1. The porphyra is rich in nutrition and has high value for food and medical purposes.

2. Simultaneous extraction of protein and polysaccharide from Porphyra yezoensis by pulsed ultrasound was studied.

3. Porphyra is one of the most important marine algae, which has a global distribution and an important economic value.

4. In order to investigate the stimulation of layer Porphyra spp.

5. Conclusion:Porphyra Polysaccharide in proper concentration can reinforce immune function in mice.

6. Porphyra polysaccharide has been widely applied to food, medicine, zoo nutrition industry etc because of its special biological functions.

7. In this study, we constructed SSH library of Porphyra yezoensis successfully and analysised the differences between spermatangium cells and nutrition cells.

8. Porphyran, which was polysaccharide extracted from Porphyra is an important active composition.

9. The study on genetic basis of Porphyra is very important to its breeding exploitation, including the reproduction and life history, which are controlled by gene.

10. Porphyra is the leading cultural species of the seaweed cultivation and the main export sea product in China.

11. For comparative study, phycoerythrin from Porphyra haitanensis was also purified and its properties were compared with that of phycoerythrin from Bangia fusco-purpurea.

11.

12. The meiosis in Porphyra is an important theoretical basis for breeding and genetic studies.

13. Porphyra is a kind of economic marine alga and has been playing an important role in cultivation of seaweeds.

14. By microwave-isted extraction and intermittent microwave radiation heating, the new technology of obtaining Porphyra haitanensis polysaccharides was studied.

15. After an analysis of the published papers and our elementary study, we draw the conclusion that meiosis in Porphyra has not been solved satisfactorily and further research is needed.

16. The stipe of the mushroom and the thallus of red algae (e. g. Porphyra) are pseudoparenchymatous tissues.

17. The study of P. pururea is the only research of sex determination mechanism of Porphyra till now.

18. In order to learn more about the growth and development of unisexual vegetative cells of Porphyra haitanensis, female and male vegetative tissues and cells of P.

19. The blades were guided to variation in order to select and cultivate new strains of Porphyra haitanensis that were high quality and high yield.

20. The time resolved polarized fluorescence of oriented R phycoerythrin single crystal from red alga Porphyra yezoensis was studied in picosecond time scale.

21. Pigment mutants provide excellent germplasm resources and ideal experiment materials for Porphyra genetic breedings, physiological and gene functional researches.

22. The study was carried out in 1984-1987. The somatic cells of thallus were isolated by enzymolysis from Porphyra haitanensis, then cultivated in MES medium.

23. In the paper, the processing technology of semidry seasoned instant laver food was introduced, using Porphyra yezoensis as raw material.

24. Objective Polysaccharide fractions F1, F2 and F3 were prepared from Porphyra haitanensis by hot-water extraction and DEAE-cellulose chromatography.
