Abstract

Cereals are prone to viral infections and the economic impact of these has increased in recent years. Among these diseases barley yellow dwarf (BYD) is one of the most destructive diseases of cereals today. For three consecutive years (2014–2015–2016) surveys were carried out in order to search for BYDV species (BYDV-PAV and -MAV) as well as other cereal viruses, wheat spindle streak mosaic virus (WSSMV), southern bean mosaic virus (SBMV) and barley stripe mosaic virus (BSMV) in seven regions of Algeria (Algiers, Boumerdes, Tipaza Médéa, Adrar, Khenchla and Batna).Targeted samples were taken randomly from plants of different cereal species (wheat, barley, oats). The sample were analyzed by DAS-ELISA and RT-PCR.The results of ELISA and PCR tests showed the presence of BYDV-PAV in barley, durum wheat, soft wheat and oats. Thus, this viral species were found in all the cereal regions surveyed (North, South, East and West).Seven samples (durum wheat, barley and oats) were sequenced and phylogenetic analyses performed revealed that the Algerian sequences clustered in group I and group II.

阿尔及利亚大麦黄矮病毒的发生及多样性

谷物容易受到病毒感染，其经济影响近年来有所增加。在这些病害中，大麦黄矮病是当今最具破坏性的谷物病害之一。2014-2015-2016年连续3年在阿尔及利亚7个地区(阿尔及尔、布默德斯、蒂帕扎·姆姆萨梅萨、阿德拉尔、肯奇拉和巴特纳)开展了BYDV (BYDV- pav和-MAV)以及其他谷物病毒、小麦纺轴条纹花叶病毒(WSSMV)、南豆花叶病毒(SBMV)和大麦条纹花叶病毒(BSMV)的调查。目标样本随机取自不同谷类植物(小麦、大麦、燕麦)。采用DAS-ELISA和RT-PCR对样品进行分析。ELISA和PCR检测结果表明，大麦、硬粒小麦、软质小麦和燕麦中均存在BYDV-PAV。因此，在所有调查的谷物区(北、南、东、西)都发现了该病毒种。对7个样品(硬粒小麦、大麦和燕麦)进行了测序，并进行了系统发育分析，结果显示阿尔及利亚序列聚集在类群I和类群II中。
