Phylogeography 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 کاملHistorical 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 کاملThe yellow fever situation in Africa.
WHILE THE TWENTIETH CENTURY HAS PRODUCED GREAT DEVELOPMENTS IN THE EPIDEMIOLOGY OF YELLOW FEVER AND IN TECHNIQUES FOR ITS CONTROL IN URBAN AREAS, THE ESSENTIAL METHOD OF CONTROL HAS NOT CHANGED: it is still the elimination of the urban vector, Aëdes aegypti. The aim of those responsible for yellow fever control in Africa should be the eradication of this vector from all urban communities in the...
متن کاملMutations in Rice yellow mottle virus Polyprotein P2a Involved in RYMV2 Gene Resistance Breakdown
Rice yellow mottle virus (RYMV) is one of the major diseases of rice in Africa. The high resistance of the Oryza glaberrima Tog7291 accession involves a null allele of the RYMV2 gene, whose ortholog in Arabidopsis, CPR5, is a transmembrane nucleoporin involved in effector-triggered immunity. To optimize field deployment of the RYMV2 gene and improve its durability, which is often a weak point i...
