It exhibits remarkable tolerance to extremely acute or long-term dehydration stress. However  it cannot withstand prolonged hydration or water saturation. It appears that too little water limits its growth while too much water becomes a burden. This seemingly contradictory situation is particularly pronounced in N. flagelliforme  reflecting its distinctiveness among Nosotcspecies with respect to the ways they adapt to dry environments. In this review  we call attention to potentially important drought-adaptation mechanisms in this species  including mechanisms related to its morphology  structure  ecophysiology and genetic background  summarizing the available studies relevant to this topic. This species may become a good model for investigating the diverse genetic mechanisms of Nostoc adaptation to dry environments.   Tunnel erosion and sediment production in the hilly loess region, North China 期刊论文 JOURNAL OF HYDROLOGY, 2002, 卷号: 257, 期号: 1-4, 页码: 78-90 作者:  Zhu, TX;  Luk, SH;  Cai, QG 收藏  |  浏览/下载：14/0  |  提交时间：2019/09/26 Piping  Semi-arid Environments  Loess  Erosion
