K., Analysis of the genetic diversity of super sweet corn inbred lines using SSR and SSAP markers, vol. 15, p. -, 2016.

In this study, we compared the efficiency of simple sequence repeat (SSR) and sequence specific amplified polymorphism (SSAP) markers for analyzing genetic diversity, genetic relationships, and population structure of 87 super sweet corn inbred lines from different origins. SSR markers showed higher average gene diversity and Shannon’s information index than SSAP markers. To assess genetic relationships and characterize inbred lines using SSR and SSAP markers, genetic similarity (GS) matrices were constructed.

Genetic relatedness of artichoke (Cynara scolymus L.) hybrids using random amplified polymorphic DNA (RAPD) fingerprinting

M. A. Sharaf-Eldin, Al-Tamimi, A., Alam, P., Elkholy, S. F., and Jordan, J. R., Genetic relatedness of artichoke (Cynara scolymus L.) hybrids using random amplified polymorphic DNA (RAPD) fingerprinting, vol. 14, pp. 18431-18439, 2015.

The artichoke (Cynara scolymus L.) is an important food and medicinal crop that is cultivated in Mediterranean countries. Morphological characteristics, such as head shape and diameter, leaf shape, and bract shape, are mainly affected by environmental conditions. A molecular marker approach was used to analyze the degree of polymorphism between artichoke hybrid lines. The degree of genetic difference among three artichoke hybrids was evaluated using random amplified polymorphic DNA-PCR (RAPD-PCR).

Application of DNA barcoding markers to the identification of Hopea species

N. T. P. Trang, Duc, N. M., Sinh, N. V., and Triest, L., Application of DNA barcoding markers to the identification of Hopea species, vol. 14, pp. 9181-9190, 2015.

Hopea chinensis (synonym: H. hongayensis) (Dipterocarpaceae) is a threatened species found so far in only two locations: Quang Ninh (Vietnam) and Guangxi (China). The species shares many morphological characteristics with H. mollissima and the two species are often confused. To overcome this problem of identification and to investigate the genetic relationships of Hopea species with other Dipterocarp species, we sequenced three candidate DNA barcodes for the chloroplast markers rbcL, trnH-psbA, and matK.
