references / wiktionary / Japanese Wiktionary[edit]

I have added the first reference - I hope I have done it correctly. Osborne 14:54, 2 February 2007 (UTC)

More to be added: Description etc. If time!!!Osborne 15:49, 19 April 2007 (UTC)

Please check my editorial changes. There was a sentence that, IMHO, largely paraphrased the remaining life cycle sentence. I am going to see if I can add some wiktionary links for the terms not in Wikipedia. I am working with a company in this field and will probably learn something useful in the course of my research, probably mostly about uses, including non-food uses.

There must be some good material on porphyra in the Japanese Wiktionary. I will try to see how to bring that it to the English. DCDuring 15:36, 30 August 2007 (UTC)

Bot-generated content[edit]

A computerised algorithm has generated a version of this page using data obtained from AlgaeBase. You may be able to incorporate elements into the current article. Alternatively, it may be appropriate to create a new page at Porphyra (alga). Anybot (contact operator) 02:20, 21 February 2009 (UTC)

Please begin with a sentence simply saying in plain language what Porphyra is.[edit]

Is this correct? If so, it would do:

Porphyra is a cold water seaweed that grows in cold shallow sea water.

Life Cycle is incorrect[edit]

The haploid gametophyte generation does not produce spores - it produces gametes via mitosis. The gametes then fuse on the female to form the diploid carposporophyte, which produces diploid carpospores by mitosis. The carpospores then grow into the diploid conchocelis, which bores into shells and produces haploid conchospores by meiosis. The conchospores then grow into the male and female gamteophytes.

Also, Porphyra includes many dioecious species (separate male and female plants), thus both female and male gametes are not always "formed on the one thallus." The male species is more yellow in colour, while the female is more pink in colour (as it needs more of the red photosynthetic pigment to produce enough food to sustain itself and the carposporophyte).

If someone could edit this with the relevant citations that would be great, otherwise I should get to it soon. — Preceding unsigned comment added by 105.225.182.187 (talk) 22:41, 10 June 2015 (UTC)

Porphyra/Pyropia Major reworking needed? Inappropriate main image?[edit]

Following the reported reassessment of the genus Porphyra, and the moving of a significant number of taxa into the genus Pyropia is not the use of the image of Porphyra yezoensis inappropriate here? I note that the same image is also used on the new page for Pyropia, there labelled as Pyropia yezoensis.

Of greatest significance is the statement in Sutherland et al's 2011 revision that: "The genus Porphyra is now restricted to five described species and a number of undescribed species. Other foliose taxa previously placed in Porphyra are now recognized to belong to the genera Boreophyllum gen. nov., Clymene gen. nov., Fuscifolium gen. nov., Lysithea gen. nov., Miuraea gen. nov., Pyropia, and Wildemania. Four of the seven filamentous genera recognized in our analyses already have generic names (Bangia, Dione, Minerva, and Pseudobangia), and are all currently monotypic."

I'm afraid I don't know enough about these genera to make the necessary changes myself. Regards from the UK, Nick Moyes (talk) 09:03, 15 September 2017 (UTC)

  • Sorry I didn't reference my additions on Pyropia. But here is what i used: [1]. i know it's going to be a bit of work, especially with gim and nori involved, but we gotta do it. Wikispecies is already updated. Maybe it's a good time to switch to Automatic Taxoboxes? Nessie (talk) 14:37, 15 September 2017 (UTC)
