We report the identification of a family of sequences located by in situ hybridisation to the centromeres of all the Triticeae chromosomes studied, including the supernumerary and midget chromosomes, the centromeres of all maize chromosomes and the heterochromatic regions of rice chromosomes. This family of sequences (CCS1), together with the cereal genome alignments, will allow the evolution of the cereal centromeres and their sites to be studied. The family of sequences also shows homology to the CENP-B box. The centromeres of the cereal species and the proteins that interact with them can now be characterised.
我们报告了通过原位杂交鉴定出的一个序列家族，该家族位于所有研究的小麦族染色体的着丝粒上，包括额外染色体和微型染色体，所有玉米染色体的着丝粒以及水稻染色体的异染色质区域。这个序列家族（CCS1），连同谷物基因组比对，将有助于研究谷物着丝粒及其位点的进化。该序列家族还显示出与CENP - B框的同源性。现在可以对谷物物种的着丝粒及其相互作用的蛋白质进行表征。
