Phloem is the highly specialised sugar conducting tissue found in all living vascular plants, and it is today always occurs with xylem, the specialised water conducting tissue. Both of these tissues enabled plants to become larger and more complex, but how did these tissues evolve? 1/

Congratulation @transitionalform.bsky.social @instmolplantsci.bsky.social for publishing the next chapter of your thesis @currentbiology.bsky.social ! Great work showing that the two fundamental vascular tissues - xylem and phloem evolved asynchronously. Read Laura's thread for more details 👇👇

Not sure which scRNA-seq platform to use for 🪴 plant samples? How well do doublet detection algorithms really work in 🌱? How can I optimise sample prep ? Find out in our benchmark study! Led by @carogro.bsky.social and @thomaseekhout.bsky.social. Open access at EMBO Journal: doi.org/10.1038/s443...

doi.orgBenchmarking plant single cell RNA-sequencing sample processing strategies - The EMBO JournalThe isolation of single plant cells from complex tissues is prone to selective enrichment and sampling biases, which complicates accurate profiling of the large diversity in cell types. Optimizing methodologies for cell enrichment and single-cell transcriptomics is therefore critical for single-cell studies addressing plant cell heterogeneity. Here, we systematically compared protoplast enrichment technologies (including conventional and image-based flow cytometry, as well as magnetic cell sorting) and single-cell RNA sequencing (scRNA-seq) platforms (10X Genomics Chromium, BD Rhapsody) using Arabidopsis roots. Image-based flow cytometry offered increased precision due to customizable gating strategies, while magnetic sorting provided faster processing and enhanced representation of cell size heterogeneity. Both scRNA-seq platforms captured root cell heterogeneity and yielded reproducible gene expression profiles, but showed platform-associated differences in cell type composition. Notably, single-nucleotide polymorphism analysis of a mixed ecotype sample revealed that, among cells identified as doublets by computational algorithms, two-thirds were likely to have been misclassified. These insights identify key biases in plant cell purification and scRNA-seq workflows and provide practical guidance for improving data quality across plant species.
