Figure Legend Snippet: ( A ) Etiolated maize B73 (left) allowed successful protoplast isolation on the automation platform, yielding abundant high-quality protoplast cells (pictured at 40x magnification, middle). Subsequent transfection with the Cas9 vector (p201GFP-Cas9) induced GFP fluorescence in numerous cells (right). ( B ) Protoplast isolation from N. benthamiana leaves (left) using automation yielded abundant and high-quality protoplast cells (pictured at 40x magnification, middle). Protoplasts transfected with the Cas9 vector (p201GFP-Cas9) exhibit GFP fluorescence (right). ( C ) Total intact cell number was counted under three types of PEG (2050, 3350, 4000) treatments in the etiolated maize B73 and N. benthamiana . Biological replicate n = 4. ( D ) Transfection efficiency (Ratio of GFP-expressing and total intact cell numbers) in four days after transfection. Biological replicate n = 4. ( E ) Detection and quantification of chlorophyll fluorescence intensity following HCF136 gene knockout in both maize and N. benthamiana . n = 10. ( F ) Mutation analysis of the HCF136 gene performed using next-generation Sanger sequencing and Inference of CRISPR Editing (ICE) analysis ( ; ) in maize and N. benthamiana . ( G ) Nucleotide sequences identified through ICE analysis following knockout of the HCF136 gene in N. benthamiana callus. ( H ) Overview of the single-cell MALDI workflow for callus-derived protoplasts. ( I ) Protoplast cells in the W5 liquid media were imaged to check the quality before performing MALDI/MS (on the left). Then, using Hoechst staining method to stain the cells, they were imaged (In the middle and on the right). ( J ) Mass spectra with identified lipid species annotated. Error bars represent standard error. Asterisks indicate: *** P < 0.001; ** P < 0.01; * P < 0.05, calculated using two-tailed Welch’s t-test.
