Abstract

Abstract: Rapid advances in genomics are providing the tools to determine the genetic basis of quality (both nutritional and functional) in cereals. This promises to allow increased rates of genetic gain in breeding by reducing the need for extensive end-product testing of new varieties. Many quality traits are the result of relatively recent human selection and are thus likely to be controlled by only a few major genes. This makes identification of these genes for use in breeding selection an attractive target for breeders. Examples of the discovery of genes that are major contributors to key grain quality attributes include, fragrance and cooking temperature in rice (identified by re-sequencing) and loaf volume and milling yield in wheat (identified by transcriptome analysis). Extension of genomic tools to an analysis of the wider gene pool including wild relatives will enable the identification of alleles that may contribute to improved or novel grain quality in the future and may be critical to ensuring quality is retained in a changed climate. Completely new cereal species might be produced.

谷物品质基因组学

摘要：基因组学的快速发展为确定谷物质量（包括营养和功能）的遗传基础提供了工具。这有望通过减少对新品种进行广泛最终产品测试的需求，提高育种中的遗传增益率。许多品质性状是相对较新的人类选择的结果，因此可能只受少数主要基因的控制。这使得鉴定这些基因用于育种选择成为育种家的一个有吸引力的目标。发现对关键谷物品质属性有主要贡献的基因的例子包括水稻的香味和烹饪温度（通过重新测序确定）以及小麦的面包体积和碾磨产量（通过转录组分析确定）。将基因组工具扩展到对更广泛的基因库（包括野生亲缘关系）的分析，将有助于识别未来可能有助于改善或新的粮食质量的等位基因，并可能对确保在气候变化中保持质量至关重要。可能会产生全新的谷物品种。

期刊介绍： The CBAB – CROP BREEDING AND APPLIED BIOTECHNOLOGY (ISSN 1984-7033) – is the official quarterly journal of the Brazilian Society of Plant Breeding, abbreviated CROP BREED APPL BIOTECHNOL. It publishes original scientific articles, which contribute to the scientific and technological development of plant breeding and agriculture. Articles should be to do with basic and applied research on improvement of perennial and annual plants, within the fields of genetics, conservation of germplasm, biotechnology, genomics, cytogenetics, experimental statistics, seeds, food quality, biotic and abiotic stress, and correlated areas. The article must be unpublished. Simultaneous submitting to another periodical is ruled out. Authors are held solely responsible for the opinions and ideas expressed, which do not necessarily reflect the view of the Editorial board. However, the Editorial board reserves the right to suggest or ask for any modifications required. The journal adopts the Ithenticate software for identification of plagiarism.
