Phosphorus (P) is an important element for crop productivity and is widely applied in fertilizers. Most P fertilizers applied to land are sorbed onto soil particles, so research on improving plant uptake of less easily available P is important. In the current study, we investigated the responses in root morphology and root-exuded organic acids (OAs) to low available P (1 μM P) and sufficient P ...

Abstract: A greenhouse study was conducted to assess growth and elemental uptake by canola (Brassica napus) on acidic soils amended with four chemically different unweathered fly ashes. The ashes were incorporated into the top 10 cm of 1 m long intact soil cores at the rates of 0, 12, 36 and 108 Mg ha. The objective of this study was to characterise growth responses and distribution of B, Mo an...

Leptosphaeria maculans is a fungal pathogen causing blackleg in canola. Its virulence has been attributed, among other factors, to the activity of hydrolytic cell wall degrading enzymes (CWDEs). Studies on the pathogenicity function of CWDEs in plant pathogenic fungi have been difficult due to gene redundancy. In microorganisms many CWDE genes are repressed by glucose and derepressed by the fun...

the engineering of transgenic canola (brassica napus l. ) to make tolerance to the broad-spectrum herbicide, glyphosate, is one of the most effective approaches for weed management. glyphosate inhibits the enzyme epsps (5-enolpyruvylshikimate-3-phosphate synthase) enzyme which functions in the shikimate pathway and has a key role in biosynthesis of aromatic amino acids required for survival of ...

In addition to the primary use of canola in oil pressing, canola is important as a feed supplement for livestock. We have developed a new approach (termed PiggyBackTM expression) that can be used to enhance the histidine content of canola protein. Using PiggyBackTM expression (a novel recombinant approach for generically improving the amino acid composition in crop plants) the histidine content...

Leptosphaeria maculans is the major pathogen of canola (oilseed rape, Brassica napus) worldwide. In Australia, the use of azole fungicides has contributed to the 50-fold increase in canola production in the last 25 years. However, extensive application of fungicides sets the stage for the selection of fungal populations with resistance. A high-throughput in planta assay was developed to allow s...

   Phenolic extracts of canola (Brassica napuse L.) contains substances that inhibited the germination and seedling growth of soybean (Glycin max L.). These compounds also affect activity of some enzymes. Hear, we investigated the allelopathic effects of various canola plant parts on soybean germination, seedling growth, and biochemical aspects. Phenolic extract of canola shoot (including leaf,...

Soil salinity is one of the major abiotic stresses that adversely affect plant productivity and quality. Therefore, an experiment was conducted to investigate the effects of seed treatment with L-arginine on some morphological and physiological parameters of Brassica napus under salinity stress. The seeds of canola were pre-treated with three arginine concentrations (0, 5, and 10µM Arg) for 24 ...

Magnetic gold nanoparticles (mGNPs) with uniform size and morphology synthesized by our sonication treatment method were covalently bound with fluorescein isothiocyanate (FITC) molecules. Driven by an external magnetic field, FITClabelled nanoparticles were delivered into plant cells with and without cell walls, evident from sectional transmission electron microscopy images. Confocal images fur...
