In the present study, we have evaluated comparative biochemical defense response generated against Alternaria alternata and its purified toxins viz. alternariol (AOH), monomethyl ether (AME), tenuazonic acid (TeA). The necrotic lesions developed due to treatment with were almost similar as those produced by pathogen, indicating crucial role of these in plant pathogenesis. An oxidative burst reaction characterized rapid transient production a large amount reactive oxygen species (ROS) occurs...

Plant defense against their pathogens can be induced by a complex network of different inducers. The present study investigates the synergistic effect Trichoderma harzianum, exogenous salicylic acid (SA) and methyl jasmonate (MeJA) over response regulation antioxidant mechanisms lipid peroxidation in tomato plants Fusarium wilt disease. In work, were infected oxysporum f. sp. lycopersici 3 days after inoculated with T. harzianum and/or sprayed daily for chemical inducers (SA MeJA). Plants...

Trichoderma spp. are well-known biological agents that have significant antagonistic activity against several plant pathogenic fungi. In the present study, were tested in vitro for their different of Fusarium and Alternaria viz. alternata, A. brassicae, solani, oxysporum F. solani using dual plate assay by production volatile non-volatile compounds. The results obtained revealed harzianum T. viride effectively inhibited growth spore Alternaria. highest inhibition was found alternata 62.50%...

Vascular wilt of tomato caused by Fusarium oxysporum f.sp. lycopersici (FOL) is one the most devastating diseases, that delimits production worldwide. Fungal short-chain dehydrogenases/reductases (SDRs) are NADP(H) dependent oxidoreductases, having shared motifs and common functional mechanism, have been demonstrated as biochemical targets for commercial fungicides. The 1,3,6,8 tetra hydroxynaphthalene reductase (T4HNR) protein, a member SDRs family, catalyzes naphthol reduction reaction in...

Abstract Alternaria species produce various sorts of toxic metabolites during their active growth and causes severe diseases in many plants by limiting productivity. These incorporate mycotoxins comprising dibenzo-α-pyrone some tetramic acid derivatives. In this study, we have screened out total 48 isolates from different belonging to locations India, on the basis pathogenic nature. Pathogenicity testing these strains susceptible tomato variety (CO-3) showed 27.08% were highly pathogenic,...

In the present study, Paenibacillus dendritiformis, Trichoderma harzianum, and asperellum were appraised as potential biocontrol agents that induce resistance in chilli (Capsicum annuum) against devastating pathogen Colletotrichum truncatum, which causes anthracnose. Bright-field scanning electron micrographs showed hyphal degradation, lysis, abnormal swelling C. truncatum P. dendritiformis a dual plate assay. Under greenhouse conditions, seeds pretreated with T. asperellum, + harzianum by...

The beneficial association and interaction of rhizocompetent microorganism are widely used for plant biofertilization amelioration stress-induced damages in plants. To explore the regulatory mechanism involved defense while associating with microbial species, their interplay when co-inoculated pathogen, we evaluated response tomato defense-related WRKY gene transcripts. present study was carried out to examine qRT–PCR-based relative quantification differently expressed defence-related genes...
