“…Decomposer nutritional modes affect CO 2 evolution and organic inputs to the soil (Berg and McClaugherty, 2008), as well as carbon content, metalbinding, redox, permeability, and sorption in resulting residues (Ryp a cek and Ryp a ckov a, 1975; Gilbertson, 1980;Jurgensen et al, 1997;Filley et al, 2002;Song et al, 2012;Harmon et al, 2013). Fungal mycelial networks further connect above-with belowground pools and create an avenue for element translocation into and out of deadwood (Ostrofsky et al, 1997;Boddy, 1999;Connolly et al, 1999;Liew and Schilling, 2012). This capacity for a rotting log to be an element sink, as well as an element source, will affect its suitability as a nurse log (Harmon and Franklin, 1989) and its ability to buffer stands against element losses through leaching, etc., thus contributing to overall forest health (e.g., exchangeable Ca, Shortle and Smith, 1988;Shortle et al, 2012).…”

“…Hastrup et al (2006) treated SP with 1.2% CC and showed 4.8% mass loss by G. trabeum at week 10. Liew and Schilling (2012) reported similar effects of copper CuE-treated and micronized copper quaternary-treated wood on G. trabeum by week 12 (4.9 and 2.1% mass loss, respectively). Jenkins et al (2014) also found copper sensitivity of G. trabeum on 1.2% CC-treated wood at weeks 2 and 4; however, there was no copper sensitivity when SP was not pressure-treated with copper (i.e., dipped in copper, adjacent to copper).…”

Gene Expression Analysis of Three Putative Copper-Transporting ATPases in Copper-Tolerant Fibroporia radiculosa

Copper tolerance of brown-rot basidiomycete decay fungi can lessen the efficacy of copper-containing wood preservatives for wood products in-service. The purpose of this study was to evaluate wood mass loss and differential expression of three genes that have putative annotations for copper-transporting ATPase pumps (FIBRA_00974, FIBRA_04716, and FIBRA_01430). Untreated southern pine (SP) and SP treated with three concentrations of ammoniacal copper citrate (CC, 0.6, 1.2, and 2.4%) were exposed to two copper-tolerant Fibroporia radiculosa isolates (FP-90848-T and L-9414-SP) and copper-sensitive Gloeophyllum trabeum isolate (MAD 617) in a 4-week-long standard decay test (AWPA E10-19). Decay of copper-treated wood was inhibited by G. trabeum (p = 0.001); however, there was no inhibition of decay with increasing copper concentrations by both F. radiculosa isolates. Initially, G. trabeum and one F. radiculosa isolate (L-9414-SP) highly upregulated FIBRA_00974 and FIBRA_04716 on copper-treated wood at week 1 (p = 0.005), but subsequent expression was either not detected or was similar to expression on untreated wood (p = 0.471). The other F. radiculosa isolate (FP-90848-T) downregulated FIBRA_00974 (p = 0.301) and FIBRA_04716 (p = 0.004) on copper-treated wood. FIBRA_01430 expression by G. trabeum was not detected, but was upregulated by both F. radiculosa FP-90848-T (p = 0.481) and L-9414-SP (p = 0.392). Results from this study suggest that all three test fungi utilized different mechanisms when decaying copper-treated wood. Additionally, results from this study do not provide support for the involvement of these putative gene annotations for copper-transporting ATPase pumps in the mechanism of copper-tolerance.

“…Bakrov oksalat je v vodi zelo slabo topen in zato za glive praktično nestrupen. Med glivami razkrojevalkami se toleranca najpogosteje pojavlja pri sivi hišni gobi (Serpula lacrymans), beli hišni gobi (Fibroporia vaillantii) in drugih glivah tega rodu (Steenkjaer Hastrup et al, 2005;Liew & Schilling, 2012;Karunasekera et al, 2017).…”

Les na prostem je izpostavljen delovanju abiotskih in biotskih dejavnikov. Če hočemo njihovo delovanje upočasniti, moramo les zaščititi. V preteklosti je bil biocidni proizvod na osnovi bakrovih, kromovih in borovih spojin (CCB) ena najpomembnejših rešitev za zaščito lesa v ostrih pogojih izpostavitve. Kljub temu, da se CCB v EU praktično ne uporablja več, lahko služi kot referenca za vrednotenje novih biocidnih proizvodov. Na terenskem polju Oddelka za lesarstvo Biotehniške fakultete že 14 let poteka poskus v realnih pogojih, kjer so impregnirani vzorci izpostavljeni vremenskim vplivom v skladu z dvoslojnim testom. Pri zaščitenem lesu pogosto opažamo, da les propade hitreje kot je pričakovano. V okviru tega prispevka želimo na podlagi analize razkrojenega s CCB impregniranega lesa s terenskega polja Oddelka za lesarstvo ugotoviti, zakaj je prišlo do prezgodnjega razkroja. Rezultati kažejo, da ustrezno življenjsko dobo zagotavljata ustrezna retencija in penetracija aktivnih učinkovin v les.
