Resistance to Sclerotinia sclerotiorum in wild Brassica species and the importance of Sclerotinia subarctica as a Brassica pathogen

plant_pathology_jun17.jpgA Taylor, K Rana, C Handy, JP Clarkson

Brassica crops are of global importance with oilseed rape (Brassica napus) accounting for 13% of edible oil production. All Brassica are susceptible to Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, a generalist fungal pathogen causing disease in over 400 plant species. This is the first study to identify B. cretica as a source of resistance to S. sclerotiorum and to report resistance in other wild Brassica species to a UK isolate, hence providing resources for breeding of resistant cultivars suitable for Europe.

Research on integrated pest and disease management in carrot crops

1153aR.H Collier, D. Wilson, A. Jukes, M.S. Elliott, R. Warmington and J. Clarkson

The paper describes research on integrated pest and disease management in carrot crops, focusing on treatment timings for control of Psila rosae with a relatively new insecticide, Coragen®, the development of a forecast of the timing of the migration of Cavariella aegopodii into carrot crops and the use of biofumigation for control of soilborne plant pathogens such as Sclerotinia sclerotiorum. All three approaches show promise as components of integrated pest and disease management programmes.

Development of a Statistical Crop Model to Explain the Relationship between Seed Yield and Phenotypic Diversity within the Brassica napus Genepool

Plants are extremely versatile organisms that respond to the environment in which they find themselves, but a large part of their development is under genetic regulation. The links between developmental parameters and yield are poorly understood in oilseed rape; understanding this relationship will help growers to predict their yields more accurately and breeders to focus on traits that may lead to yield improvements. Assessing the diversity that exists within the B. napus gene pool has highlighted architectural, seed and mineral composition traits that should be targeted in breeding programmes through the development of linked markers to improve crop yields.

Eukaryotic translation initiation factor 2B-beta (eIF2Bβ), a new class of plant virus resistance gene

Plant Journal feb17Shopan Jannat, Haipeng Mou, Lili Zhang, Changtong Zhang, Weiwei Ma, John A. Walsh, Zhongyuan Hu, Jinghua Yang, Mingfang Zhang

Recessive resistances to plant viruses in the Potyvirus genus have been found to be based on mutations in the plant eukaryotic translation initiation factors, eIF4E and eIF4G or their isoforms. Here we report that natural, monogenic recessive resistance to the potyvirus Turnip mosaic virus (TuMV) has been found in a number of mustard (Brassica juncea) accessions. Our findings provide a new target for seeking natural resistance to potyviruses and new opportunities for the control of potyviruses using genome editing techniques targeted on eIF2Bβ.

Plant Disease feb17First report of sclerotinia subarctica nom. prov. (Sclerotinia sp. 1) causing stem rot on turnip rape (Brassica rapa subsp. oleifera) in Norway

Brodal G, Warmington R, Grieu C, Ficke A, Clarkson JP

During August 2013, white-grayish lesions, typical of Sclerotinia stem rot, had developed around leaf axils on the stems of turnip rape ‘Pepita’ in a field at the NIBIO research station Apelsvoll in Oppland County, Norway. Sclerotina were collected from inside infected turnip rape stubble and from harvested seeds, surface sterilized, bisected, and placed onto potato dextrose agar (PDA). Although S. subarctica has been previously reported on wild hosts, this is the first report of the pathogen on a crop plant in Norway.

Plant Disease feb17First report of Fusarium oxysporum causing a vascular wilt of statice (Limonium sinuatum) in the UK

Taylor, Andrew, Sims, Isabel, Jackson, Alison C. and Clarkson, John P

Statice (Limonium sinuatum) is grown commercially in many countries as a cut-flower crop. Fungal and oomycete pathogens reported for this plant include Colletotrichum, Botrytis, Cercospora, Rhizoctonia, and Peronospora (Moorman 2016). In the UK, 80% of all statice production (2.5 ha, value $800,000) is through a specialist grower in Lincolnshire. To our knowledge, this is the first report of Fusarium wilt of statice. Further work is required to establish the host range of this potentially new forma specialis.

Who is sowing our seeds? A systematic review of the use of plant genetic resources in research

Genetic Resources and Crop EvolutionL. R. Davies; C. J. Allender

Collections of plant genetic resources managed by genebanks function to conserve the range of genetic diversity present in crop genepools. They can facilitate access to valuable allelic variation for both plant breeders and researchers who are able to request germplasm for use in crop improvement and both basic and applied scientific research. The direct impact of genebank collections is often unclear as downstream uses of germplasm samples may not be reported back to the genebank of origin.
This study aims to systematically review scientific use of germplasm using the UK Vegetable Genebank (UKVGB) as a model.
