Abstract: Wood-degrading fungi use a sequence of oxidative and hydrolytic mechanisms to loosen lignocellulose and then release and metabolize embedded sugars. These temporal sequences have recently been mapped at high resolution using directional growth on wood wafers, revealing previously obscured dynamics as fungi progressively colonize wood. Here, we applied secretomics in the same wafer design to track temporal trends on aspen decayed by fungi with distinct nutritional modes: two brown rot-type (BR) fungi (, ) and t… Show more

“…Thus, the production of long‐chain acting enzymes seemed to increase as the pool of hydrolysable polysaccharides was depleted. These results partly agree with the dynamics of enzyme activities in other decomposition experiments (Šnajdr et al ., ; Presley et al ., ).…”

“…First, white-rot fungi have versatile extracellular H 2 O 2 -generating enzymes that participate in the lignin degradation reaction of class II peroxidase, such as aryl-alcohol oxidase (AAO) and glyoxal oxidase (GLOX) (23). The expression of H 2 O 2 -generating enzymes depends on the fungal isolate, wood substrate species, and physiological factors, and different H 2 O 2 -generating enzymes play roles in different stages of fungal decay (40,41). Some H 2 O 2 -generating enzymes, such as glyoxal oxidases, are lacking in some fungi, including Ceriporiopsis subvermispora, Fomitiporia mediterranea, and Heterobasidion annosum, but almost all white-rot fungi reported thus far have contained LPMOs (25).…”

“…Different white-rot species are known to differ in the range of ligninolytic enzymes they are capable of producing (Valmaseda et al 1990;Eastwood et al 2011) and in the identity and activity levels of enzymes expressed over time in relation to the initial capture of wood resource (Presley et al 2018). In addition, white-rot fungi like all saprotrophic microbes secrete a range of hydrolase enzymes as they degrade various carbohydrates in their surroundings and in the search for limiting nutrients (Baldrian 2009).…”

“…These dynamics are not well understood in any dead wood system and have never been examined in pioneer communities. During primary capture of wood resource by the early-secondary decay species T. versicolor and S. hirsutum, activities of laccase and the hydrolases β-glucosidase and β-galactosidase are higher in younger parts of the colony, with hydrolase levels dropping steadily with increasing decomposition (Presley et al 2018). Endochitinase, chitobiosidase and NAG activity levels also increase in older parts of the colony of many species of ligninolytic fungi following primary resource capture of woody resources (Lindahl & Finlay 2006) indicating that hydrolase enzymes associated with N acquisition may increase over decomposition gradients as colonisation times increase.…”
