“…It is widely considered that SA plays a vital role in plant stress tolerance to a wide range of abiotic stresses [140,141], including low-temperature or cold stress [37][38][39]118]. In response to cold stress, SA can regulate plant metabolism and induce the biosynthesis of cold-resistant proteins, thus improving plant tolerance to low-temperature stresses.…”

“…According to Malko et al, the use of multiple chemicals, including SA, Zn, polyamines (PA), sodium nitroprusside (SNP), etc., with pre-and post-emergence treatment, has enhanced drought tolerance and maintained the normal physiology of wheat under changing climates [34]. According to Lafuente and Romero, citrus fruits' heat-induced cross-adaptation to chilling is regulated by phytohormones such as JA, JA-related metabolites, SA, IAA, and ABA [39]. According to Wei et al, SA and auxin exerted antagonistic regulatory effects on the transcripts of the MeHsf8-MeHSP90.9 module, which is closely related to plant immunity.…”

“…It is generally held that SA plays vital roles in plant stress tolerance. SA's main roles in plant tolerance to stresses can be summarized as following: the activation of plant defense mechanisms [2,[11][12][13][14], the improvement of photosynthesis [15][16][17][18][19][20][21][22], the regulation of plant normal growth and development [8,19,[23][24][25][26][27][28][29][30], and the enhancement of plant tolerance to drought [9,11,[31][32][33][34][35][36], cold [37][38][39], heat [36,[39][40][41][42], salt [43][44][45][46][47][48], and heavy metal stresses [49][50][51]…”
