Abstract: Background: Averrhoa carambola L. (star fruit) is an underutilized plant in the family Oxalidaceae. The has various pharmacological activities and fleshy juicy fruit with high nutritional value rich vitamins. Objectives: This study aims to authenticate examine evolutionary relationships between taxa. Materials Methods: species identification was verified using well-established DNA bar...

A new species, Aporosa tetragona Tagane & V. S. Dang, sp. nov., is described and illustrated from Mt. Hon Ba located in the Khanh Hoa Province, South Vietnam. This species is characterized by tetragonal pistillate flowers and fruits, which are clearly distinguishable from the other previously known species of the genus. The morphology and phylogeny based on rbcL and matK of this species indicat...

Most of the plant species from genus Momordica which originated Asia and Africa have been shown to functional value, both as food medicinal plants. However, quality utilization plants needs be controlled through accurate authentication, for example molecular analysis based on DNA barcodes. The matK sequence is one most widely used barcode regions in studies. Therefore, this study was conducted ...

Phylogenetic reconstruction in the Poaceae began early in this century with proposed evolutionary hypotheses based on assessment of existing knowledge of grasses (e.g., Bew, 1929; Hubbard 1948; Prat, 1960; Stebbins, 1956, 1982; Clayton, 1981; Tsvelev, 1983). Imperical approaches to phylogenetic reconstruction of the Poaceae followed those initial hypotheses, starting with cladistic analyses of ...

Although the matK gene has been used in addressing systematic questions in four families, its potential application to plant systematics above the family level has not been investigated. This paper examines the rates, patterns, and types of nucleotide substitutions in the gene and addresses its utility in constructing phylogenies above the family level. Eleven complete sequences from the GenBan...

Casuarinaceae are a Gondwanic family with a unique combination of morphological characters not comparable to any other family. Until recently, the 96 species in the family were classified in a single genus, Casuarina s.l. A recent morphological revision of the family resulted in the splitting of Casuarina s.l. into four genera-Allocasuarina, Casuarina s.s., Ceuthostoma, and Gymnostoma. This stu...
