Survey on members of sucrose-world in Asian tropical reef, namely in Thailand

植物通过光合作用在叶片中合成淀粉。叶淀粉转化为蔗糖，并运输到储存器官（例如，块茎和子实体），然后再形成淀粉（贮藏淀粉）。从身体的许多部位，植物分泌蔗糖，植物通过蔗糖与环境生物进行串扰（例如，微生物和昆虫）。近年来，人们发现植物体内存在大量的蔗糖分泌系统（称之为蔗糖世界）。本研究的目的是调查蔗糖世界成员（环境生物及其酶）在泰国，那里有高日照。结果表明，在根分泌蔗糖时，存在“蔗糖->多糖->次生糖或三元糖”的系统。对花蜂蔗糖转化为低聚糖的酶也进行了研究。

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.
