Abstract: Exogenous adenosine triphosphate (ATP) treatment at 0, 250, 500, 750, and 1000 µM retarded cap browning in mushrooms by 0, 34, 26, 51 and 32 %, respectively, during storage at 4 °C for 18 days. Triggering signaling H <subscript>2</subscript> O <subscript>2</subscript> accumulation arising from elevating NADPH oxidase enzyme activity during 6 days of storage at 4 °C may be pivotal for promoting shikimate dehydrogenase enzyme activity in mushrooms treated with ATP during 18 days of storage at 4 °C. Promoting melatonin accumulation (390 µg kg <superscript>-1</superscript> FW vs. 160 µg kg <superscript>-1</superscript> FW) in mushrooms treated with ATP during cold storage may attribute to signaling H <subscript>2</subscript> O <subscript>2</subscript> accumulation. Higher DPPH scavenging capacity (72 % vs. 65 %) in mushrooms treated with ATP may attribute to higher phenols accumulation arising from higher phenylalanine ammonialyase/polyphenol oxidase enzymes activity concomitant with higher alternative oxidase gene expression during 18 days of storage at 4 °C.<br /> (Copyright © 2019 Elsevier Ltd.
