Effects of Manipulated Rainfall and Intraspecific Variation Within Dominant Species on Community Assembly: Insights From a Long-Term Grassland Restoration Experiment.

Grasslands converted to agricultural land use can be reestablished by sowing seeds of native species and temporal dynamics of diversity under altered climate can inform community assembly in the context of global change. We quantified three aspects of diversity (species richness, phylogenetic diversity, and functional diversity) in restored prairie plots sown with different ecotypes of two dominant grass species and manipulated rainfall to understand the relative importance of abiotic filtering and population source of dominant species on community assembly. We also evaluated the contributions of intra- and interspecific variations in functional traits across plots sown with different ecotypes of dominant species.

A chemical genetic screen with the EXO70 inhibitor Endosidin2 uncovers potential modulators of exocytosis in Arabidopsis.

Exocytosis plays an essential role in delivering proteins, lipids, and cell wall polysaccharides to the plasma membrane and extracellular spaces. Accurate secretion through exocytosis is key to normal plant development as well as responses to biotic and abiotic stresses. During exocytosis, an octameric protein complex named the exocyst facilitates the tethering of secretory vesicles to the plasma membrane.

Transcriptional repression of under water-deficit stress promotes anthocyanin biosynthesis to enhance drought tolerance.

The transcription factor GT2-LIKE 1 (GTL1) has been implicated in orchestrating a transcriptional network of diverse physiological, biochemical, and developmental processes. In response to water-limiting conditions, GTL1 is a negative regulator of stomatal development, but its potential rolein other water-deficit responses is unknown. We hypothesized that GTL1 regulates transcriptome changes associated with drought tolerance over leaf developmental stages.

has no competitive responses to neighbors: A case study in (non)reproducible plant biology.

Plant-plant competition is ubiquitous in nature. However, studying below ground behavior of roots has always posed certain difficulties. Pea ( L.

species infecting maize and other grass species in the Americas represents a complex of closely related species.

The genus contains numerous obligate fungal parasites that produce raised, melanized structures called stromata on their plant hosts referred to as tar spot. Members of this genus are known to infect many grass species but generally do not cause significant damage or defoliation, with the exception of . which has emerged as an important pathogen of maize throughout the Americas, but the origin of this pathogen remains unknown.

Insects and their Laboulbeniales (Ascomycota, Fungi) of Lake Eustis and Emeralda Marsh Conservation Area: A case study on urbanization and diversity.

A rapid biodiversity assessment of insects and associated Laboulbeniales fungi was conducted over the course of five nights in August, 2018, at two central Florida lakes: Lake Eustis and the nearby protected and restored National Natural Landmark, Emeralda Marsh Conservation Area (EMCA), which encompasses a portion of Lake Griffin. Lake Eustis was surveyed for Laboulbeniales in 1897 by mycologist Dr. Roland Thaxter but has not since been investigated.
