Outline of Final Research Achievements

Tuber shape and its homogeneity are important factors determining the agricultural quality and productivity of Chinese yams. The aim of this study is to clarify the mechanism of graviperception, gravitropism and morphology formation in Chinese yam tubers. The results strongly supported the possibility that the sedimentable amyloplasts in the tuber tips function as statoliths and are involved in gravity sensing and tuber formation in Chinese yam. In addition, the results suggested that actin filaments and the distribution of auxin in the tuber tips are involved in gravitropism and tuber formation in this study.
