Physiological and molecular changes in plants grown at low temperatures

Area of Science:

• Plant science
• Environmental stress biology
• Molecular plant physiology

Background:

• Low temperature is a major environmental factor limiting plant productivity and distribution.
• Plants possess physiological and molecular adaptations to tolerate cold stress.
• Cold acclimation is a key process enabling plants to survive low temperatures.

Purpose of the Study:

• To review recent research on plant cold perception mechanisms.
• To explore the physiological and molecular changes in plants exposed to low temperatures.
• To emphasize the regulation of cold-induced gene products during acclimation.

Main Methods:

• Literature review of current research on plant cold stress.
• Analysis of physiological and molecular adaptation strategies.
• Focus on transcriptional, post-transcriptional, and post-translational regulation.

Main Results:

• Plants perceive cold through various mechanisms.
• Cold perception triggers metabolic adjustments and gene product regulation.
• Multiple layers of regulation contribute to cold acclimation.

Conclusions:

• Cold acclimation involves complex perception and response pathways.
• Understanding these pathways is crucial for improving plant cold tolerance.
• Gene product regulation plays a significant role in plant survival under cold stress.
