Anthocyanin is a vital indicator for both fruit nutritional and commercial value. Anthocyanin accumulation is a surprisingly complicated process mediated by multiple networks associated with genetic, developmental, hormonal, and environmental factors. Transcriptional regulation along with epigenetic regulation constitutes the dominant molecular framework for anthocyanin biosynthesis. Here, we focus on current knowledge on regulatory mechanisms of anthocyanin accumulation, with emphasis on the latest progress in transcriptional and epigenetic regulation and the crosstalk between various signaling pathways. We present an emerging picture of how various internal and external stimuli control anthocyanin biosynthesis. Additionally, we discuss the synergistic or antagonistic effect of developmental, hormonal and environmental cues on anthocyanin accumulation in fruit.
花色苷是水果营养和商业价值的重要指标。花色苷的积累是一个由多个与遗传、发育、激素和环境因素相关的网络介导的复杂过程。转录调控和表观遗传调控构成了花色苷生物合成的主要分子框架。在这里,我们重点介绍花色苷积累的调控机制的最新知识,强调转录和表观遗传调控以及各种信号通路之间相互作用的最新进展。我们呈现了一个关于各种内外刺激如何控制花色苷生物合成的新图景。此外,我们还讨论了发育、激素和环境信号对果实中花色苷积累的协同或拮抗作用。
