Pea aphids are genetically diverse, with different biotypes (or “host races”) having different host plant preferences. Sanchez-Arcos et al. reveal several relationships between plant metabolite production and the possibility of colonization of certain aphid host races. Using UHPLC- MS analysis of the extracts of Medicago sativa, Trifolium pratense, Vicia faba and Pisum sativum before and […]

About Laura Mejia
I’m fascinated about plant world. The processes that drive plants to produce metabolites that we use makes me realize that evolution is a phenomenon so complex but intriguing. Also I am interested in how people learn and how we can show to the public the results from our work. Beyond applications, we’re humans and our unique way of thinking could lead to something big.

Weeds represent a problem for the economy due to their easy resistance of pesticides, but they are also a model for adaptation, ecology and evolution. In this review Baucom focusses on three areas: the genetic basis of adaptation, evolutionary constraints, and experimental evolution. Weed resistance is related to mutations of target site resistance genes (e.g., […]
Understanding environmental stress in plants is undoubtedly important due to the consequences of climate change in crop productivity and survival of plants. Metabolomics based on liquid chromatography and gas chromatography coupled to mass spectrometry (LC-MS, GC-MS) allows an understanding of the metabolic profile changes of plants in response to stress. Fàbregas and Fernie review and […]
