Estimation of genetic diversity and evaluation of plant germplasm is the most important step in collection and management of plant genetic resources. Also, comparison of different DNA-based genetic markers in diversity evaluation and then advising the most efficient markers is very important. In order to investigate genetic variation among Persian oak (Quercus brantii Lindi.) populations of Lor...

Genetic maps with high genome coverage are becoming increasingly useful in both basic and applied genetic researches. In the last decades, the advent of DNA markers has brought about a magnificent revolution in the production of genetic map, especially in wheat. In the present study, AFLP markers were used to saturate linkage map of 107 doubled haploid individuals produced through Fukuho _Komug...

Extended Abstract Introduction: Capparis spinose is from Capparis genus, and Capparidaceae family includes 350 species. It is originated from Mediterranean region. Human as food uses entire parts of C. spinose as young stems, flower buds, fruit, and seed. Caper, trade name, has several species in Iran.

In the current investigation, 10 IRAP, 14 REMAP, 16 ISSR and 7 SSR primers and mixed linear model (MLM)-based association analysis were used to identify molecular markers associated with 13 morphological traits in cultivated alfalfa (Medicago sativa L.). Morphological traits studied, were height, chlorophyll content, total wet weight, total dry weight, wet leaf weight, dry leaf weight, wet stem...

This study aimed to investigate the use of interactional metadiscourse markers in 168 comments made by 28 university students of engineering via an educational forum held as part of a general English course. The students wrote their comments on six topics, with a total of 19,671 words. Their comments during educational discussions were analyzed to determine their use of five metadiscourse categ...

Metadiscourse markers help writers make coherent and reader- friendly texts, thus of considerable importance in academic writing. The main aim of this study was to investigate how interactive and interactional metadiscourse markers are used by Iranian EFL learners. An inquiry was carried out to investigate cross-cultural similarities and differences in the use of metadiscourse markers in the Di...

Finding association between molecular markers and agronomic traits provides an excellent tool for indirect selection of a trait of interest in the population. In this study, stepwise regression analysis was used to estimate associations between ISSR and RAPD markers with some agronomic traits in 12 lemon balm ecotypes. Markers or bands were considered as independent variables and traits were co...

The extracts of Piper sarmentosum, a medicinal plant, are being used to prepare phytopharmaceuticals while the information about chemical kinetics of constituents of the extract is unavailable to assign precise shelf life (t90) and find optimum storage conditions of the product for patient safety, and to avoid economic repercussions of launching an unstable product. The extract was exposed to t...
