Abstract:
Chromosome studies provide the foundation for comprehending inheritance, variation, systematics, and evolution. Penaeid shrimps are a group of crustaceans with great economic importance. Basic cytogenetic information obtained from these shrimps can be used to study their genome structure, chromosome relationships, chromosome variation, polyploidy manipulation, and breeding. The study of shrimp chromosomes experienced significant growth in the 1990s and has been closely linked to the progress of genome research since the application of next-generation sequencing technology. To date, the genome sequences of five penaeid shrimp species have been published. The availability of these genomes has ushered the study of shrimp chromosomes into the post-genomic era. Currently, research on shrimp cytogenetics not only involves chromosome counting and karyotyping, but also extends to investigating submicroscopic changes; exploring genome structure and regulation during various cell divisions; and contributing to the understanding of mechanisms related to growth, sexual control, stress resistance, and genome evolution. In this article, we provide an overview of the progress made in chromosome research on penaeid shrimp. We emphasize the mutual promotion between studies on chromosome structure and genome research and highlight the impact of chromosome-level assembly on studies of genome structure and function. Additionally, we summarize the emerging trends in post-genomic-era shrimp chromosome research.
摘要:
染色体研究为理解遗传提供了基础,变异,系统学,和进化。对虾是一类具有重要经济意义的甲壳类动物。从这些虾获得的基本细胞遗传学信息可用于研究它们的基因组结构,染色体关系,染色体变异,多倍体操作,和繁殖。对虾染色体的研究在1990年代经历了显着的增长,并且自从下一代测序技术的应用以来一直与基因组研究的进展紧密相连。迄今为止,五种对虾的基因组序列已经发表。这些基因组的可用性将对虾染色体的研究带入了后基因组时代。目前,对虾细胞遗传学的研究不仅涉及染色体计数和核型分析,但也延伸到调查亚微观变化;探索各种细胞分裂过程中的基因组结构和调控;并有助于理解与生长有关的机制,性控制,抗应力,和基因组进化。在这篇文章中,我们概述了对虾染色体研究的进展。我们强调染色体结构研究与基因组研究之间的相互促进,并强调染色体级组装对基因组结构和功能研究的影响。此外,我们总结了后基因组时代对虾染色体研究的新兴趋势。
