frost tolerance of winter wheat depends primarily on a strong vernalization requirement, delaying the transition to reproductive phase. the responses of four bread wheat cultivars (triticum aestivum l.) to low-temperatures were examined in controlled environment and field conditions. prolonged cold treatment accelerated the transition to reproductive development in winter wheats (cv. norstar an...

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...

Low temperature is a major factor limiting rice productivity and geographical distribution. Improved cold tolerance and expanded cultivation to high-altitude or high-latitude regions would help meet growing rice demand. Here we explored a QTL for cold tolerance and cloned the gene, CTB4a (cold tolerance at booting stage), encoding a conserved leucine-rich repeat receptor-like kinase. We show th...

Relation between cold stress and mortality The general cold stress and mortality related to cold seen at temperatures below 0°C in Yekaterinburg, and their absence at temperatures above 0°C, can be most easily explained by a causal relation between mortality and cold stress. These results reinforce those of our earlier study, which showed an association between cold stress and mortality among d...

Currently, cold temperatures are one of the main factors threatening rapeseed production worldwide; thus, it is imperative to identify cold-resistant germplasm and to cultivate cold-resistant rapeseed varieties. In this study, the cold resistance of four Brassica rapa varieties was analyzed. The cold resistance of Longyou6 and Longyou7 was better than that of Tianyou2 and Tianyou4. Thus, an F2 ...

Calreticulin is an abundant endo/sarcoplasmic reticulum Ca2+-binding protein. To investigate whether calreticulin (CRO1) is involved in the cold-stress response in rice, a transgenic plant was constructed. The transcriptional level was decreased within 30 min and recovered within 2 h of a cold treatment. The calreticulin protein was shifted from a soluble fraction to an insoluble fraction by co...

This prospective, randomized study evaluated continuous-flow cold therapy for postoperative pain in outpatient arthroscopic anterior cruciate ligament (ACL) reconstructions. In group 1, cold therapy was constant for 3 days then as needed in days 4 through 7. Group 2 had no cold therapy. Evaluations and diaries were kept at 1, 2, and 8 hours after surgery, and then daily. Pain was assessed using...

UNLABELLED • PREMISE OF THE STUDY Cold tolerance is a critically important factor determining how plants will be influenced by climate change, including changes in snowcover and extreme weather events. Although a great deal is known about cold tolerance in Arabidopsis thaliana, it is not highly cold tolerant. This study examined cold tolerance and its genetic diversity in an herbaceous subarc...

In suspension-cultured tobacco (Nicotiana tabacum) cells, we have often encountered cold-stable microtubules (MTs). The cold-stable MTs were found in the pelleted fraction of tobacco cell homogenates. These cold-stable MTs were shown to be accompanied by unidentified filamentous structures that extended along part of their length. However, during the early hours in culture such cold-stable MTs ...

Low temperature or cold stress is one of the major abiotic stresses for rice production and productivity in temperate rice-growing regions as well as in tropical highlands worldwide. Low temperature at the reproductive stage causes high sterility and decreases production of elite rice cultivars. In this study, we used F7–8 recombinant inbred lines (RILs) which had cold-tolerance genes/quantitat...
