Arabidopsis HDA6 is required for freezing tolerance

Biochemical and Biophysical Research Communications, 2011
Many 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, 2013
Summary 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, 2006
Freeze 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, 1992
The 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 ...

Freezing susceptibility and freezing tolerance in Palaearctic Cetoniidae (Coleoptera)

Canadian Journal of Zoology, 2001
Insects have evolved various adaptations that allow them to survive adverse seasons. In terms of cold-hardiness, they may classically be divided into freezing-susceptible versus freezing-tolerant species. But this concept of two alternative cold-hardiness strategies is now amendable, and to better understand these adaptive mechanisms, it is of ...

Freeze tolerance of forage bermudagrasses

Grass and Forage Science, 2011
AbstractThe 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.

Freezing Tolerance in the Triticeae

2013
Species of the Triticeae tribe of the Poaceae, such as wheat and barley, able to acclimate to and to tolerate frost, are one of the best models for studying freezing tolerance in herbaceous, nonwoody plants. This chapter reviews in detail the genetic and genomic knowledge accumulated over the last twenty years in these model species, in terms of ...

Canalization of freeze tolerance in an alpine grasshopper

Cryobiology, 2015
In 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 ...

Freezing tolerance in Balanus balanoides

Comparative Biochemistry and Physiology Part A: Physiology, 1977
Abstract 1. 1. More than 80% of the body water in Balanus balanoides was frozen at the winter median lethal temperature (MLT—18.6°C). This confirms the suggestion made previously that the mechanism of cold-tolerance in B . balanoides is due to frost resistance rather than avoiding ice formation. 2. 2.

Freeze Tolerance of Seed‐Producing Turf Bermudagrasses

Crop Science, 2002
Bermudagrass, 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
