Moss species Physcomitrella patens has been used as a model system in plant science for several years, because it has a short life cycle and is easy to be handled. With the completion of its genome sequencing, more and more proteomic analyses were conducted to study the mechanisms of P. patens abiotic stress resistance. It can be concluded from these studies that abiotic stresses could lead to the repression of photosynthesis and enhancement of respiration in P. patens, although different stresses could also result in specific responses. Comparative analysis showed that the responses to drought and salinity were very similar to that of abscisic acid, while the response to cold was quite different from these three. Based on previous studies, it is proposed that sub-proteomic studies on organelles or protein modifications, as well as functional characterization of those candidate proteins identified from proteomic studies will help us to further understand the mechanisms of abiotic stress resistance in P. patens.
藓类植物拟南芥已被多年来被用作植物科学的模式系统，因为它具有短的生命周期并且易于处理。随着其基因组测序的完成，越来越多的蛋白质组学分析被用于研究拟南芥非生物胁迫抗性的机制。这些研究表明，非生物胁迫可能导致拟南芥光合作用的抑制和呼吸作用的增强，尽管不同的胁迫也可能导致特定的反应。比较分析表明，干旱和盐胁迫的反应与脱落酸非常相似，而寒冷胁迫的反应则与这三种完全不同。基于先前的研究，提出对细胞器或蛋白质修饰进行亚蛋白质组学研究，以及对蛋白质组学研究中鉴定的候选蛋白进行功能表征，将有助于我们进一步了解拟南芥非生物胁迫抗性的机制。
