Single-cell RNA sequencing opens a new era for cotton genomic research and gene functional analysis

Single-cell RNA sequencing (scRNA-seq) is one of the most advanced sequencing technologies for studying transcriptome landscape at the single-cell revolution. It provides numerous advantages over traditional RNA-seq. Since it was first used to profile single-cell transcriptome in plants in 2019, it has been extensively employed to perform different research in plants. Recently, scRNA-seq was also quickly adopted by the cotton research community to solve lots of scientific questions which have been never solved. In this comment, we highlighted the significant progress in employing scRNA-seq to cotton genetic and genomic study and its future potential applications.
