Three younger biochemists — T. 

 M. Laue, A. S. Klein, and A. P. Laudano 

 — are just getting their research under- 

 way. Laue, a physical biochemist, is 

 interested in the mechanism of blood 

 clotting, an extremely complex pro- 

 cess involving interactions among 

 molecules that has implications in 

 diseases such as hemophilia and heart 

 attacks. 



Like Green and Denis, Klein uti- 

 lizes genetic engineering methods in 

 her case to study genes which partici- 

 pate in the synthesis and regulation of 

 red and purple pigments found in or- 

 namental and sweet corn. Her research 

 includes the introduction of new genes 

 into corn, technology which may 

 eventually lead to ways of shortening 

 and improving the process of tradi- 

 tional plant breeding. 



Botany and Plant Pathology 



Specializations in this department — 



physiology, taxonomy, morphology, 

 phycology, ecology and pathology — 

 provide a diversity essential because 

 (1) new information is more likely to 

 be discovered by researchers who spe- 

 cialize and (2) most Station scientists 

 have teaching responsibilities, and, in 

 botany, courses such as taxonomy and 

 morphology are fundamental to an un- 

 dergraduate major. 



Biotechnology tools, including cell 

 and tissue culture, genetic transforma- 

 tion experiments and use of plant 

 growth regulators are basic to the re- 

 search of S. Minocha, plant physiolo- 

 gist and geneticist and current chair- 

 man of the department. Starting with 

 groups of cells in culture in the labora- 

 tory, he and his students are endeavor- 

 ing to grow whole plants such as lilac, 

 white pine, paper birch and poplar. 

 Plant growth hormones have been 

 studied for their role in the regulation 

 of lettuce seed germination. Greater 

 understanding of plant growth pro- 

 cesses should lead eventually to im-
