PratyOmics - Metabolómica da planta para o controlo do nemátode das lesões radi...
Barbosa, Pedro; Costa, Marina; Espada, Margarida; Teixeira, Dora; Brás, Teresa; Duarte, Fátima; Figueiredo, Joana; Cardoso, Joana; Esteves, IvâniaO nemátode-das-lesões-radiculares (NLR), Pratylenchus penetrans, é um endoparasita migratório que afeta culturas agrícolas economicamente importantes, como a batata, estando atualmente presente na lista de pragas reguladas não sujeitas a quarentena A2 da União Europeia (UE 2016/2031). Em alguns países europeus, como Portugal, esta espécie foi detetada em campos de produção de batata estando relacionada com o se...
O uso da biotecnologia no estudo de doenças da floresta
Faria, Jorge M. S.; Santos, Margarida T.; Nóbrega, Filomena; Espada, Margarida; Inácio, Maria LurdesA biotecnologia vegetal permite a criação de ferramentas laboratoriais para agilizar a investigação em doenças da floresta. As culturas in vitro de rebentos de pinheiro são usadas no estudo bioquímico da doença da murchidão do pinheiro, causada pelo nemátode da madeira do pinheiro.
Os nemátodes como bioindicadores do status do solo: o projeto MaisSolo
Inácio, Maria Lurdes; Camacho, Maria João; Rusinque, Leidy; Nóbrega, Filomena; Matos, Susete; Almeida, Maria Lurdes; Nunes, Ana PaulaOs sistemas de produção intensivos hortoindustrais do Ribatejo (centro de Portugal) baseiam-se no recurso à monocultura e num elevado grau de intervenções culturais. O projeto MaisSolo, um consórcio formado por agricultores, associações de produtores, investigadores e a academia, teve por objetivo demonstrar que a introdução de culturas de cobertura contribui para a melhoria da estrutura do solo e da sua capaci...
Root-knot nematode assessment: species identification, distribution, and new ho...
Rusinque, Leidy; Camacho, Maria João; Serra, Clara; Nóbrega, Filomena; Inácio, Maria L.Considered one of the most devastating plant parasitic nematodes worldwide, Meloidogyne spp. (commonly known as the root-knot nematodes (RKNs)) are obligate sedentary endoparasites that establish in the roots, causing hyperplasia and hypertrophy of surrounding cells, triggering the formation of galls. These galls will affect root development and physiology, leading to substantial yield losses. During 2017-2022,...
How parasitism genes are regulated: a motif to search for genes regulators in t...
Mendonça, Madalena; Vicente, Cláudia S. L.; Barbosa, Pedro; Velada, Isabel; Vieira, Paulo; Faria, Jorge; Santos, Margarida; Nóbrega, FilomenaPlant-parasitic nematodes threaten global agricultural and forestry systems. The search for new control strategies in line with the EU’s sustainability goals highlight significant knowledge gaps. Like all other plant pathogens, plant-parasitic nematodes deliver several parasitism proteins (effectors) into the host plant to cause disease. NemaWAARS project focuses on mechanism(s) of regulation and gene control e...
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...
Nematode-Mycobiota interactions in Pine Wilt Disease
Vicente, Cláudia; Faria, Jorge; Espada, Margarida; Nóbrega, Filomena; Bonifácio, Luís; Bragança, Helena; Sousa, Edmundo; Inácio, MLPine wilt disease is one of the most important diseases for conifer forests worldwide. This complex disease involves the interaction between three primary biological elements - the plant parasitic nematode Bursaphelenchus xylophilus; the insect-vector Monochamus sp., and the host tree Pinus spp. – and other secondary elements such as endophytic bacteria and fungi. The development of B. xylophilus is strongly as...
Fungal Communities of the Pine Wilt Disease Complex: Studying the Interaction o...
Vicente, Cláudia S.L.; Soares, Miguel; Faria, Jorge M.S.; Espada, Margarida; Mota, Manuel; Nóbrega, Filomena; Ramos, Ana Paula; Inácio, Maria L.Considered one of the most devastating plant–parasitic nematodes worldwide, Bursaphelenchus xylophilus (commonly known as pinewood nematode, PWN) is the causal agent of the pine wilt disease in the Eurasian coniferous forests. This migratory parasitic nematode is carried by an insect vector (Monochamus spp.) into the host tree (Pinus species), where it can feed on parenchymal cells and reproduce massively, resu...
Root-Knot Nematode Species Associated with Horticultural Crops in the Island of...
Rusinque, Leidy; Nóbrega, Filomena; Cordeiro, Laura; Lima, Arlindo; Andrade, Samuel; Inácio, Maria LurdesPlant-parasitic nematodes (PPN) are an economically important group of plant pests present throughout the world. In particular, root-knot nematodes (RKN), sedentary endoparasites of a wide variety of economically important hosts with the ability to survive in temperate regions. During 2020–2021 an extensive survey of Meloidogyne spp. was undertaken on the island of São Miguel Azores, Portugal. A total of 80 sam...
First report of Pratylenchus penetrans (Nematoda: Pratylenchidae) associated wi...
Runsique, Leidy; Vicente, Claudia Sofia; Inácio, Maria de Lurdes; Nóbrega, Filomena; Camacho, Maria João; Lima, A; Ramos, Ana PaulaThe world flower business is a highly dynamic industry and in Portugal yields around EUR 500 million a year (INE 2013). Root lesion nematodes (RLNs), Pratylenchus spp., are considered the third most important group of plant parasitic nematodes (PPNs) worldwide due to their large distribution, wide host range, and impact on economically important crops (Castillo and Vovlas 2007). The most recent report of RLNs p...
