Mutations 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...
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 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 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 کاملIntegration of Molecular Markers in Rice Improvement: A Case Study on Resistance to Rice yellow mottle virus
(eds M.C.S. Wopereis et al.) 161 to be limited in comparison with the number of publications that report genetic linkage between markers and genes of interest. This may be explained by the delay observed in the theoretical development of a methodology and its practical outputs or absence of information on the methodology used (Collard and Mackill, 2008). Van Damme et al. (2011) hypothesize that...
