Leaves are specialized organs characterized by defined developmental destiny and determinate growth. The overexpression of Knotted1-like homeobox genes in different species has been shown to alter leaf shape and development, but a definite role for this class of genes remains to be established. Transgenics that overexpress Knotted1-like genes present some traits that are characteristic of altered cytokinin physiology. Here we show that lettuce (Lactuca sativa) leaves that overexpress KNAT1, an…

Cytokinin-Deficient Transgenic Arabidopsis Plants Show Multiple Developmental Alterations Indicating Opposite Functions of Cytokinins in the Regulation of Shoot and Root Meristem Activity Article, publication date, and citation information can be found at www.plantcell.org/cgi/doi/10.1105/tpc.014928
TLDR
The results are consistent with the hypothesis that cytokinins have central, but opposite, regulatory functions in root and shoot meristems and indicate that a fine-tuned control of catabolism plays an important role in ensuring the proper regulation of cytokinin functions.
The role of knox genes in plant development.
TLDR
In plants with simple leaves, knox genes are expressed exclusively in the meristem and stem, but in dissected leaves, they are also expressed in leaf primordia, suggesting that they may play a role in the diversity of leaf form.
Ectopic Expression of KNOTTED1-Like Homeobox Protein Induces Expression of Cytokinin Biosynthesis Genes in Rice1[W]
TLDR
It is concluded that KNOX protein simultaneously decreases GA biosynthesis and increases de novo CK biosynthesis through the induction of OsIPT2 andOsIPT3 expression, and the resulting high-CK and low-GA condition is required for formation and maintenance of the meristem.
Requirement of KNAT1/BP for the Development of Abscission Zones in Arabidopsis thaliana
TLDR
The characterization of an Arabidopsis T-DNA insertion mutant that shares considerable phenotypic similarity to the previously identified mutant brevipedicle (bp) is reported.
Cytokinin-induced expression of OSH1 in a shoot-regenerating rice callus.
TLDR
Results suggest that these cytokinin-signalling genes are positive regulators of the expression of OSH1, and mediate the OSH expression upon shoot regeneration from callus in rice.
Modulation of the Hormone Setting by Rhodococcus fascians Results in Ectopic KNOX Activation in Arabidopsis1[W][OA]
TLDR
Through transcript profiling, it is demonstrated that class-I KNOx genes are transcribed in symptomatic leaves and positioned the KNOX genes downstream in the signaling cascade triggered by R. fascians infection.
Ectopic expression of class 1 KNOX genes induce adventitious shoot regeneration and alter growth and development of tobacco (Nicotiana tabacum L) and European plum (Prunus domestica L)
TLDR
The induction of high-frequency regeneration of adventitious shoots in vitro from leaves and stem internodal sections of plum through the ectopic expression of a KNOX1 gene is the first such report for a woody perennial fruit trees.

Overexpression of the maize homeo box gene, KNOTTED-1, causes a switch from determinate to indeterminate cell fates.
TLDR
It is proposed that the KN1 homeo box gene plays a role in determining cell fate in maize and tobacco, and the consequences of KN1 overexpression appear to depend on the concentration ofKN1 and the timing of its expression during organogenesis.
Ectopic expression of maize knotted1 results in the cytokinin-autotrophic growth of cultured tobacco tissues
TLDR
The results suggest that the cytokinin-autotrophic growth of Kn1 lines could result from elevated steady-state levels of cytokinins, which are at least 10-fold higher than that of wild-type tobacco tissues and in the range reported for other cytokinIn-Autotrophic tobacco tissues.
A dominant mutation in the maize homeobox gene, Knotted-1, causes its ectopic expression in leaf cells with altered fates.
TLDR
Kn1 functions in its wild-type context as a regulator of cell determination and apparently alters the fates of leaf cells in which it is ectopically expressed from an early stage of leaf development.
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.
TLDR
The influence of cytokinin on homeobox genes provides a link between the hormone and the developmental genes and indicates a role for cytokinins in the shoot apical meristem.
Conditional transgenic expression of the ipt gene indicates a function for cytokinins in paracrine signaling in whole tobacco plants.
TLDR
The role of cytokinins as a long-range root-to-shoot signal in correlative control of apical dominance and sequential leaf senescence of tobacco is questioned, and the assumption that this hormone is relevant to paracrine signaling is supported.
KNAT1 induces lobed leaves with ectopic meristems when overexpressed in Arabidopsis.
TLDR
It is shown that ectopic expression of KNAT1 in Arabidopsis transforms simple leaves into lobed leaves, and further suggest that kn1-related genes may have played a role in the evolution of leaf diversity.
Controlled cytokinin production in transgenic tobacco using a copper-inducible promoter
TLDR
It is confirmed that endogenous cytokinin concentrations in tobacco transformants can be temporally and spatially controlled by the induction of ipt gene expression through the Cu-controllable gene-expression system.
Promoter tagging with a promoterless ipt gene leads to cytokinin-induced phenotypic variability in transgenic tobacco plants:implications of gene dosage effects.
TLDR
The results show that stably inherited developmental alterations due to a general or localized cytokinin overproduction can be obtained by the promoter-tagging approach.
A knotted1-like homeobox gene in Arabidopsis is expressed in the vegetative meristem and dramatically alters leaf morphology when overexpressed in transgenic plants.
TLDR
The hypothesis that class 1 kn1-like genes play a role in morphogenesis is supported by the characterization of two genes, KNAT1 and KNAT2 that were cloned from Arabidopsis using the kn1 homeobox as a heterologous probe.
Leaf Senescence Is Delayed in Tobacco Plants Expressing the Maize Homeobox Gene knotted1 under the Control of a Senescence-Activated Promoter
TLDR
The experiments extend the current understanding of kn1 function and suggest that in addition to mediating meristem maintenance, kn1 is capable of regulating the onset of senescence in leaves.
