An improved reference genome and first organelle genomes of Quercus suber
Usié, Ana; Serra, Octávio; Barros, Pedro M.; Barbosa, Pedro; Leão, Célia; Capote, Tiago; Almeida, Tânia; Rodrigues, Leandra; Carrasquinho, IsabelCork oak (Quercus suber L.) is an ecologically and economically important evergreen tree species native to the Mediterranean region and widespread in southwest Europe and northwest Africa. An improved genome assembly of cork oak using a combination of Illumina and PacBio sequencing is presented in this study. The assembled genome contains 2351 scaffolds longer than 1000 bp, accounting for 765.7 Mbp of genome si...
Molecular Defense Response of Pine Trees (Pinus spp.) to the Parasitic Nematode...
Modesto, Inês; Mendes, André; Carrasquinho, Isabel; Miguel, Célia M.Pine wilt disease (PWD) is a severe environmental problem in Eastern Asia andWestern Europe, devastating large forest areas and causing significant economic losses. This disease is caused by the pine wood nematode (PWN), Bursaphelenchus xylophilus, a parasitic migratory nematode that infects the stem of conifer trees. Here we review what is currently known about the molecular defense response in pine trees afte...
SNP Detection in Pinus pinaster Transcriptome and Association with Resistance t...
Modesto, Inês; Inácio, Vera; Novikova, Polina; Carrasquinho, Isabel; Van de Peer, Yves; Miguel, Célia M.Pinewood nematode (PWN, Bursaphelenchus xylophilus) is the causal agent of pine wilt disease (PWD), which severely affects Pinus pinaster stands in southwestern Europe. Despite the high susceptibility of P. pinaster, individuals of selected half-sib families have shown genetic variability in survival after PWN inoculation, indicating that breeding for resistance can be a valuable strategy to control PWD. In thi...
Insights into the mechanisms implicated in Pinus pinaster resistance to pinewoo...
Modesto, Inês; Sterck, Lieven; Arbona, Vicent; Gómez-Cadenas, Aurelio; Carrasquinho, Isabel; Van de Peer, Yves; Miguel, Célia M.Pine wilt disease (PWD), caused by the plant–parasitic nematode Bursaphelenchus xylophilus, has become a severe environmental problem in the Iberian Peninsula with devastating effects in Pinus pinaster forests. Despite the high levels of this species’ susceptibility, previous studies reported heritable resistance in P. pinaster trees. Understanding the basis of this resistance can be of extreme relevance for fu...
Primary Metabolite Adjustments Associated With Pinewood Nematode Resistance in ...
Rodrigues, Ana M.; Carrasquinho, Isabel; António, CarlaThe pinewood nematode (PWN) Bursaphelenchus xylophilus is the causal agent of the pine wilt disease (PWD) and represents one of the major threats to conifer forests. The detection of the PWN in Portugal, associated with Pinus pinaster, increased the concern of its spread to European forests. Despite its susceptibility to PWD, genetic variability found among P. pinaster populations has been associated with herit...
Pinus pinaster early hormonal defence responses to pinewood nematode (Bursaphel...
Rodrigues, Ana M.; Langer, Swen; Carrasquinho, Isabel; Bergstrom, Ed; Larson, Tony; Thomas-Oates, Jane; António, CarlaThe pinewood nematode (PWN) is the causal agent of pine wilt disease, a pathology that affects conifer forests, mainly Pinus spp. PWN infection can induce the expression of phytohormonerelated genes; however, changes at the early phytohormone level have not yet been explored. Phytohormones are low-abundance metabolites, and thus, difficult to quantify. Moreover, most methodologies focus mainly on Arabidopsis or...
The draft genome sequence of cork oak
Ramos, António Marcos; Usié, Ana; Barbosa, Pedro; Barros, Pedro M.; Capote, Tiago; Chaves, Inês; Simões, Fernanda; Abreu, Isabl; Carrasquinho, IsabelCork oak (Quercus suber) is native to southwest Europe and northwest Africa where it plays a crucial environmental and economical role. To tackle the cork oak production and industrial challenges, advanced research is imperative but dependent on the availability of a sequenced genome. To address this, we produced the first draft version of the cork oak genome. We followed a de novo assembly strategy based on hi...

Pereira-Leal, José B; Abreu, Isabel A; Alabaça, Cláudia S; Almeida, Maria; Almeida, Paulo; Almeida, Tânia; Amorim, Maria; Araújo, SusanaCork oak (Quercus suber) is one of the rare trees with the ability to produce cork, a material widely used to make wine bottle stoppers, flooring and insulation materials, among many other uses. The molecular mechanisms of cork formation are still poorly understood, in great part due to the difficulty in studying a species with a long life-cycle and for which there is scarce molecular/genomic information. Cork ...
