1氰化物的来源及其在植物中的功能研究进展显示文摘氰化物广泛存在于自然界,人们熟知其毒理特性,但有关氰化物的来源及其功能却知之甚少。尤其值得注意的是,植物自身能产生氰化物并利用氰化物,且被证实在植物生长发育及逆境胁迫应答过程中扮演着重要角色。现对植物体内氰化物的来源及其在植物种子萌发及抗逆等方面的功能研究进行综述,并展望了氰化物的研究方向及应用前景。余璐璐 刘杨 徐飞 2019生命科学2019,31,2:10
2Baptism by fire: the pivotal role of ancient conflagrations in evolution of the Earth's flora显示文摘Fire became a defining feature of the Earth's processes as soon as land plants evolved 420 million years ago and has played a major role in shaping the composition and physiognomy of many ecosystems ever since.However, there remains a general lack of appreciation of the place of fire in the origin, evolution, ecology and conservation of the Earth's biodiversity. We review the literature on the presence of fire throughout the Earth's history following the evolution of land plants and examine the evidence for the origin and evolution of adaptive functional traits, biomes and major plant groups in relation to fire. We show that:(1) fire activities have fluctuated throughout geological time due to variations in climate, and more importantly in atmospheric oxygen, as these affected fuel levels and flammability;(2) fire promoted the early evolution and spread of major terrestrial plant groups;(3) fire has shaped the floristics, structure and function of major global biomes; and(4) fire has initiated and maintained the evolution of a wide array of fire-adapted functional traits since the evolution of land plants. We conclude that fire has been a fundamental agent of natural selection on terrestrial plants throughout the history of life on the Earth's land surface. We suggest that a paradigm shift is required to reassess ecological and evolutionary theories that exclude a role for fire,and also there is a need to review fire-suppression policies on ecosystem management and biodiversity conservation in global fire-prone regions.Tianhua He Byron B.Lamont 2018National Science Review2018,5,2:1
