“…The colonization rate of Scots pine needles by endophytes tends to increase with needle age (Kowalski 1993, Helander et al 1994. A similar colonization pattern has been observed in other Pinus (Hata and Futai 1996, Hata et al 1998, Guo and Wang 2008 and conifer species (Barklund 1987) as well as in deciduous trees (Herre et al 2007, Osono 2008. Hata et al (1998) suggested that the frequency of endophyte of Pinus spp.…”

The seasonal and latitudinal influences on the diversity and abundance of mycota of Pinus sylvestris needles were investigated. A sample of 1620 needles resulted in a total of 3868 fungal isolates, which were assigned to 68 operational taxonomic units (OTUs). The majority of these OTUs (65%) belong to Ascomycota and only 0.03% was grouped as Basidiomycota. The dominant and most frequently isolated OTU was Hormonema dematioides. Other wellknown species with a saprotrophic nutritional mode such as Lophodermium spp. were also observed. The abundance of fungi increased from fall to spring. Frequencies varied significantly in Northern and Southern Finland suggesting that factors associated with latitudinal differences have an impact on the abundance of fungi.

“…La colonizzazione endofitica delle conifere può essere influenzata, non solo dalla morfologia ma anche dall'età dell'ago (Bernstein & Carroll 1977, Carroll & Carroll 1978, Petrini & Carroll 1981, Barklund 1987, Espinosa-Garcia & Langenheim 1990, Stone et al 1994, Stone & Petrini 1997. Ciò è in accordo con quanto da noi riscontrato essendo stato evidenziato un aumento del numero di taxa e della percentuale di aghi colonizzati al progredire dell'età degli aghi sino al 5° -6° anno di vita.…”

Fungal endophytes and epiphytes in needles of Picea abies (L.) Karst. from natural and urban areas in northern Italy.The foliar fungal endophytes community inhabiting needles of Picea abies (Norway spruce) has not been well documented. In this study, carried out in Northern Italy, needles were collected in the years 2003 -2004 in Bagni di Masino and Passo S. Marco (natural locations) and in Milano and Pavia (urban areas). Needles were plated and scored for hyphal outgrowth of endophytes to observe composition and distribution pattern. Both colonization percentage and number of taxa were higher in needles collected in natural locations. There was a large difference in the infection levels between natural and urban areas, portion of the needle (the distal portion showing the largest number of colonies) and among the different needle age classes, with the youngest needles being virtually endophytes free and the 5 and 6 age classes being the most colonized. Thus Norway spruce foliar endophytes population appears to be influenced by age and portion of the needle and location. In the year 2003 fungal epiphytes were also investigated to compare the two different populations. Results analisys show a different distribution of endophytic and ephyphitic taxa, some species being mostly isolated in the natural locations others in the urban ones, thus indicating the presence of different clusters. Zythiostroma pinastri and Tiarosporella parca were the most frequent endophytes in natural locations while Sphaeropsis sapinea was common in urban areas. Among the epiphytes Alternaria alternata, Aureobasidium, and Cladosporium were ubiquitous taxa, Phomopsis was mostly isolated in natural locations.

“…The dominant fungal species are usually presumed to be specific to the host tree species or closely related species (see e.g. Gennaro et al 2003) because each host species usually harbours a characteristic assemblage of endophytic fungi (Barklund 1987;Danti et al 2002;Stone 1987;Toti et al 1992;Viret et al 1994; but see e.g. Suryanarayanan et al 2003).…”
