Increased steady state mRNA levels of the STM and KNAT1 homeobox genes in cytokinin overproducing Arabidopsis thaliana indicate a role for cytokinins in the shoot apical meristem
Open accessAbstract
Summary: This study investigates the consequences of endo‐ genously enhanced biosynthesis of the plant hormone cytokinin in Arabidopsis thaliana (L.) Heynh. Tran‐ scriptional control of the bacterial ipt gene by the Drosophila melanogaster hsp70 promoter enabled temperature‐dependent increased cytokinin production in transgenic plants. Heat‐treated plants accumulated higher levels of unbound and bound zeatin‐type cyto‐ kinins, the latter being preferentially N‐conjugated glucosides. Cytokinin overproduction significantly increased the biomass of seedlings. Ipt transgenics had higher steady state mRNA levels of the shoot meristem specifying homeobox genes KNAT1 and STM, similar to the cytokinin‐overproducing shoot meristem mutant amp1 (hpt, cop2, pt) This finding, together with previously described phenotypic similarities between transgenic cytokinin‐overproducing plants and plants overexpressing the KNAT1 or KN1 genes, suggests that these factors act on the same pathway. We hypothesize that cytokinins act upstream of KNAT1 and STM. The influence of cytokinins on homeobox genes provides a link between the hormone and the developmental genes and indicates a role for cytokinins in the shoot apical meristem.

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.
