Title: | Towards a comprehensive survey of C₃ and C₄ photosynthetic pathways in Cyperaceae | Contributor(s): | Bruhl, Jeremy James (author) ; Wilson, Karen (author) | Publication Date: | 2007 | Handle Link: | https://hdl.handle.net/1959.11/3931 | Abstract: | Members of the family Cyperaceae were surveyed by original observation and from the literature to assess the distribution of C₃ and C₄ photosynthetic pathways in the family. All 107 genera were included in the current sample, with 91 genera assessed as consistently C₃ and 11 genera as C₄. The genera 'Abildgaardia', 'Cyperus', 'Eleocharis',' Fimbristylis', and 'Rhynchospora' are variable for this trait. Of the total number (1474) of specific (1406) and infraspecific (68) taxa sampled, 938 taxa (63%) are C₃, 527 taxa (36%) are C₄, and nine species of Eleocharis are debatably intermediate or variable in pathway. Some data suggesting further infrageneric variation in photosynthetic pathways are discussed. The "one cell distant criterion" accurately predicts C₄ pathway in sedges, except in Eleocharis. Distribution and variability of photosynthetic pathways in Eleocharis are discussed. Photosynthetic pathway was found to be a useful taxonomic marker in Cyperaceae, despite variability in this trait at various taxonomic levels and the apparently multiple origin of C₄ photosynthesis within the family. A checklist of 3395 records of C₃ and C₄ sedges is presented. | Publication Type: | Journal Article | Source of Publication: | Aliso, v.23, p. 99-148 | Publisher: | Rancho Santa Ana Botanic Garden | Place of Publication: | United States of America | ISSN: | 0065-6275 | Fields of Research (FoR) 2008: | 060310 Plant Systematics and Taxonomy | Socio-Economic Objective (SEO) 2008: | 960899 Flora, Fauna and Biodiversity of Environments not elsewhere classified | Peer Reviewed: | Yes | HERDC Category Description: | C1 Refereed Article in a Scholarly Journal | Publisher/associated links: | http://www.rsabg.org/v15/research/scientific-publications |
