with other growth factors, and on their practical apphcations. Fourteen papers 

 are in German and four in Enghsh. Most of the German papers have Enghsh 

 summaries. Several of them are followed by brief discussions, usually in 

 German. 



The book is well produced and well illustrated. It has no indexes. 



53 PLANT STRUCTURE AND DEVELOPMENT 



A pictorial and physiological approach 

 1969 

 by T. P. O'Brien and M. E. McCully Collier-Macmillan Ltd. 



114 pp., 155 figs. London 



(paper-bound) SBN 02 388770 8 



Price: £ 5.0.0; $ 9.95 



Contents: 1. The cell; 2. Cell production: mitosis; 3. The root; 4. The shoot apex and leaf 

 initiation; 5. The leaf; 6. Buds; 7. The stem; 8. The reproductive tissues; 9. The seed. 



This book was written primarily for undergraduate students and is intended 

 as an introductory and selective guide to the internal structures of higher 

 plants and their functions. Most of the anatomy and histology is treated 

 pictorially, while the text concisely but authoritatively summarizes what is 

 known of the function of the structures illustrated as investigated by experi- 

 mental morphology, developmental biology, physiology, and biochemistry. The 

 book has a laudative preface by K. V. Thimann. 



Almost all illustrations are photographs of outstanding quality. They com- 

 prise macrographs, micrographs of freehand or very thin sections (stained with 

 various specific procedures), electron micrographs, and some phase contrast 

 and interference contrast photographs. All chapters have lists of general and 

 specific references (the latter are numerically referred to in the text). The 

 book is beautifully printed and has a short index. 



54 DIFFERENCIATION FONGIQUE 



1969 

 by G. Turian Masson et Cie 



Monographies de Physiologie Vegetale, vol. 5 Paris 



144 pp., 30 figs., 10 tbs., 2 pis. Price: F 50 



(paper-bound) 



This book is a first attempt to synthesize the large body of data at present 

 available on fungal differentiation and morphogenesis. The author has been 

 an active investigator in this field for nearly twenty years. 



Although primarily written for students, the book will certainly be useful 

 to others who wish to orient themselves in the field. The emphasis is on 

 modern research carried out with physiological, biochemical, and ultra- 

 structural techniques. The discussion is therefore intentionally restricted largely 

 to those forms which have proved most useful for this type of work (moulds 

 and yeasts ) . 



Apart from brief introductory and concluding chapters, the book is in three 

 main chapters successively discussing vegetative differentiation (29 pp.), sex- 

 ual differentiation (gametogenesis) (26 pp.), and spore differentiation (sporu- 

 lation) (45 pp.). In the first of these some attention is devoted to the cellular 

 slime molds. The true shme molds are discussed in connection with sporulation 

 in the third main chapter. 



The book is illustrated mostly with line drawings. The bibliography contains 

 about 600 titles, most of them recent, the most recent ones dating from 1967. 

 The book unfortunately has no indexes, which reduces its value as a reference 

 work. The price of the book seems excessive.
