简介：使用植物生产heterologous蛋白质由于潜在地低的费用使它很吸引人。用这个过程，为临床的应用生产药用的蛋白质，植物生物反应器逐渐地增加是可能的。纸建议植物生物反应器以及他们的优点和劣势和每个系统的发展的五个主要系统。集中于植物生物反应器的五个主要系统在我的实验室上的现在的阶段和研究生产疫苗，抗体和医药蛋白质和研究成就。象新基因，新生物部件，新技术和新研究方法那样的工厂生物反应器的关键技术研究在未来为长期的开发与工厂生物反应器提议联系了一个工作基础。

简介：MicroRNAs(miRNAs)是他们在植物和动物的目标基因的重要post-transcriptional管理者。miRNAs通常长是20-24核苷酸。尽管有他们的不平常地小的尺寸，miRNA基因家庭的进化历史似乎类似于编码theirprotein对应物。与在动物染色体的小却丰富的miRNA家庭相对照，植物有少数但是更大的miRNA基因家庭。植物miRNA基因家庭的成员经常是高度类似的，建议经由双人脚踏车基因复制和部分复制事件的最近的扩大。尽管许多miRNA基因越过植物种类被保存，一样的基因家庭在不同种类在尺寸和genomic组织显著地变化，它可以在目标基因规定引起剂量效果和空间、时间的差别。在这评论，我们在理解植物miRNA基因家庭的进化总结当前的进步。
