Decay resistance and extractive content of second-growth Port Orford cedar (Chamaecyparis lawsoniana) wood

Creator:: Ajuong, Elijah, Freitag, Camille, and Morrell, Jeffrey J
Abstract:: Port Orford cedar (Chamaecyparis lawsoniana) has a reputation for being resistant to fungal attack, but much of the work to support this premise used older growth material (80-100 yr old). Given the tendency for the heartwood from the second growth of some species to be less durable, we evaluated the...

Antifungal effects of hinokitiol and its sodium salt for wood protection

Creator:: Li, Shujun, Freitag, Camille M., Morrell, Jeffrey J., and Okabe, Toshihiro
Abstract:: The ability of natural and synthetic hinokitiol, as well as a water soluble derivative (hinokitiol sodium salt), to protect wood against fungal attack was examined. Synthetic and natural hinokitiol provided similar protection. All three materials exhibited similar antifungal activity against Aspergillus niger and Penicillium citrinum on yellow poplar wafers at...

Effect of Copper on Long-Term Performance of Dazomet as an Internal Remedial Treatment in Douglas-Fir Poles

Creator:: Love, Connie S., Freitag, Camille M., and Morrell, Jeffrey J.
Abstract:: A solid, crystalline fumigant (dazomet) with and without a supplemental copper compound was evaluated as an internal decay control treatment on Douglas-fir poles in two long-term field tests. Methylisothiocyanate (MITC), the decomposition product of dazomet, was used as a measure of effectiveness. MITC levels in the wood were above the...

An integrated approach using Bacillus subtilis B26 and essential oils to limit fungal discoloration of wood

Creator:: Wang, Yu, Chang, Jianmin, Morrell, Jeffrey J., Freitag, Camille M., and Karchesy, Joseph J.
Abstract:: Bacillus subtilis and essential oils have been explored separately for their ability to limit colonization by wood stain and mold fungi, but neither approach has been completely effective. One alternative strategy would be to combine the bacterial biocontrol with one or more natural products extracts. In this report, the ability...

A Panel of Histone H3 Mutations to Investigate Centromere Maintenance and Gene Silencing

Creator:: Geisler, Mark S.
Abstract:: Histones, as part of nucleosomes, are responsible for DNA packaging in chromosomes. They also affect DNA expression by a multitude of post-translational modifications, especially prevalent on the amino terminus of histones. Co-activator protein complexes “write”, “read”, or “erase” histone modifications, and in balance determine which sections of DNA are free...

Studies on the centromere-specific histone, CenH3, of Neurospora crassa and related ascomycetes

Creator:: Phatale, Pallavi A.
Abstract:: In eukaryotes, the defined loci on each chromosome, the centromeres, accomplish the critical task of correct cell division. In some organisms, centromeres are composed of a euchromatic central core region embedded in a stretch of heterochromatin and the inheritance and maintenance of centromeres are controlled by dynamic epigenetic phenomena. Although...

A Panel of Histone H3 Mutations to Investigate Centromere Maintenance and Gene Silencing

Creator:: Esposito, Madison L.
Abstract:: Modifications of histone tail amino acid residues are necessary for many reactions involving chromatin. These processes can produce transcriptionally active, euchromatic, or inactive, heterochromatic, segments of DNA. The formation and maintenance of facultative heterochromatin is critical for the proper growth and development of many eukaryotes. Euchromatin can be changed into...

Transcriptional networks controlled by the fatty acid regulators FAR-1 and FAR-2

Creator:: Bredeweg, Erin L.
Abstract:: Fungi are capable of growth on a wide variety of carbon sources, both living and dead. They can produce an arsenal of enzymes and transporters for harvesting sugars, polysaccharides, amino acids, lipids and micronutrients from their environments [1]. Within the nucleus of a cell, transcription factors (TF) control whether genes...

Mutation of Polycomb Repressive Complex 2 (PRC2) kmt6 to Probe in vivo Function in Fusarium

Creator:: Josephson, Brian
Abstract:: Polycomb Repressive Complex 2 (PRC2) is a histone methyltransferase that initiates facultative heterochromatin formation by trimethylating histone H3 on lysine 27 (H3K27me3). Mutations within its three primary subunits, KMT6, EED, and SUZ12, result in inherited diseases and sporadic cancers. In the fungus Fusarium graminearum, deletion of the gene encoding the...
