Polyploidy is centrally important in the evolution and domestication of plants because it leads to major genomic changes, such as altered patterns of gene expression, which are thought to underlie the emergence of new traits. Despite the common occurrence of these globally altered patterns of gene expression in polyploids, the mechanisms involved are not well understood.

染色质可及性降低是二倍体 Aegilops tauschii 和六倍体小麦同源染色体臂基因表达差异的基础。

多倍体在植物的进化和驯化中至关重要，因为它会导致主要的基因组变化，例如基因表达模式的改变，这被认为是新性状出现的基础。尽管在多倍体中这些全球改变的基因表达模式很常见，但所涉及的机制尚不清楚。
