| Abstract: |
| Single cell RNA-seq（scRNA-seq） technology is new to study overall gene expression at the single cell level by high-throughput sequencing of mRNA.This paper summarized the development and innovation of single cell transcriptome sequencing technology.The steps of single cell capture or sorting,reverse transcription/PCR amplification,database construction and sequencing data basic analysis of scRNA-seq technology were introduced in detail,and its application in the study of scRNA-seq technology in plant single cell map,abiotic stress response mechanism,cell differentiation and development,and transcription factor regulatory network were introduced.The application potential of single cell map,differentiation,stress resistance and gene in sweet potato was also analyzed.Finally,the application of this technology was prospected. |
