The rapid progress in comparative analysis of cereal genomes reveals that they are composed of similar genomic building blocks. It seems that by simply rearranging these blocks and amplifying some of the repetitive sequences contained within them, it is possible to reconstitute the 56 different chromosomes found in wheat, rice, maize, sorghum, millet and sugarcane. Comparison of the orders of blocks in these reconstituted chromosomes reveals that the cleavage of a single chromosome formed from the blocks could give rise to all the combinations found in the chromosomes of the above species. A framework is now in place for collating all the information which has been generated from studying the individual cereals.
谷物基因组比较分析的快速进展表明，它们由相似的基因组构建块组成。似乎只需重新排列这些构建块并扩增其中包含的一些重复序列，就有可能重建在小麦、水稻、玉米、高粱、小米和甘蔗中发现的56条不同染色体。对这些重建染色体中构建块顺序的比较表明，由这些构建块形成的单个染色体的断裂可能产生上述物种染色体中发现的所有组合。现在已经有了一个框架，用于整理从对各个谷物的研究中产生的所有信息。
