Research Interests

Global climate change and population growth are two major challenges of the 21st century. Crop losses due to variable weather patterns associated with climate change has risen over the past decades, and climate models predict an increased incidence particularly of floods, droughts, and extreme temperatures. This situation together with the growing food demand is anticipated to pose a real threat to global food security. It is therefore vital to develop strategies to substantially improve food availability in variable environments, and ultimately, transfer this knowledge to farmers in the time frame needed. This has been progressively accomplished through breeding and biotechnology approaches that use innovative methods to develop plants with enhanced abiotic stress tolerance.

Although much progress has been done over the past years in the area of plant abiotic stress, the mechanisms defining plant resilience to variable environments are still not completely understood. One approach to improve our knowledge of plant tolerance to abiotic stress is to reveal the underlying central metabolic pathways (i.e., carbon, nitrogen, and energy metabolism) that play an important role in modulating their growth, development, and stress responses. This information will ultimately provide the knowledge basis to facilitate our understanding of the plant’s flexibility to reconfigure these primary metabolic pathways to sustain cellular homeostasis thereby ensuring their survival in adverse conditions.

At the Plant Metabolomics Laboratory we employ metabolomics workflows grounded on selective metabolite extractions and high-throughput mass spectrometry (MS)-based technologies that combine liquid chromatography and gas chromatography coupled to MS (LC-MS, GC-MS) to provide a comprehensive view of the plant metabolome in response to abiotic/biotic-stress factors.

Laboratório de Metabolómica de Plantas (PT)

O Laboratório de Metabolómica de Plantas usa a Química Analítica e a Espectrometria de Massa para estudar os mecanismos metabólicos subjacentes às respostas das plantas a várias perturbações genéticas e/ou ambientais (fatores abióticos/bióticos). Em condições ambientais adversas, a planta responde e adapta-se através de mecanismos regulatórios, tais como alteração do metabolismo celular (e.g., acumulação de solutos compatíveis). A identificação das respostas ao nível metabólico que promovem ou mantêm o crescimento e desenvolvimento das plantas durante condições ambientais adversas é uma componente extremamente importante em aplicações biotecnológicas para o desenvolvimento de variedades de plantas mais tolerantes.
