Brassinosteroids negatively regulate barley deacclimation tolerance via modulation of chloroplast gene expression and cell hydration. [PDF]

Sci Rep
Global warming may cause overwintering plants to lose tolerance to low temperatures owing to de-acclimation caused by winter temperature fluctuations. The effect of elevated temperatures is regulated by the endogenous levels of phytohormones, including ...

Single-node cuttings for budbreak phenotyping in grapevine [PDF]

BIO Web of Conferences
Budbreak is a critical stagein terms of vulnerability tospring frost, a major issue accentuated by the advancement of grapevine development due to global warming. Recognizing the determinants of budbreak regulation is essential to allow the selection, or

Models for Estimating the Cold Hardiness of Sweet Cherry (Prunus avium cv. Sweetheart and Lapins) in Cold Climate Regions

HortScience, 2023
Plant cold hardiness is a dynamic process, and seasonal changes occur through cold acclimation and deacclimation to help prevent lethal injury from the cold.

Living on the edge – physiological tolerance to frost and drought explains range limits of 35 European tree species

Ecography, EarlyView.
Species distribution models are key to evaluate how climate change threatens European forests and tree species distributions. However, current models struggle to integrate ecophysiological processes. Mechanistic models are complex and have high parameter requirements.

Daily hot‐water immersion preserves altitude‐induced haemoglobin mass expansion following descent independent of erythropoietin

Experimental Physiology, EarlyView.
Abstract High‐altitude exposure increases haemoglobin mass (Hbmass), a key determinant of arterial oxygen‐carrying capacity, but following descent this adaptation can regress toward baseline within 7 days. Long‐term heat acclimation has emerged as an alternative stimulus for Hbmass expansion; however, whether post‐altitude passive‐heat exposure can ...

Tetralone-ABA enhances winter cold acclimation, reduces deacclimation, and delays budbreak in V. vinifera and V. hybrid grapevines

Plant Stress
Climate change-related acute winter freezes and unseasonal false springs have become significant and predictable risks for grape growers across North America and Eurasia.

Effect of Cold Acclimation and Deaссlimation on the Content of Soluble Carbohydrates and Dehydrins in the Leaves of Winter Wheat [PDF]

Journal of Stress Physiology & Biochemistry, 2019
In this work, we studied the influence of cold acclimation (first stage – 8 °С/2 °С for 10 days and second stage – subsequence action of -2 °С for 10 days) and deacclimation (10 °С for 2 days) on the content of soluble carbohydrates and the synthesis of ...

Mechanisms of haemoglobin mass expansion following heat stress

The Journal of Physiology, EarlyView.
Abstract figure legend Theorised mechanisms of heat stress‐induced erythropoiesis which may facilitate the expansion of haemoglobin mass. A, acute: heat stress‐induced renal ischaemia. Redistribution of blood flow away from the kidneys to facilitate thermoregulation during heat stress could reduce renal oxygen delivery, subsequently lowering renal PO2${
