First record of verticillium wilt (Verticillium longisporum) in winter oilseed rape in the UK [PDF]

open access: yes, 2011
Verticillium longisporum is an important pathogen of oilseed rape (OSR) and vegetable brassicas in several European countries, but has not been reported previously in the UK (Karapapa et al., 1997; Steventon et al., 2002).

Current and previous spatial distributions of oilseed rape fields influence the abundance and the body size of a solitary wild bee, Andrena cineraria, in permanent grasslands.

open access: yesPLoS ONE, 2018
Wild bees are essential pollinators whose survival partly depends on the capacity of their environment to offer a sufficient amount of nectar and pollen.

Oilseed rape and bronchial reactivity. [PDF]

open access: yesOccupational and Environmental Medicine, 1995
OBJECTIVES--To investigate atopy and changes in symptoms, peak flow rate, and bronchial reactivity in people complaining of symptoms during the oilseed rape flowering season. METHODS--37 people who had given positive answers to questions about the presence of symptoms in relation to the flowering season of oilseed rape and 24 controls with no such ...

Enhancing the Secretion Systems: Genetic Engineering of Super Bioagents for Effective Plant Disease Control

open access: yesBiotechnology and Bioengineering, EarlyView.
Genetic engineering (GE) overcomes BCA limits, enabling robust, scalable crop protection. “Super Bioagents” (SBs) use optimized SSs to enhance bioactive molecule delivery. Optimizing SSs enhance precise, sustainable effector deployment for stable disease suppression. SBs use microbiome‐informed design for scalable, next‐gen sustainable crop protection.

Breeding for improved nitrogen use efficiency in oilseed rape [PDF]

open access: yes, 2008
Oilseed rape has a high requirement for nitrogen (N) fertiliser relative to its seed yield. This paper uses published and unpublished work to explore the extent to which the N use efficiency (seed yield ÷ N supply) of oilseed rape could be improved ...

Host‐associated genetic differentiation and origin of a recent host shift in the generalist parasitic weed Phelipanche ramosa

open access: yesEcology and Evolution, 2023
Branched broomrape, Phelipanche ramosa (L.) Pomel, is a globally distributed parasitic weed of economic importance. In Europe, where it is native, it can infest several crops, notably tomato, tobacco, and hemp.

Reconsidering how to dry orthodox seeds for improved ex situ conservation outcomes

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Ex situ seed conservation is an essential tool in our efforts to conserve wild and cultivated plant diversity, as mentioned in the Global Strategy for Plant Conservation and the Sustainable Development Goals. While there are established standards which seed banks follow, it is important that we continue to evaluate protocols and optimize processes ...

Zinc and phosphorus responses in transplanted oilseed rape (Brassica napus) [PDF]

open access: yes, 1996
Raising seedlings in a nursery and then transplanting them into the mainfield is a common practice for intensive cropping systems but the special nutrient requirements of the transplanted field crop have seldom been considered.

Advancing Sclerotinia risk forecasting for winter rapeseed in Germany: integrating crop phenology and disease development into a decision support system

open access: yesPest Management Science, EarlyView.
Integrating crop phenology and sclerotia germination models into SkleroPro improved Sclerotinia risk prediction accuracy from 34% to 66%, optimizing fungicide timing and supporting sustainable winter rapeseed production. Abstract BACKGROUND Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, threatens winter rapeseed (Brassica napus) production ...
