Genome-Wide Association Studies and Transcriptome Changes during Acclimation and Deacclimation in Divergent Brassica napus Varieties. [PDF]

Int J Mol Sci, 2020
Information concerning genes and signals regulating cold acclimation processes in plants is abundant; however, less is known about genes and signals regulating the deacclimation process. A population of primarily winter B.

Ice Nucleation and Freezing Consequences in Perennial Plants. [PDF]

Physiol Plant
ABSTRACT The precise location where ice forms in plants affects the physical constraint it exerts on the different biological compartments (cells, tissues, organs). It is therefore critical to understand where and how ice nucleates to predict the extent of low temperature damage.

Vessel development in compound buds of interspecific hybrid grape induced by artificial deacclimation treatments [PDF]

, 2023
application/pdfGrape compound buds adapt to subfreezing temperatures in winter by supercooling, but the supercooling ability is thought to be lost upon formation of xylem connections between canes and buds. It was reported that compound buds of the Vitis

Reduced snow cover at the alpine treeline: resistance and recovery of saplings. [PDF]

New Phytol
Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

Local Adaptation for Seasonal Cold Tolerance in a High-Elevation Conifer Species, Subalpine Larch (<i>Larix lyallii</i> Parl.). [PDF]

Evol Appl
ABSTRACT Subalpine larch (Larix lyallii Parl.) is a deciduous conifer that only grows at treeline in the Cascade Range and Rocky Mountains of western North America. This habitat is shrinking due to climate change but subalpine larch is unlikely to migrate or adapt in situ and is therefore at risk of maladaptation and eventual extirpation.

Cold Hardiness Dynamics and Spring Phenology: Climate-Driven Changes and New Molecular Insights Into Grapevine Adaptive Potential

Frontiers in Plant Science, 2021
Climate change has become a topic of increasing significance in viticulture, severely challenged by this issue. Average global temperatures are increasing, but frost events, with a large variability depending on geographical locations, have been ...

Functional and metabolomic analyses of brown adipose tissue during cold-deacclimation reveal rapid N-acetylated amino acid adaptations. [PDF]

iScience
Non-shivering thermogenesis (NST) in brown adipose tissue (BAT) is rapidly activated in the cold but inactive at warm ambient temperatures. To elucidate the metabolic remodeling in BAT during recovery from cold exposure, mice were acclimated to 4°C for 7

Cold Acclimation and Deacclimation of Two Garden Rose Cultivars Under Controlled Daylength and Temperature

Frontiers in Plant Science, 2020
Low temperature stress is an important abiotic stress for garden roses in northern regions. Two garden rose cultivars (‘Dagmar Hastrup’ and ‘Chandos Beauty’) were selected to study the role of dehydrin and of carbohydrate metabolism during cold ...

Transcriptional and Post-Transcriptional Regulation and Transcriptional Memory of Chromatin Regulators in Response to Low Temperature

Frontiers in Plant Science, 2020
Chromatin regulation ensures stable repression of stress-inducible genes under non-stress conditions and transcriptional activation and memory of stress-related genes after stress exposure.
