Acid detergent fibre (ADF) and neutral detergent fibre (NDF) are relevant analytes particularly for ruminant feed. feed GM Sugarcane Regulation in Brazil Overview of Problems and Prospects 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. feed Dr. Giancarlo Conde Xavier de Oliveira (ESALQ/USP) Deadline: 2017/2018 Safety of GM sugarcane products Investigation of Residual DNAs and proteins in Sugar from Sugarcane Sugarcane Industrial Processing in a Mill Raw Juice WT GM Sugarcane Agro nptII GM Sugarcane biolistics nptII Leaf, Fibre, Juice, Syrup, Filter Mud, Molasses, Sugar The composition of sucrose, glucose and frutose in juice and raw sugar were indistinguishable Safety of GM sugarcane products Sugarcane Artisanal Processing Rapadura, Muscovado Sugar and Sugarcane Syrup DNA: + Protein: + DNA: + Protein: + 1 1 3 2 4 2 3 4 DNA: Protein: - DNA: Protein: - DNA: Protein: - DNA: Protein: - Cachaça Regulation of (GM) Sugarcane in Brazil 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. Normative Resolution n° 05 (CTNBio*) Requirements for the Commercial Release GMO and their byproducts *NATIONAL BIOSAFETY TECHNICAL COMMISSION 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.
