      abstract     = {For the characterization of BOA-OH insensitive plants, we
                      studied the time-dependent effects of the
                      benzoxazolinone-4/5/6/7-OH isomers on maize roots. Exposure
                      of Zea mays seedlings to 0.5 mM BOA-OH elicits root
                      zone-specific reactions bythe formation of dark rings and
                      spots in the zone of lateral roots, high catalase activity
                      on root hairs, and no visible defensereaction at the root
                      tip. We studied BOA-6-OH- short-term effects on membrane
                      lipids and fatty acids in maize root tips incomparison to
                      the benzoxazinone-free species Abutilon theophrasti Medik.
                      Decreased contents of phosphatidylinositol inA. theophrasti
                      and phosphatidylcholine in maize were found after 10–30
                      min. In the youngest tissue, α-linoleic acid
                      (18:2),decreased considerably in both species and recovered
                      within one hr. Disturbances in membrane phospholipid
                      contents werebalanced in both species within 30–60 min.
                      Triacylglycerols (TAGs) were also affected, but levels of
                      maize diacylglycer-ols (DAGs) were almost unchanged,
                      suggesting a release of fatty acids for membrane lipid
                      regeneration from TAGs whileresulting DAGs are buildings
                      blocks for phospholipid reconstitution, concomitant with
                      BOA-6-OH glucosylation. Expres-sion of superoxide dismutase
                      (SOD2) and of ER-bound oleoyl desaturase (FAD2-2) genes were
                      contemporaneously upregulated in contrast to the catalase
                      CAT1, while CAT3 was arguably involved at a later stage of
                      the detoxification process.Immuno-responses were not
                      elicited in short-terms, since the expression of NPR1, POX12
                      were barely affected, PR4 after6 h with BOA-4/7-OH and PR1
                      after 24 h with BOA-5/6-OH. The rapid membrane recovery,
                      reactive oxygen species, andallelochemical detoxification
                      may be characteristic for BOA-OH insensitive plants.},
