Summary A large database of invasive forest pathogens ( IFP s) was developed to investigate the patterns and determinants invasion in Europe. Detailed taxonomic biological information on species combined with country‐specific data land use, climate, time since identify invasiveness, differentiate class environments which share territorial climate features associated a susceptibility invasion. s increased exponentially last four decades. Until 1919, already present moved across Then, new were...
Summary An analysis of incidence Phytophthora spp. in 732 European nurseries producing forest transplants, larger specimen trees, landscape plants and ornamentals, plus 2525 areas which trees shrubs were planted, is presented based on work conducted by 38 research groups 23 countries between 1972 2013. Forty‐nine taxa recorded 670 (91.5%); within these nurseries, 1614 1992 nursery stands (81.0%) infested, although most affected appeared healthy. In plantings, 56 recovered from 1667 tested...
Fusarium circinatum, the causal agent of pine pitch canker (PPC), is currently one most important threats Pinus spp. globally. This pathogen known in many pine-growing regions, including natural and planted forests, can affect all life stages trees, from emerging seedlings to mature trees. Despite importance PPC, global distribution F. circinatum poorly documented, this problem also true hosts within countries that are affected. The aim study was review with a particular focus on Europe. We...
Summary This review comprises both well‐known and recently described P hytophthora species concentrates on –woody plant interactions. First, comprehensive data infection strategies are presented which were the basis for three models that explain invasion spread of Phytophthora pathogens in different woody host plants. The first model describes roots, second trunk, last one summarizes plants via leaves. On morphological, physiological, biochemical molecular data, scenarios suggested sequences...
Abstract Key message The effects of MJ on pine trees are species-specific and trigger a resistant phenotype to the PWN. A more dynamic response hormones gene expression in Pinus pinea explains high resistance Bursaphelenchus xylophilus this species. Knowledge hormonal genetic mechanisms pinewood nematode (PWN; ) is limited. To describe tree defence strategies against B. , study used plant stress hormone methyl jasmonate (MJ) four species with different susceptibility ( pinaster < P....
Conifers exhibit a number of chemical and anatomical mechanisms to defend against pests pathogens. Theory predicts an increased investment in plant defences under limited nutrient availability, but while this has been demonstrated for defences, it rarely shown defensive structures. In long-lived woody plant, we tested the hypothesis that availability may promote improved differentiation persistent defences. We also hypothesized costs those long-term structures be determined by genetic...
Pines are major components of native forests and plantations in Europe, where they have both economic significance an important ecological role. Diseases pines mainly caused by fungal oomycete pathogens, can significantly reduce the survival, vigor, yield individual trees entire stands or plantations. Pine pitch canker (PPC), Fusarium circinatum (Nirenberg O’Donnell), is among most devastating pine diseases world, example emergent invasive disease Europe. The effects microbial interactions...
Climate change and pathogen outbreaks are the two major causes of decline in Mediterranean holm oak trees (Quercus ilex L. subsp. ballota (Desf.) Samp.). Crown-level changes response to these stressful conditions have been widely documented but responses root systems remain unexplored. The effects environmental stress over roots its potential role during declining process need be evaluated. We aimed study how key morphological architectural parameters nonstructural carbohydrates affected...
The pine wilt disease (PWD), caused by the pinewood nematode (PWN) Bursaphelenchus xylophilus (Steiner et Buhrer) Nickle, is one of most serious threats to forests worldwide. Here we studied several components susceptibility PWN infection in a model group species widely distributed Europe (Pinus pinaster Ait., P. pinea L., sylvestris L. and radiata D. Don), specifically concerning anatomical chemical traits putatively related resistance, whole-plant population after experimental inoculation,...
Fusarium circinatum is a highly virulent invasive pathogen that causes the disease commonly known as pine pitch canker ( PPC ). On mature trees, most common symptoms of include resin bleeding, resinous cankers, wilting needles and dieback. In nurseries main are yellowish needles, foliage shoots. considered one important diseases conifers globally at least 60 species Pinus along with Pseudotsuga menziesii to be susceptible. Quarantine regulations crucial minimize risk new introductions into...
The resistance to abiotic stress is increasingly recognised as being impacted by maternal effects, given that environmental conditions experienced parent (mother) trees affect tolerance in offspring. We hypothesised effects may also mediate the of biotic stress. influence environment and genotype interaction these two factors on early Pinus pinaster half-sibs Fusarium circinatum pathogen was studied using 10 mother genotypes clonally replicated contrasting environments. Necrosis length...
The Spanish elm programme began in 1986 response to the devastating impact of Dutch disease on natural stands and urban trees. Its main objectives were conserve remaining genetic resources select breed tolerant native genotypes. After 27 years work conducting susceptibility trials thousands genotypes, first seven Ulmus minor trees are now being registered by Environmental Administration. This paper presents results tests these clones their distinctive genetic, morphological phenological...
Forests in Europe are threatened by increased diversity of Phytophthora species, but effects on trees simultaneous infections and ecological consequences their coexistence unknown. This study explored variation early survival Quercus ilex to assessed interactions between species when were co‐infected. Three ( P. cinnamomi , gonapodyides quercina ), seeds from 16 populations Q. ballota subspecies) two infection times used as sources experiments. The influence subspecies plant germination...
Increasing drought conditions in Mediterranean countries are negatively impacting the survival and productivity of Castanea sativa Mill. The study aimed to select EST-SSR markers associated with stress developed Quercus spp. evaluate their transferability polymorphism C. sativa. Eight were selected examine adaptive potential four wild populations relation tolerance. To validate markers, offspring trees water stressed tolerance was assessed. leaf wilting seedlings after treatment revealed a...
