Phosphate Solubilizing and Antifungal Activity of Root Endophyte Isolated from Shorea leprosula Miq. And Shoreal selanica (DC) Blume.

Abstract

Fungal endophytes are fungi that lives within plant tissues without causing apparent disease. It is also suggested that these fungi have ability to enhance plant growth and plant resistancy against pest and disease. This research is a preliminary study about root fungal endophytes in dipterocarp since there are lack research concerning about this study focus. We examined root fungal endophyte isolated from seedling of Shorea leprosula and Shorea selanica taken from Dramaga Experimental Forest, Bogor. Furthermore, we also tried to find out the fungal potential ability to solubilize phosphate and suppres fungal pathogen by in vitro assay. Surface sterilization method was used to isolated fungal endophytes from root tissues. Trichoderma spirale, Velsalceae sp., Melanconiela ellisii, Chaetosphaeria callimorpha, and Trichoderma asperellum were isolated during this study. These fungi appear to have specific association between fungal species and host plant, but no evidence of fungal order-level specificiation in S. leprosula and S. selanica. In vitro test also suggested that root fungal endophyte Trichoderma spirale and Melanconiella elisii have potential ability to solubilize inorganic phosphate. In addition, this result also present that root fungal endophyte T. spirale and T. asperellum have the potential to inhibit pathogen fungi Fusarium sp.

Use of different Trichoderma species in cherry type tomatoes (Solanum lycopersicun L.) Against Fusarium oxysporum wilt in tropical greenhouses

“…The use of T. spirale as biological control agent is uncommon and few reports on its biological characterization are available in the literature. Hakim et al (2015) proved a high antifungal index against Fusarium, endophytic behavior and phosphate solubilizing effect of a T. spirale strain from Indonesia but in in vitro conditions. Conversely to the results, T. spirale had low effect controlling F. oxisporum in eggplants under fields conditions comparted to T. hamatum and T. virens (Abdel-Monaim et al 2014).…”

The Use of Fungal Endophyte Penicillium citrinum on Tree Seedling: Applicability and Limitation

“…Many fungi identified as endophytic fungi, including Penicillium citrinum. During this research, P. citrinum show the ability to improve the growth of the plant [13]. P. citrinum produced hormone Indole Acetic Acid (IAA), extracellu lar en zy mes, and au xin which can increase the growth of the inoculated plants [14].…”

Endophytic fungi and their potential in controlling white root disease of cashew

“…Several previous studies had also proven that endophytic fungi could solubilize phosphate. Hakim et al (2012) reported that the endophytic fungus Trichoderma spirale isolated from roots could solubilize phosphate in vitro. Priyadharsini and Muthukumar (2017) also reported that the endophytic fungus Curvularia geniculate from the roots of Parthenium hysterophorus could increase plant growth through phosphate solubilization.…”
