalization versus specialization in pollination systems: visitors, thieves, and pollinators of Hypoestes aristata (Acanthaceae).

PLoS ONE, 2013
Many recent studies have suggested that the majority of animal-pollinated plants have a higher diversity of pollinators than that expected according to their pollination syndrome.

Potential of Bee Pollen as a Nutraceutical And/Or Functional Ingredient for Metabolic Syndrome Management: In Vitro Antioxidant, Anti‐Inflammatory, and Digestive Enzyme Inhibitory Activities

Food Chemistry International, EarlyView.
Bee pollen samples from China and Spain exhibited in vitro antioxidant, anti‐inflammatory, and digestive enzyme inhibitory activities due to their composition, suggesting their potential as a nutraceutical or functional ingredient to help counteract oxidative stress, chronic inflammation, and metabolic disorders.

Gradual pollen presentation in Vaccinium corymbosum ‘Bluecrop’: an adaptive mechanism to improve pollination efficiency and outcrossing [PDF]

PeerJ
Gradual pollen presentation is a plant reproductive mechanism to improve pollination efficiency and accuracy and promote outcrossing. Vaccinium corymbosum ‘Bluecrop’ has a typical gradual pollen presentation mechanism.

Engineering compact Physalis peruviana (goldenberry) to promote its potential as a global crop

PLANTS, PEOPLE, PLANET, EarlyView.
Goldenberry (Physalis peruviana) produces sweet, nutritionally rich berries, yet like many minor crops, is cultivated in limited geographical regions and has not been a focus of breeding programs for trait enhancement. Leveraging knowledge of plant architecture‐related traits from related species, we used CRISPR/Cas9‐mediated gene editing to generate a
