“…The fact is that fatty acid profi les may also be useful for identifi cation and characterization of fungi (Muller et al 1994;Stahl and Klug 1996;Pankhurst et al 2001;Ruess et al 2002). Moreover, recent work has shown that variation in the relative concentration of the fatty acids is sufficient to enable effective differentiation for subspecifi c groups of Penicillium (Lopes da Silva et al 1998), Rhizoctonia (Matsumoto et al 1997;Stevens and Jones 2001;Matsumoto 2005), Pythium (Pankhurst et al 2001), Phytophthora (Larkin and Groves 2003), and Fusarium (Matsumoto 2006).…”

Endophytic fungi live in healthy tissues of many plants, including in medicinal plant such as Asiatic pennywort (Centella asiatica). These fungi exist in different parts of the plant as symbionts. The study aimed to isolate endophytic fungi from various parts of Asiatic pennywort of Malaysia accession and characterize their nature. Three individual plants of Asiatic pennywort (3 months-old) were obtained from the Sringanis Medicinal Garden in Bogor. The endophytes were isolated on Malt Extract Agar. The community structures of the endophytes were analyzed based on their diversity, colonization, dominance index, and relative frequency of occurrence of the isolated endophytic fungi. A total of 78 isolates have been obtained from three individual plants and clustered into 22 morphotypes consisted of 18 morphotypes of Ascomycota and 4 morphotypes of Basidiomycota divisions. The stolons harbored more endophytes (22.9 %) followed by leaf (16.7 %), root (11.8 %), and petiole (7.6 %). The diversity index was classified as medium category with the highest result (1.91) was found in the root, followed by leaf (1.79), stolon (1.75), and petiole (1.29). The most dominant endophytes were identified as Ceratobasidium sp., Colletotrichum sp, and Fusarium sp. Ceratobasidium sp. has the highest dominance index (0.02). UPGMA cluster analysis grouped the endophytic fungi into distinct clusters based on the plant parts origin. This study implied that stolon was the the most suitable part of Asiatic pennywort for isolating endophytic fungi. Further study is required to examine the role of the endophytic fungi to produce secondary metabolites in Asiatic pennywort.

“…A common protocol for extracting FAMEs is the MIDI method (Microbial Identification System; Microbial ID, Newark, DE, USA) by which highly reproducible results have been obtained in R. solani AG-1, AG-2, AG-3, and AG-4 (Stevens Johnk and Jones 1993. Moreover, the modified MIDI method was useful for differentiating AGs within R. solani (Matsumoto et al 1997;Matsumoto and Matsuyama 1999); AG-Ba, AG-Bb, and AG-D of binucleate Rhizoctonia species (Priyatmojo et al 2002a(Priyatmojo et al , 2002b; and AG-A, AG-B(o), AG-C, AG-P, and AG-Q of binucleate Rhizoctonia species (Matsumoto 2005).…”

“…Lanoiselet et al (2005) demonstrated that the modified MIDI system gave more consistent and reproducible results than did the MIDI system for characterizing and differentiating isolates of Rhizoctonia spp. Matsumoto (2005) and Priyatmojo et al (2002b) also used a similar modified MIDI method and succeeded in characterizing the relationship between AG types and FAME profiles among isolates of Rhizoctonia ramicola, and R. fragariae, according to a classification based on differences in the host plant. Isolates of AG-A used in this experiment were not identified as R. fragariae because various species comprise the AG-A isolates.…”

Black root rot is an important disease of strawberry caused by a complex of fungi that includes species of Rhizoctonia. In this study, a modified MIDI method (Microbial Identification System) was investigated for its utility to differentiate isolates of the three different anastomosis groups (AGs) of binucleate Rhizoctonia spp., associated with strawberry black root rot complex representing AG-A, AG-G, and AG-I. A total of 11 fatty acids were detected, and the FAME profiles for isolates of the three different AGs of Rhizoctonia spp. varied quantitatively and qualitatively. Moreover, the modified MIDI method will be a useful discriminatory tool for fungal identification and classification of the AGs of binucleate Rhizoctonia spp. associated with strawberry black root rot complex.
