Root associated Fusarium solani Species Complex (FSSC) in epiphytic and terrestrial orchids

Abstract. Sukarno N, Mursidawati S, Listiyowati Nugraha NH, Fadillah WN, Waite M. 2023. Root associated Fusarium solani Species Complex (FSSC) in epiphytic and terrestrial orchids. Biodiversitas 24: 2577-2586. Members of the are ecologically diverse, covering human plant pathogens, saprobes, endophytic fungi economically important plants. The role FSSC on tropical orchids, however, has received little attention. This research aimed to isolate identify found as endophytes roots orchids Cymbidium finlaysonianum Lindl. Vanda tricolor Lindl., Calanthe triplicata (Willemet) Ames Phaius tankervilleae (Banks) Blume. Fungal isolation was obtained from peloton structures within root. identification done using combined morphological molecular characteristics ITS rDNA sequences. Four isolates were identified based characteristics. BLAST analysis showed that all (FSSC). Further phylogenetic relationship indicated belonged FSSC5 lineage or sensu stricto, which is nested clade 3 a subgroup. F. stricto V2 CF34 isolated C5 P44 It interesting form different groups than those first report showing host this broadens known range ecological behavior FSSC5.
