STAR LABThe resin storage cavity develops through changes in specialised cell-wall regions.
A changing structure
A 2021 study by Livingston and colleagues examined wall components during cannabis glandular trichome development. Chemical analyses and antibody-based imaging revealed changes in specific wall regions as the extracellular storage cavity formed and filled. [1]
What the authors observed
Cavity formation involved separation of the subcuticular wall from the underlying surface wall. The researchers identified changing distributions of wall polysaccharide markers and a matrix surrounding metabolite droplets. Their evidence supports a developmental relationship between wall remodelling and metabolite storage.
Keep the conclusion in scope
This work concerns plant anatomy and development. It does not establish the purity of a finished material, compare commercial micron specifications, or measure a particular PSL specimen. Our reading recommendation is to separate three questions: what structure is present, what compounds were measured, and what conclusion the experiment directly supports. For the related cellular perspective, read Inside a trichome.
