characterized by genes like CUC (red) separate the primordia from the. Z-stacks were acquired in a 512 × 512 pixel format, with a resolution of 12-bit depth, section spacing of 1 m and line averaging 2. to model the mechanics of 3D tissues during growth at cellular resolution. In addition to this rich dataset, we developed single-cell analysis software, Socrates, which can be used to understand cis-regulatory variation in any species. VENUS was imaged using argon laser (excitation wavelength 514 nm) while tdTomato was imaged using a white light laser (excitation wavelength 561 nm). Using amplified femtosecond laser pulses, we ablated the internal tissues in young leaf primordia of tomato (Solanum lycopersicum) without damaging the overlying L1 and L2. Through comparison of maize and Arabidopsis thaliana developmental trajectories, we identified TFs and CREs with conserved and divergent chromatin dynamics, showcasing extensive evolution of gene regulatory networks. We have developed a precise microsurgical tool to ablate the midvein at high spatial and temporal resolution in order to test its function in leaf formation and phyllotaxis. Moreover, we found cell-type-specific CREs are hotspots for phenotype-associated genetic variants and were targeted by selection during modern maize breeding, highlighting the biological implications of this CRE atlas. Cell-type-specific CREs were enriched for enhancer activity and within unmethylated long terminal repeat retrotransposons. GB: How did you first become interested in creating Primordia VIC: For a long time, I focused solely on concept art for other people's games. Resolution extended to visualization of small cells in meristem tissue, ovules within the silique. Using single-cell genomics in six maize organs, we determined the cis- and trans-regulatory factors defining diverse cell identities and coordinating chromatin organization by profiling transcription factor (TF) combinatorics, identifying TFs with non-cell-autonomous activity, and uncovering TFs underlying higher-order chromatin interactions. Here to provide answers about Primordia’s development are Wormwood Studios’ Vic Pflug and Mark Yohalem as well as Wadjet Eyes’ Dave Gilbert and composer Nathaniel Chambers. developing leaves, roots, and lateral root primordia. (17) He made the resolution readily, and with the help of Gods grace and by constant effort, he kept it to a wonderful. Cis-regulatory elements (CREs) encode the genomic blueprints of spatiotemporal gene expression programs enabling highly specialized cell functions.
