randomly amplified polymorphic dna (rapd) markers were used to analyze genetic stability of the somatic embryogenesis-derived regenerants (r1-6) and mother plant in iranian date palm (phoenix dactylifera l.) cultivar khanizi. total genomic dna extracted from in vitro fresh leaves of regenerated plants and mother plant was amplified using 10-mer oligonucleotide fermantas primers. four primers of...

genetic diversity of 36 genotypes of dwarf and semi-dwarf apple rootstocks along with seven iranian dwarf rootstocks were investigated by use of rapd dna markers. a set of 100 random primers was utilized in pcr reaction from which 10 primers resulted in good amplification with high polymorphism. among primers, 10 selected rapd primers produced 160 bands, in which, 136 were polymorphic. cluster ...

This investigation was aimed to compare the inference of antelope phylogenies resulting from the 16S rRNA, cytochrome-b (cyt-b) and d-loop segments of mitochondrial DNA using three different computational models including Bayesian (BA), maximum parsimony (MP) and unweighted pair group method with arithmetic mean (UPGMA). The respective nucleotide sequences of three Oryx species (Oryx leucoryx, ...

to assess the genetic diversity for morphological and agronomic traits in iranian oriental tobacco germplasm,100 oriental and semi-oriental tobacco genotypes from the urmieh tobacco research center collection were evaluated in the field using a simple square lattice design with two replications. some agronomic traits were measured on five randomly selected plants in each plot. genotypes were cl...

Rhodiola sachalinensis is an endangered species with important medicinal value. We used inter-simple sequence repeat (ISSR) and methylation-sensitive amplified polymorphism (MSAP) markers to analyze genetic and epigenetic differentiation in different populations of R. sachalinensis, including three natural populations and an ex situ population. Chromatographic fingerprint was used to reveal HPL...

targeted extension for heterogeneous farming systems is a challenge in developing countries. farm type identification and characterization based on estimates of income from different farm components allows simplifying diversity in farming systems. use of multivariate statistical techniques, such as principal component analysis (pca) and cluster analysis (ca), help in such farm typology delineat...
