Célia Miguel Lab
At the Forest Biotech Lab we are studying aspects of forest tree biology which are important to understand and improve characteristic features such as wood and cork formation, or resilience to specific stresses. We are also developing genomic resources and tools to support forest tree research and potential applications.

Forest trees dominate many terrestrial ecosystems and their relevance for social and economic activities is unquestionable. The forest-based sector significantly contributes to the EU’s total manufacturing added value, and provides income and jobs for millions of people. Efficient strategies for improving forest productivity and resilience are required in order to meet the increasing demand for forest products. Yet, tree selection and improvement programs addressing these issues are still incipient or inexistent for many important forest tree species.
At the Forest Biotechnology Lab we are studying aspects of tree biology and biotechnology underlying traits of interest for tree selection, improvement and propagation. Three main research lines are being addressed including (i) the regulation of plant secondary growth, which is at the basis of wood and cork formation, and is responsible for the production of most of the terrestrial plant biomass; (ii) embryogenesis and reproduction in conifers (gymnosperms), for understanding basic molecular mechanisms regulating embryo development, and generating knowledge for the optimization of large-scale clonal propagation of pines; (iii) establishment of tools and resources in tree molecular biology and genomics, for supporting downstream research and applications in breeding. More recently, taking advantage of the developed resources, we have been collaborating with other groups for the characterization of tree responses to specific stresses significantly affecting the Portuguese forests, such as the pine wilt disease caused by the pine wood nematode.
The species we work with include the maritime pine, cork oak, and models such as Populus and Arabidopsis. Our studies at the molecular regulation level, have been mainly targeting transcription factors and small non-coding RNAs as well as their crosstalk to hormones.

Biotecnologia Florestal (PT)
As árvores florestais representam um recurso de elevado valor económico, ambiental e social. No nosso laboratório investigamos alguns aspectos da biologia do desenvolvimento e biotecnologia com potencial relevância para a valorização de espécies florestais representativas em Portugal. Estamos interessados na caracterização de reguladores moleculares da formação da madeira e da cortiça, e estudamos também o desenvolvimento dos embriões de pinheiro para melhorar a propagação vegetativa (clonagem) desta espécie. Colaboramos ainda com outros grupos para caracterização das respostas das árvores a condições específicas de stress que afectam as florestas portuguesas, tais como a infecção pelo nemátode da madeira do pinheiro. Estamos ainda envolvidos em projectos nacionais e internacionais para o desenvolvimento de ferramentas e recursos úteis para a investigação das árvores florestais e suas aplicações, sendo exemplos disso o genoma e transcritoma de espécies como o pinheiro bravo e o sobreiro.
