Fractionation of Carbon Isotopes during Biogenesis of Atmospheric Isoprene.

abstract：:Removing the pods from soybean (Glycine max [L.] Merr. cv Wye) plants induces a change in leaf function which is characterized by a change in the leaf soluble protein pattern. The synthesis of at least four polypeptides ( approximately 27, 29, 54, and 80 kilodaltons) is enhanced, and these polypeptides accumulate to l...
