Assessing Quantitative Resistance against Leptosphaeria maculans (Phoma Stem Canker) in Brassica napus (Oilseed Rape) in Young Plants
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 stem. By using doubled haploid (DH) lines A30 (susceptible) and C119 (with quantitative resistance), quantitative resistance against L. maculans...
متن کاملEffects of Leptosphaeria maculans race structure and fitness cost of virulence on management of phoma stem canker in oilseed rape
Fitness of virulent (avrLm1 and avrLm4) or avirulent (AvrLm1 and AvrLm4) isolates of Leptosphaeria maculans on Brassica napus without the corresponding resistance genes Rlm1 and Rlm4 was investigated in controlled environment (CE) and field experiments. Results indicate that there is a measurable fitness cost for virulent isolates compared to avirulent isolates in terms of number of lesions, si...
متن کاملRelative levels of resistance to bacterial canker in Iranian apricot hybrids
Mohammadi R, Keshavarzi M, Hassanzadeh N, Dejampour J, Farhadnejad A (2021) Relative resistance levels to bacterial canker in Iranian apricot hybrids. Plant Pathology Science 10(2):15-29. Doi: 10.2982/PPS.10.2.15. Introduction: Bacterial canker caused by Pseudomonas syringae is one of the most damaging diseases in apricots. This experiment was conducted to evaluate relative resist...
متن کاملComparative genomic analysis of duplicated homoeologous regions involved in the resistance of Brassica napus to stem canker
All crop species are current or ancient polyploids. Following whole genome duplication, structural and functional modifications result in differential gene content or regulation in the duplicated regions, which can play a fundamental role in the diversification of genes underlying complex traits. We have investigated this issue in Brassica napus, a species with a highly duplicated genome, with ...
متن کاملQuantitative PCR method for diagnosis of citrus bacterial canker.
For diagnosis of citrus bacterial canker by PCR, an internal standard is employed to ensure the quality of the DNA extraction and that proper requisites exist for the amplification reaction. The ratio of PCR products from the internal standard and bacterial target is used to estimate the initial bacterial concentration in citrus tissues with lesions.
