Abstract

Recent polyploidation of peanut genome and geographical isolation has rendered peanut to be a highly monomorphic species. Due to its narrow genetic base, cultivated peanut has been susceptible to various diseases, causing economic loss to farmers. Availability of only a few disease resistance sources in cultivated peanut has resulted in limited success using the conventional breeding practices. Also, scarcity of markers has been the major limiting factor to precisely identify the disease resistance genomic regions. Recentidentification of largenumber ofmolecular markers using advancedgenomic resources and high throughput sequencing technologies has and will continue to assist in improvement of peanut diversity and breeding. This review gives an update on recent discovery of molecular markers associated with major diseases and the available genomic resources in peanut.

花生抗病的分子标记和基因组资源综述

最近花生基因组的多倍化和地理隔离使花生成为一个高度单一的物种。由于其遗传基础狭窄，栽培花生易患各种疾病，给农民造成经济损失。由于栽培花生的抗病源很少，使用常规育种方法取得的成功有限。此外，标记物的缺乏一直是精确识别抗病基因组区域的主要限制因素。利用先进的基因组资源和高通量测序技术重新鉴定大量分子标记已经并将继续有助于改善花生的多样性和育种。本文综述了花生主要疾病相关分子标记的最新发现和可用的基因组资源。
