A new auxin homeostasis gene in Arabidopsis called SUR2 has been identified. This gene, mapped to the bottom of chromosome 4, is defined by two recessive nuclear mutants designated superroot2 (sur2), which display several abnormalities reminiscent of auxin effects. A number of these characteristics are similar to the phenotype of the previously described(More)
The production, isolation, and purification of specific chicken immunoglobulins (Igs) against three main groups of naturally occurring cytokinins are reported. The specific Igs directed against, respectively, zeatin riboside, dihydrozeatin riboside, and isopentenyladenosine are extracted from the egg yolk and used in radioimmunoassays that allow the(More)
The promoter activity of a 2.2-kb DNA fragment from the 5′ flanking sequence of the tap1 gene of snapdragon has been characterised in tobacco with the β-glucuronidase reporter gene. The tap1 promoter conferred to the reporter gene an expression that was limited to the early stages of anther development. Expression of the rolB gene of Agrobacterium(More)
Environmental stress affects plant growth and development. Several plant hormones, such as salicylic acid, abscisic acid, jasmonic acid and ethylene play a crucial role in altering plant morphology in response to stress. Developmental regulation often has the cell cycle machinery among its targets. We analyzed the effect of jasmonic acid (JA) and abscisic(More)
Localization of target cells forAgrobacterium-mediated transformation in the carrot root disc model has been achieved after inoculation with a disarmedA. tumefaciens strain harbouring a GUS-intron construct. The first GUS positive cells could be detected on both sides of the discs 48 h after inoculation. The transformed cells were always more numerous on(More)
Understanding the complete picture of ¯oral transition is still impaired by the fact that physiological studies mainly concern plant species whose genetics is poorly known, and vice versa. Arabidopsis thaliana has been successfully used to unravel signalling pathways by genetic and molecular approaches, but analyses are still required to determine the(More)

It has been proposed that the “eukaryotic” T-DNA-encoded indole-3-acetic acid (IAA) biosynthesis genes of Agrobacterium tumefaciens and their prokaryotic counterpart in Pseudomonas savastanoi originated from common ancestor genes. This paper provides additional evidence for the functional similarity between the gene products. We have demonstrated that a(More)
UNLABELLED pProRep is a web application integrating electrophoretic and mass spectral data from proteome analyses into a relational database. The graphical web-interface allows users to upload, analyse and share experimental proteome data. It offers researchers the possibility to query all previously analysed datasets and can visualize selected features,(More)
Effects of gibberellic acid and kinetic on α-amylase production during the germination of barley. - The action of gibberellic acid and kinetin, alone or combined at different concentrations, has been studied on α-amylase production in whole barley seedlings and in embryoless endosperms in course of the six first days of development in the dark. The classic(More)

The recent discovery showed that inositol phospholipids play essential role in cellular perception and transduction ofextracellular signals. It was presumed also that phosphatidylinositol system takes part in plant environment interaction, but there are no data about the phosphatidylinositol cycle participation in the transduction of temperature signal in(More)
