From: Comparative proteomic analysis of somatic embryo maturation in Carica papaya L.
Protein staining with Coomassie brilliant blue R-250 (CBB) in embryogenic cultures ofC. papayaafter 42 days of incubation in the control (without PEG) and PEG6 (with 6% PEG) maturation treatments. (A-B) Control treatment; (C-D) PEG6 treatment; (E) protein granules in embryogenic cells; (F) cotyledonary somatic embryo under PEG6 treatment. Red arrow: non-embryogenic cells; black arrows: embryogenic cells, ma: meristematic aggregates; Asterisks (*): proembryo; pt: protoderm; pr: procambium. PEG: polyethylene glycol. Bars: 200 μm.
