The roots of 7-d seedlings of two winter wheat cultivars differing in frost resistance were used to study changes in lectin activity using the inhibitor of microtubule polymerization oryzalin (15 μM) in unhardened (23oC) and hardened (2–3oC, 3–7 d) plants. Plants were grown with the antagonist of calmodulin, chlorpromazine (250 μM) or without chlorpromazine in medium. It was shown that the dyna...

Cold stress significantly constrains the growth, development, productivity, and distribution of rice, particularly indica cultivar, known for its susceptibility to cold, limiting cultivation specific regions. This study investigated genes associated with cold responsiveness in roots two cultivars, SQSL (cold-tolerant) XZX45 (cold-susceptible), through transcriptome dynamics analysis during seed...

lead (pb) is one of the most hazardous heavy metal that caused serious problems for ecosystem at recent years. in this study, the effect of pb on seed germination, incipient growth and antioxidant enzymes of six common used turfgrasses was investigated. the results showed that after implementation of different concentrations (0, 1000, 2000 and 3000 µm) of pb, agropyron elongatum exhibited the h...

Disaster-tolerant systems are complex and expensive constructions that have hitherto been the provision of only the very rich or the very scared. The current state of the art for surviving site-wide failures is to mirror persistent storage to a remote location and cold-start applications there in the event of failure. This requires delicate, tailored modifications to production software to rest...

Tilapia is an important fish cultured in tropical and subtropical areas. Cold sensitivity limits the expansion of tilapia culture into colder regions of the world, and mass mortalities of cultured tilapia have been reported due to severe cold currents in winter. Since the late 1990s, several strains of Nile tilapia have been domesticated to improve the ability to adapt to low temperatures. Prev...

Camellia is a well-known ornamental flower native to Southeast of Asia, including regions such as Japan, Korea and South China. However, most species in the genus Camellia are cold sensitive. To elucidate the cold stress responses in camellia plants, we carried out deep transcriptome sequencing of 'Jiangxue', a cold-tolerant cultivar of Camellia japonica, and approximately 1,006 million clean r...

Many insects, including the model holometabolous insect Drosophila melanogaster, display remarkable plasticity in chill tolerance in response to the thermal environment experienced during development or as adults. At low temperatures, many insects lose the ability to regulate Na(+) balance, which is suggested to cause a secondary loss of hemolymph water to the tissues and gut lumen that concent...

We used mRNA differential display to assess yeast gene expression under cold or freeze shock stress conditions. We found both up- and down-regulation of genes, although repression was more common. We identified and sequenced several cold-induced genes exhibiting the largest differences. We confirmed, by Northern blotting, the specificity of the response for TPI1, which encodes triose-phosphate ...

The ability to rapidly respond to changes in temperature is a critical adaptation for insects and other ectotherms living in thermally variable environments. In a process called rapid cold hardening (RCH), insects significantly enhance cold tolerance following brief (i.e., minutes to hours) exposure to nonlethal chilling. Although the ecological relevance of RCH is well-established, the underly...

A population of 146 RILs (Recombinant Inbred Line) was derived from the cross between a cold-sensitive cultivated Solanum lycopersicum L. XF98-7 and a cold-tolerant wild Solanum pimpinellifolium LA2184. Relative germination ratio (RGR) and chilling index (CI) were used to evaluate the cold tolerance of the parental lines and RILs. It was found that the RGR and CI were significantly different be...
