Abstract

We analyzed lignin content and wxpression of OMT gene during growth season in two hybrid poplar species. OMT gene expression was observed mainy in the developing secondary xylem where major quantity of lignin occurs. Lignin content in the xylem tissue increased as plant resumed growth in the spring and reached the highest in the late August. Change in lignin content was concurrent with that of OMT gene expression, indicating OMT is a key enzyme in lignin biosynthesis.

리그닌함량이 감소한 펄프소재의 육성을 위해 OMT유전자와 리그닌생합성 간의 관계를 2종의 포플라 수종을 이용하여 실험하였다. OMT유전자의 발현은 리그닌생합성이 가장 많이 일어나는 developing secondary xylem에서 높앗다. 이 사부조직에서의 리그닌함량의 증가는 봄에 성장을 개시할 때부터 증가하기 시작하여 8월 말 경에 가장 높았다. 이러한 리그닌의 증가는 OMT유전자의 발현 증가와 일치하였으며, 이는 OMT유전자가 리그닌생합성에서 매우 중요한 역할을 함을 나타내는 것이다.
