I’ve finished my Biology degree, specialized in Biology in 2007 and immediately fallowed in my master thesis in Cellular Biology and Biotechnology in 2007. I attained my master degree, in 2009, with the thesis “Study of the photosynthetic response to drought stress in AOX mutants of Arabidopsis thaliana“. In 2010 I enrolled as a grantee holder in the project VITISMULTISTRESS in which I mastered several plant physiology techniques. In 2013 I was awarded a four year PhD grant by Fundação para a Ciência e Tecnologia (FCT). During this period I started and developed my work on “Vitis vinifera sex genes: from the wild to the domesticated varieties”. Cultivated grapevines are hermaphrodites (although some female cultivars exist) and plants exhibit complete and perfect flowers. Grapevine was an interesting system to study specific aspects of reproductive development and, since it lack sex chromosomes. On the other hand the wild ancestor of the cultivated grapevine, Vitis sylvestris is a dioecious species with male and female individuals. To unravel the locus for flower sex formation combination of bioinformatics and molecular biology techniques was used and I was able to pinpoint genes that are involved in the synthesis of the pollen wall components in the female pollen, potentially making it infertile. He also showed that carpel abortion in male plants seems to be due to deficient phytohormones signaling. Alongside these results two genetic markers were developed that when used in combination allows the early identification of male, female and hermaphrodite plants. The F1 offspring segregation of these two markers showed that these are linked to flower type. In January 2018, after completing my PhD thesis I joined the Mycovitis project and used my expertise in bioinformatics, plants physiology and molecular biology to unravel the role o arbuscular mycorrhizas in grapevines under abiotic stress. However in 2019 I enrolled as a junior research, through the FCT “Estímulo ao Emprego Ciêntifico” program, at Instituto Superior de Agronomia were I am developing my work regarding grapevine bunch architecture in order to unravel which genetic players are involved in this trait and to develop molecular markers able to identify this trait to be used in plant breeding programs. During this time I was also a lecturer in Cellular biology and Microbiology and Development Biology at the institute which got me in contact with a new and exciting reality of teaching new scientists.
