Tubulin sequence divergence is associated with the use of distinct microtubule regulators.

Diverse eukaryotic cells assemble microtubule networks that vary in structure and composition. While we understand how cells build microtubule networks with specialized functions, we do not know how microtubule networks diversify across deep evolutionary timescales. This problem has remained unresolved because most organisms use shared pools of tubulins for multiple networks, making it difficult to trace the evolution of any single network.

Development of a robust SNP marker set for genotyping diverse gene bank collections of polyploid roses.

Background: Due to genetic depletion in nature, gene banks play a critical role in the long-term conservation of plant genetic resources and the provision of a wide range of plant genetic diversity for research and breeding programs. Genetic information on accessions facilitates gene bank management and can help to conserve limited resources and to identify taxonomic misclassifications or mislabelling. Here, we developed SNP markers for genotyping 4,187 mostly polyploid rose accessions from large rose collections, including the German Genebank for Roses.

Distinct Strategies Regulate Correlated Ion Channel mRNAs and Ionic Currents in Continually versus Episodically Active Neurons.

Relationships among membrane currents allow central pattern generator (CPG) neurons to reliably drive motor programs. We hypothesize that continually active CPG neurons utilize activity-dependent feedback to correlate expression of ion channel genes to balance essential membrane currents. However, episodically activated neurons experience absences of activity-dependent feedback and, thus, presumably employ other strategies to coregulate the balance of ionic currents necessary to generate appropriate output after periods of quiescence.

What are the perceived unmet needs for patient care, education, and research among genitourinary cancer nurses in Australia? A mixed method study.

Objective: Specialist genitourinary (GU) nurses provide care to a broad and diverse group of patients diagnosed with kidney, bladder, prostate, testicular, adrenal, and penile cancer. The purpose of this study was to identify GU cancer nurse perspectives of perceived unmet needs in service provision, specific educational and research priorities.

Methods: A concurrent mixed methods study design incorporated quantitative and qualitative data collection from the GU Cancer nurses workforce in Australia.
