Abstract A collection of isolates the fungi Leptosphaeria maculans and L . biglobosa , which cause blackleg disease on Brassica napus (canola/oilseed rape) other Brassicaceae species, was assembled to represent global diversity these pathogens a resource for international research. The consists 226 (205 21 ) from 11 countries. genomes all 205 were sequenced, distribution identity avirulence gen...

Salinity level may affect early development of biofuel feedstock crops. The biofuel feedstock crops canola (Brassica napus L.), sorghum [Sorghum bicolor (L.) Moench], and sunflower (Helianthus annuus L.); and the potential feedstock crop sweet corn (Zea mays L.) were planted in media in pots and treated with aqueous solutions of 0, 0.1, 0.5 and 1.0 M NaCl once at: 1) planting; 2) 7-10 days afte...

Expression analysis of crop plants has improved our knowledge about the veiled underlying mechanisms for salt tolerance. In order to observe the time course effects of salinity stress on gene expression for enzymes regulating proline metabolism, we comparatively analyzed the expression of specific genes for proline metabolism in root and shoot tissues of salt-tolerant (cv. Dunkled) and salt-sen...

Several agronomic benefits can result from fall seeding of canola (Brassica spp.), but extensive research data are lacking on the potential impact of this practice on infestations of root maggots (Delia spp.) (Diptera: Anthomyiidae), which are major pests of the crop in western Canada. Field experiments making up 13 location by year combinations were conducted in central Alberta, Canada, from 1...

Leptosphaeria maculans 'brassicae' is a damaging fungal pathogen of canola (Brassica napus), causing lesions on cotyledons and leaves, and cankers on the lower stem. A related species, L. biglobosa 'canadensis', colonises cotyledons but causes few stem cankers. We describe the complement of genes encoding carbohydrate-active enzymes (CAZys) and peptidases of these fungi, as well as of four rela...

Abstract The ideal-free distribution and central-place foraging are important ecological models that can explain the of organisms in their environment. However, this model ignores distance-based costs from a central place (hive, nest), whereas competition. Different currencies cooperation between foragers also create different optimal distributions foragers, but limited to simple two-patch mode...

Interest in oilseeds and oilseed crop production has recently been heightened by the growing potential for biofuels. Traditional oil seed crops, such as sunflower (Helianthus annuus L., Asteraceae), flax (Linum usitatissimum L., Linaceae), and more recently canola (Brassica napus L., Brassicaceae) have become crops of major importance in the region. The key to their production success is multi-...
