description Water temperature significantly affects the physiological balance of aquatic organisms like crustaceans, and heat shock proteins (HSPs) are crucial for stress resistance and pathogen defense. This study conducted a genome-wide analysis to explore the functional characteristics of the <i>Hsp70</i> gene family in <i>Procambarus clarkii</i>. Fifteen <i>Hsp70</i> family members were identified, with several genes showing upregulation under non-lethal heat shock (NLHS) and pathogen challenges. RNA-Seq and qPCR analyses confirmed increased expression of certain <i>PcHsp70s</i> during NLHS, indicating NLHS activation of the <i>Hsp70</i> family to enhance immune regulation. dsRNA-mediated silencing of <i>Hsp70</i> led to downregulation of TLR pathway genes (e.g., <i>TLR1</i>, <i>TLR6</i>), suggesting <i>Hsp70</i> regulates the TLR signaling pathway for immune responses. These findings reveal that NLHS-induced <i>Hsp70</i> upregulation improves pathogen resistance, offering insights for addressing temperature fluctuations and disease outbreaks in aquaculture to optimize management practices.
