Due to its hydrophobic nature, sorgoleone\u2010358 can be strongly adsorbed onto soil organic matter, resulting in increased sorgoleone soil persistence. Because of the herbicidal activity of sorgoleone on many small\u2010seeded weeds, concerns have been raised that sorghum residues may have a detrimental effect on emergence of wheat used as a double crop in the southeastern United States. Laboratory experiments were conducted to evaluate root exudate production and its sorgoleone\u2010358 content for 36 cultivated sorghum cultivars as well as eight shattercane [<jats:italic>Sorghum bicolor<\/jats:italic> (L.) Moench ssp. <jats:italic>arundinaceum<\/jats:italic> (Desv.) de Wet &amp; Harlan] accessions and one johnsongrass [<jats:italic>S. halepense<\/jats:italic> (L.) Pers.] accession. Using a capillary growing mat system, root exudate was extracted with dichloromethane and subjected to chromatography analysis to determine sorgoleone\u2010358 content. Root biomass of 7\u2010 to 12\u2010d\u2010old seedlings averaged 18.8\u00a0mg g<jats:sup>\u22121<\/jats:sup> seed, and root exudate production ranged from 0.2 and 4.8\u00a0mg g<jats:sup>\u22121<\/jats:sup> root fresh weight (RFW). The amount of sorgoleone produced varied greatly among sorghum accessions. Sorgoleone\u2010358 amount in the root exudate averaged 0.5\u00a0mg g<jats:sup>\u22121<\/jats:sup> RFW and varied from 0.13 to 1.05\u00a0mg g<jats:sup>\u22121<\/jats:sup> for shattercane cultivar S7 and cultivated sorghum cultivar 992123, respectively. Regarding volume of root biomass, sorgoleone\u2010358 levels averaged 0.49\u00a0mg g<jats:sup>\u22121<\/jats:sup> (range, 0.06\u20131.46\u00a0mg g<jats:sup>\u22121<\/jats:sup>) for sorghum cultivar AAS3479 and shattercane cultivar S2, respectively. Segregation of commercial sorghum cultivars according to their maturity group did not show any difference in root biomass and dry extract production, but early\u2010maturing cultivars produced on average 18% less sorgoleone\u2010358 compared with medium\u2010 and late\u2010maturing cultivars. These results suggest that sorgoleone production may be genetically constitutive because sorghum growing conditions were identical across cultivars.<\/jats:p>","DOI":"10.1002\/jeq2.20038","type":"journal-article","created":{"date-parts":[[2020,3,4]],"date-time":"2020-03-04T04:00:50Z","timestamp":1583294450000},"page":"368-377","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Conservation and divergence in sorgoleone production of sorghum species"],"prefix":"10.1002","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0194-9675","authenticated-orcid":false,"given":"Thierry E.","family":"Besan\u00e7on","sequence":"first","affiliation":[{"name":"Dep. of Plant Biology Rutgers Univ.
