Disease relevance of Rhizoctonia


High impact information on Rhizoctonia


Biological context of Rhizoctonia

  • Biocontrol activity against damping-off diseases caused by Pythium ultimum and Rhizoctonia solani was not reduced by the Psy1 disruption, suggesting that iron competition through dimerum acid production does not contribute significantly to disease suppression activity under the conditions used [8].
  • Biotransformation of the phytoalexin camalexin by the phytopathogen Rhizoctonia solani [9].
  • Four esophageal- and ruminal-cannulated Angus steers (avg weight, 308 kg) were used to investigate how salivation is affected by the administration of purified slaframine (SF; 1-acetoxy-6-aminooctahydroindolizine), a cholinergic secretagogue isolated from Rhizoctonia leguminicola [10].
  • A double-stranded (ds)RNA, designated as M2, is associated with hypovirulence, conversion of the quinic acid pathway from inducible to constitutive and downregulation of the shikimic acid pathway in the Rhizoctonia solani culture Rhs 1A1 [11].

Associations of Rhizoctonia with chemical compounds


Gene context of Rhizoctonia

  • Moreover, a positive correlation between suppression of Rhizoctonia solani AG3 and microbial diversity was observed [15].
  • The lectin isolated from the phytopathogenic basidiomycete Rhizoctonia solani (RSA) is a homodimer of two noncovalently associated monomers of 15.5 kDa [16].
  • It was the first leguminous TLP-like protein demonstrated to exert antifungal activity against Fusarium oxysporum, Pleurotus ostreatus, and Coprinus comatus but not against Rhizoctonia solani [17].
  • The pseudo-oligosaccharides, validamycins, showed potent inhibitory activity against trehalase of Rhizoctonia solani while no significant inhibition was exhibited against cellulase, pectinase, chitinase, alpha-amylase, alpha- and beta-glucosidases [18].
  • As the Rhizoctonia mycelia aged, there was an increase in both the total and the specific activities of the RNase present in the mycelia [19].

Analytical, diagnostic and therapeutic context of Rhizoctonia

  • Maximal levels of L-henylalanine ammonia-lyase activity were observed when the mycelial felts of Rhizoctonia solani were grown for 4.5 days on Byrde synthetic medium containing 3.5% glucose and 0.3% L-phenylalanine, Differential centrifugation studies have indicated that the enzyme is localized in the soluble fraction [20].
  • Amino acid fraction of the three fungi, determined through paper chromatography, contained all the 8 essential amino acids in addition to 9 odd amino acids, except in the case of Rhizoctonia melongina in which the essential amino acid lysine was lacking [21].
  • Bioassay of chitinase activity of transgenic lines on in vitro condition prevented mycelial growth of Rhizoctonia solani in comparison with untransformed control leaf extract [22].
