Metallothionein (MT) is important because it binds tightly to heavy metals to decrease their toxicity. DNA was isolated from 30 toxic metal exposed and 30 toxic metal unexposed Zebu cows. The amplified metallothionein isoform-2 (MT-2) PCR product (489 bp) was further used for PCR-RFLP and DNA sequencing. MT-2 TaqI PCR-RFLP revealed homozygous genotype (AA) except for the E23 animal (AB). The ge...

Background: Simple sequence repeats (SSRs) are 1 - 6 bp repeat motif sequences present across both prokaryotic and eukaryotic genomes with various clinical implications besides being tools for conservation evolutionary studies. Objectives: Analysis of 33 Coronavirus genomes, including severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), incidence, distribution, complexity SSRs patterns...

Background: Many plant growth-promoting bacteria including Rhizobia contain the 1-aminocyclopropane-1-carboxylate (ACC) deaminase enzyme that can leave ACC, and thereby lower the level of ethylene in stressed plants. Drought and salinity are the most common environmental stress factors for plants in Iran. Objectives: The main aim of this research was development of bio-fertilizers containing A...

cattle have an important role in primary human civilization, so molecular studies for more accurate recognition of their origin are effective to identify unknown historical aspects. cattle can be divided in to 2 main groups including bos tuarus and bos indicus. both types of cattle can be found in iran; therefore study of their origin has particular importance. the aim of this study was to inve...

introduction camels belong to the family of camelidae, suborder of tylopoda, order of artiodactyla and class of mammalians. the family camelidae has two old world species, double-humped camel (camelus bactrianus) and single-humped camel (camelus dromedaries) and four new world (tribe lamini) species, guanaco (lama guanicoe), llama (lama glama), alpaca (lama pacos) and vicuna (lama vicugna or vi...
