cold tolerance is an adaptative mechanism that plants in temperate climates require to survive and grow in suboptimal temperatures.  exposed plant to low temperature produces a myriad of measurable changes in biochemical characters that are often highly correlated with plant cold tolerance.  a key element of cereal adaptation to cold is represented by the capacity for physiological adjustments ...

this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...

cold stress during the beginning of the season usually causes damage to rice plants in the north of iran. in this study, the expression of four genes namely osp5cs2, osttp1, oscoin and oslti6a, was studied in 14-day-old seedlings of a cold tolerance pr genotype and a cold sensitive hashemi variety during cold stress (5°c for 24h) by means of differential display method. pcr products were quanti...

Floral transition through vernalization has a large influence on cold tolerance and agronomic traits in winter cereals. It is now apparent that in many plants small RNAs play critical roles in determination of the flowering time. There is evidence suggesting that the miR156 and miR172 families play a key role in the flowering transition of plants. In this study, the expression of two temporally ...

abstract due to the growing importance and influence of the self of the teacher in the field of educational and cognitive psychology, the current study intended to investigate the relationship between three teacher qualities and characteristics, i.e. teacher self efficacy, self regulation, and success as perceived by their learners. the study aimed at finding whether teacher self efficacy an...

To understand the gene network controlling tolerance to cold stress, we performed an Arabidopsis thaliana genome transcript expression profile using Affymetrix GeneChips that contain approximately 24,000 genes. We statistically determined 939 cold-regulated genes with 655 upregulated and 284 downregulated. A large number of early cold-responsive genes encode transcription factors that likely co...

Low temperature adversely affects crop yields by restraining plant growth and productivity. Most temperate plants have the potential to increase their freezing tolerance upon exposure to low but nonfreezing temperatures, a process known as cold acclimation. Various physiological, molecular, and metabolic changes occur during cold acclimation, which suggests that the plant cold stress response i...

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...

doi: 10.1111/j.1399-3054.2005.00596.x Cold acclimation involves precise signaling and regulation of the transcriptome. The plasma membrane may be the primary cold-stress sensor, and FRY1/HOS2 inositol polyphosphate 1-phosphatase regulates cytosolic inositol-1,4,5-triphosphate levels, which in turn control cytosolic Ca2þ signatures and cold acclimation. Cold-induced reactive oxygen species may a...
