Identification of Race‐Specific, Clade‐Specific and Broad‐Spectrum Resistance to Xanthomonas campestris pv. campestris in Brassica Diversity Fixed Foundation Sets

Shannon F. Greer, Jamie Harrison, Daisy Bown, María‐Antonia Serrano et autres

ABSTRACT Black rot, caused by Xanthomonas campestris pv. campestris (Xcc), is the most damaging bacterial disease of vegetable brassicas ( Brassica oleracea ) worldwide. The prevalence of several genetically diverse Xcc races makes breeding for varietal resistance challenging. In this study, we …

Population genetics show that aphids (Hemiptera: Aphididae) are limited by summer host-plant distribution at the regional scale

Dion Garrett, Graham R. Teakle, ROSEMARY H. COLLIER, James R. Bell et autres

Nasonovia ribisnigri (Mosley) is a severe aphid pest of outdoor lettuce, and the combination of sporadic and unpredictable colonization on outdoor lettuce, along with the breakdown of cultivar resistance, has left few effective control methods. The population structure (spatially and temporally) of …

Evaluating antibiosis resistance to cabbage aphid ( Brevicoryne brassicae L ., 1758) in vegetable brassicas ( Brassica oleracea L .) and related C ‐genome brassica species

Andrew K Gladman, Gill Prince, Graham R. Teakle, David Chandler

BACKGROUND: Nineteen Brassica accessions from four C-genome species were screened under controlled environment conditions for their effects on the development of the cabbage aphid, Brevicoryne brassicae. The aim was to identify accessions with antibiosis host plant resistance (HPR) to B. brassicae. Candidate …

Genome assembly and transcriptomic analysis to elucidate the ability of Nasonovia ribisnigri to break host plant resistance

Dion Garrett, Graham R. Teakle, ROSEMARY H. COLLIER, James R. Bell et autres

Aphid genomic resources enable the study of complex life history traits and provide information on vector biology, host adaption and speciation. The currant-lettuce aphid (Nasonovia ribisnigri (Hemiptera: Aphididae) (Mosley)) is a cosmopolitan pest of outdoor lettuce (Lactuca sativa (Asterales: Asteraceae) (Linnaeus)). Until …

A review of sources of resistance to turnip yellows virus ( TuYV ) in Brassica species

Kyle Macleod, Shannon F. Greer, Lawrence E. Bramham, Ricardo José Gonzaga Pimenta et autres

Abstract Turnip yellows virus (TuYV; previously known as beet western yellows virus) causes major diseases of Brassica species worldwide resulting in severe yield‐losses in arable and vegetable crops. It has also been shown to reduce the quality of vegetables, particularly cabbage where …

Tipburn resilience in lettuce (Lactuca spp.) – the importance of germplasm resources and production system‐specific assays

Andrew M Beacham, Paul Hand, Graham R. Teakle, Guy C. Barker et autres

BACKGROUND: Tipburn is a physiological disorder of lettuce (Lactuca spp.). It causes discoloration and collapse of leaf margins, leading to unsaleable crops in both protected (glasshouse, hydroponic) and outdoor production systems. The occurrence of tipburn is hard to predict and is sensitive …

Unravelling effects of red/far-red light on nutritional quality and the role and mechanism in regulating lycopene synthesis in postharvest cherry tomatoes

Yanjie Song, Graham R. Teakle, Robert Lillywhite

The main goal of this study was to explore the role of red/far-red light in the preservation of postharvest quality in cherry tomato fruits and the mechanism of red/far-red light in regulation of lycopene synthesis. Results showed that red/far-red light irradiation inhibited …

Crop management shapes the diversity and activity of DNA and RNA viruses in the rhizosphere

George Muscatt, Sally L. Hilton, Sébastien Raguideau, Graham R. Teakle et autres

BACKGROUND: The rhizosphere is a hotspot for microbial activity and contributes to ecosystem services including plant health and biogeochemical cycling. The activity of microbial viruses, and their influence on plant-microbe interactions in the rhizosphere, remains undetermined. Given the impact of viruses on …
