Identification and analysis of MKK and MPK gene families in canola (Brassica napus L.)

Genome-wide identification and role of MKK and MPK gene families in clubroot resistance of Brassica rapa

Mitogen-activated protein kinase (MAPK or MPK) cascades play key roles in responses to various biotic stresses, as well as in plant growth and development. However, the responses of MPK and MPK kinase (MKK) in Chinese cabbage (Brassica rapa ssp. pekinensis) to Plasmodiophora brassicae, a causal agent of clubroot disease in Brassica crops, are still not clear. In the present study, a total of 11...

Physical localization and genetic mapping of the fertility restoration gene Rfo in canola (Brassica napus L.).

The Ogu cytoplasm for male sterility and its fertility restorer gene Rfo in canola (Brassica napus L.) were originally introgressed from radish (Raphanus sativus L.) and have been widely used for canola hybrid production and breeding. The objective of this study was to determine the physical location of the Rfo locus in the canola genome using fluorescence in situ hybridization and genetic mapp...

Identification and functional analysis of mitogen-activated protein kinase kinase kinase (MAPKKK) genes in canola (Brassica napus L.)

Mitogen-activated protein kinase (MAPK) signalling cascades, consisting of three types of reversibly phosphorylated kinases (MAPKKK, MAPKK, and MAPK), are involved in important processes including plant immunity and hormone responses. The MAPKKKs comprise the largest family in the MAPK cascades, yet only a few of these genes have been associated with physiological functions, even in the model p...

Biochemical and molecular analysis of glutamine synthetase gene in brassica napus L.

Influence of lead on growth and nutrient accumulation in canola (Brassica napus L.) cultivars.

Canola (Brassica napus L.) is commonly used as a hyper-accumulator for phytoextraction of heavy metals from soil and water. Like many other heavy metals, lead (Pb) contaminates soil, water and air and thus it is a great problem. This study was conducted to investigate toxic effects of Pb on growth and nutrient uptake in four canola cultivars. Each of four cultivars of canola (Con-II, Con-III, L...
