Comparative theoretical study of CO activation on clean and potassium-preadsorbed low index surfaces of transition metals.

Context: The efficient catalysis of CO adsorption and activation presents a formidable challenge due to its pronounced thermodynamic stability and kinetic inertia. Previous experiments have left gaps in understanding the promotional effects and underlying mechanism of potassium. In this study, we systematically investigate CO adsorption and activation on clean and potassium-preadsorbed low index surfaces of transition metals.

Ectopic expression of SsPETE2, a plastocyanin from Suaeda salsa, improves plant tolerance to oxidative stress.

Accumulating evidence indicates that plant plastocyanin is involved in copper homeostasis, yet the physiological relevance remains elusive. In this study, we found that a plastocyanin gene (SsPETE2) from euhalophyte Suaeda salsa possessed a novel antioxidant function, which was associated with the copper-chelating activity of SsPETE2. In S.

[Cloning and functional analysis of chitinase gene GbCHI from sea-island cotton (Gossypium barbadense)].

Chitinase is one of the important pathogenesis-related (PR) proteins in plants. By comparative proteomics study, a novel pathogen-responsive chitinase (known as GbCHI) has been identified from sea-island cotton (Gossypium barbadense). The GbCHI cDNA was cloned from wilt-resistant sea-island cotton and the anti-fungal activity of the gene product was investigated.

Central nervous system regulation of food intake and energy expenditure: role of galanin-mediated feeding behavior.

Galanin is a neuropeptide widely expressed in the brain. It is implicated in energy expenditure, feeding, and the regulation of body weight. Numerous studies have revealed that galanin regulates food intake via galanin receptors, 5-HT(1A) receptor and adrenergic α-2 receptor.

Proteomic analysis of the sea-island cotton roots infected by wilt pathogen Verticillium dahliae.

Verticillium wilt of cotton is a vascular disease mainly caused by the soil-born filamentous fungus Verticillium dahliae. To study the mechanisms associated with defense responses in wilt-resistant sea-island cotton (Gossypium barbadense) upon V. dahliae infection, a comparative proteomic analysis between infected and mock-inoculated roots of G.
