Currently, kiwifruit cultivation arouses great economic interest in the agricultural sector in several countries of the European Union due to high consumer demand and good results achieved in terms of production potential and fruit quality. One of the main bacterial species that cause yield losses in kiwifruit plants is Pseudomonas syringae. Diseas...
The aim of this study was to characterise the performance of new molecular methods for the detection and identification of Pseudomonas syringae pv. actinidiae (Psa) and to provide validation data in comparison to the assays mentioned in official diagnostic protocols and being currently used. Eleven molecular tests for the Psa detection were compare...
The reproductive strategy of the pinewood nematode (PWN), Bursaphelenchus xylophilus, is sexual amphimictic and oviparous. The incidence of intrauterine egg development and hatching in plant-parasitic nematodes is not a very common phenomenon. During the process of maintaining and breeding a B. xylophilus population isolated in Spain under laborato...
Pinewood nematode (PWN), Bursaphelenchus
xylophilus, the causal agent of pine wilt disease (PWD),
was detected in Spain in 2008. This gives rise to serious
concern, as the disease has caused severe environmental
and economic losses in Portugal and in Asian countries.
We studied interspecific variation in susceptibility to pine
wilt disease and diff...
The disease huanglongbing (HLB), caused by the phloem-limited and psyllid-vectored 'Candidatus Li-beribacter' spp., is threatening the Mediterranean citrus industry. The African psyllid (Trioza erytreae) vector of the pathogen was detected in Madeira (Portugal) in 1994 and in the Canary Islands (Spain) in 2002, and its arrival in 2014 in northwest...
Pseudomonas syringae pv. actinidiae (Psa) is the causal agent of bacterial canker of kiwifruit, the most severe disease of this culture at the moment, causing significant economic losses in the main kiwi producing countries. The most characteristic symptoms are leaves with small dark-brown necrotic spots surrounded by a yellow halo and red-rusty ex...
Pseudomonas syringae pv. actinidiae (Psa) es la responsable del chancro bacteriano del kiwi, una enfermedad que se ha extendido rápidamente en los principales países productores causando importantes pérdidas económicas. Para intentar frenar la dispersión del patógeno y controlar el desarrollo de esta enfermedad, es necesario utilizar técnicas de di...
we study if different treatments can induce defensive responses in pine seedlings with the objective of detecting the chemical compounds that could be involved in the resistance to this disease.

As a consequence of the report of pine wood nematode (Bursaphelenchus xylophilus) in the Setúbal peninsula (Portugal), nematodes of the genus Bursaphelenchus and the vector insect were studied in pine forests, timber industries and entry points for imported timber in Galicia (north-west Spain). The aim of this paper was to contribute to the establi...
Title: Plant pathogenic nematodes associated with genus Camellia in Galician public gardens. At present, the studies on plant-parasitic nematodes associated with genus Camellia are scarce. As this ornamental plant is abundant in Galicia, during year 2003, a nematodes sampling was performed in several Galician public parks and gardens with camellias...

... DNA was extracted from cells pellet using E.Z.N.A.1 Bacterial DNA purification Kit (Omega Biotek, USA) following the manufacturer's instructions. For molecular identification of the 22 isolates, a duplex-Polymerase Chain Reaction (PCR) was performed as recommended by EPPO guideline [47] and recently demonstrated by Loreti et al. [48] as a powerful method for Psa identification. The primers used for identification are in the S2 Table: the primers KN-F/KN-R [49] and AvrDdpx-F [50] are specific for omp1 (outer membrane protein 1) and avrD1 (Effector) genes, respectively. ...

... So far, the presence of PWN has not been confirmed in forests outside of Portugal and Spain, but an introduction into new areas is likely due to the increasing trade in timber and various woodrelated commodities. In Central Europe, such a scenario could have devastating consequences considering that Scots pine (Pinus sylvestris L.) is one of the most important (economically and environmentally) tree species, but also most susceptible to PWN infestation (Evans et al. 1996, Menéndez-Gutiérrez et al. 2018). Currently, the risk of PWN establishment in Central Europe is favoured by observed climatic changes. ...

... These results support the interest in quantifying these phenotypic traits to characterize possible more virulent strains in Psa biovar 3. Bacterial motility, associated with high secretion of biofilm components, Conventional genetic approaches to the Psa3 population in Europe supported in the last decade a clonal community as proposed by Firrao et al. [44]. Also, after the first report of Psa3 in Portugal in 2010 by Balestra et al, [15], other authors supported a highly conserved population structure of Psa3 [18,45]. Ciarroni et al, [46] identified a different pattern through fragment analysis among two Psa strains from Portuguese orchards. ...

... Strengths It is significant to highlight that there have been no reports of PSA bacterium and kiwi decline in A. arguta, unlike in A. deliciosa[4,10,55]. The answers from the stakeholders also show constant yields per hectare with A. arguta compared to consistent fluctuations in the production of A. deliciosa over the past 10 years. ...
... Liberibacter africanus" (CLaf), of which Trioza erytreae is associated with CLaf (Bové, 2006). This disease has not yet been detected in mainland Europe (Cocuzza et al., 2017;Pérez-Otero et al., 2015;Siverio et al., 2017) but the triozid vector was identified in Galicia (northwest of the Iberian Peninsula) in 2014. Since then, T. erytreae has spread along the coasts of Portugal and north of Spain and is the main threat to the Mediterranean citrus industry. ...

... The nematode was first detected in Europe in Setubal (Portugal) in 1999 (Mota et al. 1999, Dwinell 1997, and given the importance for pine forests and the timber industry, several surveys have been carried out throughout Europe (McNamara 2004, Braasch et al. 2004), including Poland (Kamkowski 2008, Greece (Michalopoulos et al. 2004), Switzerland (Polomski et al. 2005), Norway (Magnusson et al. 2004), Russia (Kulinich 2004) and Spain (Escuer et al. 2004, Abelleira et al. 2003. ...

... Thereafter, it spread to China and Korea in the 1980s (Cheng et al. 1986;Yi et al. 1989), and in the late 1990s it was introduced to Europe ( Mota et al. 1999). In this new century, it continues to spread to new areas (Robertson et al. 2011;Fonseca et al. 2012), even to cold regions at high latitudes (Zhao et al. 2017). Yet, more than a century after its epiphytotic, there has been little success in developing economical and effective control strategies for this devastating disease. ...
