细菌性溃疡病是核果类水果的主要病害，是甜樱桃生产的重要限制因子。控制疾病的一个重要战略是开发抗病品种。甜樱桃的部分品种抗性是可辨别的使用拍摄或整棵树接种，然而，这些数量上的差异电阻在离体叶片测定是不明显的。为了确定新的抗溃疡病的来源，我们使用快速叶片致病性测试来筛选一系列野生樱桃、观赏李属物种和甜樱桃×观赏樱桃杂交种，这些野生樱桃、观赏李属物种和甜樱桃×观赏樱桃杂交种具有溃疡病病原体，假单胞菌（Pseudomonaseryningae）pvseryningae，morsprunorum小种1和2，以及禽流感。几个李加入表现出有限的症状发展接种后的每一种病原体，这种电阻扩展到16 P.甜樱桃和李致病的菌株。抗性与接种后细菌增殖减少有关，其表型类似于商业甜樱桃对非宿主菌株的P. pastingae。抗性观赏植物樱桃（Prunus incisa）与感病甜樱桃（P.avium）杂交产生的后代表现出抗性，表明其是遗传性状。鉴定对主要细菌性溃疡病病原体具有抗性的种质是表征抗性的潜在遗传机制并将这些性状引入商业种质的第一步。本研究采用离体叶片法鉴定李属植物对细菌性溃疡病的抗性。
Bacterial canker is a major disease of stone fruits and is a critical limiting factor to sweet cherry (Prunus avium) production worldwide. One important strategy for disease control is the development of resistant varieties. Partial varietal resistance in sweet cherry is discernible using shoot or whole tree inoculations; however, these quantitative differences in resistance are not evident in detached leaf assays. To identify novel sources of resistance to canker, we used a rapid leaf pathogenicity test to screen a range of wild cherry, ornamental Prunus species and sweet cherry × ornamental cherry hybrids with the canker pathogens, Pseudomonas syringae pvs syringae, morsprunorum races 1 and 2, and avii. Several Prunus accessions exhibited limited symptom development following inoculation with each of the pathogens, and this resistance extended to 16 P. syringae strains pathogenic on sweet cherry and plum. Resistance was associated with reduced bacterial multiplication after inoculation, a phenotype similar to that of commercial sweet cherry towards nonhost strains of P. syringae. Progeny resulting from a cross of a resistant ornamental species Prunus incisa with susceptible sweet cherry (P. avium) exhibited resistance indicating it is an inherited trait. Identification of accessions with resistance to the major bacterial canker pathogens is the first step towards characterizing the underlying genetic mechanisms of resistance and introducing these traits into commercial germplasm. This research paper identifies resistance towards Pseudomonas bacterial canker in Prunus species using detached leaf assays.
