“…The former was higher and the latter was lower in comparison with other results of S. alterniflora in its native places (Perkins et al, 2002). This result could be interpreted through the history of the H T -total genetic diversity; H S -intra-population genetic diversity; Gst-the coefficient of genetic differentiation Chung et al, 2004).…”

“…By comparison, Travis et al (2002) found that the average PPB was 41% for three restored and one natural S. alterniflora populations on the Gulf coast of southern Louisiana, and 30.70% for a (2007) 583:195-204 199 single population. Perkins et al (2002) also detected polymorphism levels as high as 63% in three restored and four natural S. alterniflora populations and the average PPB was 33% for a single population. In this study, average heterozygosity (H E = 0.0657) of tall form S. alterniflora was also lower than the average values (0.131) in its native places (Travis et al, 2002;Travis & Hester, 2005).…”

Spartina alterniflora Loisel., a highly invasive species on the Chinese coast, is a focus of increasing management concerns due to its high expansion rate in tideland and the significant damages on native ecosystems, since its introduction into China in 1979. There are both tall and dwarf forms of the species in China. The tall form with strongly invasive ability has widely expanded. Genetic variation was examined within and among three tall form S. alterniflora populations in Jiangsu Province using amplified fragment length polymorphisms (AFLP) markers. Three populations were sampled along the coastal line, and each population was divided into three subpopulations relating with the three microenvironments: Foreland, mid-marsh and upland. Genetic diversity was low at both the population level (PPB = 22%, H E = 0. 0657 and H pop = 0.099) and at the species level (PPB = 24.65%, H T = 0.0814 and H sp = 0.1225). A low level of genetic differentiation among populations was detected based on analyses of coefficients of genetic differentiation (9.51%), Shannon's diversity index (9.48%) and AMOVA (10.69%). The mean value of Gst among nine subpopulations was 22.02%. Habitat selections may occur and affect the genetic structure of S. alterniflora in the process of its spread because there are 7.2, 3.4 and 5.9% specific bands out of 158 polymorphic bands in foreland, mid-marsh, and upland, respectively. This genetic differentiation may result from seedling survival and colonization success based on the selection of specialized microhabitats. The results indicated that high capability of genetic differentiation within populations and strong adaptability of tall form S. alterniflora may be the reasons for the widespread expansion of the tall form S. alterniflora.

“…The East-American S. alterniflora has been introduced to the Pacific coast of the US where it is now an invasive weed, most notably in the San Francisco Bay area (Daehler and Strong, 1997) and in Willapa Bay (Aberle 1993 in Daehler andStrong, 1997). In both sites, as well as on the eastern coast, the species shows a high level of nuclear and chloroplast diversity (Stiller and Denton 1995;Anttila et al, 2000;Perkins et al, 2002).…”

Uniformity of the nuclear and chloroplast genomes of Spartina maritima (Poaceae), a salt-marsh species in decline along the Western European Coast

Spartina maritima is a salt-marsh species from European and African Atlantic coasts. In the northern range of the species (including north-west France), a rapid decline of the populations has been observed during the 20th century. In this paper, the molecular diversity of 10 populations of S. maritima from France has been investigated using nuclear and chloroplast DNA markers: inter-simple sequence polymorphism (ISSR), randomly amplified polymorphic DNA (RAPD), inter-retrotransposon amplified polymorphism (IRAP), and PCR-RFLP of a 5 kb long portion of chloroplast DNA. The results reveal an extremely low level of genetic variation in this species: only one nuclear marker (out of 98) was polymorphic, with the presence of two genotypes randomly distributed among the populations. The lack of genetic diversity is interpreted in light of the almost exclusive vegetative propagation of the species in its northern range, the colonization history of the populations, and the origin of S. maritima (2n ¼ 60) in the hexaploid lineage of the genus and in the context of the management of S. maritima populations.

“…Few studies on genetic diversity utilized Random Amplified Polymorphic DNA (RAPD) (Stiller and Denton 1995;O'Brien and Freshwater 1999;Ryan et al 2007) and Amplified Fragment Length Polymorphism (AFLP) markers (Travis et al 2002;Perkins et al 2002;Subudhi et al 2008;Utomo et al 2008). The study of Stiller and Denton (1995) suggested that all S. alterniflora clones in Willapa Bay are descended from a single genet.…”

Salinity is one of the most serious abiotic stresses affecting crop productivity worldwide. Improving tolerance to salinity in field crops is globally important because a majority of the world population relies on salt-sensitive crops such as rice, corn, and wheat for their daily calories. Although there is no salt stress sensor yet identified, different signaling components and tolerance mechanisms have been substantiated to a great extent in a glycophyte like Arabidopsis, and more recently in a few halophytes. With the rapid advances in genetics, genomics, and biochemical and transformation tools, it is now possible to explore the genetic and molecular basis of the unusually high level of salt tolerance in halophilic plants. We will focus on a halophyte grass, Spartina alterniflora, commonly known as smooth cordgrass, which possesses all known mechanisms of salt tolerance and subsequent exploitation of its genome information for crop improvement. A number of candidate genes encoding transcription factors, ion transport, osmoprotectants, antioxidants, detoxifying enzymes, etc. have been identified. Although recent efforts to develop salt tolerant cultivars that could retain the halophytic traits through transgenesis show some promise, further exploration is needed to test the contribution of single or multiple salt stress-related genes or regulatory factors from halophilic plants, including S. alterniflora, for possible utilization in crop improvement.
