Mitochondrially encoded cox2 sequences were used to infer evolutionary relationships of downy mildew and white rust taxa in a data set of 36 peronosporomycete isolates. The data set of 599 aligned nucleotides was analysed using neighbor joining, maximum parsimony, and maximum likelihood. These phylogenetic analyses did not infer separate monophyletic orders for the Pythiales versus downy mildew...

Abstract Brassica juncea var . tumida (tumorous stem mustard) is widely cultivated as a feature vegetable in Ningbo, Zhejiang Province, and used raw material for pickles China. White blister rust, caused by Albugo candida , has severe negative effects on tumorous mustard, resulting significant economic losses. In this study, hypha colonization extension, haustorial formation, the development pr...

Background: Mustard is one of the most important cruciferous crops which are grown basically for oil. The crop infected by many diseases prominently fungal cause limitation in productivity crop. White rust (Albugo candida) and Alternaria blight (Alternaria brassicae) serious mustard. Methods: study was conducted to find out resistant response mustard varieties against these diseases. A field ex...

The present investigation was carried out to identify the potential donors of resistant gene(s)/the source white rust disease in B. juncea using 30 genotypes, including locally adapted accessions and advanced breeding lines. Out ten lines viz. Bio-YSR, CAULC-1, CAULC-2, CAULC-3, CAULC-4, CAURM-2, CAULR-7, CAURM-4, CAURM 4-1, 4-2 exhibited a lower PDI value (lesser than mean 10.83) with superior...

The Pseudomonas syringae-Arabidopsis (Arabidopsis thaliana) interaction is an extensively studied plant-pathogen system. Arabidopsis possesses approximately 150 putative resistance genes encoding nucleotide binding site (NBS) and leucine-rich repeat (LRR) domain-containing proteins. The majority of these belong to the Toll/Interleukin-1 receptor (TIR)-NBS-LRR (TNL) class. Comparative studies wi...
