Abstract
An important step during plant development is the transition from juvenile to adult growth. It is only after this transition that plants are reproductively competent. Given the great danger that transposon activity represents to the germ line, this may also be an important period during development with respect to transposon regulation and silencing. We demonstrate that a change in expression of a key component of the RNA silencing pathway is associated with both vegetative phase change and shifts in epigenetic regulation of a maize transposon.
摘要
在植物发育过程中，一个重要的步骤是从幼年生长到成年生长的转变。只有在这个转变之后，植物才具有生殖能力。鉴于转座子活动对生殖系的巨大威胁，这也可能是发育过程中与转座子调控和沉默相关的一个重要时期。我们证明，RNA 沉默途径的一个关键组成部分的表达变化与营养阶段变化和玉米转座子的表观遗传调控变化都有关联。
