Unit and internal chain profile of African rice (Oryza glaberrima) amylopectin
Carbohydrate Polymers, 2016 High-performance anion-exchange chromatography was used to study the unit chain profiles of amylopectins and their φ,β-limit dextrins from two African rice (Oryza glaberrima) accessions-TOG 12440 and IRGC 103759. The samples were compared with two Asian rice (Oryza sativa) samples (cv Koshihikari and cv WITA 4) and one O. sativa × O.

Plant Breeding, EarlyView.ABSTRACT Global food demand is predicted to rise anywhere from 59% to 98% by 2050 because of increasing population. However, the continued depletion of natural resources and increasing biotic and abiotic stresses will continue to pose significant threats to global food security in coming years.

Challenges in Bringing Pangenome Research Into Breeding: A Case Study in Rice
Plant Biotechnology Journal, Volume 24, Issue 6, Page 3679-3690, June 2026.ABSTRACT Crop breeding has entered the pangenomics era, unlocking a far more comprehensive view of genetic diversity than a single reference genome can capture. In rice (Oryza sativa), a staple crop critical to global food security, the construction of pangenome resources has uncovered extensive structural variations (SVs), presence/absence variations (

Euphytica, 2015 Iron (Fe) toxicity is a major constraint in lowland rice. Because of its higher rusticity and adaptability to adverse soil conditions, the African rice Oryza glaberrima constitutes a new potential source of genes for rice improvement. This study aimed at mapping quantitative trait loci (QTLs) for resistance to Fe toxicity.

Molecular Control of Tiller Angle and Its Role in Rice Domestication
Food and Energy Security, Volume 15, Issue 3, May/June 2026.ABSTRACT Plant architecture is a key determinant of rice (Oryza sativa) productivity, with tiller angle playing a central role in optimizing plant density, light interception, and yield. During domestication, rice underwent a critical transition from the prostrate growth habit of wild relatives such as Oryza rufipogon to the erect architecture of ...

Transposable element distribution, abundance and role in genome size variation in the genus
BMC Evolutionary Biology, 2007 Background The genus Oryza is composed of 10 distinct genome types, 6 diploid and 4 polyploid, and includes the world's most important food crop – rice (Oryza sativa [AA]). Genome size variation in the Oryza is more than 3-fold and ranges from 357 Mbp in
