Abstract:

Responses of rice to Magnaporthe grisea and Cochliobolus miyabeanus were compared. In Tetep, a rice cultivar resistant to both fungi, pathogen inoculation rapidly triggered the hypersensitive reaction (HR), resulting in microscopic cell death. In rice cv. Nakdong, susceptible to both pathogens, M. grisea did not cause HR, whereas C. miyabeanus caused rapid cell death similar to that associated with HR, which appeared similar to that observed in cv. Tetep, yet failed to block fungal ramification. Treatment with conidial germination fluid (CGF) from C. miyabeanus induced rapid cell death in both

Abstract:

Agriculture is a source of living in many areas and acts a backbone for the Indian economy. Agriculture crops are affected by fungus and bacteria to cause diseases in the plant. Brown spot is a serious hazard that takes place on leaves of the rice plant. The presence of fungus ‘Cochliobolus miyabeanus’ is the main factor for brown spot disease. The severity of the disease depends on growth of the fungus. The development of fungus depends on several factors such as temperature, humidity and rainfall. Whenever the disease occurs on a plant, level of the infection plays an importance

This article 'A Comparative Study of Six Isolates of Cochliobolus miyabeanus in Rice From U.S.A' appeared in the International Rice Research Newsletter series, created by the International Rice Research Institute (IRRI). The primary objective of this publication was to expedite communication among scientists concerned with the development of improved technology for rice and for rice based cropping systems. This publication will report what scientists are doing to increase the production of rice in as much as this crop feeds the most densely populated and land scarce nations in the world.

Deletion of the PPT1 gene, from the maize pathogen Cochliobolus heterostrophus and the rice pathogen Cochliobolus miyabeanus, yielded strains that were significantly reduced in virulence to their hosts.

Cochliobolus miyabeanus forms a specialized infection structure, an appressorium, to infect its host rice plants. Curtailment of prepenetration development by spermidine and spermine was more evident in appressorium development and germination remained unaffected, whereas putrescine and methylglyoxal-bis-guanyl hydrazone (MGBG) impaired both morphogenetic events. Exogenous calcium nullified the inhibitory effect of MGBG on the prepenetration development in vitro and in vivo and the disease progression. High levels of polyamines were detected in freshly collected conidia, but the amounts were r

Abstract:

AbstractNecrotrophic pathogen Cochliobolus miyabeanus (C. miyabeanus) causes rice brown leaf spot disease and drastically affects the yield and quality of rice grains. However, the molecular mechanism of rice-C. miyabeanus remains poorly understood due to the limited research conducted on this pathosystem. To elucidate the molecular mechanism of rice-C. miyabeanus, a transcriptome analysis was conducted from in vitro and in planta grown C. miyabeanus. This analysis led to the identification of a total of 24,060 genes of which 426 in vitro and 57 in planta expressed genes were predicted to enco

Abstract:

Agriculture is a source of living in many areas and acts a backbone for the Indian economy. Agriculture crops are affected by fungus and bacteria to cause diseases in the plant. Brown spot is a serious hazard that takes place on leaves of the rice plant. The presence of fungus ‘Cochliobolus miyabeanus’ is the main factor for brown spot disease. The severity of the disease depends on growth of the fungus. The development of fungus depends on several factors such as temperature, humidity and rainfall. Whenever the disease occurs on a plant, level of the infection plays an importance in crop yiel

Abstract:

Cochliobolus miyabeanus is an important plant pathogen which causes a very common and widespread brown spot disease in rice, that may result in a severe reduction in the crop yield. The current studies were carried out to search out the antifungal potential of the bacterial isolates from the rhizospheric region of Daucus carota against brown spot fungus, C. miyabeanus. Isolation of rhizospheric bacterial isolates was done from carrot grown field of district Jaunpur in month of January, 2023.

Abstract:

A polyketide known as cladospolide B, (Z)-4,5-dihydroxy-2-dodecen-11-olide was isolated from the culture broth of the fungus, Lambertella brunneola. The structure elucidation of this compound was based on Nuclear Magnetic Resonance (NMR) spectroscopic data and Mass Spectroscopy (MS) analyses. Cladospolide B exhibited a seemingly weak antifungal activity and inhibited the hyphalgrowth of the phyto-pathogenicfungus, Helminthosporium oryzae(=Cochliobolus miyabeanus) by 50 % at more than 1 mg/mL but less than 5 mg/mL (1 < IC50 <5). This is the first report on the isolation of cladospolide B

ABSTRACT Waitea circinata (Warcup & Talbot) is an orchid antagonist mycorrhizal fungus with biocontrol potential against rice pathogens. This study aimed to optimize the extraction method, obtain a new extract and evaluate its efficiency against rice pathogens in vitro and in vivo, as well as to compare it with other extraction methods and W. circinata. The extracts were obtained and screened for in vitro growth inhibition against the pathogens Cochliobolus miyabeanus, Monographella albescens and Sarocladium oryzae, using the following extracts: mycelial, crude, lyophilized and mycelial ma

Abstract:

Abstract Green leaf volatiles (GLVs), volatile organic compounds released by plants upon tissue damage, are key signaling molecules in plant immunity. The ability of exogenous GLV application to trigger an induced resistance (IR) phenotype against arthropod pests has been widely reported, but its effectiveness against plant pathogens is less well-understood. In this study, we combined mRNA sequencing-based transcriptomics and phytohormone measurements with multispectral imaging-based precision phenotyping to gain insights into the molecular basis of Z-3-hexenyl acetate induced resistance (Z-3-

AbstractPathogens utilize multiple types of effectors to modulate plant immunity. Although many apoplastic and cytoplasmic effectors have been reported, nuclear effectors have not been well characterized in fungal pathogens. Here, we characterize two nuclear effectors of the rice blast pathogen Magnaporthe oryzae. Both nuclear effectors are secreted via the biotrophic interfacial complex, translocated into the nuclei of initially penetrated and surrounding cells, and reprogram the expression of immunity-associated genes by binding on effector binding elements in rice.

Rice is the global staple food, contributing over half of the world’s agricultural production. Excessive fungicide use in rice farming poses environmental, fungicide resistance, and beneficial microbial disruption concerns, making biocontrol, particularly bacteria, a promising biocontrol agent due to their rapid growth, ease of handling, and robust colonization attributes. Endophytes are endosymbionts residing within host plants, playing a pivotal role in plant health without inciting any pathogenic effects. In this study, we investigated the antagonistic potential of four characterized bacter
