How pollen tubes fight for food: the impact of sucrose carriers and invertases of Arabidopsis thaliana on pollen development and pollen tube growth

Frontiers in Plant Science, 2023
Pollen tubes of higher plants grow very rapidly until they reach the ovules to fertilize the female gametes. This growth process is energy demanding, however, the nutrition strategies of pollen are largely unexplored.

Land birds on atolls: diversity, origin, and function

Biological Reviews, EarlyView.
ABSTRACT Oceanic islands are global hotspots of avian biodiversity and endemism. Their isolation and distinct environmental conditions have uniquely shaped the evolutionary trajectories of island birds, while, in turn, land bird communities have become critical providers of ecological functions to island ecosystems.

Combining phenotypic, physiological, and multi‐omics studies to provide new insights on the role of 2,4‐epibrassinolide in regulation of seed shattering in Elymus sibiricus L.

Grassland Research, EarlyView.
Abstract Background Seed shattering limits the production of Elymus sibiricus L., and application of exogenous brassinosteroid significantly alleviates plant organ abscission. Methods To explore the potential regulatory network of brassinosteroid on seed shattering, the abscission zone of E. sibiricus cv. Lanyu No.

The plant microbiome: From ecological foundations to precision microbial engineering for sustainable agriculture

iMeta, EarlyView.
From ecological principles to precision engineering of plant microbiomes for sustainable agriculture. The plant holobiont integrates diverse microbial niches (including rhizosphere, endosphere, phyllosphere, seed, and aerial‐root mucilagesphere), host genetics (namely M genes), and host metabolites. Furthermore, molecular dialogues, including rhizobial

Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

Pollen thermotolerance of a widespread plant, Lotus corniculatus, in response to climate warming: possible local adaptation of populations from different elevations [PDF]

PeerJ
One of the most vulnerable phases in the plant life cycle is sexual reproduction, which depends on effective pollen transfer, but also on the thermotolerance of pollen grains.

The disruption of seed dispersal networks: disentangling the effects of habitat loss and fragmentation

Oikos, EarlyView.
Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Pollen Germination and Tube Growth in Northern Highbush Blueberry are Inhibited by Extreme Heat

HortScience, 2023
The increasing intensity and frequency of extreme heat events threaten crop productivity globally. Certain phases of plant reproduction necessary for fertilization are highly sensitive to extreme heat, particularly during pollen development, germination,

Feast or famine: How food deserts, wealth and greenspace correlate with coyote diets in Seattle, Washington

People and Nature, EarlyView.
Abstract Urban environments create unique challenges for wildlife, where dietary habits may reflect both ecological heterogeneity and societal disparities. In this study, we explored how social factors such as household income and human population density, and ecological factors such as tree canopy correlate with coyote (Canis latrans) diets in Seattle,

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.
