title: Developmental changes of sea urchin histones.
abstract: The changes of histones related to the development of sea urchin embryos from blastula to pluteus stage were studied by an electrophoretic method. The observed alterations were found to be quantitative ones and related to the transition of embryos from blastula to gastrula stage. During this period an increase in the relative amount of the F-1 and F-3 histones on account of the F2b + F2a2 was observed. The patterns of gastrula and pluteus histones were found to be similar.
