| Research Abstract |
Plants synthesize the starch in the leaves by photosynthesis. Leaf-starch is converted to sucrose, and transported to storage organ (e.g., tubers and fruit-bodies), followed by re-formation of starch (storage-starch). From many sites of bodies, plants secret sucrose, by which plants perform the cross-talk with environmental organisms (e.g., microorganisms and insects). Recently, it was found that huge amount of sucrose was secreted (this system is call as sucrose-world). The purpose of this research is survey of sucrose-world-members (environmental organisms and their enzymes) in Thailand, where high sunshine is available. As a result, the system of "sucrose -> polysaccharide -> secondary or ternary sugar" was investigated at sucrose secreted from roots. About flower bee, the enzyme converting sucrose to oligosaccharide was also investigated.
