Unusual Nevertheless Doable Daporinad Methods
9?��?0.2 species per plant, compared with 6.4?��?0.5 in roots. Endophyte diversity followed a very similar pattern to species richness (Fig.?1b), despite the identity of the species constituting the fungal communities differing from plant to plant and season to season (Table?1). Calculation of Jaccard indices added further evidence for the lack of similarity between fungal species community

composition in plant organs and host species. At the individual plant level, when all fungal species from the leaves and all those isolated from the roots of each individual were compared, there was an extremely low similarity between the communities in roots and Selleckchem INCB018424 shoots (Table?2). Pairwise comparisons of endophyte species from each of the three host plants (Table?3) demonstrated an equally low similarity in fungal species composition of the three plant species. The few fungi that were common to two or all three plant hosts�� root systems were C.?rosea, C.?destructans,

T.?koningii and Arthrinium arundinis (Corda) Dyko & B. Sutton (with A.?alternata replacing A.?arundinis as a shared species in June). Above-ground, shared fungal species only occurred in June; these were Cladosporium cladosporioides (Fresen.) G.A. de Vries, C.?oxysporum, A.?alternata and a yellow yeast. Non-metric multidimensional scaling produced a clear separation of the fungal communities (Fig.?2). Here, it can be seen that axis 1 appears to depict a separation of time, whilst axis two represents plant part. This analysis reinforces the fact that some communities showed relatively little change over time (e.g. roots of R.?acetosa),

whilst others showed dramatic changes (e.g. leaves of R.?acetosa). Mycorrhizal colonization was absent in R.?acetosa on both sampling dates. Colonization differed between the other two plant species (F1,36?=?25.1, P?
