Abstract
Heterocystous cyanobacteria grow as multicellular organisms with a distinct one-dimensional developmental pattern of single nitrogen-fixing heterocysts separated by approximately ten vegetative cells. Several genes have been identified that are required for heterocyst development and pattern formation. A key regulator, HetR, has been recently shown to be aserine-type protease.
摘要
异形胞蓝细菌以多细胞生物体的形式生长，具有独特的一维发育模式，单个固氮异形胞被大约十个营养细胞隔开。已经鉴定出几个异形胞发育和模式形成所需的基因。最近发现一种关键调节因子HetR是一种丝氨酸型蛋白酶。
