Other claims from this paper (15)
- Observation Individual Salicornia plants may have alternative 10.5 and 12 kb rDNA repeat units.
- Association The frequency of Salicornia genetic variants was strongly associated with the tidal inundation gradient.
- Observation Salicornia dolichostachya from low sandy flats was monomorphic for the 12 kb variant.
- Observation S. fragilis from deep creeks was monomorphic for the 12 kb variant.
- Observation S. europaea populations were heterogeneous for rDNA variant type.
- Observation S. ramosissima populations were heterogeneous for rDNA variant type.
- Association The 12 kb variant frequency was significantly higher in Salicornia from lower than upper marsh.
- Association The 12 kb variant frequency was significantly higher in Salicornia from low pans than raised interfluves.
- Association The 10.5 kb variant had the converse spatial distribution to the 12 kb variant.
- Association Salicornia rDNA variation was not obviously associated with morphology.
- Association Salicornia rDNA variation was not obviously associated with previously established isozyme frequencies.
- Association The association between rDNA and environment appeared complex and site-dependent across the sampled regions.
- Observation Salicornia from Anglesey had 10.5 and 11.5 kb variants.
- Observation Only a 10-75 kb variant was detected in Salicornia from Spain and Saudi Arabia.
- Observation rDNA analysis of maternal Salicornia plants and progeny found no evidence of out-crossing.
