genetic diversity amongst 21 induced mutant clones tolerant to salinity along with one non-irradiated sensitive clone of banana (musa acuminata cv. dwarf cavendish (aaa)) were studied using morphological and random amplified polymorphic dna (rapd) markers. out of the 30 phenotypic indices screened, 23 were polymorph and two traits, leaf habit and blotches color, were differentiated by non-irrad...

in order to identify the segre qtl affecting growth traits on the end region of chromosome 18 in a lori-bakhtiari sheep population, 162 animals from 5 paternal half-sib families were taken to be studied. phenotypic data included records of birth weight (bwt), weight at one month of age (w1), weaning weight (wwt), weight at six months of age (w6), chest circumference (gi6), body length (lg6), wi...

Sex determination in the Nile tilapia (Oreochromis niloticus) is thought to be an XX-XY (male heterogametic) system controlled by a major gene. We searched for DNA markers linked to this major locus using bulked segregant analysis. Ten microsatellite markers belonging to linkage group 8 were found to be linked to phenotypic sex. The putative Y-chromosome alleles correctly predict the sex of 95%...

in order to genetic analysis of rice seed vigour, a cross was carried out between tarom mahalli (tolerant to osmotic stress) and khazar (sensitive to osmotic stress) crosses. linkage map based on ssr markers was derived using 74 polymorphic markers and 192 f2 individuals. germination rate, radicale and plumule length were recorded from 20 plants per 192 f3 families. the loci related to germinat...

low- temperature (lt) tolerance is an economic trait in winter wheat that determines the plants’ ability to successfully cope with below freezing temperatures. to identify the genomic regions associated with lt tolerance in hexaploid wheat, an f2:3 population was produced from crossing between winter type and tolerant parent, mirnovoskaja 808 (lt50 = -20oc), and spring type and susceptible pare...

We have previously demonstrated that long-term exposure of bovine tracheal smooth muscle (BTSM) strips to insulin induces a functional hypercontractile phenotype. To elucidate molecular mechanisms by which insulin might induce maturation of contractile phenotype airway smooth muscle (ASM) cells, we investigated effects of insulin stimulation in serum-free primary BTSM cell cultures on protein a...

The aim of this study was to evaluate the genetic diversity sour cherries using SSR markers, correlate data with phenotypic traits, and investigate suitability Prunus-specific microsatellite markers in species. Nineteen cherry genotypes from Fruit Research Institute Érd, Hungary, were analyzed twelve primer pairs. number alleles ranged two ten, a mean value 4.67 per locus. highest generated BPP...

Brassica mustard species represent one of the most important oilseed crops in India, nevertheless, their genetic diversity is barely known. A better understanding on this topic is essential for the proper utilization of genotypes in breeding programmes. We evaluated the genetic diversity among 44 Indian mustard (Brassica juncea) genotypes including varieties/purelines from different agro-climat...

Genotypic or phenotypic markers for characterization of natural populations of marine microalgae have typically addressed questions regarding differentiation among populations, usually with reference to a single or few clonal isolates. Based upon a large number of contemporaneous isolates from the same geographical population of the toxigenic species Alexandrium tamarense from the North Sea, we...
