Starch mobilization in leaves

Starch mobilization is well understood in cereal endosperms, but both the pathway and the regulation of the process are poorly characterized in other types of plant organs. Arabidopsis leaves offer the opportunity for rapid progress in this area, because of the genomic resources available in this species and the ease with which starch synthesis and degradation can be monitored and manipulated. Progress in understanding three aspects of starch degradation is described: the role of disproportionating enzyme, the importance of phosphorolytic degradation, and new evidence about the involvement of a starch‐phosphorylating enzyme in the degradative process. Major areas requiring further research are outline

Project #pstn: engaging pre-service teachers in the Twitterverse

This paper discusses the beginning stages of the #pstn project. #pstn is seeking to introduce pre-service teachers (PSTs) to online networking to help fill in some of those (often huge) gaps between university courses and what actually happens in the classroom. The contribution of this paper is capturing the stories of the research team from very different perspectives around the early stages of #pstn and the insights these stories may hold for the broader practice of encouraging the formation of PLEs within formal education. Insights which suggest the existence of chasms between PSTs and the project members; between the nature of PLEs/PLNs and formal approaches to education; and, the culture of social media for personal and professional reasons. Chasms that need to be explored and bridged before a project like #pstn and perhaps the broader concepts of PLE/PLN can achieve broader success

Analysis of the experimental detection of central nervous system-related genes in human brain and cerebrospinal fluid datasets

Large-scale and high-throughput proteomics experiments of specific samples provide substantial amounts of identified proteins and peptides, which increasingly find their way into centralized, public data repositories. These data typically have potential beyond the analyses performed by the original authors, and can therefore provide considerable added value by being reused for specific, unexplored enquiries. We here reanalyze two CNS-related proteomics datasets, one from the HUPO's Brain Proteome Project, and one from a comprehensive analysis of cerebrospinal fluid in light of the expression of specific splice isoforms from CNS-related genes. We also evaluate the empirically observed peptides of interest against predictions of their proteotypic character
