siRNA Screening: Development of Hit Stratification Strategies
Žaklina Strezoska, Annaleen Vermeulen, Emily M. Anderson, Anja Smith, Devin Leake

This poster compares different approaches to hit stratification and validation after an initial screen. Standard siRNA reagents deconvoluted from a pooled set of four were compared to a pooled set of four specificity enhanced reagents. High confidence hits were similar. To explore the validity of low confidence hits, a chimeric approach was used whereby a gene-specific seed sequence was introduced into a non-targeting siRNA scaffold. This work resulted in new hit stratification strategies.

Stable Chloroplast: Myth or Reality?
Shailesh Joshi and Dyfed Evans

Chloroplasts principally encode the photosynthetic machinery in Viridiplantae. It has long been accepted that in photosynthetic plants chloroplast genomic structure is uniquely stable as it is maternally and clonally inherited. The first chloroplast genomes sequenced supported this view. The current study was undertaken to address the potential issue of global chloroplast(in)stability.

Accurate Normalization of Grain Samples Using Pressure-Based Volume Measurement Technology
Bill Gigante, John Thomas Bradshaw, Tanya Knaide

A common challenge experienced by sample screening facilities is identifying individual sample quantity prior to DNA extraction. Accurately identifying sample quantity allows the user to pipette exact amounts of extraction buffer into each well.
