Dinoflagellates are a vital diverse family of unicellular algae widespread in various aquatic environments. Typically large genomes and permanently condensed chromosomes without histones make these organisms unique among eukaryotes in terms of chromatin structure and gene expression. Genomic and transcriptomic sequencing projects have provided new insight into the genetic foundation of dinoflagellate behaviors. Genes in tandem arrays, trans-splicing of mRNAs and lower levels of transcriptional regulation compared to other eukaryotes all contribute to the differences seen. Here we present a general overview of transcription in dinoflagellates based on previously described work.
甲藻是单细胞藻类中一个重要且多样的家族，广泛分布于各种水生环境中。典型的大基因组和无组蛋白的永久浓缩染色体，使这些生物在染色质结构和基因表达方面在真核生物中独具特色。基因组和转录组测序项目为甲藻行为的遗传基础提供了新的见解。串联排列的基因、mRNA的反式剪接以及与其他真核生物相比更低水平的转录调控，都导致了所观察到的差异。在此，我们基于先前描述的工作，对甲藻的转录进行一个总体概述。
