摘要:

随着高通量测序技术的快速发展,多种牧草的基因组和转录组的测序数据相继公布,生物科学已经进入了后基因组时代;基因组学的研究重心也从基因组的结构转向基因功能的挖掘和验证层次,而基因在不同组织的表达量对基因功能挖掘具有重要指导作用。在先前的研究中,育种科学家经常通过柱状图、表格或普通热图等形式对不同组织间的表达量数据进行展示。但这些展示方法形式较为单一,且结果不够美观,读者难以快速有效地获取相关信息。为了更加直观、美观、全面地展示组学数据,本研究以TBtools软件为基础,以紫花苜蓿、蒺藜苜蓿、羊草、黄花草木樨等10种重要牧草为研究对象,结合Adobe Illustrator绘制的SVG文件,构建了一套牧草组学数据可视化工作流程,并以紫花苜蓿中MsSAP基因的表达模式以及不同逆境胁迫下基因的表达模式等为例,从数据获取、热图绘制以及结果展示等方面进行详细介绍。通过与传统的图形展示方式相比较,结果发现,利用本研究提供的牧草SVG图形文件以及可视化流程对多组学数据进行可视化,科研人员能够更快速、高效、美观地展示自己的多组学研究结果,从而为后续深入挖掘功能基因及功能验证提供指导。

Abstract:

The post-genomic era in biological science has commenced with the publication of genome and transcriptome sequencing data for numerous forage grasses enabled by the rapid advancement of high-throughput sequencing technologies. The focus of genomics research has shifted from understanding genome structure to the level of identifying and validating gene functions. What’s more, gene expression in different tissues plays an important guiding role in the mining of gene function. In previous studies, most expression data across different tissues in the field of breeding research have only been presented in formats such as histograms, tables, or basic heatmaps. However, the visualizations conveyed by these methods are relatively simple in form, and the results are not visually compelling, making it difficult for readers to obtain relevant information quickly and effectively. In order to display combinatorial data more intuitively, aesthetically, and comprehensively, this study developed a forage data visualization workflow, which uses TBtools software and ten important forage grasses and legumes, including Medicago sativaMedicago truncatulaLeymus chinensis, and Melilotus officinalis as the species for investigation. By combining with a file drawn by Adobe Illustrator, a set of forage omics data and visualization workflow was constructed. The expression pattern of the MsSAP gene in alfalfa and the changes in expression under different stresses was taken as a case study to illustrate data acquisition, heatmap generation and result visualization when using the workflow. Compared with the traditional graphic display method, it was found that by using the forage SVG graphics files and visualization processes provided by us to visualize multi-omics data, researchers can more rapidly, efficiently and aesthetically visualize their own multi-omics research results, so as to provide a basis for the subsequent in-depth mining of functional genes and functional verification.
