bus, a Bushy Arabidopsis CYP79F1 Knockout Mutant with Abolished Synthesis of Short-Chain Aliphatic Glucosinolates
Open accessAbstract
A new mutant of Arabidopsis designated bus1-1 (for bushy), which exhibited a bushy phenotype with crinkled leaves and retarded vascularization, was characterized. The phenotype was caused by an En-1 insertion in the gene CYP79F1. The deduced protein belongs to the cytochrome P450 superfamily. Because members of the CYP79 subfamily are believed to catalyze the oxidation of amino acids to aldoximes, the initial step in glucosinolate biosynthesis, we analyzed the level of glucosinolates in a CYP79F1 null mutant (bus1-1f) and in an overexpressing plant. Short-chain glucosinolates derived from methionine were completely lacking in the null mutant and showed increased levels in the overexpressing plant, indicating that CYP79F1 uses short-chain methionine derivatives as substrates. In addition, the concentrations of indole-3-ylmethyl-glucosinolate and the content of the auxin indole-3-acetic acid and its precursor indole-3-acetonitrile were increased in the bus1-1f mutant. Our results demonstrate for the first time that the formation of glucosinolates derived from methionine is mediated by CYP79F1 and that knocking out this cytochrome P450 has profound effects on plant growth and development.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
