Abstract

To define diversity of domestic radish, we analysis genetic relationship of anti-fungal protein genes from several domestic radish (Raphanus sativus L.) seeds. We have isolated from domestic radish (Baekwoon) anti-fungal protein named RAP[12]. In this report, we isolate RNAs and raw protein from radish seeds then, RT-PCR analysis was done with another known anti-fungal sequences of radish from Gene Bank/EMBL and anti-fun- gal, anti-yeast activity were done against Bot교tis cenerea, Saccharomyces cerevisiaeι Candida albicans with it's raw proteins. The anti-fungal activity was shown used all seeds but anti-yeast activity was shown only two seeds (Myungsan, Baekwoon). RT-PCR products (about 0.2 Kb) were not shown only two seeds. To identify the sequencing relationship of the domestic radish, we have cloned and sequenced RAP genes of the radish and analysis the sequence relationship with clustalw program. Thus we report the result that there are some different relationship between domestic radish and known other radish's anti- fungal protein[15].

국내 시판 무 (Baekwoon) 의 씨앗으로부터 항 진균 단백질들을 (RAP-l,2)분리 하였으며[12] 이들 항 진균 단백질을 MALDI-TOF실험결과, 2S storage albumin, Rs-AFP등 지하부 식물의 defensin protein과[15] 일치함을 확인하였고 이에 시판되는 7종의 각각의 무 씨앗으로부터 조 단백질과 Total RNA를 분리 하여 항 효모 (Saccharomyces cerevisiae, Candida albicans.) 및 항 곰팡이 (Botrytis cenma)에 대한 항 진균성을 실험한 결과 항 곰팡이 활성은 모든 품종에서 보였으나 항 효모 활성은2 종 (Myungsan, Baekwoon) 의 무에서만 보였 다 . 또한 기존에 알려진 항 진균 단백질 (Rs-AFP)의 유전자를 Gene Bank/EMBL 에서 획득하여 씨앗으로부터 분리한 Total RNA 에 RT-PCR 한결과, 7종 중 2종은 0.2kb 의 산물이 보이지 않았다. 이들 Ks-AFP 유전자산물을 염기서열을 분석하였으며 이 염기서열에서 얻어진 아미노산 서열을 Clustal W를 이용한 pairwise alignment 분석에 의해 국내 시판 무 의 품종간 각clone의 계통수를 분석한 결과를 보고한다.
