“…It could also explain its sudden appearance in various chestnut-growing areas of Italy, because probably already present on trees. Nevertheless, this fungus, like S. pseudotuberosa, was not reported in previous investigations on endophytism in chestnut shoots carried out in Switzerland (Bissegger & Sieber 1994). Other fungi belonging to the Gnomoniopsis genus were also described as endophytic on Fagacae (Walker et al 2010).…”

The quality and quantity of nut production are fundamental to the economic viability of chestnut cultivation, yet recent reports indicate that severe damage due to moulds represents a significant problem for growers. We carried out an investigation of the agents of chestnut rot and internal fruit damage in three orchards in Italy. Black and brown rot, as well as insect damage, were found in all the areas examined. Brown rot appeared to be the main cause of damage, affecting 8% to 49% and 2% to 24% of nuts collected from the ground and from burrs, respectively. With respect to morphology and DNA sequencing analyses, fungal isolates obtained from brown rot were homologous with Gnomoniopsis sp. obtained from Dryocosmus kuriphilus (Yasumatsu) galls and with Gnomoniopsis castanea and Gnomoniopsis smithogilvyi described on chestnut in Italy and Australia, respectively. The same fungus was also isolated from the bark of one- and two-years-old healthy shoots at each site, supporting the endophytic behaviour of this rot agent. Brown rot symptoms on nuts associated with Gnomoniopsis sp. corresponded with those previously described by several authors and referred to as Phoma or Phomopsis endogena, suggesting a relationship between these fungi and Gnomoniopsis sp. It is to notice that the escalation of brown rot damage in Italy followed several periods of drought and probably the recent invasion of D. kuriphilus, both stress factors for chestnut trees

The species composition of the endophytic mycobiota in bark, leaves and twigs of Laurus nobilis were studied in Western Anatolia. Four sampling sites were selected; one of which was sampled twice, in spring and autumn. About 3892 fungal isolates obtained grouped into 85 morphological types. The 11 dominant species, with isolation frequencies >1.5%, were Alternaria alternata, Botryosphaeria sarmentorum, Colletotrichum dematium, C. gloeosporioides, Hendersonula sp., Paraconiothyrium sp., Phoma sp., three species of Phomopsis and Seimatosporium lichenicola. Numbers of fungal species isolated per tree differed between the sampled sites. Isolation frequencies of the dominant species, and other less frequent species, were dependent on the sampling site. The degree of endophytic infection and the diversity of fungal species were significantly higher in spring. Frequencies of all dominant species depended significantly on season, except for Stemphylium sp. and S. lichenicola. Analysis of the total endophytic mycoflora of the sampled trees suggested that geographical factors affects the endophytic distribution patterns more significantly than seasonal factors.

“…Another important aspect of the host-pathogen infection processes is that some phytopathogenic fungi could live as endophytes during part of their life cycle (Bisseger and Sieber 1994;Franz et al 1993;Sieber et al 1991b). This is an important factor in plant-microbe interactions.…”

This study investigates the diversity of fungal endophytes associated with several varieties of grapevines with differing modes of cultivation in the Madrid region (central Spain). Our goal is to screen for and identify new fungal biocontrol agents against vine diseases, especially those associated with young plants produced in nurseries. A total of 500 fungal strains representing 68 taxa from six locations were isolated and characterised. Differences regarding cultivar and plant part processed were analysed in terms of composition and relative abundance of species. Some of the more frequently isolated strains represented were Acremonium, Alternaria, Aureobasidium, Botryotinia, Cladosporium, Epicoccum, Fusarium, Gibberella, Nectria, Penicillium, Phoma and Trichoderma species. Botryosphaeria species and Phomopsis viticola were also frequently isolated and may be vine pathogens. Several species of Acremonium, Phoma (P. glomerata) and Chaetomium showed promising antagonistic activity at the laboratory scale.
