摘　　要：As sessile organisms,plants must directly face various stressors.Therefore,plants have evolved a powerful stress resistance system and can adjust their growth and development strategies appropriately in different stressful environments to adapt to complex and ever-changing conditions.Nevertheless,prioritizing defensive responses can hinder growth;this is a crucial factor for plant survival but is detrimental to crop production.As such,comprehending the impact of adverse environments on plant growth is not only a fundamental scientific inquiry but also imperative for the agricultural industry and for food security.The traditional view that plant growth is hindered during defense due to resource allocation trade-offs is challenged by evidence that plants exhibit both robust growth and defensive capabilities through human intervention.These findings suggest that the growth-defense trade-off is not only dictated by resource limitations but also influenced by intricate transcriptional regulatory mechanisms.Hence,it is imperative to conduct thorough investigations on the central genes that govern plant resistance and growth in unfavorable environments.Recent studies have consistently highlighted the importance of WRKY transcription factors in orchestrating stress responses and plant-specific growth and development,underscoring the pivotal role of WRKYs in modulating plant growth under stressful conditions.Here,we review recent advances in understanding the dual roles of WRKYs in the regulation of plant stress resistance and growth across diverse stress environments.This information will be crucial for elucidating the intricate interplay between plant stress response and growth and may aid in identifying gene loci that could be utilized in future breeding programs to develop crops with enhanced stress resistance and productivity.
