Trichoderma harzianum is well known to exhibit induced systemic resistance (ISR) to Curvularia leaf spot. We previously reported that a C6 zinc finger protein (Thc6) is responsible for a major contribution to the ISR to the leaf disease, but the types of effectors and the signals mediated by Thc6 from Trichoderma are unclear. In this work, we demonstrated that two hydrolases, Thph1 and Thph2, f...

Although a wide application of pesticides and herbicides are an essential part of augmenting crop yields, excessive use of these chemicals leads to the microbial imbalance of soil, environmental pollution and health hazards to human and animals. An ideal pesticide should have the ability to destroy target pests quickly and should get degrade the toxic and nontoxic substances as quickly as possi...

understanding the function of trichoderma species in the control of phytophthora drechsleri in pistachio orchards is very important.  in this study, the effects of liquid extra-cellular secretions and volatile compounds secreted by 27 isolates of trichoderma harzianum, t. crassum, t. koningii, t.aureoviride, t. asperellum, t. brevicompactum, t.longibrachiatum and t. virens were investigated on ...

Filamentous fungi from the genus Trichoderma have been widely investigated due to their considerable production of important biotechnological enzymes. Previous studies have demonstrated that the T. harzianum strain IOC-3844 has a high degree of cellulolytic activity. After excluding the native signal peptide, the open reading frame of the T. harzianum endoglucanase III enzyme was cloned in...

Media and culturing protocols were identified that supported the formation of submerged conidia and microsclerotia (MS) by Trichoderma harzianum Rifai strain T-22 using liquid culture fermentation. Liquid media with a higher carbon concentration (36 g L(-1)) promoted MS formation at all C:N ratios tested. Hyphae aggregated to form MS after 2 d growth and after 7 d MS were fully melanized. This ...

Trichoderma harzianum is one of the most beneficial microorganisms applied on diverse crops against biotic and abiotic stresses and acts also as a plant growth-promoting fungus. Here, we report the genome of T. harzianum B97, originating from a French agricultural soil and used as a biofertilizer that can tolerate abiotic stresses.

Abstract Background Early blight disease of tomato caused by pathogenic fungi Alternaria solani is the most significant and common throughout world as well in Kingdom Saudi Arabia. The aim this study was to isolate identify native Trichoderma species from Jeddah region Arabia; evaluate their antagonistic potential against A. ; influence early severity greenhouse open field. Results present focu...

the use of resistant plant cultivars and parasitoids could be an effective strategy in ipm of liriomyza sativa blanchard. cucumber is a preferable host for this insect. in this research, antixenosis resistance of 17 cultivars of cucumber was evaluated to l. sativae under greenhouse condition. results indicated that there were significant differences between cultivars with regard to the number o...

To examine the genetic variation for drought stress in chamomile, eight accessions belonging to four species were evaluated under both field and greenhouse conditions using normal and late season drought stress. In the field experiment drought stress were initiated with irrigation cease at the commencement of flowering time. In greenhouse experiment, irrigation carried out at flower initiation ...
