Carbon Oxysulfide Inhibition of the CO(2)-Concentrating Process of Unicellular Green Algae.

abstract：:The growth of transgenic tomato (Lycopersicon esculentum) plants that express in their apoplast yeast invertase under the control of the cauliflower mosaic virus 35S promoter is severely inhibited. The higher the level of invertase, the greater the inhibition of growth. A second phenotypic characteristic of these tran...
