Regulation of Sulfate Uptake and Expression of Sulfate Transporter Genes in Brassica oleracea as Affected by Atmospheric H2S and Pedospheric Sulfate Nutrition1
Demand-driven signaling will contribute to regulation of sulfur acquisition and distribution within the plant. To investigate the regulatory mechanisms pedospheric sulfate and atmospheric H2S supply… Expand
Atmospheric H2S as plant sulfur source: Interaction with pedospheric sulfur nutrition - a case study with Brassica oleracea L.
Elevated levels of hydrogen sulfide in the plant environment: nutrient or toxin
Hydrogen sulfide (H2S) is a malodorous gas with a typical “rotten egg” odor that can be smelt at levels of 0.02 μl l-1 and higher (for chemical and physical properties of H2S, see the review of… Expand

Exposure of Chinese cabbage (Brassica pekinensis) to enhanced Cu(2+) concentrations (1-10 microM) resulted in leaf chlorosis, a loss of photosynthetic capacity and lower biomass production at > or =… Expand
Impact of Atmospheric Sulfur Deposition on Sulfur Metabolism in Plants: H2S as Sulfur Source for Sulfur Deprived Brassica oleracea L.
Brassica oleracea L. was rather insensitive to atmospheric H2S: growth was only negatively affected at greater than or equal to 0.4 mu l l(-1). Shoots formed a sink for H2S and the uptake rate showed… Expand
FREEZING TOLERANCE AND BIOCHEMICAL-CHANGES IN WHEAT SHOOTS AS AFFECTED BY H2S FUMIGATION
Fumigation of winter wheat with H2S during low temperature acclimation substantially reduced the development of freezing tolerance of the leaves. After 6 weeks of low temperature exposure… Expand
Interaction between metabolism of atmospheric H2S in the shoot and sulfate uptake by the roots of curly kale (Brassica oleracea)
Exposure of curly kale (Brassica oleracea L.,) to gaseous H2S resulted in a decreased sulfate uptake by the roots. At 0.2 mu l l(-1) H2S, a level sufficient to meet the sulfur need of plants for… Expand
Copper toxicity in Chinese cabbage is not influenced by plant sulphur status, but affects sulphur metabolism-related gene expression and the suggested regulatory metabolites.

The toxicity of high copper (Cu) concentrations in the root environment of Chinese cabbage (Brassica pekinensis) was little influenced by the sulphur nutritional status of the plant. However, Cu… Expand
