Comparisons of molecular diversity indices, selective sweeps and population structure of African rice with its wild progenitor and Asian rice

Autor: Ndjiondjop, M.N. Alachiotis, N. Pavlidis, P. Goungoulou, A. Kpeki, S.B. Zhao, D. Semagn, K.

Previous studies conducted on limited number of accessions have reported very low genetic variation in African rice (Oryza glaberrima Steud.) as compared to its wild progenitor (O. barthii A. Chev.) and to Asian rice (O. sativa L.). Here, we characterized a large collection of African rice and co...

Assessment of Genetic Variation and Population Structure of Diverse Rice Genotypes Adapted to Lowland and Upland Ecologies in Africa Using SNPs

Autor: Ndjiondjop, M.N. Semagn, K. Sow, M. Manneh, B. Gouda, A.C. Kpeki, S.B. Pegalepo, E. Wambugu, P. Sié, M. Warburton, M.L.

Using interspecific crosses involving Oryza glaberrima Steud. as donor and O. sativa L. as recurrent parents, rice breeders at the Africa Rice Center developed several 'New Rice for Africa (NERICA)' improved varieties. A smaller number of interspecific and intraspecific varieties have also been r...

Development of species diagnostic SNP markers for quality control genotyping in four rice (Oryza L.) species

Autor: Ndjiondjop, M.N. Semagn, K. Zhang, J. Gouda, A.C. Kpeki, S.B. Goungoulou, A. Wambugu, P. Dramé, K.N. Bimpong, I.K. Zhao, D.

Species misclassification (misidentification) and handling errors have been frequently reported in various plant species conserved at diverse gene banks, which could restrict use of germplasm for correct purpose. The objectives of the present study were to (i) determine the extent of genotyping e...

Screening African Rice (Oryza glaberrima) for Tolerance to Abiotic Stresses: II. Lowland Drought

Autor: Shaibu, A.A. Uguru, M.I. Sow, M. Maji, A.T. Ndjiondjop, M.N. Venuprasad, R.

Drought is a major constraint to rice (Oryza spp.) production in sub-Saharan Africa. Oryza glaberrima Steud., the cultivated rice species that originated from West Africa, is well-adapted to its growing ecologies. This study was initiated to identify promising O. glaberrima accessions tolerant to...

Evaluation of rice cultivars for resistance to rice yellow mottle virus

Autor: Kam, H. Ndjiondjop, M.N. Ouedraogo, N. Laing, M.D. Ghesquière, Alain

Rice yellow mottle virus (RYMV), which is only found in Africa, threatens rice farming on the continent. A local Oryza sativa cultivar collected from Burkina Faso (named BM24), was evaluated with that of well known highly resistant and tolerant cultivars. Firstly, three RYMV isolates were used to...

Evolutionary Relationships Among the Oryza Species

Autor: Wambugu P.W. Nyamongo D. Ndjiondjop, M.N. Henry R.J.

Despite being highly studied, the evolutionary relationships in the Oryza genus have remained inconsistent and inconclusive. The origin and domestication history of Asian rice has particularly remained contentious. This chapter discusses the evolutionary relationships between various species in t...

Genetic control of seed shattering during African rice domestication.

Domestication represents a unique opportunity to study the evolutionary process. The elimination of seed dispersal traits was a key step in the evolution of cereal crops under domestication. Here, we show that ObSH3, a YABBY transcription factor, is required for the development of the seed abscis...
