Clubroot disease, caused by the obligate biotrophic protist Plasmodiophora brassicae Woronin, is one of the most economically important diseases of Brassica crops in the world. Although many clubroot resistance (CR) loci have been identified through genetic analysis and QTL mapping, the molecular mechanisms of defense responses against P. brassicae remain unknown. Fine mapping of the Crr1 locus...

Cabbage aphid, Brevicornye brassicae (Linnaeus) is one of the major insect pests cabbage. Chemical control mostly used to manage this pest. The present investigation was conducted evaluate an environmentally benign approach for pest management through different entomopathogenic mycoformulations against nymphs B. identify effective mycoformulation. effect supplemented with adjuvants Brassicae al...

Alternaria brassicae is a necrotrophic fungus causes blight disease in oilseed mustard crop. There 47% loss of the crop due to disease. To control this disease, various chemical fungicides have been used till date which are harmful our environment. Zinc oxide (ZnO) nanoparticles synthesized from Terminalia bellerica reported significant antifungal potential against A. at 200 ppm concentration. ...

Several 2,6-bis-(un)substituted phenoxymethylpyridines were synthesized and evaluated in vitro against Fusarium graminearum, Helminthosporium sorokinianum, Alternaria brassicae, Alternaria alternata, and Fusarium oxysporum f. sp. vasinfectum. Among all derivatives, compound 3a exhibited a broad-spectrum antifungal activity against the five phytopathogenic fungi.

In this article, the biology and fertility life table parameters of the cabbage aphid, Brevicoryne brassicae (L.) (Hemiptera: Aphididae), were studied on cauliflower leaves, Brassica oleracea var. botrytis (Brassicales: Brassicaceae), of the cultivars Smilla, Snow mystique, White cloud, Buris, Galiblanka, Snow crown, SG, and Tokita. This study was conducted under controlled conditions: 25 ± 2°C...

In the arms race between plants, herbivores, and their natural enemies, specialized herbivores may use plant defenses for their own benefit, and variation in plant traits may affect the benefits that herbivores derive from these defenses. Pieris brassicae is a specialist herbivore of plants containing glucosinolates, a specific class of defensive secondary metabolites. Caterpillars of P. brassi...

Camalexin has been reported to play defensive functions against several pathogens in Arabidopsis. In this study, we investigated the possible role of camalexin accumulation in two Arabidopsis genotypes with different levels of basal resistance to the compatible eH strain of the clubroot agent Plasmodiophora brassicae. Camalexin biosynthesis was induced in infected roots of both Col-0 (susceptib...
