Comparison of genotypic diversity in native and introduced populations of Sphaeropsis sapinea isolated from Pinus radiata
Sphaeropsis sapinea is an endophyte and latent pathogen of pines, assumedly introduced to the Southern Hemisphere along with its host. There are at least three recognised forms of S. sapinea that differ from each other morphologically and can also be separated based on molecular characteristics. Pinus radiata is a native to California but has been used extensively for afforestation in the South...
متن کاملPredicting Sphaeropsis sapinea Damage in Pinus radiata Canopies Using Spectral Indices and Spectral Mixture Analysis
Maintaining the health and condition of the forest plantation estate is critical to ensuring there are no adverse losses in productivity. Within Australian Pinus radiata plantations a diverse range of damaging agents are present. One significant agent is a fungal pathogen Sphaeropsis sapinea. In this research, we detail the development of relationships between a range of individual crown health...
متن کاملSimple sequence repeat markers distinguish among morphotypes of Sphaeropsis sapinea.
Sphaeropsis sapinea is a fungal endophyte of Pinus spp. that can cause disease following predisposition of trees by biotic or abiotic stresses. Four morphotypes of S. sapinea have been described from within the natural range of the fungus, while only one morphotype has been identified on exotic pines in the Southern Hemisphere. The aim of this study was to develop robust polymorphic markers tha...
متن کاملIps pini (Curculionidae: Scolytinae) is a vector of the fungal pathogen, Sphaeropsis sapinea (Coelomycetes), to Austrian pines, Pinus nigra (Pinaceae).
Sphaeropsis sapinea (Fr.:Fr.) Dyko and Sutton, is among the most common and widely distributed pathogens of conifers worldwide. S. sapinea is disseminated over short distances by rain splash and moist wind, but significant knowledge gaps regarding long-range dispersal remain. Our objective was to determine whether or not the pine engraver beetle, Ips pini Say, is a vector of the pathogen onto A...
متن کاملMultiple gene genealogies and microsatellite markers reflect relationships between morphotypes of Sphaeropsis sapinea and distinguish a new species of Diplodia.
Sphaeropsis sapinea is an opportunistic pathogen causing serious damage to conifers, pre-disposed by adverse environmental conditions or mechanical damage. Three different morphological forms of the fungus have been described and are commonly referred to as the A, B and C morphotypes. Isolates of the different morphotypes have also been separated based on differences in pathogenicity and molecu...
