“…Recent findings have shown that endophytic fungi can help limit pathogen damage in T. cacao Evans et al, 2003;Meji'a et al, 2003;Holmes et al, 2004Holmes et al, , 2006Rubini et al, 2005;Tondje et al, 2006; Pierre Roger Tonje, IRAD, Cameroon; personal communication). Our results support these findings by showing that endophytic fungi isolated from healthy leaves and pods of T. cacao restrict in vitro growth of the three most common and economically important pathogens of cacao (P. palmivora, M. roreri, and M. perniciosa).…”

“…These observations, jointly with in vitro and in vivo studies Evans et al, 2003;Holmes et al, 2004;Rubini et al, 2005;Tondje et al, 2006;Aneja et al, 2006;Bailey et al, 2006) suggest that different endophytic fungi associated with T. cacao reduce the damage associated with pathogens in a variety of different ways in planta. Specifically, endophytes can inhibit pathogen infection and proliferation within the host directly (e.g., via antibiosis, competition, and mycoparasitism), or indirectly via inducing resistance responses intrinsic to the host (Aneja et al, 2006;Bailey et al, 2006;S.…”

“…Specifically, promising results for the control of diseases of cacao have been obtained using epiphytic mycoparasitic fungi (Krauss and Soberanis, 2001;Ten Hoopen et al, 2003). Furthermore, recent evidence shows that in some cases endophytic fungi restrict cacao pathogen growth or damage in vitro and in vivo Evans et al, 2003;Mejia et al, 2003;Holmes et al, 2004Holmes et al, , 2006Rubini et al, 2005;Tondje et al, 2006) highlighting their status as a new source of biological control agents for combating cacao pathogens. Endophytic fungi are taxonomically and biologically diverse but all share the character of colonizing internal plant tissues without causing apparent harm to their host (Wilson, 1995).…”

“…Many Trichoderma strains which were recently isolated as endophytes from tropical Theobroma cacao were described as new species; Trichoderma ovalisporum [44], Trichoderma martiale [16], Trichoderma stromaticum [45], Trichoderma theobromicola, and Trichoderma paucisporum [17], Trichoderma koningiopsis [46], and Trichoderma evansii [18]. Furthermore, an endophytic Trichoderma from Chinese yew (Taxus mairei), T. taxi, was also recently described [47].…”

Abstract:One of the biggest threats to coffee growers in East Africa are emerging vascular wilt diseases (tracheomycosis) caused by Fusarium spp. Many Trichoderma species are known to be natural antagonists of these pathogens and are widely used in biological control of fungal plant diseases. More recently, several Trichoderma spp., which exhibited high antifungal activity have been isolated as endophytes. Consequently, we have investigated the presence and the antagonistic activity of endophytic Trichoderma isolated from roots of healthy coffee plants (Coffea arabica) from the major coffee growing regions of Ethiopia. Our results showed that community of Trichoderma spp. in roots of C. arabica contains fungi from coffee rhizosphere, as well as putatively obligate endophytic fungi. The putatively -true‖ endophytic species, until now, isolated only from coffee plant ecosystems in Ethiopia and recently described as T. flagellatum and novel T. sp. C.P.K. 1812 were able to antagonize Fusarium spp., which cause coffee tracheomycosis. Moreover, we found that strains of these species are also highly antagonistic against other phytopathogenic fungi, such as Alternaria alternata, Botryotinia fuckeliana (anamorph: Botrytis cinerea), and Sclerotinia sclerotiorum.

Exploration and identification of endophytic Trichoderma in banana. Endophytic fungi Trichoderma is an organism that can used as biocontrol agent. This study aims to isolate and identify endophytic Trichoderma in roots of healthy banana plants from three districts in Yogyakarta, which will be used as biological control agent against the pathogen Fusarium oxysporum f.sp. cubense. Isolation was conducted using TSM (Trichoderma Selective Medium). We obtained six isolates of endophytic Trichoderma spp., i.e., Swn-1, Swn-2, Ksn, Psr-1, Psr-2, and Psr-3. Molecular identification was done by using ITS1 and ITS2 primer pain and sequenced. The sequence of DNA obtained was analysed and compared with NCBI database by using BLAST-N programe. The results showed that all isolates were amplified at 560-bp. Phylogenetic analysis showed that isolates Swn-1, Swn-2 and Psr-1 are homologous to Trichoderma harzianum, isolate Ksn homologous to Trichoderma asperrellum, isolate Psr-2 homologous to Trichoderma gamsii, and isolate Psr-3 homologous to Trichoderma koningiopsis, with the homologous value of 99%.
