Changes in Leaf Proteins of Peas, Pisum sativum L., during Development on Deflorated Plants.

The soluble (sap) proteins of leaves of pea, Pisum sativum L. cvs. Alaska and Greenfeast, allowed to develop normally or deflowered, to prevent senescence, were separated by isoelectric focusing.There was a decline in certain proteins, with increases in others as the leaves aged but preventing senescence of the whole plant did not alter the pattern of change in leaf proteins. We concluded that whole plant senescence proceeds independently of leaf senescence.
