从野草到人类主粮之一,小麦在被驯化的过程中发生了巨大变化。一个国际科研小组对野生小麦进行基因测序,发现了控制穗轴易碎性的两组基因,它们在小麦驯化过程中起着关键作用。这一发现有助于培育更好的小麦品种。位于今天中东地区被称作“新月沃地”的区域,是小麦的起源地。大约1万年前,这里的居民开始种
From weeds to one of the staple foods of humanity, tremendous changes have taken place in the domestication of wheat.

This finding helps to cultivate better wheat varieties. Located in today’s Middle East is called “crescent fertile land” area, is the birthplace of wheat. About 10,000 years ago, residents here began to grow
