Senescence: action of auxin and kinetin in control of RNA and protein synthesis in subcellular fractions of bean endocarp.

abstract：:Phloem protein 2 (PP2) is one of the most abundant and enigmatic proteins in the phloem sap. Although thought to be associated with structural P-protein, PP2 is translocated in the assimilate stream where its lectin activity or RNA-binding properties can exert effects over long distances. Analyzing the diversity of th...
