Messenger RNAs of a potato (Solanum tuberosum L.) Kunitz-type proteinase inhibitor(s) (PKPI) were present in potato disks excised from tubers stored for 14 months (old tubers) or 2 months (young tubers) after harvest, and disappeared during the aseptic culture. The PKPI mRNA accumulation was found to be induced in potato disks from the old tubers by the addition of jasmonic acid (JA) [3-oxo-2-(2'-cis-pentenyl)-cyclopentane-1-acetic acid].
从收获后储存14个月的块茎（老块茎）或2个月的块茎（幼块茎）上切下的马铃薯（Solanum tuberosum L.）圆盘组织中存在库尼茨型蛋白酶抑制剂（PKPI）的信使核糖核酸，且在无菌培养过程中消失。研究发现，通过添加茉莉酸（JA）[3-氧代-2-（2'-顺式戊烯基）-环戊烷-1-乙酸]，可诱导老块茎的马铃薯圆盘组织中PKPI信使核糖核酸的积累。
