Abstract
Chitinase was induced in rice cell suspension culture with treatment of chitooligosaccharides mixture. Among eleven isozymes found in 10% polysacrylamide gel electropherogram, four isozymes were identified as induced enzymes. Acidic chitinase fraction separated in DEAE-cellulose column chromatography, includes three induced chitinase, while basic fraction contains only one induced isozyme. Treatment of chitooligosaccharides mixture enhanced the contents in both protein and chitinase activity in cell suspension culture media, but increase in chitinase activity was much higher than in protein.
Chitooligosaccharides 혼합물을 처리한 벼 세포 현탁배양액과 처리하지 않은 배양액의 단백질 및 효소활성을 비교하여 이 elicitor에 의해 유도되는 chitinase를 확인하였다. Chitooligosaccharide 혼합물 처리로 chitinase 활성은 비처리구에 비하여 3.5배 증가하였으며 증가율이 단백질 증가보다 10배 이상 높아 본 효소가 선택적으로 유도되는 것으로 나타났다. Polyacrylamide gel 전기영동상 나타나는 총 11종의 chitinase중 4종이 유도효소로 판명되었으며 DEAE-cellulose chromatography 결과 3개는
