</span></p>
<p><span style="font-size:11.0pt;font-family:"Arial",sans-serif;color:black">This week our lab is hosting Dr. Allison Hansen as the next QSB speaker (7Sept.). Dr. Hansen is an assistant professor at the University of California Riverside. Her research focuses
on a broad range of questions that include evolution, genomics, and genetic manipulation of animal-microbe symbioses. Her talk title, abstract, and lab link are attached below.<o:p></o:p></span></p>

<p><span style="font-size:11.0pt;font-family:"Arial",sans-serif;color:black">There are still a few spots for folks to meet and chat with Dr. Hansen.

<p><span style="font-size:11.0pt;font-family:"Arial",sans-serif;color:black">Organelles and host-restricted bacterial symbionts are characterized by having highly reduced genomes that lack many key regulatory genes and elements. Thus, it has been hypothesized
that the eukaryotic nuclear genome is primarily responsible for regulating these symbioses. However, with the discovery of organelle and symbiont expressed small RNAs (sRNAs) there is emerging evidence that these sRNAs may play a role in gene regulation. Here,
we reveal that a conserved antisense sRNA in the model mutualistic aphid endosymbiont genome, Buchnera, is important in post-transcriptional expression of an important protein involved in Arginine biosynthesis; an important symbiont product of the ~200 million-year
obligate symbiosis with its insect host. We further demonstrate that that these conserved Buchnera sRNAs are differentially expressed under different developmental and nutritional environments. These conserved sRNAs are potentially important in regulating
essential amino acid biosynthesis with its insect host.<o:p></o:p></span></p>
