Brazil is the world’s leading sugar producer
and exporter:
- Sugar production: 38.2 million tons
- 25 % of global production
- 50 % of world exports
85%
In 2012/13, Brazilian ethanol production reached:
- 23.2 billion liters (6.1 billion gallons)
- Most of this production is absorbed by the
domestic market where it is sold as either pure
ethanol fuel or blended with gasoline

COMMUNICATION N° 07 - OCTOBER 21st, 2010
National Technical Commission on Biosafety (CTNBio) stipulates the following
conditions for genetically modified sugar cane disposal:
“The biomass produced by experiments with GM sugar cane should be discarded in
distilleries or crushed and buried in graves in areas with CQB”

Besides being exotic:
•
•
•
•
Pollen has low viability in normal conditions
Requires very specific conditions to flower
Sexual reproduction (Northeast Region of Brazil)
There no known wild relatives in Brazil
Recent studies:
some botanists have classified some Brazilian native
plants from Erianthus genus as belonging to the
Saccharum genus

SECTION IV- SUGGESTED CONSTITUENTS TO BE ANALYSED
RELATED TO FOOD USE
The key constituents suggested to be analysed in sugarcane
intended for human consumption are shown.
SECTION V - SUGGESTED CONSTITUENTS TO BE ANALYSED
RELATED TO FEED USE
The key constituents suggested to be analysed in sugarcane
intended for animal consumption are shown below. Acid
detergent fibre (ADF) and neutral detergent fibre (NDF) are
relevant analytes particularly for ruminant feed.

Compositional Analysis – Baseline Data
food
An important component of demonstrating that the products of
GM sugarcane varieties are substantially equivalent to
conventional varieties is whether the nutritional composition falls
within the range of compositions that are currently found in
production
The science-based regulatory assessment relies on good baseline
data on the biology of conventional varieties for comparison with
the new modified varieties to identify any potential changes.

Recommended Reference
GM Sugarcane Regulation in Brazil
Overview of Problems and Prospects
Sugarcane Additional Issues
-
Introduced trait is not easily transfered to other varieties by the breeding programs (around 10
years)
Cane growers need different varieties of sugarcane for different environmental conditions
New Events with same/similar constructs = shall pass through a Simplified Analysis by CTNBio.

CHAPTER I
PRELIMINARY AND GENERAL PROVISIONS
Article 3. GMOs containing the same genetic
construction used in a GMO of the same species, for
which a technical opinion favorable to commercial
release in Brazil has already been issued, shall be
subject to a simplified analysis for release thereof, at
the discretion of CTNBio.
Suggestions: all data from risk assessment of the
first variety approved should be used with the
inclusion of the following data:
1- Molecular characterization of the GMO related
to: (1) the number of copies inserted, and (2) the
location of insertion into the genome, where
possible, (3) flanking sequences, where possible;
2 – Compositional analysis;
3 - Determination of the expression level(s) of the
product of the gene inserted in the receptor
organism.
