摘　要：

番薯属(Ipomoea Linn.)是旋花科中物种最多的属, 其中多种植物因可作食物和药物来源以及观赏用途而广为栽培, 其中比较常见的植物包括牵牛花、甘薯、空心菜、茑萝等。该属植物既有二倍体也有多倍体。在基因组研究方兴未艾之际, 该属4个物种已有基因组草图, 它们是: 三浅裂野牵牛(I. trifida)、甘薯(I. batatas)、三裂叶薯(I. triloba)和牵牛花(I. nil)。本文简述了这些基因组研究的近况, 旨在为生物信息从业人员和广大致力于旋花科番薯属的科研人员提供最新信息和激励 更多的基因组测序合作计划。

Abstract:

Ipomoea is the largest genus of the Convolvulaceae family, with many species can be used for food and drug sources and ornamental purposes, including ordinary plants, such as morning glory, sweetpotato, water spinach, cypress vine and so on. In the wave of genome sequencing till nowadays, there are only four species in the genus Ipomoea have draft genome: they are I. trifida, I. batatas, I. triloba and I. nil. The purpose of this mini-review is to provide the latest information for bioinformatics practitioners and researchers or breeders who dedicate themselves to studying the genus Ipomoea, and may encourage more genome sequencing cooperation programs.
