프로토파낙사디올 강화 GM벼의 주요 농업 특성 비교 평가

초록

Genetically modified (GM) crops have been developed to enhance various agronomictraits and increase the production of functional compounds. In the present study,the major agronomic characteristics of protopanaxadiol (PPD)-enriched GM rice, whichwas developed by introducing dammarenediol-II synthase (PgDDS) and protopanaxadiolsynthase (CYP716A47) genes from Panax ginseng into Oryza sativa cv. Dongjin, wereevaluated. The stability of the introduced genes was confirmed using PCR and immunostriptests, which showed consistent expression across multiple generations (T5-T7). Agronomic traits, including days to heading, culm length, panicle length, tiller number, andgrain weight per plant, were compared between GM rice and its non-GM counterpart,Dongjin rice. No significant differences were observed for these traits, indicating that geneticmodification did not affect the overall plant growth. However, seed morphology analysesrevealed that PPD-enriched GM rice had significantly longer brown rice grains. Incontrast, other seed traits remained within the natural range of commercial rice varieties. Furthermore, PPD was consistently detected in GM rice, whereas it was absent in non-GMDongjin rice. These findings suggest that PPD-enriched GM rice maintains a stable agronomicperformance while successfully accumulating PPD, supporting its potential as afunctional crop. However, further research is required to evaluate its environmental impact,food safety, and efficacy as a functional food source.
