  • Descrição: Random amplified polymorphic DNA (RAPD) markers are used to estimate interspecific variation among mangrove and non-mangrove Heritiera fomes, H. littoralis and H. macrophylla. All the species have 2n =38 chromosomes, with minute structural changes distinguishing the karyotype of each species. Significant variation of 4C DNA content occurs at the interspecific level. Interspecific polymorphism ranged from 14.09% between H. fomes and H. littoralis to 52.73% between H. fomes and H. macrophylla. H. macrophylla showed wide polymorphism in the RAPD marker with H. littoralis (51.23%) and H. fomes (52.73%) . Two distinct RAPD products obtained from OPA-10 (1000 bp) and OPD-15 (900 bp) found characteristic molecular markers in H. macrophylla, a species from a non-mangrove habitat. H. macrophylla was more distantly related to H. fomes[genetic distance (1-F)=0.305] than to H. littoralis[genetic distance (1-F)=0.273]. H. littoralis was of a closer affinity to H. fomes[genetic distance (1-F)=0.218] than to H. macrophylla.
