The intensive exploration of melon crops in Sistan region favors the occurrence of root diseases such as the Rhizoctonia canker, caused by Rhizoctonia solani. In this study, eighteen melon cultivars were challenged against the pathogen aiming at selecting those potentially useful for breeding programs and/or integrated disease management. Seeds were planted in infested soil (50 mg of colonized rice grains kg-1 of soil). None of the tested melon cultivars was immune to R. solani. However… Expand

Plant growth-promoting rhizobacteria induced resistance in Jatropha curcas through phenyl propanoid metabolism against Rhizoctonia bataticola
The root rot disease in Jatropha curcas L. caused by Rhizoctonia. bataticola (Taub.) Butler has been recorded in causing 10-12 per cent mortality of 20-30 days old seedlings of Jatropha curcas inExpand

Changes in peroxidase and polyphenol oxidase activities in susceptible and resistant wheat heads inoculated with Fusarium graminearum and induced resistance
TLDR
Guaiacol-peroxidase (POX) and polyphenol oxidase (PPO) activities were measured spectrophotometrically in resistant and susceptible wheat cultivars following the inoculation with Fusarium graminearum at anthesis to show induced resistance against FHB and increased activities of POX and PPO. Expand
Resistance to downy mildew in pearl millet is associated with increased phenylalanine ammonia lyase activity.
TLDR
The induction of PAL as a response to pathogen inoculation was corroborated by a time-course study in seedlings and cultured cells of pearl millet and consistent with direct involvement of PAL in downy mildew resistance. Expand
Peroxidase activity and isozyme analysis of pearl millet seedlings and their implications in downy mildew disease resistance
TLDR
Investigation has been carried out on differential expression of peroxidase isozymes in pearl millet seedlings inoculated with downy mildew disease-causing pathogen Sclerospora graminicola, and there was a clear-cut difference between them on inoculation. Expand
Peroxidase isoenzyme patterns of resistant and susceptible wheat leaves following stem rust infection.
TLDR
Near-isogenic lines of the wheat cultivar Prelude were inoculated with race 32 of the fungus which possesses the P5 gene for avirulence, and the relationship of different isoenzymes to the lignification response as a decisive mechanism of the hypersensitive resistant reaction is discussed. Expand
Effect of plant growth promoting rhizobacteria on bacterial canker of tomato
TLDR
Use of plant growth promoting rhizobacteria in managing bacterial canker disease of tomato was studied and the rate of reduction in the bacterial cankers disease incidence was directly proportional to the amount of increased level of PAL and total phenol content. Expand
Race-specific resistance to Xanthomonas oryzae pv. oryzae conferred by bacterial blight resistance gene Xa-10 in rice (Oryza sativa) involves accumulation of a lignin-like substance in host tissues
When seedling leaves of rice ( Oryza sativa L.) cultivars carrying the Xa-10 gene for bacterial blight resistance were infiltrated with suspensions of cells from races 2 or 5 of Xanthomonas oryzaeExpand
Biochemical responses of suspension-cultured sugarcane cells to an elicitor derived from the root pathogen Pachymetra chaunorhiza
TLDR
Induced enzyme activities differed between the cell lines with Q90 (susceptible) showing a large and transitory increase in PAL activity that was far greater than that observed for Q114 (resistant). Expand
Increased Activity of a Cationic Peroxidase Associated with an Incompatible Interaction Between Xanthomonas oryzae pv oryzae and Rice (Oryza sativa).
TLDR
Accumulation of this peroxidase in extracellular spaces may play a role in the defense response in cultivar Cas 209, the rice cultivar carrying the gene Xa-10 for resistance to race 2 of Xanthomonas oryzae pvOryzae, the bacterial blight pathogen. Expand
Peroxidase Activity in Soybeans Following Inoculation with Phytophthora sojae
TLDR
Peroxidase activity was higher in race-specific resistant than in susceptible reactions at 72 h. Expand
Changes in peroxidase and polyphenoloxidase associated with natural and induced resistance of tomato to Fusarium wilt
TLDR
Ethephon treatment increased the resistance of susceptible plants to Fusarium and enhanced peroxid enzyme and polyphenoloxidase activities. Expand
