While recent advances in plant single-cell RNA sequencing (scRNA-seq) have made numerous strides in identifying novel regulatory events, transcriptional profiling of certain cell types, such as phloem poles, has not yet been thoroughly investigated. A recent article by Otero et al. utilized cell-type specific marker lines and a second-generation single-cell approach to uncover transcriptomic landscapes specifying protophloem-adjacent cells, as well as identify a set of important transcription factors (TFs) signifying early phloem development.
虽然植物单细胞 RNA 测序 (scRNA-seq) 的最新进展在鉴定新的调控事件方面取得了许多进展，但某些细胞类型（如韧皮部极点）的转录谱尚未得到彻底研究。最近，Otero 等人利用细胞类型特异性标记线和第二代单细胞方法，揭示了指定原韧皮部相邻细胞的转录组图谱，并确定了一组重要的转录因子 (TFs)，它们标志着早期韧皮部发育。
