The identification and diversity analysis of red alga in partial Shandong waters
山东部分海域红藻的鉴定与多样性分析

There is a wide variety of red alga, which have great economic values and development prospects. In this study, we analyzed 36 algal samples collected at the intertidal areas in Qingdao, Weihai and Yantai, Shandong province, using morphological methods and molecular techniques. The results of morphological observation revealed that the red algal samples displayed the difference in color, size, shape of thallus and other morphological characterization. At the same time, using the method of molecular systematics, RbcL genes were isolated from the samples and used to reconstruction the evolutionary tree to analyze the genetic relationship and diversity among the samples. The results revealed the collected samples have a closer relationship with 16 genera reported in the Gen-Bank. The samples collected from Qingdao, Weihai and Yantai presented the difference in the diversity. The resultsalso showed a good diversity between species within genera.
