Abstract：
Maize survival under the anaerobic stress due to submergence conditions is dependent on complex metabolic, physiological and morphological adaptation strategies. Here, we focus on gene expression regulation at the transcriptional and post-transcriptional level in submerged maize root cells. Early in progressive oxygen deprivation, root cells sense the low oxygen signal to trigger expressions of TF genes, anaerobic response genes and miRNA genes. The induced TFs, in turn, promote a broad spectrum of responses from morphogenetic to metabolic; these responses occur at later stages of the stress treatment. The selective translation of anaerobically induced transcripts and selective degradation of some APs are also suggested to be an important regulatory mechanism. In addition, miRNAs are possibly transcriptionally regulated in submerged root cells and involved in post-transcriptional control of target genes. Thus, regulation of gene expression in response to low oxygen involves in significant transcriptional and post-transcriptional control.
摘要：
玉米在无氧胁迫下的存活由于淹没条件而依赖于复杂的代谢,生理和形态适应策略。这里,我们专注于淹没玉米根细胞中转录和转录后水平的基因表达调控。在进行性缺氧的早期，根细胞感知低氧信号以触发TF基因的表达，厌氧反应基因和miRNA基因。诱导的TFs，反过来,促进从形态发生到代谢的广泛反应;这些反应发生在压力治疗的后期。厌氧诱导转录物的选择性翻译和一些AP的选择性降解也被认为是重要的调控机制。此外,miRNA可能在浸没的根细胞中被转录调节，并参与靶基因的转录后控制。因此，响应低氧的基因表达调节涉及重要的转录和转录后控制。
