Plants that previously experienced high but sub\u2010lethal temperatures become subsequently tolerant to higher temperatures through the development of acquired thermotolerance (ATT). ATT activation is associated with the elevated expression of heat shock (HS)\u2010related genes such as <jats:italic>HSFA2<\/jats:italic>, <jats:italic>HSFA3<\/jats:italic>, and <jats:italic>HSP101<\/jats:italic>. Similarly, through the development of systemic acquired resistance (SAR), previously experienced plants achieve a higher resistance than na\u00efve plants. SAR activation requires mobile signals and primarily depends on salicylic acid (SA) signaling. Studies to understand the interaction between ATT and SAR are limiting. To investigate the possible interconnection, we studied cross\u2010protection between SAR and ATT on 4\u2010week\u2010old soil\u2010grown Arabidopsis plants. We observed localized pathogen inoculation provides thermotolerance. Pathogens activate the expressions of <jats:italic>HSFA2<\/jats:italic>, <jats:italic>HSFA3<\/jats:italic>, <jats:italic>HSA32<\/jats:italic>, and <jats:italic>HSP101<\/jats:italic> in pathogen\u2010free systemic tissues. Interestingly, pathogen\u2010induced SAR activation is impaired in <jats:italic>hsfa2<\/jats:italic>, <jats:italic>hsfa3<\/jats:italic>, and <jats:italic>hsp101<\/jats:italic> mutants, suggesting these HS memory genes are essential for SAR induction. In contrast, thermopriming by exposing plants to sublethal temperatures, blocks SAR activation by pathogens. Thermopriming suppresses SAR mobile signal generation, accumulation of SA, and <jats:italic>PR1<\/jats:italic> gene expression in systemic leaves. Altogether, our results demonstrate a complex interaction between SAR and ATT induction pathways in plants.<\/jats:p>","DOI":"10.1111\/pce.15364","type":"journal-article","created":{"date-parts":[[2024,12,31]],"date-time":"2024-12-31T08:05:45Z","timestamp":1735632345000},"page":"3352-3363","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Immune
