| Summary: | Dipterocarpaceae is known as the dominant forest vegetation family in tropical forests that has mutual symbiosis with ectomycorrhizal fungi. It makes tropical forest resilience depend on the existence of ectomycorrhizal fungi. The role of ectomycorrhizal fungi to support the regeneration was found in multi-host form, indicated by sharing ectomycorrhizal fungal species between plants. Based on that phenomenon, the study aims to recognize ectomycorrhizal fungi that associate with dipterocarpaceae at tree and seedling levels, and the presence of multi-host ectomycorrhizal fungi on both growth stages. The research was conducted by identifying the ectomycorrhizal fungi via molecular approach by using Polymerase Chain Reaction (PCR) technique. To strengthen the sequence of DNA extracts, a specific primer pair of ITS 1F-ITS 4 was used. The identity of the ectomycorrhizal fungi was obtained by matching the samples’DNA sequence to the Genbank database. Based on the identification results, ectomycorrhizal fungi that associate with dipterocarpaceae on tree and seedling levels have genetic relationship with Dothideomycetes class and Sordariales, Sebacinales, Cantharellales, Russulales, Agaricales, Boletales, and Thelephorales orders. The research also found that multi-host of ectomycorrhizal fungi to dipterocarpaceae is formed both in different species and growth stages of host (tree and seedling). The most ectomycorrhizal fungi that play a role in multi-host are those with genetic relationship to the orders of Thelephorales, Russulales, and Sebacinales. Tomentella sp. of Thelephorales order was the most multi-host on both tree and seedling levels. R. lepidicolor, Sebacina sp., and ectomycorrhizal fungi of Thelephoraceae were found multi-host in seedling level. The existence of ectomycorrhizal fungi associated in multi-host with dipterocarpaceae is a natural asset for rehabilitation effort of degraded tropical forests. |
