A single-cell transcriptomic atlas reveals the cell differentiation trajectory and the response to virus invasion in swelling clove of garlic.

ABSTRACT: The garlic bulb comprises several cloves, the swelling growth of which is significantly hindered by the accumulation of viruses. Herein, we describe a single-cell transcriptomic atlas of swelling cloves with virus accumulation, which comprised 19 681 high-quality cells representing 11 distinct cell clusters. Cells of two clusters, clusters 7 (C7) and 11 (C11), were inferred to be from the meristem. Cell trajectory analysis suggested the differentiation of clove cells to start from the meristem cells, along two pseudo-time paths. Investigation into the cell-specific activity of invasive viruses demonstrated that garlic virus genes showed relatively low-expression activity in cells of the clove meristem. There were 2060 garlic genes co-expressed with virus genes, many of which showed an asso
