Haplotype diversity patterns in Quercus suber (Fagaceae) inferred from cpDNA se...
Sousa, Filipe; Viegas, Mariana Bray; Costa, Joana; Marques, Isabel; Pina-Martins; Simões, Fernanda; Matos, José; Glushkova, Maria; Miguel, CéliaChloroplast genome diversity in cork oak (Quercus suber) is characterised by the occurrence of haplotypes that are akin to those found in other Mediterranean oak species, particularly in Q. ilex and Q. rotundifolia, suggesting the possible presence of an introgressed chloroplast lineage. To further investigate this pattern, we reconstructed chloroplast haplotypes by sequencing four chloroplast markers (cpDNA), ...

Sousa, Filipe; Costa, Joana; Ribeiro, Carla; Varandas, Marta; Pina-Martins, Francisco; Simões, Fernanda; Matos, José; Glushkova, Maria; Miguel, CéliaQuercus suber L. is a sclerophyllous tree species native to the western Mediterranean, a region that is considered highly vulnerable to increased temperatures and severe dry conditions due to environmental changes. Understanding the population structure and demographics of Q. suber is essential in order to anticipate whether populations at greater risk and the species as a whole have the genetic background and ...

Small Non-Coding RNAs at the Crossroads of Regulatory Pathways Controlling Soma...
Alves, Ana; Cordeiro, Daniela; Correia, Sandra; Miguel, CéliaSmall non-coding RNAs (sncRNAs) are molecules with important regulatory functions during development and environmental responses across all groups of terrestrial plants. In seed plants, the development of a mature embryo from the zygote follows a synchronized cell division sequence, and growth and differentiation events regulated by highly regulated gene expression. However, given the distinct features of the i...
The metabolic model of the Quercus suber (cork oak tree) leaf
Demirci, H.; Dias, Oscar; Chaves, Inês; Miguel, Célia; Rocha, Miguel; Rocha, I.[Excerpt] The cork oak tree, Quercus suber, is an important renewable resource from which wine stoppers and many other natural products are derived. Portugal is the main producer of cork which approximately manifactures half of the world’s total consumption. The recently sequenced genome of Quercus suber [1] has 953 Mb size containing about 79.000 genes. It is important to have a better under- standing of the g...
Co-exposure to environmental carcinogens in vivo induces neoplasia-related hall...
Martins, Marta; Silva, Ana; Costa, Maria H.; Miguel, Célia; Costa, Pedro M.Addressing the risk of mixed carcinogens in vivo under environmentally-realistic scenarios is still a challenge. Searching for adequate biomarkers of exposure requires understanding molecular pathways and their connection with neoplasia-related benchmark pathologies. Subjecting the zebrafish model to realistic concentrations of two genotoxicants and carcinogens, cadmium and benzo[a]pyrene, isolated and combined...
Chemical characterization and bioactivity of phytochemicals from Iberian endemi...
Gomes, Andreia Karla; Pimpão, Rui; Fortalezas, Sofia; Figueira, Inês; Miguel, Célia; Aguiar, Carlos; Salgueiro, Lígia; Cavaleiro, CarlosAsteraceae family members are well-known for their medicinal potential, comprising several properties that make them unique among plants. Here we focus on Santolina semidentata, an endemic plant from the Iberian Peninsula, not yet described for its medicinal properties. Phytochemical characterization of S. semidentata was performed, concerning total phenol content, flavonoid content, antioxidant capacity, HPLC-...
Identifying signatures of natural selection in cork oak (Quercus suber L.) gene...
Modesto, Inês S.; Miguel, Célia; Pina-Martins, Francisco; Glushkova, Maria; Veloso, Manuela; Paulo, Octávio S.; Batista, DoraCork oak (Quercus suber L.) is an evergreen tree species endemic to the western Mediterranean Basin with a major economical, social and ecological relevance, associated withcorkextractionandexploitation.In the last years,corkoak stands have been facing a significant decline, which may be aggravated by the climate changes that are predicted to occur within cork oak distribution range during this century. Under t...
Valuing the endangered species Antirrhinum lopesianum: neuroprotective activiti...
Gomes, Andreia Karla; Fortalezas, Sofia; Pimpão, Rui; Figueira, Inês; Maroco, João; Aguiar, Carlos; Ferreira, Ricardo B.; Miguel, CéliaPlant phytochemicals are described as possessing considerable neuroprotective properties, due to radical scavenging capacity and acetylcholinesterase inhibitory activity, important bioactivities in neurodegeneration. Antirrhinum lopesianum is a rare endemism from the Iberian Peninsula, occurring at the northeastern border between Portugal and Spain. It is classified as Endangered, due to its highly fragmented g...
