Integrated Cannabis glandular-trichome head-versus-stalk transcriptomics and proteomics, supporting distinct head specialization for secondary-metabolite production and stalk roles associated with growth, transport, sugar and hormone signaling, and precursor supply.
Visual lesson 08
Head, stipe & stalk specialization
Compare the metabolically specialized gland head with the stipe and multicellular stalk using recent multi-omics evidence: head tissues emphasize specialized-metabolite production and accumulation, while stalk tissues show distinct growth, transport, sugar, hormone-signaling, and precursor-supply programs.
