Ever observe maize produce 90 leaves before flowering? See Mark's and Zuhaa's preprint for their new proposed flowering time model. Multimodal single cell analysis reveals a link between flowering and leaf initiation biorxiv.org/content/10.64898…

‼️A new story from our lab!🙌 We show that SNI1, a component of the SMC5/6 complex, acts as a temperature-dependent brake on class II crossovers, helping shape where genetic exchange occurs in Arabidopsis. Huge effort by Alex made it happen🙏

1/2 My very first post on X—and what better occasion than the publication of our paper in @NaturePlants! 🌱 We identify SNI1 as the first plant gene linking temperature to meiotic recombination, generating genetic diversity that may help plants adapt. nature.com/articles/s41477-0…

🚨How many reads in a single-cell barcode come from that cell? 🚨 We loaded maize and Arabidopsis nuclei into separate wells of the same scifi-ATAC plate. Arabidopsis barcode averaged 73% maize reads, yet standard QC looked normal! New preprint 🧵 biorxiv.org/content/10.64898… 1/10

📣 Please share! We’re recruiting to build predictive models of gene regulation in plants. We’d love to hear from anyone with strong foundations in regulatory genomics or ML and fluency with coding agents. Any career stage; no plant background needed. noborilab.org 1/4

Excited to launch our ERC project ImmuneCellState 🚀 We’ll study how individual plant cells respond to pathogens and explore new dimensions of plant immunity research by integrating single-cell/spatial omics, deep learning and genome editing. @TheSainsburyLab @ERC_Research

A comprehensive understanding of heterosis has long been out of reach. Led by postdoc Luguang Jiang, we applied scifi-ATAC-seq to 🌽 inbreds and their recip hybrids, and identified a widespread loss of cell-type-specific ACRs in hybrid genomes 🧬 1/10 biorxiv.org/content/10.64898…

Taken together, we believe cell-specific regulatory mechanisms play a much larger role in heterosis than previously appreciated. Importantly, none of these discoveries would have been possible without single-cell genomics. 9/10
