In a striking contrast, matK is one of the most rapidly evolving plastid genes and also one of the few plastid genes to be retained in all nonphotosynthetic plants examined to date. DNA sequences of this region were obtained from photosynthetic and nonphotosynthetic plants of Orobanchaceae and their relatives. The resulting plastid DNA phylogeny was congruent with that recently obtained from an...

Panax vietnamensis was discovered recently in Vietnam. Its bamboo-like rhizomes, called Vietnamese Ginseng, have attracted considerable attention because of their specific pharmacological activities. In order to define the taxonomic position of this new species and include it in the molecular authentication of Ginseng drugs, the 18S ribosomal RNA gene and matK gene sequences of P. vietnamensis ...

Charophytes (Charales) are benthic algae with a complex morphology. They are vulnerable to ecosystem changes, such as eutrophication, and are red-listed in many countries. Accurate identification of Chara species is critical for understanding their diversity and for documenting changes in species distribution. Species delineation is, however, complicated, because of high phenotypic plasticity. ...

Stelechocarpus merupakan salah satu genus anggota famili Annonaceae yang tumbuh di kawasan Asia-Pasifik. Sebagai tumbuhan kurang dikenal oleh masyarakat maka perlu adanya upaya konservasi karena jenis mempunyai banyak manfaat bidang farmasi dan kosmetika. Salah strategi mendukung yaitu dengan DNA barcoding masih sedikit informasinya untuk Stelechocarpus. Penelitian ini bertujuan mengevaluasi lo...

Nucleotide sequence polymorphisms of the intron of the chloroplast trnK (UUU) gene, including a matK gene, were investigated within two wild Fagopyrum species, F. leptopodum and F. statice, to assess the degree and pattern of the inter- and intraspecific differences in coding and noncoding chloroplast DNA regions in higher plants. Ten and five accessions were used for F. leptopodum and F. stati...
