Shaping Plant Adaptation in a Warmer World: Developmental Plasticity Under Moderately Elevated Temperatures

Area of Science:

• Plant Biology
• Climate Change Adaptation
• Developmental Plasticity

Background:

• Rising global temperatures due to climate change significantly affect plant growth and productivity.
• While extreme heat stress is well-studied, the effects of moderate temperature increases on plant development are less understood.
• Plants, as sessile organisms, utilize developmental plasticity to adapt to environmental changes, including temperature fluctuations.

Purpose of the Study:

• To review current knowledge on how moderately elevated temperatures regulate plant developmental plasticity across the entire life cycle.
• To understand the mechanisms of moderate warmth perception and signal transduction in plants.
• To explore the coordination and trade-offs between vegetative and reproductive growth under warming conditions.

Main Methods:

• Literature review of recent advances in plant thermobiology and developmental plasticity.
• Synthesis of findings on temperature sensing pathways and their impact on plant development.
• Analysis of adaptive strategies and breeding approaches for climate resilience.

Main Results:

• Moderate temperatures influence developmental plasticity during both vegetative and reproductive phases.
• Plants possess mechanisms to perceive and respond to moderate warmth, adjusting growth accordingly.
• Coordination between growth phases is essential for overall plant fitness under changing temperatures.

Conclusions:

• Understanding plant responses to moderate heat is vital for predicting agricultural impacts of climate change.
• Developmental plasticity is a key trait for plant adaptation to warming environments.
• Targeting developmental plasticity offers a promising strategy for breeding climate-resilient crops.
