on the basis of preliminary in vitro screening tests, a competent strain of pantoea agglomerans ena1 (p. agg. ena1) recovered from soybean nodule was evaluated for its antagonistic activity against macrophomina phaseolina causal agent of charcoal rot of soybean. the results of various in vitro assays showed that p. agg. ena1 is capable of exerting strong antagonistic effect against m. phaseolin...

This paper reported on the various filamentous fungi strains that were isolated from a wild grown Catharanthus roseus. Based on the morphological characteristics and molecular technique through a Polymerase Chain Reaction and DNA sequencing method using internal transcribed spacer (ITS), these fungi had been identified as a Colletotrichum sp., Macrophomina phaseolina, Nigrospora sphaerica and F...

In this paper we show that hydroxyapatite nanoparticles (NP) can not only act as a chaperon (by imparting thermostability) but can serve as a synthetic enhancer of activity of an isolated extracellular pectate lyase (APL) with low native state activity. The purified enzyme (an attenuated strain of Macrophomina phaseolina) showed feeble activity at 50°C and pH 5.6. However, on addition of 10.5 µ...

A total of 360 bacteria, isolated from the rhizospheres of a system of rice intensification (SRI) fields, were characterized for the production of siderophore, fluorescence, indole acetic acid (IAA), hydrocyanic acid (HCN) and solubilization of phosphorus. Of them, seven most promising isolates (SRI-156, -158, -178, -211, -229, -305 and -360) were screened for their antagonistic potential again...

Agricultural and wild ecosystems may interact through shared pathogens such as Macrophomina phaseolina, a generalist clonal fungus with more than 284 plant hosts that is likely to become more important under climate change scenarios of increased heat and drought stress. To evaluate the degree of subdivision in populations of M. phaseolina in Kansas agriculture and wildlands, we compared 143 iso...

Macrophomina phaseolina é um fitopatógeno de solo com ampla distribuição geográfica, responsável por ocasionar perdas econômicas graves incitando sintomas podridões no sistema radicular e caule das plantas infectadas. Há uma demanda mundial crescente novos tratamentos, que promovam a segurança alimentar nutricional, substâncias mais eficazes menos danosas ao equilíbrio dos ecossistemas. O objet...

O feijão-caupi possui grande importância por fazer parte do hábito alimentar da população e ser uma das principais fontes de renda emprego. As doenças estão entre os fatores limitantes produtividade feijão-caupi, enfermidades que acometem ao é causada pelo fungo Macrophomina phaseolina. Em busca um desenvolvimento agrícola sustentável, o uso agentes controle biológico considerado alternativa vi...
