Arabidopsis HDA6 is required for freezing tolerance
Biochemical and Biophysical Research Communications, 2011Many plants exhibit altered gene expression patterns in response to low nonfreezing temperatures and an increase in freezing tolerance in a phenomenon known as cold acclimation. Here we show, for the first time, that the histone deacetylase gene HDA6 is required for cold acclimation and freezing tolerance in Arabidopsis.

Avoidance and tolerance of freezing in ectothermic vertebrates
Journal of Experimental Biology, 2013Summary Ectothermic vertebrates have colonized regions that are seasonally or perpetually cold, and some species, particularly terrestrial hibernators, must cope with temperatures that fall substantially below 0°C. Survival of such excursions depends on either freeze avoidance through supercooling or freeze tolerance.

Physiological responses to freezing in hatchlings of freeze-tolerant and -intolerant turtles
Journal of Comparative Physiology B, 2006Freeze tolerance is a complex cold-hardiness adaptation that has independently evolved in a diverse group of organisms, including several ectothermic vertebrates. Because little is known about the mechanistic basis for freeze tolerance in reptiles, we compared responses to experimental freezing in winter-acclimatized hatchlings representing nine taxa ...

Cryomicroscopic analysis of freezing in liver of the freeze-tolerant wood frog
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1992The technique of directional solidification coupled with low-temperature scanning electron microscopy was applied to analyze the freezing of liver slices from the freeze-tolerant frog Rana sylvatica. Micrographs of liver slices from 5 degrees C-acclimated frogs frozen on the directional stage to -7 degrees C showed continuous ice formed along an ...

Freeze Tolerance of Seed‐Producing Turf Bermudagrasses
Crop Science, 2002Bermudagrass, Cynodon dactylon (L.) Pers., suffers periodic severe winter‐kill throughout much of its area of use in the contiguous USA. A research goal is to increase freeze tolerance in cultivars to lessen the risk of such damage. An identified research need is for Cynodon germplasm resources to be characterized for freeze tolerance and hybridization

Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1999
In this paper we present the results of physiological responses to winter acclimation and tissue freezing in a freeze-tolerant Siberian earthworm, Eisenia nordenskioeldi, and two freeze-intolerant, temperate earthworm species, Lumbricus rubellus and Aporrectodea caliginosa. By analysing the physiological responses to freezing of both types we sought to

Freeze tolerance of forage bermudagrasses
Grass and Forage Science, 2011AbstractThe ability to survive harsh winters is one of the primary factors limiting bermudagrass (Cynodon spp.) distribution, especially those used for forage. Consequently, improved stress tolerance has been a goal of programmes for breeding bermudagrasses.

Canalization of freeze tolerance in an alpine grasshopper
Cryobiology, 2015In the Rock and Pillar Range, New Zealand, the alpine grasshopper, Sigaus australis Hutton, survives equilibrium freezing (EF) all-year round. A comparison of freeze tolerance (FT) in grasshoppers over four austral seasons for a 1 year period finds that: (a) the majority (>70%) of the sample population of grasshoppers survive single freeze-stress ...

Tolerance for Freezing in Hatchling Turtles
Journal of Herpetology, 1999-Hatchling painted turtles (Chrysemys picta), Blanding's turtles (Emydoidea blandingi), slider turtles (Trachemys scripta), and snapping turtles (Chelydra serpentina) were inoculated with ice at temperatures near the equilibrium freezing point for their body fluids (ca. -0.7 C) and then frozen at -2.0 C.

What Contributes to Freeze Tolerance?
Physiology, 1987Unique among vertebrates, some frogs withstand freezing of the whole body during overwintering. How can they tolerate complete stoppage of breathing, heartbeat, and blood flow when the animal freezes, to start again on thawing? They provide a fascinating view of life in a frozen state and offer a model system for possible medical use in organ ...
