Abstract

Comparative mapping is an important component of map-based cloning in large-genome cereal species. We describe evidence of a segmental chromosomal duplication harbouring CONSTANS-like genes in barley that predates the divergence of the Oryzoideae (rice) and Pooideae (brachypodium, barley, wheat) clades, and discuss the implications of such events for comparative mapping and QTL cloning in temperate cereal crops.

摘要

比较作图是大基因组谷类物种图谱定位克隆的重要组成部分。我们描述了大麦中含有 CONSTANS 样基因的片段性染色体重复的证据，该重复发生在 Oryzoideae（水稻）和 Pooideae（短柄草、大麦、小麦）分支分化之前，并讨论了此类事件对温带谷类作物比较作图和 QTL 克隆的影响。
