The root lesion nematode effector Ppen10370 is essential for parasitism of Prat...
Vieira, Paulo; Vicente, Claudia; Branco, Jordana; Buchan, Gary; Mota, Manuel; Nemchinov, LevThe root lesion nematode, Pratylenchus penetrans, is a migratory species that attacks a broad range of crops. Like other plant pathogens, P. penetrans deploys a battery of secreted protein effectors to manipulate plant hosts and induce disease. Although several candidate effectors of P. penetrans have been identified, detailed mechanisms of their functions and particularly their host targets remain largely unex...
Combining metagenomics with morphology-based approaches to understand microbiom...
Vieira, Soraia; Sroczynska, Katarzyna; Martins, Marta; Costa, M.H.; Neves, Joana; Adão, Helena; Vicente, ClaudiaSediment microbiome has an essential role in regulating ecosystem functions, not only regulating primary productivity and nutrient cycling but also shaping trophic interactions with higher trophic levels. While the importance of microbiome in terrestrial soil systems is highly recognized, its role in marine aquatic environments remains much less studied. Microbiome can be highly affected by bottom up (abiotic f...
Biological interactions between nematophagous fungi, Esteya spp., and the pinew...
Pires, David; Vicente, Claudia; Inacio, ML; Mota, ManuelThe pinewood nematode (PWN), Bursaphelenchus xylophilus, is a quarantine organism in several countries and the causal agent of pine wilt disease (PWD), a serious threat to pine forests worldwide. PWD results from complex interactions between the nematode, its insect vector, Monochamus spp., and host plants (conifers), being the nematode the common element in this interaction. The PWN is considered the sixth mos...
Plant Metabolomics for the control of the root-lesion nematode Pratylenchus pen...
Vicente, Claudia; Faria, Jorge; Teixeira, Dora; Vieira, Paulo; Espada, Margarida; Barbosa, Pedro; Figueiredo, Joana; Cardoso, Joana; Esteves, IvaniaPratylenchus penetrans, one of the most detrimental root-lesion nematode species, greatly reduces the production in numerous important agronomic crops (e.g., corn, potato), ornamental plants (e.g., lily, roses) and fruit trees (e.g., almond, cherry orchards). In the EU, P. penetrans has been reported as the most damaging species associated with potato (Solanum tuberosum L.). In Portugal, this species was also d...
Nemátode-dos-citrinos: prevenir o declínio lento do pomar
Inácio, Maria de Lurdes; Rusinque, Leidy; Vicente, Claudia; Camacho, Maria JoãoOs citrinos são as fruteiras mais importantes em termos de produção a nível mundial, com cerca de 130 milhões de toneladas produzidas (World Citrus Organisation, 2020), repartin- do-se por mais de 125 países localizados entre os 40° de latitude a norte e a sul do Equador. Entre as várias ameaças à produção citrícola contam-se os nemátodes fitoparasitas. Os nemátodes fitoparasitas são pequenos animais, de aspeto...
Potato Cyst Nematodes: geographical distribution, phylogenetic relationships an...
Camacho, Maria João; Andrade, Eugénia; Mota, Manuel; Nobrega, Filomena; Vicente, Claudia; Rusinque, Leidy; Inácio, Maria LurdesThe identification and phylogenetic relationships of potato cyst nematodes (PCN) were studied to assess the potential value of geographical distribution information for integrated pest management of potato production in Portugal. This research focused on PCN species, Globodera pallida and Globodera rostochiensis. From 2013 until 2019, 748 soil samples from the rhizosphere of different potato cultivars were surv...
NEMÁTODES DE QUISTO DA BATATEIRA – O USO DE VARIEDADES RESISTENTES COMO ESTRATÉ...
Camacho, Maria João; Andrade, Eugénia; Rusinque, Leidy; Vicente, Claudia; Inácio, Maria de LurdesPotato cyst nematodes (PCN), Globodera rostochiensis and G. pallida, are considered harmful quarantine organisms and can be devastating to potato fields if not controlled in a timely manner. Its designation derives from the fact that the female body, after their death, turns into a spherical cyst con- taining the eggs, which are protected from adverse conditions even in the absence of hosts. PCN are present in ...
Mycobiota of Pinus pinaster associated with Pine Wilt Disease
Vicente, Claudia; Bragança, Helena; Bonifácio, Luis; Sousa, Edmundo; Espada, Margarida; Mota, Manuel; Nóbrega, Filomena; Inácio, Maria de LurdesPine wilt disease (PWD), one of the most threatening diseases to coniferous forests worldwide, results from the complex interaction between the causal agent, the pinewood nematode (PWN) Bursaphelenchus xylophilus, the insect-vector belonging to the genus Monochamus and the Pinus spp. tree host. In the later stages of PWD, PWN undertakes an obligatory mycetophagous phase, feeding on the fungi that colonize the d...
Understanding the role and delivery of Pratylenchus penetrans effectors proteins
Vicente, Claudia; Espada, Margarida; Mota, Manuel; Vieira, PauloConsidered one of the most damaging species of root lesion nematodes (RLN), the plant parasitic nematode (PPN) Pratylenchus penetrans is a serious issue worldwide in crop protection and productivity of important agronomic and horticultural crops (e.g. potato, corn). As other PPN, P. penetrans secrete a repertoire of effectors, which once delivered either in the apoplast or inside cells, can trigger and manipula...
PineEnemy - Exploring the NEmatode-MYcobiota interactions in Pine Wilt Disease
Vicente, Claudia; Bragança, Helena; Sousa, Edmundo; Naves, Pedro; Mota, Manuel; Nóbrega, Filomena; Inácio, Maria de LurdesPine wilt disease (PWD) is one of the most important threats to conifer forests in Europe [1] and worldwide [2], causing severe economic and environmental damages. This complex disease results from the interaction between three biological elements: the pathogenic agent Bursaphelenchus xylophilus, also known as pinewood nematode (PWN); the insect-vector (cerambycid beetles of the genus Monochamus) [3], and the h...
