this experiment was conducted to determine the effect of vitamin c (vc) and coenzyme q10 (coq10) onimmunity response of broilers in cold stress condition using 500 male chicks in a completely randomizeddesign with 5 treatments and five replicates. treatments were: positive control (pc, normal conditionsgrowth without antioxidants), negative control (nc, cold stress without antioxidants), cold s...

rice plants are injured at the seedling stage in early spring in northern iran. in order to study rice response to cold stress, the expression of osdreb1a, osap37, osmyb3r-2, and osnac6 genes encoding transcription factors was observed in 14-day-old seedlings of cold-tolerant genotype pr and cold-sensitive cv. hashemi during cold stress (5°c for 24 h) using the differential display method and t...

objective: the present study aimed to determine whether castration altered osmotically stimulated vasopressin (vp) release and urinary volume and what is the role of endocrine-stress axis in this process. materials and methods: totally 108 mice were studied in two main groups of castrated (n=78) and control (n=30). each group was extracted by acute cold stress (4◦c for 2h/day), restraint stress...

abiotic stress such as cold and drought has adverse effects on plants growth and development. abiotic stress resistance is one of the most important goals in plant breeding. this goal can be achieved through transcription factor gene transfer to plants. recent studies show many successes in improving abiotic stress resistance by use of transcription factor gene transfer. the objective of the re...

compound of 5-aminolevulinic acid (5-ala) has herbicide behavior in high concentration. while, it acts as growth regulator at low concentrations and causes resistance to various stresses incluing cold and salibity. therefore the exogenous application of 5-aminolevulinic acid was investigated to induce cold stress tolerance in young soybean plants (glycine max l.). the experiment was conducted a...

Cold stress is an ‎important limiting factor for cereal production. Barley is a host species for arbuscular mycorrhizal fungi (AMF) with a high genetic diversity in response to cold stress. In order to explore the mechanisms for the ameliorative effect of AMF under cold stress, an experiment was undertaken using completely randomized block design with three factors including temperature treatme...
