The three-dimensional (3D) structure of bacterial chromosomes is crucial for understanding chromosome function. With the growing availability of high-throughput chromosome conformation capture (3C/Hi-C) data, the 3D structure reconstruction algorithms have become powerful tools to study bacterial chromosome structure and function. It is highly desired to have a recommendation on the chromosome structure reconstruction tools to facilitate the prokaryotic 3D genomics. In this work, we review existing chromosome 3D structure reconstruction algorithms and classify them based on their underlying computational models into two categories: constraint-based modeling and thermodynamics-based modeling. We briefly compare these algorithms utilizing 3C/Hi-C datasets and fluorescence microscopy data obtained from Escherichia coli and Caulobacter crescentus, as well as simulated datasets. We discuss current challenges in the 3D reconstruction algorithms for bacterial chromosomes, primarily focusing on software usability. Finally, we briefly prospect future research directions for bacterial chromosome structure reconstruction algorithms.
细菌染色体的三维(3D)结构对于理解染色体功能至关重要。随着高通量染色体构象捕获(3C/Hi-C)数据的不断普及,3D 结构重建算法已成为研究细菌染色体结构和功能的强大工具。人们非常希望能够推荐染色体结构重建工具,以促进原核生物的 3D 基因组学研究。在这项工作中,我们回顾了现有的染色体 3D 结构重建算法,并根据其底层计算模型将它们分为两类:基于约束的建模和基于热力学的建模。我们简要比较了这些算法,利用了从大肠杆菌和新月柄杆菌获得的 3C/Hi-C 数据集和荧光显微镜数据,以及模拟数据集。我们讨论了细菌染色体 3D 重建算法中的当前挑战,主要集中在软件可用性上。最后,我们简要展望了细菌染色体结构重建算法的未来研究方向。
