The rbcL gene of Ulva pertusa,Enteromorpha prolifera and Monostroma grevillei was amplified,sequenced and analyzed.By comparing the rbcL sequences with seven other Ulvales species retrieved from GenBank,the sequence divergences and the phyletic evolution were analyzed and the phylogenetic tree was constructed.From the phylogenetic tree,it can be found that U.pertusa,E.prolifera and U.californica group in one branch,while E.compressa,U.rigida and U.fenestrata cluster in another clade.Obviously,unlike the Enteomorpha species,the Ulva species do not gather in one branch.Therefore Ulva and Enteomorpha might be affiliates of one genus.E.compressa and E.intestinalis gathered together,which coincided with the morphological characters.However,the thallus of U.pertusa is thick and with many holes,which is different from E.prolifera in morphology.They cluster together in the phylogenetic tree with a genetic distance of 0.005.The results indicate that Ulva and Enteromorpha are not distinguished strictly. 相似文献

Effect of temperature and irradiance on the growth and reproduction of Enteromorpha prolifera J. Ag. （Chlorophycophyta, Chlorophyceae） 总被引：1，自引：0，他引：1
Effect of temperature and irradiance on growth and reproduction of Enteromorpha prolifera that bloomed offshore along the Qingdao coast in summer 2008, was studied. It was showed that E. prolifera propagated mainly asexually with specific growth rate (SGR) of 10.47 at 25°C/40 μmol m-2s-1. Under this condition, gametes with two flagellate formed and released in 5 days. At the beginning of the development, the unicell gamete divided into two cells with heteropolarity, and then the apical cell developed into thalli primordial cells, whereas the basal cell developed into rhizoid primordial cells. In 8-day culture, the monoplast gamete developed into juvenile germling of 240 μm in length. Unreleased gametes can develop directly within the alga body. E. prolifera could either reproduce through lateral branching or fragmenting except apomixis revealed by Microscopic observation. On aged tissue of E. prolifera, although the degraded pigments partially remained in faded algal filaments, numerous vegetative ceils could still divide actively in the algal tissues. 相似文献

The marine macroalgae Enteromorpha prolifera was one of the main algal genera that occurred in the widespread green tides in Qingdao, China, during the summers of 2007, 2008 and 2010. It is thus a plentiful source of biomass and could be used as a biofuel. In this study, the pyrolytic characteristics and kinetics of E. prolifera were investigated using thermogravimetric analysis (TGA) method. Cornstalk and sawdust were used as comparisons. Pyrolytic characteristics were studied using TG-DTG (thermogravimetry-derivative thermogravimetry) curves. Three stages in the pyrolytic process were determined: dehydration, dramatic weight loss and slow weight loss. E. prolifera was pyrolyzed at a lower initial temperature than the two terrestrial biomass forms. The apparent activation energy values for the three types of biomass were calculated and the mechanism functions were determined using 16 different mechanism functions, frequently used in thermal kinetics analysis. Activation energy values varied with mechanism function and the range of activation energy values for E. prolifera, cornstalk, and sawdust were 25-50 kJ/mol, 60-90 kJ/mol and 120-155 kJ/mol, respectively. This indicates that E. prolifera has low thermal stability for pyrolysis and good combustion characteristics. 相似文献

Ulvacean green seaweeds are common worldwide; they formed massive green tides in the Yellow Sea in recent years, which caused
marine ecological problems as well as a social issue. We investigated two major genera of the Ulvaceae, Ulva and Enteromorpha, and collected the plastid rbcL and nuclear ITS sequences of specimens of the genera in two sides of the Yellow Sea and analyzed them. Phylogenetic trees
of rbcL data show the occurrence of five species of Enteromorpha (E. compressa, E. flexuosa, E. intestinalis, E. linza and E. prolifera) and three species of Ulva (U. pertusa, U. rigida and U. ohnoi). However, we found U. ohnoi, which is known as a subtropical to tropical species, at two sites on Jeju Island, Korea. Four ribotypes in partial sequences
of 5.8S rDNA and ITS2 from E. compressa were also found. Ribotype network analysis revealed that the common ribotype, occurring in China, Korea and Europe, is connected
with ribotypes from Europe and China/Japan. Although samples of the same species were collected from both sides of the Yellow
Sea, intraspecific genetic polymorphism of each species was low among samples collected worldwide. 相似文献

It has been a scientific consensus that Ulva prolifera green tide that break out annually between May and August in the recent decade off eastern coast of Yellow Sea. To investigate the ecological mechanism of the decline of U. prolifera green tide, we compared the physiological characteristics of U. prolifera samples collected in three stages of the green tide in Subei Shoal north Jiangsu, the initiation point, on May 10(early, the initiation), July 10(middle, the outbreak), and in Taipingjiao, Qingdao on August 10(late, the decline). Compared to the early samples, the middle, and late samples showed a lower chlorophyll content and photosynthetic e fficiency at a higher lipid peroxidation level. The middle and later samples had fewer chloroplasts in the cells of U. prolifera than those in the early samples. In addition, the cells of U. prolifera sampled in the late stage showed ruptured and deformed cell walls. Differences in physiological function were reflected in the growth rate. Both the middle and late U. prolifera samples presented negative growth rates. Correlation analysis results show that the rising temperature was mainly responsible for the local decline of U. prolifera green tide. The high light-intensity that could induce the photoinhibition was also an important factor for the decline. Therefore, U. prolifera population that remained in the Subei Shoal and those that northward drifted to Qingdao experienced the same decline processes: rising temperature and continuous high light conditions in the late phase of green tide reduced the photosynthetic capacity and destroyed the antioxidant system of the thallus, which lead to decrease of biomass. The only difference is that the temperature in the Subei Shoal rose earlier than that in Qingdao; thus, U. prolifera remaining in the Subei Shoal went disappeared first. 相似文献

Pyrenoids found in green algae Order Ulvales have taxonomical significance.Their morphology,microstructure,and the location and number in the cells have been widely used as identification criteria. As these traits can be affected by environmental conditions,it is necessary to look for other different characteristics.Here pyrenoids in several algae species collected along the Qingdao coast were studied for such purpose. The morphology and distribution of pyrenoids in the cells,as well as their change in diff... 相似文献

In this study,a polysaccharide from Enteromorpha prolifera(EP)was extracted and its effect on maize seedlings under NaCl stress was investigated.Firstly,the components and structure of the EP were determined.We found that EP is a sulfated polysaccharide of high-molecular weight(Mw,1 840 KDa)heteropoly saccharides and the main mono saccharide is rhamno se.The poly saccharide was applied to explore its effect on the growth of maize seedlings and its defense response under a salt stress.The results show that EP could promote the growth of maize seedlings under the salt stress.In addition,EP was shown able to significantly regulate membrane permeability and adjustment of osmotic substances such as soluble protein,soluble sugar,and proline,antioxidant enzymes containing superoxide dismutase,catalase,peroxidase,and ascorbate peroxidase.Therefore,EP is an effective salt-resistant substance for the growth of maize seedlings under NaCl stress. 相似文献
