Historical Contingencies Modulate the Adaptability of Rice Yellow Mottle Virus
The rymv1-2 and rymv1-3 alleles of the RYMV1 resistance to Rice yellow mottle virus (RYMV), coded by an eIF(iso)4G1 gene, occur in a few cultivars of the Asiatic (Oryza sativa) and African (O. glaberrima) rice species, respectively. The most salient feature of the resistance breaking (RB) process is the converse genetic barrier to rymv1-2 and rymv1-3 resistance breakdown. This specificity is mo...
متن کاملPhylogeography of Rice yellow mottle virus in Africa.
The sequences of the coat protein gene of a representative sample of 40 isolates of Rice yellow mottle virus (RYMV) from 11 African countries were analysed. The overall level of nucleotide diversity was high (approximately 14%). Great geographical distances between the sites where isolates were collected were consistently associated with high genetic distances. In contrast, a wide range of gene...
متن کاملMaternal genetic effect of resistance to rice yellow mottle virus disease in rice
Reciprocal selection is a breeding procedure for population improvement and hybrid development. Both female and male parents contribute genes to their offspring, but the influence of female parent often extends beyond simple genetic transmission. Nine parents were crossed in a full diallel and evaluated for maternal genetic effects for resistance to rice yellow mottle virus disease. This study ...
متن کاملInternal point mutations of the capsid modify the serotype of Rice yellow mottle virus.
Rice yellow mottle virus is classified in five major serotypes; the molecular diversity of the coat protein (CP) is well established, but the amino acids involved in the recognition by discriminant monoclonal antibodies (MAbs) remain unknown. Reconstruction of a phylogenetic tree and sequence alignment of the CP gene of a sample representative of the continental-large diversity were used to ide...
متن کاملMovement of rice yellow mottle virus between xylem cells through pit membranes.
The translocation of rice yellow mottle virus (RYMV) within tissues of inoculated and systemically infected Oryza sativa L. leaves was characterized by Western immunoblotting, Northern blotting, and electron microscopy of thin sections. In inoculated leaves, RYMV RNA and coat protein first were detected at 3 and 5 days postinoculation, respectively. By 6 days postinoculation, RYMV had spread sy...
