trichoderma spp. are known as efficient plant growth promoting agents. hence, enrichment of soil by appropriate population of trichoderma is useful and important for effective plant growth promote. present study aimed to investigate the plant growth promoting effects of five strains of the genus trichoderma species include: trichoderma harzianum tr6, t. harzianum t22, t. asperellum t34, t. atro...

Employing Illumina Hiseq whole genome metagenome sequencing approach, we studied the impact of Trichoderma harzianum on altering the microbial community and its functional dynamics in the rhizhosphere soil of black pepper (Piper nigrum L.). The metagenomic datasets from the rhizosphere with (treatment) and without (control) T. harzianum inoculation were annotated using dual approach, i.e., stan...

The investigation was undertaken to enhance the decomposition process by pre-treatment of rice stubble, having higher concentration of lignin. Air-dried rice stubble was treated with 1.8 liter of 1% NaOH and autoclaved. Six cellulolytic fungi, Trichoderma harzianum, Penicillium citrinum, Curvularia lunata, Aspergillus flavus and Alternaria alternata were grown in basal synthetic medium along wi...

The aim of this study was to develop a protocol for the production of fungal bio-pesticides with high efficiency, low cost, and non-polluting fermentation, while also increasing their survival rate under field conditions. This is the first study to develop biocontrol Trichoderma harzianum transformants TS1 that are resistant to benzimidazole fungicides. Agricultural corn stover and wheat bran w...

A plate confrontation experiment is commonly used to study the mechanism by which Trichoderma spp. antagonize and parasitize other fungi. Previous work with chitinase gene expression (ech42) during the precontact period of this process in which cellophane and dialysis membranes separated Trichoderma harzianum and its host Rhizoctonia solani resulted in essentially opposite results. Here, we sho...

in the present study, the diversity of trichoderma spp. was investigated in alkaline pistachio soils at different geographic area in kerman province, iran. a total of 161 trichoderma isolates were obtained and identified at the species level by analysis of their morphological characters and sequence analysis of their internal transcribed spacer regions of the rrna cluster and tef1 genes as phyl...

Recently, we found that fungi are involved in breaking seed dormancy of Opuntia streptacantha, and that the effect of fungi on seeds is species-specific. However, the effect of fungi on seed germination from other Opuntia spp has not been evaluated. Thus, we evaluated the effect of four fungal species (Penicillium chrysogenum, Phoma sp., Trichoderma harzianum, Trichoderma koningii) on the germi...

Acifluorfen enhancement of blue-light mediated phototropism suggested that this diphenyl-ether herbicide augments the light reaction (TY Leong, WR Briggs 1983 Plant Physiol 70: 875-881). The separation of the possible direct interaction of acifluorfen with light reactions from interactions with dark pathways has been elucidated in this paper with Trichoderma harzianum. Acifluorfen at 30 micromo...

Trichoderma harzianum IS005-12 promotes germination, seedling growth and seedborne fungi suppression in Italian ryegrass forage | Nevena Banjac, Rade Stanisavljević, Ivica Dimkić, Nataša Velijević, Marina Soković, Ana Ćirić Agricultural Journals

Green mold disease (causal agent, Trichoderma) has resulted in severe crop losses on mushroom farms worldwide in recent years. We analyzed 160 isolates of Trichoderma from mushroom farms for morphological, cultural, and molecular characteristics and classified these isolates into phenotypic groups. The most common group comprised approximately 40% of the isolates and was identified as a strain ...
