Unveiling links between phytohormone and abiotic stress signaling

Signal integration is essential for organisms to fine-tune their growth, development, and stress responses. Phytohormones, serving as endogenous signals, play important roles in mediating various processes in response to environmental cues. Extensive research to date in genetics and molecular biology has uncovered the central regulators of phytohormone signaling, such as receptors, protein kinases, and transcription factors. Here, recent advances in how these phytohormone signaling pathways mediate environmental signals are highlighted, especially focusing on newly identified components and their links with the core regulators under abiotic stress conditions. With particular interests in transcriptional readouts, how environmental signaling impacts the perception and signal transduction of phytohormones and their interactions are discussed.
