UMAP- Gene coexpression landscape
The UMAP projection captures the global coexpression structure of 15,000 highly variable genes across embryo tissues. Distinct yet interconnected regions emerge, reflecting the molecular transitions between cotyledon, embryo coat, and shoot/root domains. The smooth boundaries suggest shared expression programs involved in embryo patterning and nutrient allocation.
These transporters play key roles in the assimilation, mobilization, and redistribution of nitrogenous compounds, mediating amino acid flux between source and sink tissues. AAPs primarily transport neutral and acidic amino acids during growth and nitrogen response, while CATs facilitate the transport of cationic amino acids, contributing to nitrogen balance and intercellular signaling.
