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...
Publicado 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. longistaminata germplasm, we sought to quantify the population structure and diversity of this species across its geographic range, which includes most of sub-Saharan Africa, and to determine phylogenetic relationships to other AA-genome species of rice present in Africa, including the prevalence of interspecific hybridization between O. longistaminata and O. sativa. …”

Enriching rice grain zinc through zinc fertilization and water management
Publicado 2016“…Agronomic biofortification was not sufficient to meet rice Zn nutrition targets.Rice grain‐Zn concentration increased with more aerobic soil conditions.Fertilizer‐Zn applied to soil had limited effect on rice grain‐Zn concentration.Rice paddy water management affected soil redox potential and DTPA‐extractable Zn.Combined water and Zn management are useful for agronomic Zn biofortification.Agronomic biofortification was not sufficient to meet rice Zn nutrition targets.Increasing rice (Oryza sativa) grain‐Zn concentration is important for achieving improved human nutrition. …”

Soil fertility and indigenous nutrient supply in irrigated rice domains of Asia
Publicado 2003“…Knowledge‐intensive approaches have been proposed to manage the variability in indigenous nutrient supplies (IS) in irrigated rice (Oryza sativa L.) systems. On‐farm experiments were conducted at 155 locations in seven domains of Asia to quantify the variability of soil properties, grain yield, and nutrient uptake in N, P, and K omission plots (0‐N, 0‐P, and 0‐K, respectively). …”

Simultaneous biofortification of rice with zinc, iodine, iron and selenium through foliar treatment of a micronutrient cocktail in five countries
Publicado 2020“…Widespread malnutrition of zinc (Zn), iodine (I), iron (Fe) and selenium (Se), known as hidden hunger, represents a predominant cause of several health complications in human populations where rice (Oryza sativa L.) is the major staple food. Therefore, increasing concentrations of these micronutrients in rice grain represents a sustainable solution to hidden hunger. …”
