of Plant Materials, " and began by asking whether item A-l was adequate. That 
item reads as follows : 
"'Tomato plants will be inoculated' is insufficient. Give common ard 
scientific names of plants and cultivars if appropriate." 
Dr. Scandalios said simply requiring the identity of "cultivars" would not com- 
pletely identify the genetic origin. Dr. Tolin said genetic origin can be 
described by the terms "line," "introduction," "seeds," "hybrid," etc. 
Dr. Vidaver said item A-l should require a description sufficient to permit the 
plant to be identified. Dr. Segal asked if the phrase "complete and common 
nomenclature" would be adequate. Dr. Tolin replied that more than complete 
nomenclature would be required to identify the genetic origin. Dr. Pirone 
suggested the phrase "cultivars and genetic lines" be used. Dr. Clowes sug- 
gested the words "identify by" be substituted for the word "give." 
Dr. Lacy asked if the second sentence of item A-l is necessary. Drs. Vidaver 
and Tolin replied that this sentence was included for historical reasons; the 
Plant Working Group had often found descriptions in proposals sutmitted for 
review rudimentary. Dr. Fedoroff felt this type of directive was unnecessary 
and could be deleted without affecting the informational content of the guidance 
document. Drs. Tolin and Vidaver agreed to delete the second sentence. 
Dr. McGarrity then called the working group's attention to item A-2 which reads 
as follows: 
"If appropriate, give data or information on the relative homogeneity of the 
plant cultivar, and specific genetic markers the cultivar is known to 
possess. " 
Dr. Arntzen felt item A-2 should request relevant data. Dr. Fedoroff felt item 
A-2 should be incorporated into item A-l. Dr. Scandalios said item A-2 requests 
different information than item A-l; for this reason, it may be preferrable 
to have two separate statements. Dr. Fedoroff suggested A-l and A-2 could be 
combined as follows: 
"Give common and scientific names of plants. Identify the specific cultivars 
or genetic lines to be used. Include information on the relative homogeneity 
of the plant cultivars or lines and specific genetic markers they are known 
to possess . " 
The working group agreed to accept Dr. Fedoroff 's proposed language. 
Dr. McGarrity then called the working group's attention to items B-l and B-2 of 
Section B, "Vectors ard Method of Introduction." Items B-l and B-2 read as 
follows: 
"1. Describe the cloned DNA segment and its expression in the new 
host.
