Determination of Aflatoxins and Selected Heavy Metals in Rice Varieties Cultivated in Fogera, Amhara Region, Ethiopia

Food Chemistry International, EarlyView.
ABSTRACT Rice (Oryza sativa L.) is a vital staple crop for nearly half the world's population. This study investigates the levels of aflatoxins (AFB1, AFB2, AFG1, and AFG2) and selected heavy metals (Cd, Pb, and Cr) and essential elements (Mn, Fe, Mg, Cu, and Zn) in rice varieties cultivated in Fogera, Amhara Region, Ethiopia.

Cross-species bacterial artificial chromosome (BAC) library screening via overgo-based hybridization and BAC-contig mapping of a yield enhancement quantitative trait locus (QTL) yld1.1 in the Malaysian wild rice Oryza rufipogon [PDF]

, 2005
The construction of BAC-contig physical maps is an important step towards a partial or ultimate genome sequence analysis. Here, we describe our initial efforts to apply an overgo approach to screen a BAC library of the Malaysian wild rice species, Oryza ...

An IRAT109 NAM population: Genetic characterization and mapping utility for trait dissection in japonica rice (Oryza sativa L.). [PDF]

Plant Genome
Abstract Complex agronomic traits in rice (Oryza sativa L.) are controlled by many genetic loci; however, dissection is often constrained in biparental mapping populations by limited recombination and narrow genetic diversity, and in diversity sets by spurious associations arising from cryptic relatedness.

Impact of high temperature processing and heating duration on fatty acid composition and trans fatty acid formation in seven cold‐pressed and five refined vegetable oils

Food Biomacromolecules, EarlyView.
Abstract Edible oils are essential dietary constituents that contribute as energy source, fatty acids and medium for fat‐soluble vitamins. High temperature during frying induces changes in the fatty acid profile of edible oils. The primary aim of this study is to investigate the influence of high temperature (230 ± 5°C) and duration of heating (0, 1, 2

Origin of rice (Oryza sativa L.) domestication genes [PDF]

Genetic Resources and Crop Evolution, 2017
A number of genes that contribute to the domestication traits of cultivated rice have been identified. These include Sh4, Rc, PROG1 and LABA1, which are associated with non-shattering rachis, white pericarp, erect growth and barbless awns, respectively.

The effect of awns on seed yield and germination characteristics in Elymus nutans Griseb.

Grassland Research, EarlyView.
The effect of awns on seed yield. Three‐year field trials demonstrated that awns significantly regulate seed yield components and germination characteristics of Elymus nutans Griseb, laying a theoretical foundation for the breeding of high‐yielding forage varieties and seed production.
