Rapid transcriptional and metabolic regulation of the deacclimation process in cold acclimated Arabidopsis thaliana [PDF]

BMC Genomics, 2017
During low temperature exposure, temperate plant species increase their freezing tolerance in a process termed cold acclimation. This is accompanied by dampened oscillations of circadian clock genes and disrupted oscillations of output genes and metabolites.

Cold hardiness dynamics predict budbreak and associated low-temperature threats in grapevine. [PDF]

New Phytol
Summary Dormant buds of temperate woody perennial plants must attain cold hardiness to survive winters and timely lose it in spring to break bud while avoiding damage from low temperatures and late frosts. Therefore, we asked: Can a cold hardiness model be used to predict budbreak?

Cold hardiness mechanisms and modeling: existing approaches and future avenues. [PDF]

New Phytol
Summary Cold hardiness models are useful tools to predict cold damage in plants, such as those produced by unseasonal temperature cycles or by increased cold exposure. Although development of these models started about five decades ago, their applications remain limited.

How Does Diurnal and Nocturnal Warming Affect the Freezing Resistance of Antarctic Vascular Plants? [PDF]

Plants (Basel), 2023
The Antarctic Peninsula has rapidly warmed up in past decades, and global warming has exhibited an asymmetric trend; therefore, it is interesting to understand whether nocturnal or diurnal warming is the most relevant for plant cold deacclimation.

Memory in the wall: expanding our understanding of the roles of plant cell walls. [PDF]

New Phytol
Summary The plant cell wall, while providing mechanical support to cells, also dynamically adjusts its composition and structure in response to cellular and environmental cues. Recent findings indicate that plants exposed to cold stress alter the composition of cell wall polysaccharides and that this altered status primes the plants to overcome future,

Integrative Comparative Assessment of Cold Acclimation in Evergreen and Deciduous Iris Species. [PDF]

Antioxidants (Basel), 2022
Cold acclimation (CA) is a strategy which plants have evolved to increase freezing tolerance. Global climate change could obstruct CA and raise the probability of winter injury, especially for evergreens.

Is It Cold Enough? Effects of Artificial and Natural Chilling on Budbreak and Frost Hardiness in Acer saccharum (Marsh.). [PDF]

Physiol Plant
ABSTRACT A crucial part of the phenological cycle in temperate and boreal trees is the exposure to chilling temperatures releasing endodormancy, which allows the trees to react to external signals and resume growth in spring. We compared the effect of artificial and natural chilling on endodormancy break and frost hardiness of sugar maple (Acer ...

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

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

Front Plant Sci, 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 ...

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.
