Figure 1From: Next generation sequencing unravels the biosynthetic ability of Spearmint (Mentha spicata) peltate glandular trichomes through comparative transcriptomicsTrichomes on spearmint leaf. (A) Scanning electron microscope image of spearmint leaf showing three types of trichomes, a, Non glandular hairy trichome; b, Peltate glandular trichome (PGT); c, Capitate glandular trichome. (B) Process of secretion by PGT. a, presecretory stage; b, formation of storage cavity; c, secretion into the storage cavity; d, release of oil upon injury. The PGTs were stained with toulidine blue.Back to article page
