Mitochondrial genome of African rice (Oryza glaberrima): comparative analysis and phylogenetic relationships [PDF]

Mitochondrial DNA. Part B. Resources
We report the first complete mitochondrial genome of African rice (Oryza glaberrima), spanning 376,795 bp across two circular chromosomes (GC: 43.9%) and encoding 65 genes (39 protein-coding, 21 tRNA, 5 rRNA).

Development of a SNP genotyping panel for detecting polymorphisms in Oryza glaberrima/O. sativa interspecific crosses

Euphytica, 2014
Oryza glaberrima accessions harbor genes for tolerance to abiotic stresses such as mineral deficiency in problem soils. This genetic potential could be exploited in interspecific crosses with Oryza sativa, as in the case of the ‘New Rice for Africa’ (NERICA) varieties; however, to attain this goal it would be desirable to develop a high-throughput ...

The FORGENIUS Genomic Resources: New Genotyping Tools and Genomic Data for 23 Forest Tree Species and Their Genetic Conservation Units. [PDF]

Mol Ecol Resour
ABSTRACT Genetic diversity is a critical but often overlooked component of biological diversity. The European H2020 FORGENIUS project is aimed at increasing the quality and quantity of genetic data to start monitoring the European network of forest Genetic Conservation Units (GCUs).

Deepwater response in the African cultivated rice Oryza glaberrima

Plant Production Science, 2023
Partial submergence of Oryza sativa deepwater rice elicits enhancement of internodal elongation, referred to as deepwater response, conferred by three types of genes, SNORKEL1/2 (SK1/2), SEMIDWARF1 (SD1), and ACCELERATOR OF INTERNODE ELONGATION 1 (ACE1).

Resistance of and Genotypes to RBe24 Isolate of Rice Yellow Mottle Virus in Benin and Effects of Silicon on Host Response [PDF]

The Plant Pathology Journal, 2021
Rice yellow mottle virus (RYMV) is the most harmful virus that affects irrigated and lowland rice in Africa. The RBe24 isolate of the virus is the most pathogenic strain in Benin.

Histopathology of the rice root-knot nematode, Meloidogyne graminicola, on Oryza sativa and O. glaberrima [PDF]

Nematology, 2014
The root-knot nematode,Meloidogyne graminicola, can cause substantial rice yield losses. Understanding the mechanisms of resistance to this nematode species in known resistant rice genotypes may help to improve rice genotypes, aiming at developing and implementing environment-friendly and cost-effective nematode management strategies. Using susceptible

Genetic diversity of the two cultivated rice species (O. sativa & O. glaberrima) in Maritime Guinea. Evidence for interspecific recombination [PDF]

Euphytica, 2007
In Maritime Guinea, the interpenetration of upland, lowland and mangrove rice growing ecosystems has found expression in the cohabitation of the two rice cultivated species. Recent changes in cropping practices may lead to the replacement of local varieties by modern high-yielding varieties.

Genetic diversity of improved varieties of intraspecific (O. sativa and O. glaberrima) and interspecific (O. sativa × O. glaberrima) rice

Genetic Resources and Crop Evolution, 2017
Information on genotype diversity and interrelationships is essential for germplasm management, crop improvement and seed production. In this study the diversity of a collection of 36 rice accessions comprising of Oryza sativa L., O. glaberrima Steud. and interspecific rice (O. sativa × O.

Suppression of cell wall-related genes associated with stunting of Oryza glaberrima infected with Rice tungro spherical virus

Frontiers in Microbiology, 2014
Rice tungro disease is a complex disease caused by the interaction between Rice tungro bacilliform virus and Rice tungro spherical virus (RTSV). RTSV alone does not cause recognizable symptoms in most Asian rice (Oryza sativa) plants, whereas some ...

Differences in meristem size and expression of branching genes are associated with variation in panicle phenotype in wild and domesticated African rice

EvoDevo, 2017
Background The African rice Oryza glaberrima was domesticated from its wild relative Oryza barthii about 3000 years ago. During the domestication process, panicle complexity changed from a panicle with low complexity in O.
