Laurent Deluc: Associate Professor in plant genomics - Principal Investigator of the lab. In 1994, I received a B.S. degree in Plant Genetics and Molecular Sciences at the University of Bordeaux (France). One year later, I received a M.S. degree in Integrative Biology at the University of Nancy I (France). In 2004, I successfully defended my Ph.D in Plant Molecular Biology in the Food Sciences Department at the University of Bordeaux 1 (France). My Ph.D research focused on the functional validation of two regulatory proteins (MYB transcription factor) involved in the regulation of polyphenols' accumulation during grape berry development. Later this year, I joined Dr. Cushman laboratory at the University of Reno to study drought tolerance in grapevine using Affymetrix Microarrays. Two years later, still in Reno, I joined Dr. Cramer laboratory to study the molecular mechanisms responsible for the entry of grapevine buds into endodormancy. In 2009, I was offered a position of Assistant professor in the Department of Horticulture at Oregon State University. Meanwhile, I became a core member of the Oregon Wine Research Institute wherein I initially developed a research program on different aspects of wine grape performance for improved grape and wine production in Oregon. Since then, I have extended my research interests to other aspects of plant development and tolerance to biotic and abiotic stress using other plant models such as strawberry and Brachypodium Distachyon: a plant model system for cereal crop. Functional genomics including genetic engineering, plant pathogen-interactions plant physiology, and bioinformatics are the main tools used to address the different scientific questions.
Current members of the lab
Satayanarayana Gouthu (Ph.D): Satyanarayana is a Senior Research Associate from India. Before going the lab, he was Post-Doctoral Scientist in Dr. Cushman Lab at the University of Reno, Nevada where he studied the protein interactomes in Arabidopsis Thaliana under stress conditions. In 2010, he developed a research project focused on the regulation of ripening in grape berry with a particular focus on the contribution of seed to the ripening process. He is also part of the persons in charge of the development of a new genetic platform in grapevine functional genomic using the microvine model in collaboration with Dr. Mark Thomas. He is also coordinating a current project funded by the Oregon Wine Board and the Erath Family Foundation which the main research objective is to validate the function of a regulatory protein involved in the auxin signaling, Auxin Response Factor 4. This protein is suspected to control the timing of ripening initiation. The use of the CRISPR genome editing technology is explored to functionally characterize genes that are associated with traits of interest in grapevine production.
Landry Rossdeutsch (PhD): Landry joined the lab in September 2016 as Post-Doctoral student to develop a new research project for the lab focused on understanding the physiology of rootstock-scion interactions of grapevines. This project is a collaborative work between three researchers who are members of the Oregon Wine Research Institute (Drs. Paul Schreiner, Patty Skinkis, and Laurent Deluc). In 2015, he defended his Ph.D at the University of Bordeaux where he studied the physical and chemical mechanisms responsible for the regulation of stomatal closure under water deficit conditions. He mainly explored long-distance signaling mediated by roots by studying plant hormone and hydraulic signals on grapevines with different rootstock-scion combinations. At OSU, he is currently developing a multifaceted project with short and long-term objectives. The short-term objectives will provide vine physiology and applied viticulture researchers with a better understanding of how vine vigor and nitrogen affects root/shoot coordinated growth. The long-term goal is to define which physiological and molecular mechanisms result in different growth patterns depending on the rootstock/scion combinations.
Karly Vial: Karly is a sophomore student studying Biochemistry and Molecular Biology in the Honors College at OSU.
Sean Ryan Murphy: Karly is a sophomore student studying Biochemistry and Molecular Biology in the Honors College at OSU.
Victor Puoci: Victor is a sophomore student studying Biochemistry and Molecular Biology in the Honors College at OSU, with a minor in Music Performance. He is from Bothell, WA and is grateful for having grown up surrounded by many opportunities for involvement science, technology, and music. Victor is working with Satyanarayana Gouthu on the ARF4 project and more specifically on the Yeast Two Hybrid and strawberry components of the projects.
Tarah Gustafson: Tarah is a sophomore studying Biochemistry and Molecular Biology in the Honors College at OSU, with a minor in Chemistry. She is from Albany, OR. Tarah is working on a project related to Brachypodium Distachyon. The main goal of her research project is to look at how drought and nutrient deficiency (Nitrogen and Phosphorus) have an impact on the expression of genes associated with the synthesis and signaling of strigolactone, a plant hormone responsible for root shoot and root branching. She is using Brachypodium Distachyon as plant model (tillering, root growth, nutrient uptake).
Former Members of the lab
Joseph Schmidt (MSc): Joseph Schmidt was raised in Texas where he attended high school. In 2015, he graduated at Oregon State University with a B.S. in Horticulture, Plant Breeding & Genetics at Oregon State University. From 2015 to 2017, he went to graduate school and received a Msc in Horticulture. In the lab, he was in charge of a research project aimed to measure the accumulation dynamics of several classes of phytohormones during grape berry development, and the effects of two viticulture practices thereon. In 2018, he started his professional career as a Biological Research Technician, working for Dr. Alex Levin (SOREC) in collaboration with Deluc lab. The focus of his current work is in identifying the effects of Grape Red-Blotch-assiciated Virus (GRBaV) and irrigation on the metabolite profile of Pinot noir berries.
Mandy Driskill: Mandie Driskill is from Springfield, Oregon. She just graduated in horticulture with an emphasis in plant breeding and genetics. Within plant breeding and genetics, her special interests are in small fruits and berries. Driskill is also minoring in business with an emphasis in entrepreneurship. Driskill’s studies have led her to two great work experiences at Oregon State University. She works as an assistant to the head breeder in the Aroma Hops Breeding Program. She is also working on grapevine genotyping in the lab. . Her passion for genetics and berries stems from her four young children. After her graduation she immediately the master in Bioinformatics at the University of Oregon.
Grace Chang: Grace just graduated at Oregon State University. She is from Clackamas, the suburbs of Portland, and she has lived there for the past 14 years. She is studying BioHealth Sciences with the option of Laboratory Sciences and a minor in Chemistry. She hopes to enter in the field of forensics in the future! She is working on the Yeast Two Hybrids project with Satyanarayana.
Joey Orton: Joey Orton is from Dallas, OR, he is a Senior in Biology with an option in genetics and a minor in chemistry. Joey assets Landry in his research project aimed to study the impact of rootstock-scion interactions on Nitrogen assimilation and uptake in relation to the shoot growth in grapevine. Joeys true passion is herpetology and hopes to pursue a doctorate degree in evolutionary ecology.
Amanda Vondras (September 2011-August 2017): Amanda graduated (BSc) from Cornell University in Spring 2011. She joined the PhD Molecular and Cellular Biology Program in Fall 2011. In the lab, Amanda studied different aspects of fruit ripening including plant physiology, metabolomics and transcriptomics. Amanda defended her PhD in August 2017. She is currently working as Post-Doctoral Student in Dario Cantu lab at UC Davis.
