Dissertation Research: Molecular and Ultrastructural Adaptations Characterizing the Transient Symbiosis of Gymnodinium acidotum and Chroomonas

小行星9311481 本研究是对藻类光合内共生体建立的研究。 本研究将以淡水甲藻Gymatoniumacidotum和隐藻Chromonas之间的共生关系为模式系统，研究甲藻的摄食方式、隐藻对甲藻膜的影响以及隐藻对甲藻叶绿体的形态学变化。 没有研究提供实验证据证明，在涉及内共生体的交换中，适应性促进叶绿体的获得。 这项研究是在细胞水平上研究这种收购的首批调查之一。 这一结果可能为不同藻类如何获得叶绿体提供了一个解释。 ***

9311481 Russell This research is an investigation of the establishment of photosynthetic endosymbionts in algae. The symbiotic relationship between the freshwater dinoflagellate, Gymnodinium acidotum, and the cryptophyte Chroomonas will be used as a model system to study: 1) the mode of ingestion used by the dinoflagellate; 2) the alterations of the dinoflagellate membrane following the acquisition of the cryptophyte; and 3) the morphological changes occurring in the cryptophyte chloroplast following ingestion. %%% There are no studies that offer experimental evidence for adaptations that promote the acquisition of chloroplasts in exchanges involving endosymbionts. This research is one of the first investigations to examine this acquisition at the cellular level. The results may provide an explanation for how different divisions of algae obtained their chloroplasts. ***
