Assessing quantitative resistance against Leptosphaeria maculans (phoma stem canker) in Brassica napus (oilseed rape) in young plants. [PDF]
PLoS ONE, 2014 Quantitative resistance against Leptosphaeria maculans in Brassica napus is difficult to assess in young plants due to the long period of symptomless growth of the pathogen from the appearance of leaf lesions to the appearance of canker symptoms on the ...

Experimental dissection of phenotypic variation for quantitative disease resistance in canola (Brassica napus) - Leptosphaeria maculans interactions. [PDF]
Pest Manag SciThis graphical abstract illustrates how quantitative resistance to Leptosphaeria maculans in canola is experimentally estimated through multi‐environment replicated trials measuring crown canker severity. Genotype, environment and pathogen sources feed into phenotyping, followed by variance partitioning using mixed models and beta regression to ...

Genome Sequence Resource of Xanthomonas citri pv. citri from Formalin-Fixed Citrus Leaves Specimen Showing Canker Lesions Collected in 1982 [PDF]
Plant Disease, 2022 Xanthomonas citri pv. citri is the causative agent of citrus canker, one of the most devastating diseases threatening global citrus production. Here, we present the genome sequence of X. citri pv. citri strain GD82 from a formalin-fixed citrus leaf specimen showing canker lesions collected in 1982 in Guangdong Province, China.

The epidemiology of the blackleg pathogen, Leptosphaeria maculans, impacts fungicide resistance management strategies. [PDF]
Pest Manag SciUnderstanding how infection timing drives disease is essential for the development of fungicide resistance management strategies. For blackleg disease of canola, all infection timings can contribute to the following generation, therefore all fungicide applications have the ability to select for resistance.

Deinococcus citri sp. nov., isolated from citrus leaf canker lesions
International Journal of Systematic and Evolutionary Microbiology, 2014 A Gram-stain-positive, strictly aerobic, non-motile, coccoid bacterium, designated NCCP-154T, was isolated from citrus leaf canker lesions and was subjected to a polyphasic taxonomic study. Strain NCCP-154T grew at 10–37 °C (optimum 30 °C) and at pH 7.0–8.0 (optimum pH 7.0). The novel strain exhibited tolerance of UV irradiation (>1000 J m−2). Based
