据央视网消息,由中国科学家领衔的研究团队,日前在国际上率先完成了小麦A基因组和D基因组的草图绘制,开启了全面破译小麦基因组的序幕。随着基因组学的发展,水稻和玉米的基因组相继被破译,但小麦基因组测序研究却一直困难重重。养活了全球40%人口的普通小麦是一个异源六倍体,由三个原始祖先物种两次天然杂交而来,含有A、B、D三个基因组。 According to CCTV news, the research team led by Chinese scientists recently took the lead in completing the sketches of A genome and D genome in wheat and opened the prelude to completely deciphering wheat genome. With the development of genomics, the genomes of rice and maize have been successively deciphered, but the research of wheat genome sequencing has been difficult. The common wheat, which feeds 40% of the world’s population, is a hexaploid, naturally crossed by two native ancestral species, containing three genomes, A, B and D.
