摘要

谷胱甘肽s -转移酶(GSTs)是植物合成的蛋白质，负责植物对环境胁迫的耐受性。然而，关于甘薯这种全球重要作物的GST基因家族的信息很少。甘薯GSTs的遗传进化尚不清楚。本研究通过转录组学和比较基因组学分析对甘薯GST基因家族进行了研究。总共确定了51个商品及服务税。基因表达分析显示两个被调查品种间GSTs的表达模式存在差异。在氧化胁迫、盐胁迫和干旱胁迫下，部分GST表达水平或上调或下调。该研究结果为甘薯GST基因家族的研究提供了新的思路，有助于进一步了解这些基因在调控非生物胁迫中的作用。

Role of sweet potato GST genes in abiotic stress tolerance revealed by genomic and transcriptomic analyses

Glutathione S-transferases (GSTs) are proteins synthesized in plants and responsible for their tolerance to environmental stresses. However, little information is available on the GST gene family of sweet potato, a globally important crop. The genetic evolution of GSTs in sweet potato remains unclear. The present study investigated the GST gene family in sweet potato by transcriptomic and comparative genomic analyses. A total of 51 GSTs were identified. Gene expression analysis showed differential expression patterns of the GSTs between two investigated varieties. Some GST expression levels were either upor downregulated under oxidative, salinity and drought stresses. The results of the investigation provided new insights on the GST gene family in sweet potato, which may further the understanding of the roles of these genes in regulating abiotic stresses.

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 The article must be unpublished.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.
