另外是一项工作(http://www.sciencemag.org/content/336/6087/1448.short)是拟南芥中另外两个基因 AtMORC1 and AtMORC6。AtMORC1 and AtMORC6 are members of the conserved Microrchidia (MORC) adenosine triphosphatase (ATPase) family, which are predicted to catalyze alterations in chromosome superstructure. 他们工作从实验上证明了AtMORC1 and AtMORC6 是影响染色质结构,使基因表达沉默,并且在线虫中也保守(看来在进化值得做做,嘿嘿)。
