Major drivers of genetic differentiation in Iberian Arabidopsis thaliana

MathematicsPlant biology

By BCAM

Populations are not static, and the geographic distribution of genetic diversity within and among populations is changing continuously. The drivers of genetic differentiation is one of the cornerstones in evolution, as genetic diversity is paramount for the ability of populations to adapt and persist in changing environments. The spatio-temporal changes in genetic diversity constantly taking […]

The history of Earth climate is characterized by a succession of glacial and interglacial periods. However, although climate change is inherent to Earth, the observed trend of temperature increase over the past century cannot be explained by climate models which include solar irradiance and are only explicable by the rise in greenhouse gases. Mauna Loa […]

Naturalists and scientists have been collecting plants or plant parts during centuries to make collections and catalogues known as herbaria (sing. herbarium) that have been traditionally used for comparative taxonomy and systematics research. The first herbarium collections were compiled along with the foundation of botanical gardens during the first half of the 16th century. The […]

Author: Teresa E. Gimeno is an Ikerbasque Research Fellow at The Basque Centre for Climate Change One of the expected effects of rising atmospheric CO2 concentration in the atmosphere is an increase in plant water use efficiency. This is due to the expected enhancement of photosynthesis under future atmospheric CO2 concentrations, together with a partial […]

Plant biology

Plants emit a great amount of volatile organic compounds (VOCs). They are mainly produced in flowers and fruits and confer them their classical pleasant smell. However, leaves and roots also emit an important quantity of volatiles. VOCs have different functions mostly related with the communication of the plant with the environment. They are responsible of […]

Every organism, from virus to animals need nitrogen (N) to live; indeed, nucleic acids and proteins are made out with N. Nearly all of these organisms, fulfill their nitrogen needs taken up N from the environment in reduced forms, usually as nitrate (NO3–), ammonium (NH4+) or amino acids. Interestingly, certain microorganisms, known as diazatrophs, have […]
