African rice (Oryza glaberrima): History and future potential [PDF]

Proceedings of the National Academy of Sciences, 2002
The African species of rice (Oryza glaberrima) was cultivated long before Europeans arrived in the continent. At present,O. glaberrimais being replaced by the introduced Asian species of rice,Oryza sativa. Some West African farmers, including the Jola of southern Senegal, still grow African rice for use in ritual contexts.

Evaluation of African Cultivated Rice Oryza glaberrima for Resistance to Bacterial Blight [PDF]

Plant Disease, 2011
Xanthomonas oryzae pv. oryzae is the causal agent of bacterial blight in rice, one of the most devastating diseases of rice worldwide. African X. oryzae pv. oryzae strains belong to a clear genetic group distinct from those of Asia. Three new races of the pathogen were characterized among strains from West Africa.

agReg-SNPdb-Plants: A Database of Regulatory SNPs for Agricultural Plant Species

Biology, 2022
Single nucleotide polymorphisms (SNPs) that are located in the promoter regions of genes and affect the binding of transcription factors (TFs) are called regulatory SNPs (rSNPs).

Assessment of morphological characteristics among upland rice (Oryza sativa and Oryza glaberrima) germplasm [PDF]

African Journal of Biotechnology, 2018
Rice is an important staple food crop that feeds over half of the global population and has become the cereal that provides a major source of calories for the urban and rural poor in Africa. This work aimed to evaluate the morphological of rice (Oryza sativa and Oryza glaberrima) germplasm.

A walk on the wild side: Oryza species as source for rice abiotic stress tolerance

Genetics and Molecular Biology, 2017
Oryza sativa, the common cultivated rice, is one of the most important crops for human consumption, but production is increasingly threatened by abiotic stresses. Although many efforts have resulted in breeding rice cultivars that are relatively tolerant

A Recessive Resistance to Rice yellow mottle virus Is Associated with a Rice Homolog of the CPR5 Gene, a Regulator of Active Defense Mechanisms

Molecular Plant-Microbe Interactions, 2013
RYMV2 is a major recessive resistance gene identified in cultivated African rice (Oryza glaberrima) which confers high resistance to the Rice yellow mottle virus (RYMV).

The Population Structure of African Cultivated Rice Oryza glaberrima (Steud.) [PDF]

Genetics, 2005
Abstract Genome-wide linkage disequilibrium (LD) was investigated for 198 accessions of Oryza glaberrima using 93 nuclear microsatellite markers. Significantly elevated levels of LD were detected, even among distantly located markers. Free recombination among loci at the population genetic level was shown (1) by a lack of decay in LD ...

PlantGFM: A Genomic Foundation Model for Discovery and Creation of Plant Genes

Advanced Science, EarlyView.
A plant genomic foundation model pre‐trained on 12 species enables both accurate gene prediction and de novo gene design. Through AI‐human knowledge screening, seven designed sequences showed transcriptional activity in plants, with two expressing stable proteins—demonstrating the first DNA‐RNA‐protein expression of LLM‐generated genes in plants and ...

Wide crossing diversify mitogenomes of rice

BMC Plant Biology, 2020
Background In most angiosperms, the inheritance of the mitochondria takes place in a typical maternal manner. However, very less information is available about if the existence of structural variations or not in mitochondrial genomes (mitogenomes ...
