Abstract
The result showed that 52 fragments (64.22%) were polymorphic bands from seven combinations of Sequence-Related Amplified Polymorphism (SRAP) markers. The genetic relationship was analyzed using the UPGMA method by NTSYpc software version 2.11X showed a similarity coefficient ranging from 0.59 to 0.98. Endophytic fungi were isolated from fresh leaves of Yellow Star (Schoutenia glomerata King subsp. peregrina (Craib) Roekm. & Hartono and identified by morphology and DNA barcoding. The fungi were identified in Alternaria alternata, Colletotrichum siamense, Diaporthe arengae, Phyllosticta capitalensis, and Xylaria cubensis. The dual culture test evaluated the efficacy of endophytic fungi isolated from Yellow Star tree against Colletotrichum gloeosporioides and Phomopsis asparagi causing disease in asparagus. The results revealed that X. cubensis had the potential to inhibit the spore germination of the C. gloeosporioides ASGC06 and P. asparagi ASGP04, which inhibited spore germination of 99.97 and 100 percent, respectively. However, this fungus should be further studied for biological control and bioactive secondary metabolites.
