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