Heat stress is a critical challenge to tall fescue (Festuca arundinacea Schreb.) in many areas of the globe and variations in genetic structure and functional traits is for the efficient breeding programs on developing heat tolerant cultivars. Tolerant-related morpho-physiological traits and simple sequence repeat (SSR) markers were employed to survey genetic diversity in greenhouse and growth ...
Identifying and mobilizing useful genetic variation from germplasm banks to breeding programs is an important strategy for sustaining crop genetic improvement. The molecular diversity of 1,423 spring bread wheat accessions representing major global production environments was investigated using high quality genotyping-by-sequencing (GBS) loci, and gene-based markers for various adaptive and qua...
this study attempts to investigate the effect of peers’ revision in comparison to that of the teacher, and whether peers’ comments and teachers’ comments facilitate students’ revision? if yes, which one is more effective? also attempts have been made to see which aspects of language are more highlighted by peers versus teachers when commenting. besides, it is investigating the student’s attitud...
The knowledge of genetic diversity is a must to reduce genetic vulnerability during plant breeding efforts. In the present study 34 pairs microsatellite markers were used for germplasm analysis, estimation of the genetic relationship with the method of Nei and Lee and diversity and studying the capabiltiy of microsatellite marker between 4 resistant and sensitive wheat genotypes. Cluster anal...
of high-quality vegetable and industrial oil. 9 RAPD primers, 6 AFLP primer combinations and 12 agro-morphological traits were used to assess the genetic diversity of 20 accessions of saf flower representing global germplasm variability. Jacquards’ similarity coef ficient were used to understanding the genetic relationships among ccessions, for AFLP and RAPD markers and Euclidian similarity coe...
The tropical maize race Tuxpeño is a well-known race of Mexican dent germplasm which has greatly contributed to the development of tropical and subtropical maize gene pools. In order to investigate how it could be exploited in future maize improvement, a panel of maize germplasm accessions was assembled and characterized using genome-wide Single Nucleotide Polymorphism (SNP) markers. This panel...
Extended Abstract Introduction and Objective: Wild relatives of wheat are one of the most important genetic resources for use in wheat breeding programs. Therefore, identifying wheat wild relatives and Awareness of the diversity in them, also protecting these species is undeniably effective in expanding the richness of the gene pool and the genetic base of new cultivars and can be a good tool ...
a set of 18 simple sequence repeat (ssr) primer pairs was employed to assess the genetic diversity in a collection of 52 melon genotypes that consisted of 24 melon accessions representing different horticultural groups of iranian cultivated melons, along with 28 reference accessions from diverse foreign geographical origins. all the studied ssr loci were polymorphic, confirming their potential ...
Ziziphus is a genus of spiny shrubs and small trees in the Rhamnaceae family. This group has a controversial taxonomy, with more than 200 species described, including Chinese jujube (Ziziphus jujuba Mill. var. jujuba) and Indian jujube (Z. mauritiana), as well as several other important cultivated fruit crops. Using 24 SSR markers distributed across the Chinese jujube genome, 962 jujube accessi...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
