Evolution of Autonomous Selfing in Marginal Habitats: Spatiotemporal Variation in the Floral Traits of the Distylous Primula wannanensis

Frontiers in Plant Science, 2021
Outcrossing plant species are more likely to exhibit autonomous selfing in marginal habitats to ensure reproduction under conditions of limited pollinator and/or mate availability.

Retracing the molecular basis and evolutionary history of the loss of benzaldehyde emission in the genus Capsella [PDF]

, 2019
The transition from pollinator‐mediated outbreeding to selfing has occurred many times in angiosperms. This is generally accompanied by a reduction in traits attracting pollinators, including reduced emission of floral scent.

Effect of gradual pollen presentation on pollination efficiency and reproduction of Vaccinium corymbosum Berkeley in two habitats

Frontiers in Ecology and Evolution
IntroductionGradual pollen presentation is a reproductive strategy for plants to improve the efficiency and accuracy of pollen export and acceptance as well as to promote outcrossing.

Multiple aspects of the selfing syndrome of the morning glory Ipomoea lacunosa evolved in response to selection: A Qst‐Fst comparison

Ecology and Evolution, 2019
The frequent transition from outcrossing to selfing in flowering plants is often accompanied by changes in multiple aspects of floral morphology, termed the “selfing syndrome.” While the repeated evolution of these changes suggests a role for natural ...

Navigating the Ethereal Tightrope: The Nanogenerator Manipulates Neurons for Immune Equilibrium

Advanced Science, EarlyView.
This review explores how nanogenerators modulate neuroimmune responses, offering innovative strategies for treating neurological disorders. By interfacing with neural pathways, they enable precise control of immune activity, especially via vagus nerve stimulation.

Gut Microbiota‐Non‐Coding RNA Axis in Immune Modulation and Disease: From Mechanisms to Clinical Translation

Advanced Science, EarlyView.
ABSTRACT Immune homeostasis is indispensable for preserving organismal integrity, orchestrated through complex molecular networks encompassing immune cell dynamics, microbial cues, and epigenetic regulation. Among these, the gut microbiota‐non‐coding RNA (ncRNA) axis has recently garnered substantial attention as a multifaceted modulator of host ...

Floral attraction and flower visitors of a subcanopy, tropical rainforest tree, Fontainea picrosperma

Ecology and Evolution, 2021
Flowering plants in tropical rainforests rely heavily on pollen vectors for successful reproduction. Research into pollination systems in tropical rainforests is dominated by canopy species, while subcanopy plant–pollinator interactions remain under ...

Chasmogamy and entomophily in Burmannia disticha (Burmanniaceae)

Frontiers in Plant Science, 2023
Burmannia shows a set of floral traits that suggest elaborate mechanisms of animal-mediated pollen transfer. These include flower coloration, septal nectaries and a long and narrow floral chamber.
