We evaluated the efficiency of the touchdown method to determine the ideal PCR conditions for distinct inter-simple sequence repeat primers for processing DNA from common corn, popcorn, sweet corn, and a Tripsacum-maize hybrid. Genomic DNA was extracted from eight accessions of corn: two of the dent type, one Tripsacum-maize h.. Read More»

Eucommia ulmoides Oliver, one of the tertiary relict species found only in China, is the only extant species of Eucommiaceae. Using inter-simple sequence repeat (ISSR) and sequence-related amplified polymorphism (SRAP) markers, we studied the genetic diversity and population genetic structure of 187 accessions from 17 E. ulmoides populations throughout it..

In order to investigate genetic diversity and population structure of Ceratoides arborescens, six populations were selected from different steppe types in Inner Mongolia grasslands of China. Intersimple sequence repeat (ISSR) markers were used to assess the genetic diversity within and among natural populations of C. arborescens. Thirteen ISSR primers gen.. Read More»

Considering the expected genetic variability of elephant grass (Pennisetum purpureum), due to its cultivation in different continents, we characterized and estimated the genetic divergences between 46 accessions of elephant grass with different edaphoclimatic adaptations, using RAPD and ISSR markers. We evaluated, comparativel.. Read More»

Bioactive oils extracted from sea buckthorn (Hippophae rhamnoides) berries contain highly nutritional and medicinal compounds; however, the oil contents of sea buckthorn berries are very low. Thirteen inter-simple sequence repeat (ISSR) primers were used to identify markers associated with oil content of dry pulp in 51 cultivars and lines, which clustered.. Read More»

Genetic relationships of 17 Rhododendron cultivars, China, were assessed using inter-simple sequence repeat (ISSR) and amplified fragment length polymorphism (AFLP) markers. A total of 133 bands were obtained using nine selected ISSR primers, 129 (96.99%) of which were polymorphic; 267 bands were amplified by four AFLP primer pairs, 251 (94.01%) of which .. Read More»

Mangaba (Hancornia speciosa Gomes) is found in areas of coastal tablelands in the Brazilian Northeast and Cerrado regions. This species has been subjected to habitat fragmentation that is mainly due to human activity, and requires conservation strategies. The aim of this study was to analyze the structure and inter- and intrapopulation genetic diversity o.. Read More»

Isolates of entomopathogenic fungus Metarhizium anisopliae var. anisopliae were characterized using internal transcribed spacer-RFLP, ISSR and intron splice site primers. Thirty-seven isolates were studied, most of which were obtained from the sugar cane pest, Mahanarva fimbriolata (Hemiptera: Cercopidae) from Tangará d.. Read More»

Diploid Thinopyrum elongatum, a wild relative of wheat, contains many agronomically desirable traits and has potential for increasing genetic variability and introducing desirable characters in this crop. Few molecular markers are available for rapid screening of T. elongatum genome segments in the wheat genetic background. We.. Read More»

The olive tree is an iconic tree of the Mediterranean, and is used extensively to produce high-quality olive oil. Although the China olive industry has just begun to be valued, there were also existed mislabeling and synonyms in introduced cultivars. The aim of this study was to analyze genetic similarities among olive cultivars in China using SSR and ISS.. Read More»
