西藏野生小麦（Triticum aestivum var. tibetanum）是由3D染色体短臂上的一对显性基因控制的。新的脆轴基因被命名为Br-1。这项研究还发现，断节的类型是由许多基因，可能不同于脆轴基因。换句话说，同一个脆性脊柱基因可能在不同的遗传背景下表现出不同类型的断节。因此，粗山羊草的脆轴基因（桶型）通过双二倍体途径进入六倍体小麦后，可能表现为楔型断节。
The brittle rachis of the Tibetan weedrace (Triticum aestivum var. tibetanum) was found to be governed by a single dominant gene on the short arm of chromosome 3D. The new brittle rachis gene was designated Br-1. This study also discovered that the type of disarticulation is governed by many genes that may differ from brittle rachis genes. In other words, the same brittle rachis gene may exhibit various types of disarticulation in various genetic backgrounds. So, after the brittle rachis gene (barrel type) in Aegilops tauschii entered hexaploid wheat through the amphidiploid path, it might exhibit the wedge type of disarticulation.
