Uromyces ciceris-arietini has been reported on Cicer arietinum (chickpea) and Medicago polyceratia. Plants of Medicago polymorpha in Riverside and San Diego, CA were collected with severe rust caused by U. ciceris-arietini. To confirm the identification and potential new host range, a monouredinial isolate of U. ciceris-arietini from M. polymorpha was inoculated on eight accessions each of C. arietinum and M. polyceratia. All plants showed symptoms of the disease. Consequently, a range of fabaceous hosts were evaluated for their reaction to U. ciceris-arietini. New hosts for U. ciceris-arietini included 29 species of Medicago, specifically M. arabica, M. blancheana, M. ciliaris, M. constricta, M. coronata, M. doliata, M. granadensis, M. intertexta, M. italica, M. laciniata, M. lanigera, M. lesinsii, M. lupulina, M. minima, M. murex, M. muricoleptis, M. orbicularis, M. praecox, M. radiata, M. rigidula, M. rotata, M. rugosa, M. sativa, M. sauvagei, M. scutellata, M. soleirolii, M. tenoreana, M. truncatula, and M. varia, and three species of Melilotus, specifically M. italicus, M. speciosus, and M. spicatus. This isolate of U. ciceris-arietini produced no symptoms on plants in the 33 accessions tested in the genera Anthyllis, Astragalus, Lotus, and Lupinus. DNA sequences are provided to aid in the identification of this pathogen.
鹰嘴豆单胞锈菌已在鹰嘴豆(鹰嘴豆)和多刺苜蓿上被报道。在加利福尼亚州河滨市和圣地亚哥收集的多形苜蓿植株患有由鹰嘴豆单胞锈菌引起的严重锈病。为了确认鉴定结果和潜在的新寄主范围,将一株来自多形苜蓿的鹰嘴豆单胞锈菌单核分离株接种到8份鹰嘴豆和多刺苜蓿材料上。所有植株均表现出病害症状。因此,对一系列豆科寄主对鹰嘴豆单胞锈菌的反应进行了评估。鹰嘴豆单胞锈菌的新寄主包括29种苜蓿,具体为阿拉伯苜蓿、布兰奇苜蓿、睫毛苜蓿、缢缩苜蓿、冠状苜蓿、多荚苜蓿、格拉纳达苜蓿、互叶苜蓿、意大利苜蓿、条裂苜蓿、绵毛苜蓿、莱辛苜蓿、天蓝苜蓿、最小苜蓿、具刺苜蓿、短刺苜蓿、圆叶苜蓿、早熟苜蓿、辐射苜蓿、硬苜蓿、旋转苜蓿、皱叶苜蓿、紫花苜蓿、萨瓦热苜蓿、盾状苜蓿、铺散苜蓿、特诺雷苜蓿、截形苜蓿和变异苜蓿,以及3种草木犀,具体为意大利草木犀、美丽草木犀和穗状草木犀。在测试的33份扁蓿豆属、黄芪属、百脉根属和羽扇豆属材料上,该鹰嘴豆单胞锈菌分离株未在植株上产生症状。提供了DNA序列以帮助鉴定该病原体。
