中文摘要 | 本研究利用放射性碳 14 標定之水楊酸 , 探討外加水楊酸在菸草懸浮培養細胞之代謝過程。 200μM 水楊酸處理之菸草懸浮培養細胞 5 分鐘內約吸收 39.46% 外加的水楊酸 , 被吸收的水楊酸大部分會被細胞再排出至培養液中 ,5 小時後約 2.62% 及 91.55% 的水楊酸分別存在於細胞內及培養基濾液中,細胞排出水楊酸之過程受 EGTA 之抑制,而外加鈣離子可反轉 EGTA 之抑制作用。由以上結果建議外加水楊酸由200μM 處理之菸草懸浮培養細胞排出時需要外來的 Ca[]離子 , 而且可能與需要鈣離子之水楊酸排出途徑有關。 |
英文摘要 | The radioactive 14C-Salicylic acid (SA) was used to monitor the metabolism of exogenous SA in tobacco cell suspension culture. Tobacco cells took up ca. 39.46% of the applied SA 5 min after the addition of a final 200 VIM SA mixture containing [14C]SA to the cell suspension culture. Most of the SA absorbed by the cells was gradually lost to the culture medium, and 2.62% and 91.55% of the radioactivity were found in the cells and the culture filtrate, respectively, 5 h after treatment. Excretion of SA to the culture medium required external Ca2+ and was inhibited by EGTA pretreatment. The inhibition was reversible through the supplement of Ca 21 to the cell suspension culture. Based on the data, we conclude that SA excretion from the 200 μM-treated cells requires external Ca 2' and likely involves a putative Ca 2'-dependent pathway in tobacco suspension culture. |
