linked and/or gene-based molecular markers have been used widely in marker-assisted selection (mas) to differentiate resistant and susceptible genotypes. resistance to meloidogyne spp. in beta vulgaris l. is mediated by a single dominant gene (r6m-1). using allele-specific primers (asps), an snp marker harboring a single nucleotide polymorphism (a/g), linked to the resistance gene was developed...

to evaluate the genetic variations in eleven fennel populations in iran, 55 accessions were analyzed by srap markers. twelve primer combinations produced 171 polymorphic bands. the cumulative dendrogram delineated fennel accessions into five major groups in accordance to the geographical regions from which the populations were originated. about 43.57% of total genetic variation was detected amo...

die-back disease caused by paecilomyces variotti is one of the most destructive diseases of pistachio in iran. in this study, genetic diversity of paecilomyces variotti isolates was investigated with ssr marker, using six primers pairs. sampling was done from pistachio gardens in different geographical zones of kerman province during summer 2013. various fungal isolates were isolated from infec...

this article reviews the recently published data on the diagnosis of cancer with proteomics, including the major proteomics technologies and promising strategies for biomarker discovery and development.  most of the tumor markers are proteins that either numerically increase in response to the alteration of cancer conditions or are produced by cancer cells. however, they are natural compounds o...

the study of genetic variation and phylogenetic relationships is essential for the efficient selection of superior plant material and conducting introgression breeding programs. in iran, despite the wide geographical distribution of grasses no report is available on the genetic diversity and relationships of cool season grass populations. in this study amplified fragment length polymorphism (af...

Discovery of molecular markers for efficient identification of living organisms remains a challenge of high interest. The diversity of species can now be observed in details with low cost genomic sequences produced by new generation of sequencers. A method, called c-GAMMA, is proposed. It formalizes the design of new markers for such data. It is based on a series of filters on forbidden pairs o...

In this paper, we describe a novel algorithm to group, label, identify and perform optical tracking of marker sets, which are grouped into two specific configurations, and whose projective invariant properties will allow obtaining a unique identification for each predefined marker pattern. These configurations are formed by 4 collinear and 5 coplanar markers. This unique identification is used ...

This fall marks 20 years since the cloning of unc-119 was reported. Despite having a strong phenotype that makes animals somewhat difficult to grow and handle, unc-119 mutant rescue has become one of the most frequentlyused markers for C. elegans transformation. In this Commentary, I describe the history of how unc-119 rescue traveled through the worm community, contributing to the development ...

This paper provides two puzzles for a theory of aspect. The first concerns the quirky behavior of the Russian imperfective with regard to its culmination properties: it seems to function like the perfect aspect in certain cases, but like the progressive in others. The other puzzle concerns how the Russian imperfective constrains the temporal location of a described event: it relates distinct ev...
