Evolution of linked avirulence effectors in Leptosphaeria maculans is affected by genomic environment and exposure to resistance genes in host plants [PDF]

, 2010
Brassica napus (canola) cultivars and isolates of the blackleg fungus, Leptosphaeria maculans interact in a ‘gene for gene’ manner whereby plant resistance (R) genes are complementary to pathogen avirulence (Avr) genes.

Temporal dynamics of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine interspecific competition and disease development on oilseed rape

Pest Management Science, EarlyView.
This study provides evidence that the timing of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine the outcome of interspecific competition and disease development on their host oilseed rape. Abstract BACKGROUND Phoma stem canker is one of the most economically damaging diseases of oilseed rape, caused by co‐existing fungal ...

First report of Leptosphaeria biglobosa ‘brassicae’ as causal agent of phoma leaf spot in Brassica napus (Canola) in Argentina [PDF]

, 2018
Canola(Brassicanapus L.) is the second largest oilseed crop in the worldproviding 13% of the world´s oil supply. This crop has been grown in Argentinasince the 1930s, and the area devoted to its cultivation varies every year,reaching a maximum of 95000 ...

Leaf senescence and nitrogen remobilization efficiency in oilseed rape (Brassica napus L.) [PDF]

Journal of Experimental Botany, 2014
Despite its worldwide economic importance for food (oil, meal) and non-food (green energy and chemistry) uses, oilseed rape has a low nitrogen (N) use efficiency (NUE), mainly due to the low N remobilization efficiency (NRE) observed during the vegetative phase when sequential leaf senescence occurs.

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Pest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Organic farming and gene transfer from genetically modified crops [PDF]

, 1999
This is the final report of MAFF/Defra project OF0157. Genetically modified (GM) crops cannot be released into the environment and used as food, feed, medicines or industrial processing before they have passed through a rigorous and internationally ...

Impact of shortened crop rotation of oilseed rape on soil and rhizosphere microbial diversity in relation to yield decline [PDF]

, 2013
Oilseed rape (OSR) grown in monoculture shows a decline in yield relative to virgin OSR of up to 25%, but the mechanisms responsible are unknown. A long term field experiment of OSR grown in a range of rotations with wheat was used to determine whether ...

Community composition, abundance and activity‐density of carabids and staphylinids depend on prey abundance and adjacent habitat even in diverse agricultural landscapes

Pest Management Science, EarlyView.
Carabid and staphylinid communities are shaped by adjacent habitat type, prey availability and landscape context, influencing natural pest control across agricultural landscapes. Abstract BACKGROUND The functioning of agroecosystems depends on key ecosystem processes that deliver ecosystem services, yet agricultural management has increasingly shifted ...

Pangenomic structural variant patterns reflect evolutionary diversification in Brassica napus

Genome Biology
Background Understanding genetic diversity is crucial for enhancing crop productivity. This study explores species-wide genome structural variation (SV) and its role in intraspecific and ecogeographical diversification of Brassica napus, a recently ...

Safety of Oilseed Rape Straw Mulch of Different Lengths to Rice and Its Suppressive Effects on Weeds

Agronomy, 2020
Rice is widely grown after harvesting of oilseed rape (Brassica napus L.) in many countries. Experiments were carried out under greenhouse and field conditions to assess the impact of oilseed rape straw mulch on rice and paddy weeds.
