... Plants can acquire increased freezing tolerance through cold-acclimation involving the ICE1-CBF-COR pathway. Recently, Lee et al. investigated a potential link between the functional activation of CBF and cellular redox state. We propose that redox-mediated CBF activation could be a hub of low temperature as well as light signaling in the cold-acclimation process. ...

Abstract:
... Cryopreservation can help to meet the demand for biosamples of high medical value. However, it remains difficult to effectively cryopreserve some sensitive cells, tissues, and reproductive organs. A coordinated effort from the perspective of the whole frozen biological system is necessary to advance cryopreservation technology. Animals that survive in cold temperatures, such as hibernators and col ...

Abstract:
... For an introduced species to expand its range, individuals must be able to adapt to novel stressors (biotic and abiotic) that they may encounter. Florida has a distinct temperature gradient and rapid climate zone transitions from warmer subtropical regions to cooler temperate regions. Mean minimum temperatures are thought to prohibit northward movement of introduced fish species in south Florida. ...

Abstract:
... AIM: The Arctic is the coldest inhabited region on Earth, and it supports few terrestrial species. The tropical‐climate origin of many angiosperm clades, along with strong phylogenetic niche conservatism, likely constrained colonization of cold environments for many plants. However, invasion of the Arctic by many lineages might also have opened up a new adaptive landscape that facilitated subseque ...

Abstract:
... Physiology is crucial for the survival of invasive species in new environments. Yet, new climatic conditions and the limited genetic variation found within many invasive populations may influence physiological responses to new environmental conditions. Here, we studied the case of the delicate skinks (Lampropholis delicata) invading Lord Howe Island (LHI), Australia. On LHI, the climate is differe ...

Abstract:
... The overwintering capacity of biocontrol agents is of fundamental relevance for biological control of pests in temperate regions. In this study we tested the cold tolerance of the indigenous Drosophila pupal parasitoids Pachycrepoideus vindemmiae and Trichopria drosophilae at constant low temperature in the laboratory and exposed different preimaginal parasitoid stages in the field during winter. ...

Abstract:
... Neotropical black mangrove (Avicennia germinans) is expanding poleward into temperate salt marsh along Atlantic Florida, USA, with field evidence of trait shifts consistent with greater cold tolerance within range margin populations. However, whether these shifts have a genetic basis remains unanswered. To address this gap, we measured multiple phenotypic traits of twenty A. germinans maternal coh ...
... AIM: Mountains harbour a rich and non‐random cluster of species, yet knowledge of the species' biological attributes that support their coexistence in the montane community is limited. Here, we investigated the association of species occurrence on the Tibetan Plateau with their morphological, ecological or evolutionary constraints. LOCATION: Tibetan Plateau (TP). TAXON: Mammals and birds. METHODS: ...

Abstract:
... Markers of freezability allow the selection of ejaculates of good freezability. So far, most investigations were conducted in boars, bulls, rams and horses, with high economic interests triggering the efforts. The progress in dogs is comparably slow. A critical evaluation of the methods requires consideration of practicability, with most labs not even possessing a computer assisted sperm analyser ...

Abstract:
... BACKGROUND: Insects living in unfavorably high or low temperatures are predicted to display a fast or slow life‐history strategy. Here, we examined life histories of fall armyworm (FAW), a globally important invasive species with a broad ecological niche, at five constant temperatures of 13, 19, 25, 31 and 37°C, to study life‐history responses to different temperatures. RESULTS: In our experiment, ...
... The impact of ultraviolet-B (UV-B) treatment on oxidative stress, cold damage, and antioxidant enzymes and the role of the UV-B photoreceptor SlUVR8 in tomatoes during cold storage were investigated. Mature-green tomato fruit were irradiated with 1, 10, or 100 μmol m⁻² s⁻¹ UV-B for 1, 3, or 6 h respectively before cold-storage. The chilling injury index (CI), H₂O₂, O₂⁻, ion leakage, and malondiald ...

Abstract:
... The formation of coherent, three-dimensional (3D) networks by particles either at the interface or in the bulk phase is vital for the stability of emulsions. In this study, nanoparticles of walnut proteins (WPs) were associated by unfolded fibrillar rice proteins (RPs), forming dual protein nanostructures (DPNs) characteristic of coherent 3D networks. The DPNs emulsified walnut oil and formed high ...

Abstract:
... The spatial distribution of biodiversity is driven by species dispersal and their response to the environment. Therefore, diversity patterns should differ across taxonomic groups depending on differences in traits associated with dispersal, metabolism, and foraging. We compared the distribution of rodents and marsupials in the Atlantic forest and investigated how species traits direct their respon ...

Abstract:
... Many weed biological control programs suffer from large-scale spatial variation in success due to restricted distributions or abundances of agents in temperate climates. For some of the world’s worst aquatic weeds, agents are established but overwintering conditions limit their survival in higher latitudes or elevations. The resulting need is for new or improved site- or region-specific biological ...
... Plants are susceptible to a variety of abiotic stresses during the growing period, among which low temperature is one of the more frequent stress factors. Maintaining water balance under cold stress is a difficult and critical challenge for plants. Studies have shown that aquaporins located on the cytomembrane play an important role in controlling water homeostasis under cold stress, and are invol ...

Abstract:
... Apyrase (APY) might regulate the homeostasis of extracellular ATP (eATP) / intracellular ATP (iATP) and mediate plant growth and defense response, but little information on the roles of APY genes in eATP-mediated chilling response of banana fruit during storage has been available. This study identified a total of 10 full-length banana APY genes, analyzed cis-elements in promoters and potential miR ...
... Chemolithoautotrophic production of nitrate is accomplished by the polyphyletic functional group of nitrite‐oxidizing bacteria (NOB). A widely distributed and important NOB clade in nitrogen removal processes at low temperatures is Nitrotoga, which however remains understudied due to the scarcity of cultivated representatives. Here, we present physiological, ultrastructural and genomic features of ...

Abstract:
... MAIN CONCLUSION : ICEs are key transcription factors in response to cold in plant, they also balance plant growth and stress tolerance. Thus, we systematize the information about ICEs published to date. Low temperature is an important factor affecting plant growth and development. Exposing to cold condition results in a suit of effects on plants including reduction of plant growth and reproduction ...

Abstract:
... Cucumbers grafted on rootstocks with different de-blooming capacity show varying levels of cold tolerance. The content of fruit bloom correlates with its silicon-metabolizing capacity, and rootstock grafting can alter not only the cold tolerance but also the silicon-metabolizing capacity of the scion. The molecular mechanisms responsible for resistance due to rootstocks and silicon and the pathway ...
... BACKGROUND: Vegetable grafting has been increasingly evaluated to improve preharvest tolerance to biotic and abiotic stresses. However, very few studies have identified rootstock–scion combinations able to improve fruit shelf life and reduce the susceptibility to postharvest disorders. Herein, a purple eggplant scion (cv. Monarca) was grafted onto a cold‐tolerant hybrid Solanum rootstock (‘Java’) ...
