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

[3111481] Russell本研究是对藻类光合内共生体建立的调查。本文将淡水甲藻、裸子藻和隐生藻之间的共生关系作为模型系统来研究：1)甲藻的摄食方式；2)获得隐殖后鞭毛膜的改变；3)摄入后隐生植物叶绿体的形态变化。没有研究提供实验证据，证明在涉及内共生体的交换中，适应性促进了叶绿体的获得。这项研究是在细胞水平上研究这种获取的第一次调查之一。这一结果可能解释了藻类的不同分裂是如何获得叶绿体的。＊＊＊

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. ***
