“…How the different pathways, networks, and hormones that regulate each of the plant responses to stress interact with each other, and how these interactions are regulated during a stress combination, are mostly open questions that await further research. There are many examples of signal transduction and hormone interactions in plants, including the integration of light and heat, or light and pathogen, signaling via different light receptors (e.g., [64]), the antagonistic functions of different plant hormones such as JA and SA (e.g., [45]), or the impact of epigenetic control over the activation of particular stress-response pathways (e.g., [65,66]). The identification of unique transcriptional regulators (transcription factors, TFs) and quantitative trait loci (QTLs) associated with stress combinations should begin to uncover some answers (e.g., [38][39][40]44,[47][48][49][50][51][52]).…”
