The corresponding author name has been incorrectly swapped in the original publication. The complete correct name should read as follows. Marta Nunes da Silva In addition, the funding information has been revised. The complete correct funding information is given below. The study was performed within the ‘Characterization of the pinewood nematode/Pinus system: a phytochemical and histopatho-logical approach’ pr...

Resistance of Pinus pinea to Bursaphelenchus xylophilus explained by the dynami...

Knowledge on hormonal and genetic mechanisms of pine trees in response to the pinewood nematode (PWN; Bursaphelenchus xylophilus) is limited. To describe tree defence strategies against B. xylophilus, this study used the plant stress hormone methyl jasmonate (MJ) on four pine species with different susceptibility (Pinus pinaster < P. radiata ≈ P. sylvestris < P. pinea). Three-year-old trees were sprayed with MJ...

Traumatic resin ducts induced by methyl jasmonate in Pinus spp

Key message Exogenous MJ does not alter the resin duct structure of pines in the cortex, but increases the number, density and mean size of resin ducts in the secondary xylem, particularly in Pinus sylvestris and P. radiata. Abstract Methyl jasmonate (MJ) is an organic compound capable of modulating defence responses in plants. Exogenous application of MJ has been shown to modify the structure of the resin cana...

Risk of damage by the pine weevil Hylobius abietis in southern Europe: effects ...

The pine weevil (Hylobius abietis) is one of the most devastating pests of regenerated coniferous forests in northern and central Europe. Although it is also present and potentially harmful in southern Europe, little attention has been paid to this pest in that region. With the aim of quantifying the potential risk of the pine weevil as a forest pest in southern Europe, we performed an intensive assessment of w...

Susceptibility to the pinewood nematode (PWN) of four pine species involved in ...

The pine wilt disease (PWD), caused by the pinewood nematode (PWN) Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle, is one of the most serious threats to pine forests worldwide. Here we studied several components of susceptibility to PWN infection in a model group of pine species widely distributed in Europe (Pinus pinaster Ait., P. pinea L., P. sylvestris L. and P. radiata D. Don), specifically concernin...

Intraspecific variation of anatomical and chemical defensive traits in Maritime...

Key message Migration ability of the PWN through wood branch tissues of adult Maritime pine trees significantly differed among Iberian provenances and this variation was related to differences in anatomical and chemical defensive traits. Abstract The pinewood nematode or pine wilt nematode (PWN; Bursaphelenchus xylophilus) is one of the most dangerous threats to European coniferous forests, especially for the s...

The role of induced defences in Pinus spp. against the pine wood nematode (Burs...

Introduction: The pine wilt disease (PWD) is caused by the nematode Bursaphelenchus xylophilus and affects mainly Pinus pinaster trees, leading to the cut down of thousands of symptomatic and asymptomatic trees every year, imposing great economical and environmental challenges. So far, no effective solution has been developed. Jasmonic acid is a plant hormone involved in various physiological processes such as ...

Teste de susceptibilidade ao nemátode da madeira do pinheiro (bursaphelenchus x...

A doença da murchidão do pinheiro é uma doença grave que afecta florestas de coníferas com uma elevada taxa de mortalidade, sendo causada pelo nemátode Bursaphelenchus xylophilus. Dado que este organismo foi recentemente introduzido na Europa, é importante determinar o grau de susceptibilidade de espécies florestais autóctones ao nemátode. Neste trabalho optimizou-se um teste de susceptibilidade para utilização...
