The Histidine Kinase Hik34 Is Involved in Thermotolerance by Regulating the Expression of Heat Shock Genes in Synechocystis1[w]
Histidine kinases (Hiks) in Synechocystis sp. PCC 6803 are involved in the transduction of signals associated with various kinds of environmental stress. To examine the potential role inExpand

Enhanced tolerance to light stress of transgenic Arabidopsis plants that express the codA gene for a bacterial choline oxidase
Arabidopsis thaliana was transformed with the codA gene from Arthrobacter globiformis. This gene encodes choline oxidase, an enzyme that converts choline to glycinebetaine. The photosyntheticExpand

Characterization of a two-component signal transduction system involved in the induction of alkaline phosphatase under phosphate-limiting conditions in Synechocystis sp. PCC 6803
The gene products of sll0337 and slr0081 in Synechocystis sp. PCC 6803 have been identified as the homologues of the Escherichia coli phosphate-sensing histidine kinase PhoR and response regulatorExpand

Activation of a plant gene by T-DNA tagging: auxin-independent growth in vitro.
A transferred DNA (T-DNA) tagging vector with the potential to produce dominant mutations was used with cocultured Agrobacterium tumefaciens and protoplasts to tag genes involved in the action of theExpand

bor1-1, an Arabidopsis thaliana Mutant That Requires a High Level of Boron
bor1–1 (high boron requiring), an Arabidopsis thaliana mutant that requires a high level of B, was isolated. When the B concentration in the medium was reduced to 3 [mu]M, the expansion of rosetteExpand

Transformation of Synechococcus with a gene for choline oxidase enhances tolerance to salt stress
Choline oxidase, isolated from the soil bacterium Arthrobacter globiformis, converts choline to glycinebetaine (N-trimethylglycine) without a requirement for any cofactors. The gene for this enzyme,Expand

Isolation of an Arabidopsis thaliana Mutant, mto1, That Overaccumulates Soluble Methionine (Temporal and Spatial Patterns of Soluble Methionine Accumulation)
We isolated Arabidopsis thaliana mutants that are resistant to ethionine, a toxic analog of methionine (Met). One of the mutants was analyzed further, and it accumulated 10- to 40-fold more solubleExpand

Enhanced germination under high-salt conditions of seeds of transgenicArabidopsis with a bacterial gene (codA) for choline oxidase
Arabidopsis thaliana was transformed previously with thecodA gene from the soil bacteriumArthrobacter globiformis. This gene encodes choline oxidase, the enzyme that converts choline toExpand

Factors controlling the efficiency of energy transfer from carotenoids to bacteriochlorophyll in purple photosynthetic bacteria
Abstract Efficiencies of energy transfer from carotenoids to bacteriochlorophyll in purple photosynthetic bacteria have been studied with chromatophores, isolated pigment-protein complexes, andExpand
