spartina anglica polyploidy

Invasive Spartina species induce major geomorpholgical changes in tidal habitats by enhancing rates of sediment accumulation. It arose as a result of chromosome doubling in S. x townsendii, a hybrid between the native British S. maritima and the North American S. alterniflora, introduced by shipping (Figure 3). This fingerprinting technique involves the restriction of genomic DNA by two restriction enzymes (here, EcoRI –MseI and PstI –MseI) followed by selective amplification of a subset of the restriction fragments, and has been used successfully for the screening of structural changes in polyploids (Liu et al., 2001; Ozkan et al., 2001). It is also encountered in California where it was introduced during the 19th century. The aquatic pteridophyte Isoetes and the three unrelated aquatic angiosperm genera Crassula, Littorella and Alisma all exhibit CAM (Keeley, 1996) and clearly they do not suffer water deficits. Abundant Spartina alterniflora pollen improves seed set in Spartina foliosa, producing fertile hybrids that also cross with the native species. The native geographic distribution of the genus centers on the east coast of North and South America, with fewer species on the west coast of North America, Europe, and north Africa. Rapid evolutionary responses to agricultural herbicide application also occur frequently, with crop weeds developing herbicide resistance. After a period of uncertainty concerning chromosome numbers of Spartina, Marchant (1968) was the first to establish that the basic chomosome number in Spartina is × = 10, as in most other Chloridoideae. late 1950s/early 1960s would reduce nutrients from sewage entering Holes Bay, but it would not completely eradicate them as nitrogen removal technology was not introduced until 2008 (Jones, D. (Wessex Water) pers. The molecular data also confirm the morphological resemblance between S. patens and S. bakeri that appear closely related (Baumel et al., 2002a). Relative to C3 species of similar form, C4 photosynthesis allows young plants, in a limited period of time, to accumulate more mass or to achieve the same mass but with higher root to shoot ratios. Spartina × neyrautii and S. × townsendii lack 9.0% and 7.3% of the discriminant parental fragments, respectively. Exploring the genome of the salt-marsh Spartina maritima (Poaceae, Chloridoideae) through BAC end sequence analysis. 34.3). Rapid structural and epigenetic reorganization near transposable elements in hybrid and allopolyploid genomes in Spartina. Both AFLP and MSAP reveal that hybridization, rather than polyploidization, is the main process that has shaped the structure of the allopolyploid genome of S. anglica.

Bruno, 2000; Van Hulzen et al., 2007). [fully fertile] [fully fertile] [fully fertile] [sterile hybrid] Carbon isotope discrimination analyses show that many species can switch between pathways, and in Frerea indica, the perennial succulent stems have CAM whereas the seasonal leaves, only produced in the wet season, have C3 photosynthesis (Lange and Zuber, 1977). The role of hybridization, polyploidization and glaciation in the origin and evolution of the apomictic Ranunculus cassubicus complex. Effects of prescribed burning on gulf cordgrass, Spartina spartinae (Trin.) This species originated on the south coast of England at the end of the nineteenth century. In this paper, we examine how these approaches have helped our understanding of speciation in the grass genus Spartina Schreb., where hybridization and polyploidy represent past and ongoing important evolutionary forces. There are also ultrastructural differences in the chloroplasts. The combined use of maternally inherited cytoplasmic markers with those biparentally inherited from the nuclear genome has allowed a more precise parentage identification in many plant groups, with the possibility to detect multiple and recurrent origins of species (Soltis et al., 1992) and to get a more accurate picture of species formation via introgression (Rieseberg & Brunsfeld, 1992). Hybridization and the colonization of novel habitats by annual sunflowers. This system allows investigations of the early evolutionary changes that accompany stabilization of a new allopolyploid species in natural … Plant speciation – rise of the poor cousins,, Total discriminant fragments between parents, Polymorphic fragments between parents (28). The UVR index also declines during Phase 2 suggesting an increase in algae preventing sunlight penetrating the water column. Compact genomes and complex evolution in the genus Brachypodium. This species is a fertile, perennial plant that has been actively colo-nizing the salt marshes and estuaries of Britain and France since 1890 and 1906, respectively. Ancient Gene Duplicates in Gossypium (Cotton) Exhibit Near-Complete Expression Divergence. Spartina anglica displays wider ecological amplitude than its parents across the successional sequence of salt marsh zones (Thompson, 1991). A multiple species approach to biomass production from native herbaceous perennial feedstocks. The extant Spartina species either are tetraploid (2n = 40), hexaploid (2n = 60–62), or dodecaploid (2n = 122, 124), with possible aneuploidy (Marchant, 1968). glabra Hampshire There is little novel biochemistry involved in the C4 pathway, and the classification of a plant as C3, C4 or CAM therefore depends on the degree of morphological specialization (Kranz anatomy, succulence), metabolic behaviour (e.g. F1 hybrids produced between two established related species are often sterile because chromosomes lack sufficient homology to pair well at meiosis.
