A major gene for grain cadmium accumulation in oat (Avena sativa L.).
Cadmium (Cd) is a nonessential heavy metal that is highly toxic to living cells at very low concentrations. Most of the Cd in plants derives from soils. Owing to the large amounts consumed, cereals are the major source of dietary Cd, and Cd content in oat can exceed accepted limits. Plants have a set of mechanisms that control the uptake, accumulation, trafficking, and detoxification of Cd and ...
متن کاملA SNP genotyping array for hexaploid oat (Avena sativa L.)
Recognizing a need in cultivated hexaploid oat (Avena sativa L.) for a reliable set of reference SNPs, we have developed a 6K BeadChip design containing 257 Infinium I and 5,486 Infinium II Page 1 of 32 The Plant Genome Accepted paper, posted 06/19/2014. doi:10.3835/plantgenome2014.03.0010
متن کاملMechanisms of oat (Avena sativa L.) acclimation to phosphate deficiency
Background Deficiency of available forms of phosphorus is common in most soils and causes reduction of crop plants growth and yield. Recently, model plants responses to phosphate (Pi) deficiency have been intensively studied. However, acclimation mechanisms of cereals like oat (Avena sativa L.), to low Pi stress remains not fully understood. Oat plants have been usually cultured on poor soils, ...
متن کاملTransferability and utility of white oat (Avena sativa) microsatellite markers for genetic studies in black oat (Avena strigosa).
Preservation and use of wild oat species germplasm are essential for further improvement of cultivated oats. We analyzed the transferability and utility of cultivated (white) oat Avena sativa (AACCDD genome) microsatellite markers for genetic studies of black oat A. strigosa (A(s)A(s) genome) genotypes. The DNA of each black oat genotype was extracted from young leaves and amplified by PCR usin...
متن کاملCarbon partitioning between oil and carbohydrates in developing oat (Avena sativa L.) seeds
Cereals accumulate starch in the endosperm as their major energy reserve in the grain. In most cereals the embryo, scutellum, and aleurone layer are high in oil, but these tissues constitute a very small part of the total seed weight. However, in oat (Avena sativa L.) most of the oil in kernels is deposited in the same endosperm cells that accumulate starch. Thus oat endosperm is a desirable mo...
