This is the fifth symposium report on Acetabularia biology since 1970. The 

 Round Table took place in Moscow in August 1978. Its outstanding feature was 

 the very high Russian attendance (two-thirds of all participants and con- 

 tributors) . The title of the book is somewhat surprising since only about a 

 third of the 31 papers deal directly with morphogenesis. Almost all papers 

 are short research reports, some of which were extensively edited. No dis- 

 cussions are recorded. 



Almost all papers of direct interest to our readers are to be found in 

 parts I and III. The only papers on electrophysiology in relation to morpho- 

 genesis are two by the group of Rogatykh and Zubarev in Moscow. According to 

 these, the action potentials would affect mRNA synthesis in the nucleus. 

 Other papers deal with morphogenetic substances, protoplasmic streaming and 

 polarised RNA transport. 



The papers are reproduced from typescripts. The volume is well produced 

 and has a host of beautiful photographic illustrations.

T.KUDREV, I.IVANOVA and E.KARANOV, eds. 1977. PLANT GROWTH REGULATORS 



Publ. House Bulg. Acad, of Sciences, Sofia. 769 pp., 276 figs., 184 tabs. 



This symposium took place in October 1975 in Sofia, Bulgaria. Of the 129 

 papers more than two thirds have authors from Eastern Europe, including the 

 DDR, with Bulgaria well represented. The remaining papers come from a vari- 

 ety of countries in other parts of the world. Apart from a longish review 

 by Chailakhyan on hormonal regulation of plant ontogenesis in species with 

 different photoperiodicities, all papers are very brief to short research 

 reports. 



The papers cover an enormous variety of subjects and species. There are 

 eight papers on auxins, nine on gibberellins ten on cytokinins, abscisic 

 acid and phenolic compounds, and seven on interactions among endogenous 

 growth regulators. A large section on synthetic growth regulators (75 pa- 

 pers) is subdivided into seven subsections , including one on nucleic acids, 

 enzymes and amino acid synthesis, (16 papers), one on relations with endo- 

 genous hormones (4), and one on the regulation of flowering (10). Finally, 

 there are 18 papers on general problems of growth regulation and on miscel- 

 laneous subjects. 



The book is produced from typescripts on rather poor-quality paper. It is 

 illustrated with numerous graphs and a few line drawings and photographs. 

 There is no index.
