Canola (oilseed rape, Brassica napus L.) is susceptible to infection by the biotrophic protist Plasmodiophora brassicae, the causal agent of clubroot. To understand the roles of microRNAs (miRNAs) during the post-transcriptional regulation of disease initiation and progression, we have characterized the changes in miRNA expression profiles in canola roots during clubroot disease development and...

In this study, bacteria were isolated from the rhizosphere and inside the roots of canola (Brassica napus L.) plants grown in the field from northern Iran. Firstly, 150 strains (endophytic and rhizospheric isolates) isolated from canola were characterized for plant growth promoting (PGP) traits. Of them, one hundred isolates produced indole3-acetic acid (IAA), whereas 17 isolates solubilized ph...

Morphometric, electrophoretic, and immunological procedures were used to probe the structural and physiological differences between triazine-resistant (R) and susceptible (S) isolines of canola (Brassica napus L.). The R biotype exhibited increased grana stacking and decreased amounts of starch compared to the S biotype. Likewise, characters associated with an increase in grana stacking (lower ...

Lodging, defined as the permanent displacement of aboveground parts, is a common problem to cause yield loss, deterioration in seed quality and difficult to harvest in canola (Brassica napus L.) crop production. This study aimed to develop a method for assessing crop lodging, to examine how agronomic practices affected the relationships between root lodging and electrical capacitance traits. Ca...

Five avirulence genes from Leptosphaeria maculans, the causal agent of blackleg of canola (Brassica napus), have been identified previously through map-based cloning. In this study, a comparative genomic approach was used to clone the previously mapped AvrLm2. Given the lack of a presence-absence gene polymorphism coincident with the AvrLm2 phenotype, 36 L. maculans isolates were resequenced an...

in order to study the effect of flaming on seed viability of sinapis arvensis l., changes in microorganisms population and physicochemical characteristics of soil after canola (brassica napus l.) harvesting, an experiment was carried out based on randomized complete block design with four replications and eight treatments at karaj research center, iran, during 2005- 2006. after harvesting canol...

To study drought stress on seedling dry weight, proline contents and evaluate of antioxidant enzymes activity in canola genotypes (Brassica napus l.), an experiment were evaluated at laboratory physiology, Shahed University. This experiment was carried out in factorial with CRD design with 4 replications in 2008. The first factor was including levels of dough stress, one without stress as check...

The objective of the present study was to describe the trend of germination characteristics for a variety of canola ‘Okapi’ at different pre-soaking durations. For this purpose, seeds were placed in 250 ml of distilled water for 0 to 12h with intervals of 2h at room temperature. Each sample of seed was placed in Petri-dishes and germinated at the temperature of 25°C. Fitting logistic function o...
