| Abstract: | The progress in diversities of life history and reproductive mode in the genus Porphyra is reviewed in this paper. The basic life history of Porphyra is heteromorphic and biphasic with a haploid foliose gametophyte and a diploid filamentous sporophyte. And there are other types of life history, i.e. sexual and asexual reproduction as well as vegetative proliferation in the foliose thallus and filamentous thallus are summarized respectively. The position of meiosis and sex development are also discussed. The paper is quite helpful to systematize our knowledge to Porphyra life history and reproductive modes so that it will promote the research on mechanism of diverse life history that is focused in recent years and its application in Porphyra breeding. |
