Abstract

Epistatic interactions and negative heterosis have been shown to be associated with interchromosomal interactions in wheat. Physical gene-gene interactions between co-regulated genes clustered in "transcription factories" have been documented, and a genome-wide atlas of functionally paired, interacting regulatory elements and genes of wheat recently produced. Integration of these new studies on gene and regulatory element interactions, co-regulation of gene expression in "transcription factories," and epigenetics generates new perspectives for wheat breeding and trait enhancement.

摘要

上位性互作和负向杂种优势已被证明与小麦的染色体间相互作用有关。已记录了聚集在“转录工厂”中的共同调控基因之间的物理基因-基因相互作用，并且最近绘制了一份小麦功能配对、相互作用的调控元件和基因的全基因组图谱。将这些关于基因和调控元件相互作用、“转录工厂”中基因表达的共同调控以及表观遗传学的新研究整合起来，为小麦育种和性状改良带来了新的视角。
