Origins and geographic diversification of African rice (Oryza glaberrima). [PDF]
PLoS ONE, 2019 Rice is a staple food for the majority of the world's population. Whereas Asian rice (Oryza sativa) has been extensively studied, the exact origins of African rice (Oryza glaberrima) are still contested.

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).

The genome sequence of African rice (Oryza glaberrima) and evidence for independent domestication [PDF]
Nature Genetics, 2014 The cultivation of rice in Africa dates back more than 3,000 years. Interestingly, African rice is not of the same origin as Asian rice (Oryza sativa L.) but rather is an entirely different species (i.e., Oryza glaberrima Steud.). Here we present a high-quality assembly and annotation of the O.

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 ...

Differential Salinity Tolerance among Oryza glaberrima, Oryza sativa and Their Interspecies Including NERICA [PDF]
Plant Production Science, 2010 Salinity tolerance has been extensively studied in Oryza sativa, but little is known about the salt tolerance levels in Oryza glaberrima and the interspecific progenies including New Rice for Africa (NERICA).

Genetic Variation and Population Structure of Oryza glaberrima and Development of a Mini-Core Collection Using DArTseq [PDF]
Frontiers in Plant Science, 2017 The sequence variation present in accessions conserved in genebanks can best be used in plant improvement when it is properly characterized and published. Using low cost and high density single nucleotide polymorphism (SNP) assays, the genetic diversity,

Birth and death evolution of polyphenol oxidase (PPO) gene family in Oryza species [PDF]
Botanical StudiesBackground Polyphenol oxidases (PPOs) are copper-containing enzymes that catalyze the oxidation of phenolic substrates to quinones. In cereal crops, PPOs contribute to both grain browning and defense responses.

Morpho-Physiological Response of Oryza glaberrima to Gradual Soil Drying
Rice Science, 2020 Soil drought occurrence during dry season has been the main constraint, besides prolonged flooding during rainy season, in increasing cropping intensity and rice productivity in tropical riparian wetland.
