P. S. CARLSON, chairman. 1974. BASIC MECHANISMS IN PLANT MORPHOGENESIS 

 Brookhaven National Lab., Upton. Brookhaven Symposia in Biology No. 25. VII, 

 429 pp., 160 figs., 43 tabs. $ 10.60 (paper), $ 1.45 (microfiche) 



The analysis of plant morphogenesis at all levels from the organismal down to the 

 molecular-genetic has in recent years made considerable progress. This symposium pro- 

 vides a useful and interesting cross-section of these advances. Large sections of it will be 

 read with profit by general developmental biologists, particularly those preparing a lecture 

 course in developmental biology or genetics. 



There are two general lectures which are both extremely interesting to read for 

 zoologists: one by Sussex on the applicability of concepts of animal development to plant 

 systems, and a longer one by Stebbins on the "evolution ' of polarity and morphogenetic 

 patterns. The latter is particularly thought-provoking. The 21 more specialist papers are 

 arranged in five sections as follows: Morphogenesis in lower forms (4 papers); Factors 

 affecting morphogenesis (4); Cellular factors affecting morphogenesis (4), and two sec- 

 tions on The genetics of morphogenesis (together 9 papers). 



The papers are reproduced with minimal editing and therefore rather heterogeneous in 

 style; they are well illustrated.

This volume contains the papers read at an international symposium held in Nijmegen, 

 Netherlands in August, 1974. By reproducing the (unedited) papers from typescript very 

 rapid publication was achieved. Almost all of the 43 papers by authors of many 

 nationalities are brief reports or summaries of recent research. Together, they represent a
