Abstract

CS-20-5 - Uncovering the genetic basis for natural variation of root system dynamics in Arabdidopsis

Monday, July 16
4:38 PM - 4:58 PM

As the interface between the soil environment and the rest of the plant, root systems play a key role in determining plant growth. The distribution of roots, termed root system architecture (RSA), is influenced by the surrounding environment. GLO-Roots (Growth and Luminescence Observatory for Roots) is a new soil-based root imaging technology, which enables detailed observations of Arabidopsis thaliana root system growth in soil. Using this system, we are developing methods to analyze complex RSA over time. Our goal is to characterize how the root systems of a diverse population of Arabidopsis accessions grow and will perform a genome wide association study to identify common alleles involved in RSA control. this work will investigate how plant root systems are distributed spatially within the soil and ultimately be combined with modelling approaches to identify ways plants regulate root system growth

Therese LaRue is a PhD candidate studying plant biology at Stanford. Her research focuses on understanding the spatial arrangement of plant root systems in soil using a new imaging technology called GLO-roots, which involves luminescent roots! Even when not in the lab, she spends her time taking care of plants and gardening.
