Phylogenetic analysis of endophytic bacterial isolates from leaves of the medicinal plant Trichilia elegans A. Juss. (Meliaceae)

S. A. Rhoden, Garcia, A., Silva, M. C. Santos e, Azevedo, J. L., and Pamphile, J. A., Phylogenetic analysis of endophytic bacterial isolates from leaves of the medicinal plant Trichilia elegans A. Juss. (Meliaceae), vol. 14, pp. 1515-1525, 2015.

Various organisms such as fungi and bacteria can live inside plants, inhabiting the aerial parts (primarily the leaves) without causing damage. These microorganisms, called endophytes, produce an extensive variety of compounds that can be useful for medical and agronomic purposes. Trichilia elegans A. Juss., belonging to the Meliaceae family, shows wide dispersion in South America, and phytochemical analyses from these plants and endophyte isolates have shown biological activity.

Selection of DNA barcoding loci for Nepeta deflersiana Schweinf. ex Hedge from chloroplast and nuclear DNA genomes

F. Al-Qurainy, Khan, S., Nadeem, M., Tarroum, M., and Gaafar, A. R. Z., Selection of DNA barcoding loci for Nepeta deflersiana Schweinf. ex Hedge from chloroplast and nuclear DNA genomes, vol. 13, pp. 1144-1151, 2014.

Molecular markers, mainly DNA-based are potential tools for DNA barcoding and phylogenetic study. The plant species belonging to the Nepeta genus have important medicinal value because of the presence of nepetalactones, and they have been used to treat human diseases. We amplified nuclear and chloroplast gene loci to develop a DNA barcode and phylogenetic study of Nepeta deflersiana.

Development of genetic markers for Ochradenus arabicus (Resedaceae), an endemic medicinal plant of Saudi Arabia

S. Khan, Al-Qurainy, F., Nadeem, M., and Tarroum, M., Development of genetic markers for Ochradenus arabicus (Resedaceae), an endemic medicinal plant of Saudi Arabia, vol. 11, pp. 1300-1308, 2012.

Some species of the genus Ochradenus are difficult to identify based on morphological markers. Similar limitations are found for biochemical markers. We developed genetic markers based on DNA sequences for Ochradenus arabicus, which is an endemic plant to Saudi Arabia, locally utilized as a medicinal shrub. The internal transcribed spacer sequence of nuclear ribosomal DNA and chloroplast (rpoB and rpoC1) markers were more informative than other chloroplast DNA markers.

Genetic variation of Kaempferia (Zingiberaceae) in Thailand based on chloroplast DNA (psbA-trnH and petA-psbJ) sequences

J. Techaprasan, Klinbunga, S., Ngamriabsakul, C., and Jenjittikul, T., Genetic variation of Kaempferia (Zingiberaceae) in Thailand based on chloroplast DNA (psbA-trnH and petA-psbJ) sequences, vol. 9, pp. 1957-1973, 2010.

Genetic variation and species authentication of 71 Kaempferia accessions (representing 15 recognized, six new, and four unidentified species) found indigenously in Thailand were examined by determining chloroplast psbA-trnH and partial petA-psbJ spacer sequences. Ten closely related species (Boesenbergia rotunda, Gagnepainia godefroyi, G. thoreliana, Globba substrigosa, Smithatris myanmarensis, S. supraneanae, Scaphochlamys biloba, S. minutiflora, S.
