Maize is moderately sensitive to salt stress; therefore, soil salinity is a serious threat to its production worldwide. Here, excellent salt-tolerant maize inbred line TL1317 and extremely salt-sensitive maize inbred line SL1303 were screened to understand the maize response to salt stress and its tolerance mechanisms. Relative water content, membrane stability index, stomatal conductance, chlo...

Salt stress impedes plant growth and disrupts normal metabolic processes, resulting in decreased biomass increased leaf senescence. Therefore, the ability of a to maintain when exposed salinity is critical for production salt tolerant crops. To identify genetic basis tolerance an agronomically important grain crop, we used recombinant inbred line (RIL) population derived from interspecific cros...

Genetic relatedness between individuals is an important measure in many areas of biology. However, some relatedness measures for use with molecular (allele) data assume that the individuals themselves are not inbred. Here, we present a new measure of relatedness based on the different modes of identity-by-descent for alleles that has an upper bound of 1 even when the individuals being compared ...

Enormous advances have occurred in the understanding of the molecular and cellular mechanisms responsible for both collateral development (collaterogenesis*) and atherogenesis. This advancement has been accompanied by parallel advances in therapies designed to enhance collaterals and to inhibit the development and progression of atherosclerosis. Our laboratory has been interested in both areas,...

the laboratory mouse is recognized as the pre-eminent model for genetic research. awareness of chromosomal patterns of experimental animals increases their value for a variety of different fields of study. we aimed to study mitotic chromosome preparations from nih, c57bl/6 and razi strains of mice, which are outbred, inbred and partially inbred laboratory mice respectively. bone marrow cells we...

the objective of the present study was to evaluate the effects of inbreeding on average daily gains and kleiber ratios in moghani sheep. traits included average daily gain from birth to 3 months (adg1), average daily gain from birth to 6 months (adg2), average daily gain from 3 months to 6 months (adg3), average daily gain from 3 months to 9 months (adg4), average daily gain from 3 months to ye...

Background: Downy mildew caused by Plasmopara halstedii is one of the most devastating diseases of sunflower worldwide. So far several dominant resistance genes designated as Pl have been identified and their molecular markers linked to these genes are available. However, no information on the resistance genes is available in Iranian lines. Objective: In this study, the presence of three map-b...
