Rapid progress in epigenetic studies has resulted in genome wide information of genetic functions, other than DNA sequence information. However, insufficient understanding and unclear research direction in epigenetics has failed to attract many researchers. Here, we review the sexual reproduction pr...

크로마틴 기능이 FWA 유전자의 전사를 저해한다고 생각되는 이유는? | 2012). 한편, Ikeda et al. (2011)은 FACT 히스톤 chaperone 구성 단백질을 코드하는 SSRP1 유전자의 경우에는 met1 돌연변이체와 ssrp1 돌연변이체와 이중헤테로 접합체에서는 중앙세포의 met1 변이에 의한 ssrp1 돌연변이 억제 효과는 미미하였으며, met1 돌연변이체와dme 돌연변이체와 이중헤테로 접합체의 결과와는 다른 양상을 보였다. 이 때문에 DNA 메틸화 이외에도 크로마틴 기능이 FWA 유전자의 전사를 저해하고 있다고 생각되며,SSRP1 유전자의 기능과 잘 일치한다고 하였다(Formosa 2012). | |
식물의 생식과정은 어떠한가? | 식물은 적당한 광과 온도 조건이 되면 꽃을 피우게 되는데 이는 다음 세대에 종자를 전달하는 가장 기본적인 행위이다. 식물의 생식과정은 수술과 암술의 상호작용에 의해 종의 정체성 유지 및 집단의 다양성 유지 면에서 놀라울 정도로 역동성을 지니고 있다. 식물은 후성유전학 정보를 포함한 유전정보를 다음세대로 어떻게 제대로 전달하는지, 어떤 허용범위 내에서 변화되어 전달하는지, 만약 전달되었다며 어떤 특성과 다양성이 부여되는지, 또는 세대를 거듭함에 따라 진화에 어떤 영향을 주는지에 대한 정보는 아직 자세히 밝혀져 있지 않다. | |
