Tolerance may be generated by increase of sugar concentration. A moss, Bryum argenteum is widely distributed on stones and concrete walls all over the world, and is tolerant to desiccation for a long time. Several kinds of sugar are synthesized by this species. We have investigated whether some of these sugars increased upon desiccation. The moss was collected from the field, and was kept in three conditions; i.e., 80 % relative humidity, low temperature (4C), and ABA (abscisic acid) for 1, 3 and 6 days, respectively, and the sugar content was analyzed using HPLC. For control experiment, B. argenteum was kept in moist condition at 25C as control experiment. Sucrose content (mg/g dry weight) increased in low temperature and ABA treatment as well as control experiment. This suggests that sugars are synthesized without exposure to excess stresses., 共催: 日本学術会議, joint hosting: The Science Council of Japan, 資料番号: AA0064730061}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {乾燥、低温およびアブシジン酸処理によるギンゴケの糖量変化}, volume = {26}, year = {2010} }
