Plant Signaling Hormones and Transcription Factors: Key Regulators of Plant Responses to Growth, Development, and Stress.

Summary

This review paper examines the role of plant signalling hormones and transcription factors as central regulators of plant physiology, development, and stress tolerance. The authors synthesise molecular evidence on how these regulatory systems coordinate plant responses to growth signals, developmental cues, and environmental stressors such as drought, salinity, and pathogen challenge. The work contributes to foundational understanding of the molecular basis for crop performance variation under diverse growing conditions.

UK applicability

This foundational review has broad applicability to UK crop production, particularly in understanding how crops might adapt to increasingly variable climate conditions. Knowledge of hormone and transcription factor regulation underpins plant breeding and agronomic strategies to improve resilience in UK farming systems.

Key measures

Molecular signalling pathways; transcription factor function; hormone-mediated gene expression; stress-response mechanisms

Outcomes reported

The paper reviews the molecular mechanisms by which plant signalling hormones (including auxins, gibberellins, cytokinins, abscisic acid, and ethylene) and key transcription factors regulate plant growth, development, and adaptive responses to environmental stress. It likely synthesises current understanding of how these regulatory systems coordinate physiological and developmental processes.
