Challenges and prospects in using biotechnological interventions in O. glaberrima, an African cultivated rice [PDF]
GM Crops and Food, 2022 Africa has the world’s fastest rate of population expansion, making it vulnerable to food shortages. Africa cultivates two types of rice (Asian rice; Oryza sativa and African rice; Oryza glaberrima). Native African rice called O.

Mapping QTL hotspots associated with weed competitive traits in backcross population derived from Oryza sativa L. and O. glaberrima Steud. [PDF]
Scientific Reports, 2020 To improve grain yield under direct seeded and aerobic conditions, weed competitive ability of a rice genotype is a key desirable trait. Hence, understanding and dissecting weed competitive associated traits at both morphological and molecular level is ...

Independent Origin of Phenol Non-responsive Phenotype Caused By Phr1 Variation During Domestication of Asian and African Rice [PDF]
RicePhenol color reaction has been used to distinguish between two subspecies of Asian rice (Oryza sativa), indica and japonica. The trait is controlled by one single Phr1 gene, which encodes a PPO enzyme that catalyzes the oxidation of phenolic compounds ...

Improving bridge effect to overcome interspecific hybrid sterility by pyramiding hybrid sterile loci from Oryza glaberrima [PDF]
Scientific Reports, 2023 In order to evaluate the genetic effect caused by hybrid sterile loci, NILs with O. glaberrima fragment at six hybrid sterile loci under O. sativa genetic background (single-locus-NILs) were developed; two lines harboring two hybrid sterile loci, one ...

Contrasting physiological responses by cultivars of Oryza sativa and O. glaberrima to prolonged submergence. [PDF]
Ann Bot, 2009 Oryza glaberrima is widely grown in flood-prone areas of African river basins and is subject to prolonged periods of annual submergence. The effects of submergence on shoot elongation, shoot biomass, leaf area and CO(2) uptake were studied and compared with those of O. sativa.A wide selection of lines of O. sativa and O.

Mapping three new interspecific hybrid sterile loci between Oryza sativa and O. glaberrima. [PDF]
Breed Sci, 2014 Hybrid sterility hinders the transfer of useful traits between Oryza sativa and O. glaberrima. In order to further understand the nature of interspecific hybrid sterility between these two species, a strategy of multi-donors was used to elucidate the range of interspecific hybrid sterility in this study. Fifty-nine accessions of O. glaberrima were used

Genomic introgressions from African rice (Oryza glaberrima) in Asian rice (O. sativa) lead to the identification of key QTLs for panicle architecture [PDF]
BMC Genomics, 2023 Background Developing high yielding varieties is a major challenge for breeders tackling the challenges of climate change in agriculture. The panicle (inflorescence) architecture of rice is one of the key components of yield potential and displays high ...

Solving the mystery of Obake rice in Africa: population structure analyses of Oryza longistaminata reveal three genetic groups and evidence of both recent and ancient introgression with O. sativa [PDF]
Frontiers in Plant Science, 2023 The undomesticated rice relative Oryza longistaminata is a valuable genetic resource for the improvement of the domesticated Asian rice, Oryza sativa. To facilitate the conservation, management, and use of O.
