Jan's new paper on red algal cellulose synthases is out!

The Samuels lab is very happy to announce that Jan Xue and her co-authors have just published their work on red algal cellulose synthases in the Journal of Experimental Botany. This paper is the result of Jan's MSc thesis work completed in the Samuels and Martone labs at UBC. In addition Jan travelled to, and collaborated with, the Zimmer lab at the university of Virginia. Jan and her co-authors have combined phylogenetic analysis, heterologous expression, biochemical assays and fluorescent microscopy to further our understanding of cellulose synthases in Calliarthron tuberculosum. Read the paper here.

Dr. Livingston's Graduation!


A couple of stalked glandular trichomes with lovely compartments of terpenes and cannabinoids (for further details on that read the lovely paper here) stopped by the blog to congratulate Dr. Sam Livingston in advance of his PhD. graduation tomorrow. The Samuels lab is very happy for his success and though he will be missed we look forward to the great things he will surely accomplish next.

Congratulations to Sam for his PhD defense

The Samuels lab is very happy to announce that Sam Livingston defended his his PhD thesis successfully today. We congratulate him on his success and the advances he has made to the study of cannabis trichome development and structure. Sam used a wide variety of techniques including immuno fluorescence microscopy, high-pressure-freezing based cryofixation, immuno-TEM microscopy and multiphoton microscopy to study the cannabis trichomes. Sam has been able to describe the subcellular organization of organelles in the secretory cells with previously unattainable detail and quality of preservation. Sam has also made important discoveries in the makeup and development of the cell walls that ultimately hold the important metabolites such as THCA, CBDA and terpenes within the trichomes. Some of Sam's thesis work has already been published in The Plant Journal here.
