"Sequence diversity was examined in the coat protein (CP) gene of Groundnut rosette assistor virus (GRAV), the overlapping open reading frames (ORFs) 3 and 4 of Groundnut rosette virus (GRV), and the satellite RNA (sat-RNA) of GRV obtained from field isolates from Malawi and Nigeria. These three agents cause groundnut rosette disease, a major disease of groundnut in sub-Saharan Africa (SSA). Sequence analysis showed that the GRAV CP gene was highly conserved (97 to 99%) independent of its geographic source. The nucleotide sequence of the overlapping\r\nORFs 3 and 4 of GRV was highly conserved (98 to 100%) from\r\nisolates within a geographic region but less conserved (88 to 89%) between\r\nisolates from the two distinct geographic regions. Phylogenetic\r\nanalysis of the overlapping ORFs 3 and 4 show that the GRV isolates\r\ncluster according to the geographic region from which they were isolated,\r\nindicating that Malawian GRV isolates are distinct from Nigerian\r\nGRV isolates. Similarity within the sat-RNA sequences analyzed ranged\r\nfrom 88 to 99%. Phylogenetic analysis also showed clustering within the\r\nsat-RNA isolates according to country of origin, as well as within isolates\r\nfrom two distinct regions of Malawi. Because the GRAV CP sequence is\r\nhighly conserved, independent of the geographic source of the GRAV\r\nisolates, the GRAV CP sequence represents the most likely candidate to\r\nuse for pathogen-derived resistance in groundnut and may provide effective\r\nprotection against groundnut rosette disease throughout SSA."^^ .
