“…The expression of phloem system marker gene ZmCALS2 (Zhong et al, 2023) was also lower at the early stage but increased and peaked after middle stage, while another marker gene homolog of AtNEN3 displayed a prominent peak erupted from very low base level (contribution of both mostly from cluster 11 cells) (Figure 11D; Supplemental Figures 8A and 8B). Xylem related genes including homolog of AtLOG6 and ZmWAT1 (Xu et al, 2021) were not expressed at the early stage, but expression levels increased steeply at later stages of pseudo-time (the contribution of expression was clearly from cluster 12) (Figure 11D; Supplemental Figures 8C and 8D).…”

SummaryTypical C4plants such as maize possess highly optimized Kranz-type leaf anatomy, whereby concentric wreaths of mesophyll and bundle sheath cells surround closely spaced veins. The veins and the cells that surround them are derived from the middle ground meristem (mGM) through processes that are as yet undefined. Here we distinguished the active zone of vascular development within early leaf primordia, and used comparative transcriptomics of sub-sectioned maize and rice primordia to identify cohorts of genes likely involved in early Kranz development. Leveraging single-nucleus RNA sequencing (snRNA-seq) we then explored the cell heterogeneity and developmental trajectories within single maize leaf primordia. Assisted byin situhybridization, cell clusters of mGM and procambium were identified, with candidate marker genes showing different yet inter-related expression patterns. Localization of the vascular markerZmSHR1was preceded by that ofZmEREB161andZmEREB114in terms of procambium initiation. Potential subclusters of bundle sheath cells and different layer of mesophyll cells were depicted from developing cells toward the tip of sub-sectioned maize primordia. Collectively our results identify potential mGM derived or procambium localized Kranz regulators and provide resources for investigating leaf vein development in maize and rice, at sub-primordium and single-cell resolution.
