| Abstract | Sugar beet is the most important sugar crop in Morocco. The main production areas of sugar beet are Doukkala, Tadla, Gharb, and Moulouya. Rhizomania, caused by Beet necrotic yellow vein virus (BNYVV, genus Benyvirus), was first described in Italy and has spread in most sugar beet-growing areas of the world within a few decades. In the Tadla region, Rhizomania is one of the major phytosanitary problems for the sugar-beet industry. In 2010, five isolates from different locations in the Tadla region were collected for molecular characterization studies by sequencing the coat protein gene (CPg). The obtained results showed that all the sequenced isolates were in the B type of BNYVV and revealed the highest nucleotide similarity with the Belgian isolate B2 (AY696077), with a sequence homology of 100%. To the best of our knowledge, this is the first molecular characterization of BNYVV isolates in Morocco. Keywords: Rhizomania, sugar beet, molecular characterization, coat protein gene, Morocco. Caracterisation moleculaire du virus des nervures jaunes necrotiques de la betterave (BNYVV) infectant la betterave a sucre au Tadla Resume La betterave sucriere est la principale source de sucre au Maroc. Les principales zones de production de la betterave a sucre sont Doukkala, Tadla, Gharb, et Moulouya. La rhizomanie, causee par le virus des nervures jaunes necrotiques de la betterave (BNYVV, genre Benyvirus), a ete decrite pour la premiere fois en Italie et s’est propagee dans la plupart des regions productrices de la betterave sucriere. Dans la region de Tadla, la rhizomanie est l’un des principaux problemes phytosanitaires majeurs pour la culture de la betterave sucriere. En 2010, cinq isolats de differentes localites de la region de Tadla ont ete collectes pour des etudes de caracterisation moleculaire par le sequencage du gene de proteine de la capside (CP). Les resultats obtenus ont montre que les isolats marocains etaient dans le groupe B de BNYVV; ces isolats ont montre une grande similarite nucleotidique avec l’isolat Belge B2 (AY696077), avec une homologie de sequence de 100%. Au mieux de nos connaissances, il s’agit de la premiere caracterisation moleculaire des isolats de BNYVV au Maroc. Mots-cles: Rhizomanie, betterave sucriere, caracterisation moleculaire, gene de la proteine de la capside, Maroc. |
