Domestication During Restoration: Unintentional Selection During Eight Generations of Wild Seed Propagation Reduces Herkogamy, Dichogamy and Heterozygosity in Clarkia pulchella

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Seed production on native seed farms has increased to meet the rising demand for plant material for restoration. Although these propagation efforts are necessary for restoration, cultivating wild populations may also result in unintentional selection and elicit evolutionary changes that mimic crop domestication, essentially turning these ...

Isolamento, armazenamento e determinação da colonização por fungos “dark septate” a partir de plantas de arroz. = Isolation, storage and determination of fungal colonization “dark septate” from rice plants.

open access: yesAgro@mbiente On-line, 2011
Endophyte fungi known as DSEF can be plant-growth-promoting. Aiming to improve a methodology for the isolation, storage and determine the rice roots colonization by “dark septate”, a study was developed based on the achievement of these microorganisms in

The Evolution of Locally Adaptive Chromosome Inversions in Mimulus guttatus

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Chromosomal inversion polymorphisms are ubiquitous across the diversity of diploid organisms and play a significant role in the evolution of adaptations in those species. Inversions are thought to operate as supergenes by trapping adaptive alleles at multiple linked loci through the suppression of recombination. While there is now considerable

The Evolutionary Dynamics of Genetic Mutational Load Throughout Tomato Domestication History

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Understanding the impact of domestication on deleterious mutations has fascinated evolutionary biologists and breeders alike. A ‘cost of domestication’ has been reported for some organisms through accumulation of gene disruptions or radical amino acid changes.

Reactive oxygen species act as signaling molecules to control root hair initiation and tip growth

open access: yesNew Phytologist, EarlyView.
Summary Root hairs (RHs) increase the surface area of roots, facilitating nutrient and water uptake and plant anchorage. RHs form from root epidermal cells and elongate by polar tip growth. Reactive oxygen species (ROS) have recently been implicated as important signals that drive RH formation and elongation using both genetic and imaging approaches ...

TIR innovations in plant immunity

open access: yesNew Phytologist, EarlyView.
Summary Toll/interleukin‐1 receptor (TIR) domain‐containing immune receptors are crucial for plant immunity, with recent advancements highlighting the enzymatic functions of TIR domains and their production of signaling molecules. TIR‐catalyzed compounds interact with receptors to form functional modules that trigger the oligomerization of helper ...

Rhizobacteria prime the activation of plant defense and nutritional responses to suppress aphid populations on barley over time

open access: yesNew Phytologist, EarlyView.
Summary Interactions between plants and soil microbes are widespread and are documented to modulate plant–insect herbivore interactions. Still, it remains unclear how these shape the overall plant defense responses and the mechanisms in suppressing insect populations.
