Abstract

Transposable elements (TEs) are repetitive DNA sequences with the ability to replicate across genomes and generate mutations with major transcriptional effects. Epigenetic silencing mechanisms that target TEs to limit their activity, including DNA methylation, add to the range of gene expression variants generated by TEs. Here, using the iconic gene flowering locus C (FLC) as a case study I discuss the multiple ways by which TEs can affect the expression of genes and contribute to the adaptation of plants to changing environments.

转座因子对植物转录新颖性的贡献:FLC事件。
转座因子(te)是一种重复的DNA序列,具有跨基因组复制的能力,并产生具有主要转录效应的突变。包括DNA甲基化在内的针对te的表观遗传沉默机制限制了它们的活性,增加了te产生的基因表达变异的范围。本文以开花基因座C (FLC)为例,讨论了TEs影响基因表达和促进植物适应环境变化的多种途径。
