By using green fluorescent protein targeted to the plastid organelle in tomato (Lycopersicon esculentum Mill.), morphology of plastids and their associated stromules epidermal cells trichomes from stems petioles chromoplasts pericarp fruit has been revealed. A novel characteristic is presence extensive bead‐like structures along that are often observed as free vesicles, distinct apparently unconnected body. Interconnections between red pigmented chromoplast bodies common suggesting could form a complex network this cell type. The potential implications for carotenoid biosynthesis vesicles originating beaded secretory mechanism glandular discussed.
