Abstract
Endogenous formaldehyde is generated as a normal metabolite via bio-catalysis of γ-glutamyl transpeptidase (GGT) and L-cysteine sulfoxide lyase (C-S lyase) during the growth and development of Lentinula edodes. In this study, we investigated the mRNA and protein expression levels, the activities of GGT and C-S lyase, and the endogenous formaldehyde content in L. edodes at different growth stages. With the growth of L. edodes, a decrease was found in the mRNA and protein expression levels of GGT, while an increase was observed in the mRNA and protein expression levels of C-S lyase as well as the activities of GGT and C-S lyase. Our results revealed for the first time a positive relationship of formaldehyde content with the expression levels of Csl (encoding Lecsl) and Lecsl (C-S lyase protein of Lentinula edodes) as well as the enzyme activities of C-S lyase and GGT during the growth of L. edodes. This research provided a molecular basis for understanding and controlling the endogenous formaldehyde formation in Lentinula edodes in the process of growth.
