Since the discovery of the first dual targeted protein in plants in 1995 the number of dual targeted proteins in plants has grown to over 250 proteins. Much work and investigations have focused on identifying how or what makes a protein dual targeted. Recently, more research has focused on the evolution and conservation of dual targeting of proteins in plants. This new work has demonstrated that dual targeting arose early within the evolution of plants and because it is rarely lost, once gained, it must be under some positive selection pressure. The possible reasons as why proteins are dual targeted and why it was conserved during the evolution of plants are discussed.
自 1995 年首次在植物中发现第一个双靶向蛋白以来，植物中的双靶向蛋白数量已增长到超过 250 种。大量的工作和研究都集中在确定是什么或是什么使一种蛋白质成为双靶向。最近，更多的研究集中在植物中双靶向蛋白的进化和保守性上。这项新的研究表明，双靶向在植物进化的早期就出现了，而且由于它很少丢失，一旦获得，它一定受到某种正选择压力的影响。本文讨论了为什么蛋白质是双靶向的，以及为什么在植物进化过程中它得以保守。
