SPA (SUPPRESSOR OF PHYTOCHROME A-105) proteins form a complex with COP1 (CONSTITUTIVELY PHOTOMORPHOGENIC 1) and are required for COP1 to respond to changes in the light environment and transduce light signals and influence plant development. In this paper, Balcerowicz et al. investigated the importance of SPA proteins in the COP1/SPA complex. Using fluorescence, they could […]
Arabidopsis thaliana is a good study system to shed light on evolutionary processes. Its broad native range and genetic diversity provide resources to study speciation and local adaptation. Durvasula et al. studied the early history and transition to selfing of this species by comparing genome sequences of populations native to Eurasia and Africa. They found […]
Environmental changes affect the biodiversity (variety of life forms) and productivity (conversion of sunlight energy and carbon into plant biomass) of ecological communities. The collaborative Nutrient Network (NutNet) was created 10 years ago with the goal of synthesizing studies of ecosystem environmental responses (mainly of grasslands) and tackling their shortcomings. This review by Borer et […]
Pollination is an important evolutionary process as it allows gene flow. If pollen travels long distances, the likelihood of inbreeding is reduced and fitness may be increased. Pollen dispersal can be assisted by pollinators, and although most plants are pollinated by insects, birds are also important and contribute to pollination of around 500 vascular plant […]
Crop domestication has been accompanied by the evolution of aggressive weedy crop relatives that compete for resources and make weed management a challenge. By using whole-genome sequencing of the two most commonly found weedy rice strains in the US (SH and BHA), and comparing them with the genomes of several accessions of cultivated rice, wild […]
Omics approaches have helped shed light on how plants relate to their environment and how they respond to changes in it. Although still relatively underutilized, comparative transcriptomics and proteomics approaches also can be applied to study mechanisms of plant adaptation. Voelckel et al. discuss the pros and cons of using omics approaches to study adaptability, […]
“Reporting science clearly and accurately is a fundamental part of the scientific process, facilitating both the dissemination of knowledge and reproducibility of results.” In this way, Plavén-Sigray et al. introduce us to their preprint in which they analyzed readability in over 700,000 abstracts of scientific articles published in 122 biomedical journals from 1881-2015. Using two […]
Speciation events result from a combination of molecular, environmental and stochastic (random) factors. Several models developed in the last 150 years help to explain how species emerge, but more recently evolutionary developmental biology (evo-devo) approaches give us tools to decipher plant speciation. In this review, Fernández-Mazueco and Glover show us the available evidence, from macro- […]
A great variety of plants rely on pollinators to be fertilized successfully. This close relationship is thought to drive evolutionary diversification in plants, making the presence or absence of pollinators in response to climate change an increasingly relevant matter. Gervasi and Schiestl addressed the question of how pollinators influence real-time evolution of adaptive traits in […]
