TITLE：Cell-Specific Regulatory Dynamics underlying C₄ Photosynthesis

ABSTRACT：

C₄ plants epitomize a category of terrestrial flora renowned for their superior efficiency in utilizing light, water, and nitrogen relative to their C₃ counterparts, a trait further amplified by the compartmentation between mesophyll and bundle sheath cells. This cellular differentiation significantly bolsters the carbon concentration mechanism, thereby enhancing photosynthetic productivity. Intriguingly, the genes encoding C₄ photosynthetic enzymes, though inherent in their C₃ ancestors, assume pivotal importance in C₄ plants due to their distinct expression patterns. This talk will delve into our group's latest maize (single-cell) multi-omics study, scrutinizing the role of transcription factors in the distinct cellular environments of C₄ plants. It aims to discuss the impact of these factors on photosynthetic efficiency, exploring the underlying genetic and epigenetic regulatory mechanisms that govern the variances in gene expression across different cell types.
