42. THE ROLE OF CHROMOSOMES IN DEVELOPMENT

The 23rd Growth Symposium was held in Amherst, Mass. in June 1964. All 

 participants except two came from the U.S.A. 



Most of the contributions are concerned with chromosome structure and 

 biochemistry, and with the regulation of gene function in a variety of organ- 

 isms. The relevance of these topics for development and differentiation is 

 obvious, and is once more stressed by Markert in his summary of the sympo- 

 sium which opens the book. However, the book as a whole is perhaps of more 

 immediate interest to geneticists and molecular biologists than to embryologists 

 in the strict sense. Therefore, only two contributions will be specifically men- 

 tioned, viz. that on genetic and functional mosaicism is the mouse (Russell), 

 and that on genetic control and regulation of developmental pathways (Lewis). 

 The latter paper is more specifically concerned with the fascinating bithorax 

 pseudoallelic series of mutants in Drosophila. 



The discussions held at the symposium are not recorded. The book is 

 adequately illustrated and has author and subject indexes.

43. MECHANISMS OF CELLULAR DIFFERENTATION AND 



INDUCTION 

 1963 



Editors: G. V. Lopashov. A. A. Nejfakh Izdatclstwo Nauka

This book, written in Russian, constitutes the report of a Symposium held in 

 Moscow in November 1963, and dealing with a variety of subjects in experi- 

 mental and molecular embryology. 



Since much very recent Russian literature is discussed in the various 

 contributions, it is expected that several non-Russian workers may wish to 

 read one or more contributions or to have them translated for their personal 

 use. Therefore, the entire table of contents is printed below. 



Most papers range in size between 10 and 20 pages, including the brief 

 discussions which follow most of the papers. Each paper has its own biblio- 

 graphy. The book is illustrated mostly with graphs and photomicrographs. 



Contents: Khesin: "Factors determining the synthesis of specific messenger RNA"; Spirin, 

 Belitsina and Ajtkhozhin: "Messenger RNA in early embryogenesis"; Nejfakh: "Use of 

 inhibition of nuclear exchange for research on the morphogenetic function of the nucleus in
