“…At the end of his career Barton was critical of the way university courses were being geared towards learning about accounting standards and practical techniques. He believed that undergraduate accounting should focus on teaching students to think analytically and that there was a place for economics in accounting education (Sexton, 2003).…”

“…It must be remembered, though, that Barton never considered these roles as separate. He argued that 'good teachers need to be good researchers to remain at the forefront of knowledge in their disciplines' and that practical experience was imperative for good teaching and research (Sexton, 2003). Nor did Barton believe that accounting can be taught in intellectual isolation; the close relationship between accounting and economics was an example of the synergy of interdisciplinary relationships that enhance their individual relevance to real-world issues.…”

Biography is now established as a valid form of research in the accounting history literature and there have been calls for biographic work that goes beyond the focus on practitioners, early academics and theorists to consider those who have made other kinds of contribution. As a member of the Australian Accounting Hall of Fame, Allan Douglas Barton's contribution is notable for its breadth and depth. Barton played a critical role in the growth of accounting as a discipline distinct from economics. He was also important in the growth of academic communities in Adelaide, Sydney and Canberra. In addition, he reflected a strong commitment to spanning theory and practice through significant service in University leadership, diverse committee work and extensive engagement in public policy and reform. This biographic study of Barton provides a template for future work considering a broader and multifaceted contribution spanning theory and practice, research and leadership, reflection and policy.

Pectin Methylesterase Genes Influence Solid Wood Properties of Eucalyptus pilularis

This association study of Eucalyptus pilularis populations provides empirical evidence for the role of Pectin Methylesterase (PME) in influencing solid wood characteristics of Eucalyptus. PME6 was primarily associated with the shrinkage and collapse of drying timber, which are phenotypic traits consistent with the role of pectin as a hydrophilic polysaccharide. PME7 was primarily associated with cellulose and pulp yield traits and had an inverse correlation with lignin content. Selection of specific alleles in these genes may be important for improving trees as sources of high-quality wood products. A heterozygote advantage was postulated for the PME7 loci and, in combination with haplotype blocks, may explain the absence of a homozygous class at all single-nucleotide polymorphisms investigated in this gene.

Single nucleotide polymorphisms in a cellulose synthase gene (PtoCesA3) are associated with growth and wood properties in Populus tomentosa

In plants, the composition and organization of the cell wall determine cell shape, enable cell expansion, and affect the properties of woody tissues. Cellulose synthase (CesA) genes encode the enzymes involved in the synthesis of cellulose which is the major component of plant primary and secondary cell walls. Here, we isolated a full-length PtoCesA3 cDNA from the stem cambium tissue of Populus tomentosa. Tissue-specific expression profiling showed that PtoCesA3 is highly expressed during primary cell wall formation. Estimation of single nucleotide polymorphism (SNP) diversity and linkage disequilibrium (LD) revealed that PtoCesA3 harbors high SNP diversity (π(T) = 0.00995 and θ(w) = 0.0102) and low LD (r(2) ≥ 0.1, within 1,280 bp). Association analysis in a P. tomentosa association population (460 individuals) showed that seven SNPs (false discovery rate Q < 0.10) and five haplotypes (Q < 0.10) were significantly associated with growth and wood properties, explaining 4.09-7.02% of the phenotypic variance. All significant marker-trait associations were validated in at least one of the three smaller subsets (climatic regions) while five associations were repeated in the linkage population. Variation in RNA transcript abundance among genotypic classes of significant loci was also confirmed in the association or linkage populations. Identification of PtoCesA3 and examining its allelic polymorphisms using association studies open an avenue to understand the mechanism of cellulose synthesis in the primary cell wall and its effects on the properties of woody tissues.
