柑橘黄单胞菌Fuscanans(Xcf)和菜豆黄单胞菌(Xanthomonas phaseoli PV.)菜豆白粉病(Phaseoli，XPP)是引起菜豆白叶枯病(CBB)的主要病原，是世界范围内难以控制的一种重要病害。这些病原菌在黄单胞菌属内属于不同的种类，经历了一个动态的进化历史，包括编码可能与菜豆适应和致病有关的基因的水平转移。种子传播是CBB疾病循环的一个关键点，有利于病原体的垂直传播和通过全球种子贸易在世界范围内传播疾病。界：细菌；门：变形杆菌；纲：变形杆菌；目：溶菌目(又称黄单胞菌目)；科：溶菌科(也称为黄单胞菌科)；属：黄单胞菌；种：柑橘黄单胞菌。Fuscanans和菜豆X.phaseoli PV.菜籽油(XCF-XPP)。XCF-Xpp的主要寄主是菜豆。菜豆(Phaseolus Luatus)和Vigna属成员(Vigna aconitifolia、Vigna angularis、Vigna Mungo、Vigna Radiata和Vigna umellata)也是XCF-Xpp的自然宿主。据报道，XCF-Xpp在其他几种豆科植物中自然存在，如Calopogonium sp.、葛根、豌豆(Pisum Sativum)、紫斑豆(Lablab Purpureus)、大甲藻(Macroptilum Latrides)和花冠豆属(Strophyle Helvola)。关于四季豆(Phaseolus Acutifolius)和豌豆(Vigna unguulata subsp.)上自然发生的CBB制剂，有相互矛盾的报道。指甲藻)。CBB症状发生在豆类的所有地上部分，即幼苗、叶、茎、豆荚和种子。最初的症状表现为叶上被水浸泡的斑点演变为坏死，豆荚上有脓肿，树枝上有溃烂。在严重的感染中，可能会发生落叶和枯萎。CBB分布在世界各地，这意味着它在美洲、亚洲、非洲和大洋洲大多数种植豆类的地方经常发生，除了干旱的热带地区。XCF-XPP是欧洲受监管的非检疫病原体，被欧洲和地中海植物保护组织(EPPO)列入A2名单。基因组由一条环状染色体和一至四个大小不等的染色体外质粒组成，总平均大小为5.27亿Mb，GC含量为64.7%，平均预测编码序列数为4181个。CBB的管理以综合方法为基础，其中包括旨在避免通过受感染的种子引入XCF-XPP的措施、限制寄主作物之间XCF-XPP生存的栽培做法、尽可能使用耐受或抗病的豆类基因，以及主要限于铜化合物的化学处理。使用无病原体种子是有效管理战略的关键，需要适当的抽样、检测和鉴定方法。Https://gd.eppo.int/taxon/XANTPH，https://gd.eppo.int/taxon/XANTFF，和http://www.cost.eu/COST_Actions/ca/CA16107.本病原菌简介概述了目前对菜豆黄单胞菌的认识。Phaseoli和柑橘黄单胞菌(Xanthomonas Citri PV.)丝核菌，两组在系统发育上相距很远的菌株，它们能引起豆类常见的细菌枯萎病。
Xanthomonas citri pv. fuscans (Xcf) and Xanthomonas phaseoli pv. phaseoli (Xpp) are the causal agents of common bacterial blight of bean (CBB), an important disease worldwide that remains difficult to control. These pathogens belong to distinct species within the Xanthomonas genus and have undergone a dynamic evolutionary history including the horizontal transfer of genes encoding factors probably involved in adaptation to and pathogenicity on common bean. Seed transmission is a key point of the CBB disease cycle, favouring both vertical transmission of the pathogen and worldwide distribution of the disease through global seed trade. Kingdom: Bacteria; phylum: Proteobacteria; class: Gammaproteobacteria; order: Lysobacterales (also known as Xanthomonadales); family: Lysobacteraceae (also known as Xanthomonadaceae); genus: Xanthomonas; species: X. citri pv. fuscans and X. phaseoli pv. phaseoli (Xcf‐Xpp). The main host of Xcf‐Xpp is the common bean (Phaseolus vulgaris). Lima bean (Phaseolus lunatus) and members of the Vigna genus (Vigna aconitifolia, Vigna angularis, Vigna mungo, Vigna radiata, and Vigna umbellata) are also natural hosts of Xcf‐Xpp. Natural occurrence of Xcf‐Xpp has been reported for a handful of other legumes such as Calopogonium sp., Pueraria sp., pea (Pisum sativum), Lablab purpureus, Macroptilium lathyroides, and Strophostyles helvola. There are conflicting reports concerning the natural occurrence of CBB agents on tepary bean (Phaseolus acutifolius) and cowpea (Vigna unguiculata subsp. unguiculata). CBB symptoms occur on all aerial parts of beans, that is, seedlings, leaves, stems, pods, and seeds. Symptoms initially appear as water‐soaked spots evolving into necrosis on leaves, pustules on pods, and cankers on twigs. In severe infections, defoliation and wilting may occur. CBB is distributed worldwide, meaning that it is frequently encountered in most places where bean is cultivated in the Americas, Asia, Africa, and Oceania, except for arid tropical areas. Xcf‐Xpp are regulated nonquarantine pathogens in Europe and are listed in the A2 list by the European and Mediterranean Plant Protection Organization (EPPO). The genome consists of a single circular chromosome plus one to four extrachromosomal plasmids of various sizes, for a total mean size of 5.27 Mb with 64.7% GC content and an average predicted number of 4,181 coding sequences. Management of CBB is based on integrated approaches that comprise measures aimed at avoiding Xcf‐Xpp introduction through infected seeds, cultural practices to limit Xcf‐Xpp survival between host crops, whenever possible the use of tolerant or resistant bean genotypes, and chemical treatments, mainly restricted to copper compounds. The use of pathogen‐free seeds is essential in an effective management strategy and requires appropriate sampling, detection, and identification methods. https://gd.eppo.int/taxon/XANTPH, https://gd.eppo.int/taxon/XANTFF, and http://www.cost.eu/COST_Actions/ca/CA16107. This pathogen profile summarizes the current knowledge on Xanthomonas phaseoli pv. phaseoli and Xanthomonas citri pv. fuscans, two phylogenetically distant groups of strains that cause common bacterial blight of bean.
