巨大螺旋藻光合放氧和超微结构的研究

STUDIES ON PHOTOSYNTHETIC OXYGEN-EVOLUTION AND ULTRASTRUCTURE IN SPIRULINA MAXIMA

  • 摘要: 选用常温下培养的巨大螺旋藻(Spirulina maxima)为材料,对其光合放氧与超微结构进行了观察和研究。结果表明:1)巨大螺旋藻具有较强的放氧能力;2)巨大螺旋藻细胞内存在有含量极丰富的类囊体、气泡、藻胆体及羧化体等特定结构与其光合放氧特性相适应;3)类囊体膜片层在细胞的部分区域已趋于重叠,且封闭成一独立系统存在,具类似真核生物叶绿体的结构;4)从进化角度来看,巨大螺旋藻类囊体膜存在的方式可以作为叶绿体系统演化的证据之一,即真核藻类和高等植物叶绿体可以认为是由蓝藻光合器官演化而形成,巨大螺旋藻是过渡类型之一。

     

    Abstract: We selected the blue-green Spirulina maxima to reserch the photosynthetic oxygen-evolution and ultrastructure.Spirulina maxima was cultured in our laboratory.The results show:1)Spirulina maxima has higher capability of photosynthetic O2-evolution;2)The thylokoids membrane,gas vacuoles,carboxysomes and phycobilisome,were prestened in cell.These photosynthetic apparatus and cell structure organelle were adapted with the role of photosynthetic oxygen-evolution.3)The thylokoids membrane regularly arranged and stacked in part regions of cytoplasm,and becomed a whole system of light energy conversion as chloroplast in higher plants.4)In evolution opinion,the existense type of thylokoid and special structure in Spirulina maxima showed part evidense:supporting the close similarity between photosynthetic appratus of blue-green algae and the chloroplast of eukarytes.The chloroplast of green algae and higher plant evolve from the photosynthetic appratus of prokaryotic blue-green algae.Spirulina maxima is one of representatives of evolutionary link between blue-green algae and higher plant.
