Know Your Roots: Introduction to Root Phenotyping for Plant Pathologists
Tuesday, October 20, 2020
12:00 - 2:30 p.m. Central Time
On Demand Coming Soon!
Many plant pathogens and beneficial microbes cause changes in root structure, whether from direct tissue loss, growth restriction, or repatterning caused by microbe-induced hormonal changes. By quantifying these effects, pathologists can reveal ways in which biotic interactions affect belowground plant health. This workshop is aimed at providing a broadly accessible, hands-on introduction to quantitative measurement of root traits. The workshop will be led by Dr. Larry York of the Noble Research Institute with contributions from several domain experts.
The benefits and drawbacks of platforms for root phenotyping in the context of plant disease will be discussed in this workshop, such as field shovelomics, rhizoboxes, rhizoslide methods, as well as options for imaging such as cameras or flatbed scanners. Attendees will watch recorded and live demonstrations on how to sample, prepare, and image roots using the RhizoVision Crown imager and flatbed scanners. Attendees will receive live instruction on how to use the free and open-source
RhizoVision Explorer software to quantify root length, diameter, and many other traits from root images. Participants will have ample opportunity to ask questions about their own root systems and root images. Links to the free software and practice image sets will be provided after registration. At the end of the workshop, participants will have the basic knowledge to include elements of root research in their own work.
Important Note: Rhizovision Explorer is a freeware program developed for use in Windows 10 with 64-bit processors; its publication and public release are in preparation. It works in Windows 8, but has not been developed or tested in other operating systems or in virtual Windows environments.
