Trichoderma spp. are fungal species in a certain natural suppressive soil prevents the plant from infectious diseases caused by soil-borne pathogens. Among these soils borne pathogen, the fungus Rhizoctonia solani (R. solani) causes serious damages to economically significant crops and trees. The control strategies such as breeding for resistant cultivars, crop rotations, and application of fungicides are insufficient to manage diseases caused by R. solani because it persists in soil by producing sclerotia which is a hard-resistant structure. Moreover, fungicides are now unacceptable as they are not environment-friendly. The Trichoderma spp. are the potential biocontrol agents which inhibit R. solani by direct confrontation through mycoparasitic or antibiosis or competition as well as inducing plant defense responses. In this review paper, we provide first comprehensive report of a biological control activity (BCA) of Trichoderma spp. against various diseases caused by R. solani. We also report the cloning and functions of genes or proteins of Trichoderma spp. associated with suppression of diseases caused by a plant pathogen. Nevertheless, fast paced current research regarding Trichoderma spp. is required to fully exploit their actual potential against diseases caused by R. solani under field conditions.

Occurrence and diversity of basidiomycetous endophytes from the oil palm, Elaeis guineensis in Thailand

et al. 2010

View full text Add to dashboard Cite

Fungal endophytes associated with the oil palm, Elaeis guineensis, at an oil palm plantation in Trang Province, Thailand were investigated. Two samplings at the same site yielded 162 and 178 morphotypes. The overall colonization rate was 81 and 87%, respectively, with non-sporulating species being most common. Twenty strains were identified as basidiomycetes using morphological characteristics and confirmed at the molecular level using ribosomal DNA, LSU and ITS sequence data. Species included Fomitopsis cf. meliae, F. cf. ostreiformis, F. cf. pinicola, Perenniporia sp., Pycnoporus sanguineus, Trametes lactinea, and Schizophyllum commune. Leaves supported the greatest number of basidiomycetous taxa (11 strains) with five and four taxa from petioles and rachides, respectively. Twelve taxa produced poroid basidiomes in PDA culture, while the remainder had clamp-connections. Basidiomycetes occurring as saprobes on oil palm were also recorded and compared with those present as endophytes.
