"4. 1^ microorganisms are used to introduce vectors, the assessment 
of subsequent absence of the microorganisms should be specified. 
Indicate the means of strain identification and retrieval. 
"C. Characteristics and Monitoring of Plants. 
"1. Provide data frcm greenhouse and/or growth chamber studies under 
simulated field conditions to support prospective field studies. 
Data should include morphological data for at least two generations 
of plants. 
"Specify plant monitorina procedures; frequency; types of data to 
be obtained including leaf, seed, fruit, or root characteristics. 
"2. Provide data for field plot design on the following: 
"a. total area; 
"b. location: where, how many; 
"c. plot design: replication, row spacing, planting, border rcws, 
etc . ; 
"d. name cultivar(s), if appropriate; 
"e. specify plant monitoring procedures: frequency; 
types of data to be obtained including leaf, 
seed, fruit, or root characteristics; abnormalities, 
such as diseases; insect population monitoring; 
collection of meteorological data, etc; types of 
data to be sought, such as yield, resistance to 
stress, lodging, etc.; 
"f. specify monitoring of the vector and/or introduced DNA; and 
"g. specify access and security measures." 
Pr. Segal of the EPA said the working group should stress that similar lists should 
be developed for microorganisms and weeds. 
RISK ASSESSMENT WORKSHOP 
Dr. Tolin said the NTH and the USDA were intending to hold a risk assessment 
workshop in the fall of 1984 to address questions on deliberate release of 
organisms containing recombinant ENA molecules. Dr. Tolin hoped this workshop 
would deal with state of the art research. She asked the working group to identify 
individuals to serve on a steering ccmmittee.
