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...
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...
Abstract Fungi are one of the most diverse groups organisms with an estimated number species in range 2–3 million. The higher-level ranking fungi has been discussed framework molecular phylogenetics since Hibbett et al., and definition higher ranks (e.g., phyla) ‘true fungi’ have revised several subsequent publications. Rapid accumulation novel genomic data advancements now facilitate a robust precise foundation for classification within kingdom. This study provides updated kingdom , drawing...
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...
Trichoderma asperellum and T. harzianum were assessed in this study as a potential biological control against Colletotrichum truncatum. C. truncatum is hemibiotrophic fungus that causes anthracnose disease chilli thereby affecting plant growth fruit yield. Scanning electron microscope (SEM) technique showed the beneficial interaction between root-Trichoderma spp. inducing promotion, mechanical barrier, defense network under challenged conditions.Seeds bio-primed with asperellum, harzianum, +...
Tomato is considered as one of the most important sources nutrients such lycopene, β-carotene, flavonoids, ascorbic acid (vitamin C) and hydroxyl-cinnamic derivatives. The quality quantity in tomato fruits were decreased during severe infection Alternaria alternata. present study deals with estimation phenolic content which infected A. alternata its toxins tenuazonic (TeA), alternariol (AOH) monomethyl ether (AME). found lowest pathogen-infected i.e. (0.66 ± 0.03 mg/g), (0.14 0.01 (1.89 0.2...
The WRKY transcription factors have indispensable role in plant growth, development and defense responses. differential expression of genes following the stress conditions has been well demonstrated. We investigated temporal tissue-specific (root leaf tissues) defense-related genes, infection Fusarium oxysporum f. sp. lycopersici (Fol) tomato. genome-wide computational analysis revealed that during Fol tomato, 16 different members gene superfamily were found to be involved, which only three...
Microbial priming represents an adaptive strategy to enhance the plant defense against subsequent challenges incited by pathogenic microbes. The aim of study was investigate effect with Trichoderma harzianum (Th) on induced resistance potential tomato after challenged Fusarium oxysporum f. sp. lycopersici (Fol) pathogen. This work demonstrated antioxidative and related enzyme activities qRT-PCR mechanisms plants bioprimed T. Fol biopriming resulted into enhanced expression defense-related...
Hydrolytic enzymes (cellulase, pectinase, xylanase) producing bacteria were isolated from compost, garden soil and wastewater. Out of 63 bacterial isolates, CMB10 SFMB9, selected for study due to their enzymatic potential, with relative enzyme activity ranging 0.5 0.8. Both Gram-negative, rod-shaped non-motile. They phenotypically characterized concerning Bergey's Manual Determinative Bacteriology followed by molecular characterization 16S rRNA gene sequencing SFMB9 identified as Olivibacter...
In the present study, seven chytrid species from genus Rhizophydium, specifically Rhizophydium annulatum, R. coronum, condylosum, elyense, keratinophilum, sphaerotheca and utriculare were collected north India are briefly described. The descriptions accompanied by photographs illustrating their morphological taxonomical characteristics. Notably, elyense represent first records of these in Indian mycobiota.
