Lipid Biosynthesis in Epidermal, Guard and Mesophyll Cell Protoplasts from Leaves of Vicia faba L

  • Naoki Sato

Abstract

Epidermis is known to be the site of synthesis of long-chain fatty acids which are supposed to be precursors to components of epicuticular wax1. Epidermis of leaf tissue is composed of epidermal cells and guard cells, which are different in cellular architecture, including plastid morphology: plastid development is generally repressed in epidermal cells while guard cell chloroplasts are active in photosynthesis and starch synthesis. In the light of the current view that the plastid is the sole site of synthesis of fatty acids, I suspected that epidermal and guard cells are quite different in ability to synthesize long-chain fatty acids.
