摘要

摘要:本研究的目的是绘制巴西南部水稻籽粒铁积累的染色体区域。对81份水稻材料进行了铁积累的基因分型和表型分析。在全谷物的1、5、6和10号染色体上定位了单核苷酸多态性，从中鉴定出13个候选基因。其中一些基因，如O s10g0406800，似乎与铁稳态有关，而其他基因则与其他代谢过程有关或具有未知的功能。

Genome-wide association of iron content in rice grains grown in Southern Brazil

Abstract The objective of this work was to map the chromosomal regions responsible for iron accumulation in rice grains, in Southern Brazil. Eighty-one rice accessions were genotyped and phenotyped for Fe accumulation. Single nucleotide polymorphisms were mapped in the whole grain on chromosomes 1, 5, 6, and 10, from which 13 candidate genes were identified. Some of the genes, such as O s10g040680 0, seem to have a relationship with Fe homeostasis, while others are related to other metabolic processes or have an unknown function.
