Sains Malaysiana, 2011;40:1341-1344.

Sejumlah 51 takson pteridofit yang tergolong dalam 30 genus dan 18 famili telah direkodkan di Hutan Simpan Angsi, Negeri Sembilan. Ini termasuk lapan spesies lokofit dalam dua genus dan dua famili. Jumlah ini merangkumi lapan peratus daripada 647 spesies yang telah dilaporkan di Semenanjung Malaysia. Famili terbesar yang direkodkan terdiri daripada Selaginellaceae dan Pteridaceae masing-masing dengan tujuh spesies diikuti oleh Polypodiaceae (enam spesies) dan Tectariaceae (empat spesies). Paku-pakis terestrial merupakan yang paling banyak direkodkan iaitu 60% daripada keseluruhan takson yang didapati diikuti dengan paku pakis epifit (24%) dan paku pakis batuan (16%).

PREMISE OF THE STUDY: Twenty-seven nuclear microsatellite markers were developed for the mangrove fern, Acrostichum aureum (Pteridaceae), to investigate the genetic structure and demographic history of the only pantropical mangrove plant.
METHODS AND RESULTS: Fifty-six A. aureum individuals from three populations were sampled and genotyped to characterize the 27 loci. The number of alleles and expected heterozygosity ranged from one to 15 and 0.000 to 0.893, respectively. Across the 26 polymorphic loci, the Malaysian population showed much higher levels of polymorphism compared to the other two populations in Guam and Brazil. Cross-amplification tests in the other two species from the genus determined that seven and six loci were amplifiable in A. danaeifolium and A. speciosum, respectively.
CONCLUSIONS: The 26 polymorphic microsatellite markers will be useful for future studies investigating the genetic structure and demographic history of of A. aureum, which has the widest distributional range of all mangrove plants.
