Sulfhydryls in Plants. II. Distribution in Tissues.

Abstract

Amperiometric silver titration was employed for the estimation of the sulfhydryl contents of etiolated pea seedlings, oat coleoptiles, bean leaves, and sunflower intemodes. Preliminary estimates of the protein and non-protein sulfhydryl contents of sub-cellular fractions are also reported. The sulfhydryl:protein N ratios were fairly uniform among the fractions. The contents of sulfhydryls in the plant tissues tested compared closely with those reported for mammalian tissue on a fresh weight basis.
