Importance of ectomycorrhizal association in conservation of Himalayan Oaks.

Most conservation efforts in dry tropical forests have overlooked less obvious targets for conservation, such as mycorrhizal fungi, that are critical to plant growth and ecosystem structure. However, community structure of fungal fruiting bodies and ectomycorrhiza associated with Oaks was poorly studied not only in Pakistan but also in Asia in comparison to other parts of world. So, above ground ectomycorrhizal fungal communities partners in form of fruiting bodies as well as below ground ectomycorrhizal fungal communities partners in form of morphotypes were collected from seven different oak forests of Swat and Dir, KP, Pakistan. This investigation, based on morpho-anatomocal as well as phylogenetic analysis, revealed a high diversity of 256 fungal taxa. From above ground, 53 species were identified as ectomycorrhizal fruiting bodies belonging to 24 genera and 15 families. At family level, Russulaceae (3 Lactarius spp., 8 Russula spp.) was the most diverse following by Boletaceae (8 genera; 9 species), Amanitaceae (7 Amanita spp.), Inocybaceae (7 Inocybe spp.) and Sclerodermataceae (6 Scleroderma spp.). From below ground, 168 taxa were identified belonging to 33 genera and 25 families, grouped into 25 ECM lineages. The /russula-lactarius was most diverse lineages with 39 OTUs followed by /tomentella-thelephora (22 OTUs). These findings exhibit most diverse and rich ectomycorrhizal communities associated with oaks. The oaks of Pakistan are hotspot for their ECM mycobionts and they have the largest number of potential endemic species. Information collected from this study can be used as baseline information for future studies to investigate the impacts of different ectomycorrhizal fungi on endemic oak.
