Callose structure

LPS also has effects on cell wall alterations such as callose deposition (Keshavarzi et al., 2004) and on PR gene induction (Zeidler et al., 2004 Silipo et al., 2005). In some cases specific effects of a particular LPS on plant gene induction are observed. LPS from the crucifer pathogen Xcc induced expression of a gene encoding a defense-related (->-(1 -3) glucanase when applied to turnip leaves at 1 p,g per ml. In contrast, LPS from Escherichia coli and Salmonella enterica were ineffective at concentrations up to 50 p,g per ml (Newman et al., 1995). Such specific effects may reflect the ability of particular plants to recognize structural features within LPS that are not widely conserved.

Structural Studies Patients with antisocial personality disorder have been shown to have reduced prefrontal gray matter volumes (Raine et al., 2000). In addition, these individuals exhibit abnormalities in the corpus callosum (Raine et al., 2003), showing an increased callosal length and white matter volume, but a decreased thickness. They also showed evidence of increased functional efficiency of interhemispheric interaction, which was not, however, associated with their anatomical measures. Raine et al. interpreted their results as indicative of either abnormal white matter pruning or increased myelination in the callosum. 

Structural/functional abnormalities have been shown in frontal, temporal and parietal cortical regions, basal ganglia, callosal areas and cerebellum.

The development of highly sensitive proteomic methods for the characterization of membrane-bound proteins should facilitate the systematic sequencing of all the proteins that are present in fractions with high callose synthase activity. Also, the progress made on in vitro synthesis of cellulose is promising and proteomic analysis may also be used on fractions enriched in cellulose synthases in the near future. This approach combined with detailed structural characterization of in vitro products, immunochemical methods, molecular biology and gene...
