The arabidopsis ATHB-8 HD-zip protein acts as a differentiation-promoting transcription factor of the vascular meristems.
ATHB-8, -9, -14, -15, and IFL1/REV are members of a small homeodomain-leucine zipper family whose genes are characterized by expression in the vascular tissue. ATHB-8, a gene positively regulated by… Expand

Cadmium-inducible expression of the ABC-type transporter AtABCC3 increases phytochelatin-mediated cadmium tolerance in Arabidopsis
Highlight AtABCC3 detoxifies cadmium by transporting phytochelatin–cadmium complexes into the vacuoles, and it can functionally complement abcc1 abcc2 mutants.

Functional Characterization of OsMADS18, a Member of the AP1/SQUA Subfamily of MADS Box Genes1[w]
MADS box transcription factors controlling flower development have been isolated and studied in a wide variety of organisms. These studies have shown that homologous MADS box genes from different… Expand

Modulation of intracellular proline levels affects flowering time and inflorescence architecture in Arabidopsis
We reported previously that the plant oncogene rolD anticipates and stimulates flowering in Nicotiana tabacum, and encodes ornithine cyclodeaminase, an enzyme catalysing the conversion of ornithine… Expand

The proline biosynthetic genes P5CS1 and P5CS2 play overlapping roles in Arabidopsis flower transition but not in embryo development.
Overexpression of the proline biosynthetic gene P5CS1 results in early flowering in Arabidopsis. However, the p5cs1 loss-of-function mutant exhibits a modest delay in flowering, suggesting that… Expand

Methyl jasmonate upregulates biosynthetic gene expression, oxidation and conjugation of polyamines, and inhibits shoot formation in tobacco thin layers.
The effect of methyl jasmonate (MJ) on de novo shoot formation and polyamine metabolism was investigated in thin layer explants of tobacco (Nicotiana tabacum L. cv. Samsun). A relatively low… Expand

Auxin Regulates Arabidopsis Anther Dehiscence, Pollen Maturation, and Filament Elongation[W]
We provide evidence on the localization, synthesis, transport, and effects of auxin on the processes occurring late in Arabidopsis thaliana stamen development: anther dehiscence, pollen maturation,… Expand

Development of the vascular system in the inflorescence stem of Arabidopsis
Summary • The development of the vasculature in the inflorescence stem and pedicel of two common Arabidopsis thaliana ecotypes is reported, describing the tissues and events in primary and secondary… Expand

Cadmium tolerance and phytochelatin content of Arabidopsis seedlings over-expressing the phytochelatin synthase gene AtPCS1
Previous studies demonstrated that expression of the Arabidopsis phytochelatin (PC) biosynthetic gene AtPCS1 in Nicotiana tabacum plants increases the Cd tolerance in the presence of exogenous… Expand

Auxin controls Arabidopsis anther dehiscence by regulating endothecium lignification and jasmonic acid biosynthesis.
It has been suggested that, in Arabidopsis, auxin controls the timing of anther dehiscence, possibly by preventing premature endothecium lignification. We show here that auxin content in anthers… Expand
