Research priorities for harnessing plant microbiomes in sustainable agriculture
Feeding a growing world population amidst climate change requires optimizing the reliability, resource use, and environmental impacts of food production. One way to assist in achieving these goals is… Expand
Distinct Leaf‐trait Syndromes of Evergreen and Deciduous Trees in a Seasonally Dry Tropical Forest
In seasonally dry tropical forests, tree species can be deciduous, remaining without leaves throughout the dry season, or evergreen, retaining their leaves throughout the dry season. Deciduous and… Expand
Fungal endophytes: modifiers of plant disease
Abstract Many recent studies have demonstrated that non-pathogenic fungi within plant microbiomes, i.e., endophytes (“endo” = within, “phyte” = plant), can significantly modify the expression of host… Expand
Common foliar fungi of Populus trichocarpa modify Melampsora rust disease severity.
Nonpathogenic foliar fungi (i.e. endophytes and epiphytes) can modify plant disease severity in controlled experiments. However, experiments have not been combined with ecological studies in wild… Expand
Prevalence of Tree Regeneration by Sprouting and Seeding Along a Rainfall Gradient in Hawai'i
Drought stress in tropical dry forests is thought to result in greater asexual regeneration via vegetative sprouting (e.g., basal, root, and branch layering) than occurs in moister tropical forests.… Expand
Genetics-based interactions among plants, pathogens, and herbivores define arthropod community structure.
Plant resistance to pathogens or insect herbivores is common, but its potential for indirectly influencing plant-associated communities is poorly known. Here, we test whether pathogens' indirect… Expand
Tree genotype mediates covariance among communities from microbes to lichens and arthropods
Summary 1. Community genetics studies frequently focus on individual communities associated with individual plant genotypes, but little is known about the genetically based relationships among… Expand
Differentiating genetic and environmental drivers of plant–pathogen community interactions
Summary Plant genotypic variation can shape associated arthropod and microbial communities locally, as has been demonstrated in controlled common garden experiments. However, the relative roles of… Expand
A Hypothetical Bottleneck in the Plant Microbiome
The plant microbiome may be bottlenecked at the level of endophytes of individual seeds. Strong defense of developing seeds is predicted by optimal defense theory, and we have experimentally… Expand
Multiple and interacting disturbances lead to Fagus grandifolia dominance in coastal New England
Abstract Recent studies have emphasized the importance of multiple and interacting disturbances in controlling plant community dynamics. However, detailed information on disturbance history and… Expand
