翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Pseudocyphellaria ： ウィキペディア英語版 Pseudocyphellaria ''Pseudocyphellaria'' is a genus of large, leafy lichens that are sometimes referred to as "specklebelly" lichens.〔Brodo, I. M., S. D. Sharnoff, and S. Sharnoff. 2001. ''Lichens of North America''. Yale University Press: New Haven. ISBN 0-300-08249-5〕 The genus has a widespread distribution, especially in south temperate regions, and contains about 170 species. They resemble ''Lobaria'', except that all species of ''Pseudocyphellaria'' have conspicuous pseudocyphellae on their lower surface, a characteristic that is unique to this genus.〔 Some species contain pulvinic acid-related pigments; in these species the soredia and pseudocyphellae can be bright yellow.〔 ==The ''Pseudocyphellaria'' symbiosis== Many species of ''Pseudocyphellaria'' are cyanolichens and contain the cyanobacterium ''Nostoc'' as a photobiont, which allows nitrogen fixation. In some species of ''Pseudocyphellaria'' the cyanobacterium is the sole photobiont, while other species also contain the green alga ''Dictyochloropsis'' and restrict the cyanobacterium to warty cephalodia on the lower surface of the lichen.〔 Some species of ''Pseudocyphellaria'' appear to be able to use either a cyanobacterium or a green algae as their photobiont. DNA tests have shown that the fungal symbionts in ''P. murrayi'' (which is in a symbiosis with a cyanobacterium) and ''P. rufovirescens'' (which is in a symbiosis with a green alga) are actually the same species. This means that ''P. murrayi''-''P. rufovirescens'' is actually one species of fungus that is capable of forming two very different lichens, one with a cyanobacterium and one with a green alga.〔 Two other possible pairs of ''Pseudocellaria'' species that may be capable of choosing their photobiont are ''P. knightii''-''P. lividofusca'', and ''P. kookeri''-''P. durietzii''.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pseudocyphellaria」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
