We demonstrate the ability of a semiautomated 3D in vivo imaging and digital phenotyping pipeline to interrogate the quantitative genetic basis of root system growth in a rice biparental mapping population, Bala x Azucena. We phenotyped &gt;1,400 3D root models and &gt;57,000 2D images for a suite of 25 traits that quantified the distribution, shape, extent of exploration, and the intrinsic size of root networks at days 12, 14, and 16 of growth in a gellan gum medium. From these data we identified 89 quantitative trait loci, some of which correspond to those found previously in soil-grown plants, and provide evidence for genetic tradeoffs in root growth allocations, such as between the extent and thoroughness of exploration. We also developed a multivariate method for generating and mapping central root architecture phenotypes and used it to identify five major quantitative trait loci (r2 = 24-37%), two of which were not identified by our univariate analysis. Our imaging and analytical platform provides a means to identify genes with high potential for improving root traits and agronomic qualities of crops.","lang":"eng"}],"volume":110,"_id":"2822","oa":1,"scopus_import":1,"language":[{"iso":"eng"}],"publication":"PNAS","publication_status":"published","pmid":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"MaJö"},{"_id":"HeEd"}],"day":"30","publisher":"National Academy of Sciences","author":[{"first_name":"Christopher","last_name":"Topp","full_name":"Topp, Christopher"},{"full_name":"Iyer Pascuzzi, Anjali","first_name":"Anjali","last_name":"Iyer Pascuzzi"},{"first_name":"Jill","last_name":"Anderson","full_name":"Anderson, Jill"},{"last_name":"Lee","first_name":"Cheng","full_name":"Lee, Cheng"},{"full_name":"Zurek, Paul","first_name":"Paul","last_name":"Zurek"},{"id":"3C0C7BC6-F248-11E8-B48F-1D18A9856A87","full_name":"Symonova, Olga","last_name":"Symonova","first_name":"Olga"},{"first_name":"Ying","last_name":"Zheng","full_name":"Zheng, Ying"},{"full_name":"Bucksch, Alexander","first_name":"Alexander","last_name":"Bucksch"},{"last_name":"Mileyko","first_name":"Yuriy","full_name":"Mileyko, Yuriy"},{"last_name":"Galkovskyi","first_name":"Taras","full_name":"Galkovskyi, Taras"},{"full_name":"Moore, Brad","last_name":"Moore","first_name":"Brad"},{"full_name":"Harer, John","last_name":"Harer","first_name":"John"},{"last_name":"Edelsbrunner","first_name":"Herbert","orcid":"0000-0002-9823-6833","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","full_name":"Edelsbrunner, Herbert"},{"full_name":"Mitchell Olds, Thomas","last_name":"Mitchell Olds","first_name":"Thomas"},{"full_name":"Weitz, Joshua","last_name":"Weitz","first_name":"Joshua"},{"full_name":"Benfey, Philip","last_name":"Benfey","first_name":"Philip"}],"status":"public","external_id":{"pmid":["25673779"]},"publist_id":"3979","date_updated":"2021-01-12T06:59:58Z","oa_version":"Submitted Version","type":"journal_article","page":"E1695 - E1704","doi":"10.1073/pnas.1304354110","issue":"18","main_file_link":[{"url":"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4378147/","open_access":"1"}],"quality_controlled":"1","title":"3D phenotyping and quantitative trait locus mapping identify core regions of the rice genome controlling root architecture","date_published":"2013-04-30T00:00:00Z","citation":{"ieee":"C.
