Sugarcane refinery
CRISPR-CANE PPO and Drought
• The sugar refinement requires addition of chemicals, demands sophisticated physical structure,
requires high cost and results in the removal of >90% of their vitamins and minerals;
• CRISPR-CANE PPO is an promising strategy due to the reduction of costs of refinement and
maintenance of the nutritional characteristics of sugar;
• It can be applied to several commercial cultivars;
• Global expansion of the Brazilian sugar market;

Increase the thermotolerance
• By the introgression of genes or mutations associated to heat tolerance• Ex. Slick hair locus derived from cattle breeds like Senepol and Criollo
(Caribean Bos taurus) associated to an increased thermotolerance• short hair length
• Holstein cows with short hair - more tolerant to heat stress

Parasites
• Animals more resistant to parasites• Zebu cattle (Bos indicus) – more resistant to ticks• Search for target genes and mutations• Genomic selection and/or editing
• Control of insect population (ticks and flies)
• High infestation causes low productivity• Uses of insecticides – milk withholding period
• diseases transmission (babesiosis and anaplasmosis)
• CRISPR/Cas9 and gene drive

Increase the rumen digestibility• Low digestibility of tropical forages – due to high content of
hemi-cellulose and/or lignin
• Can not be digested by rumen microbiome - lack of enzymes
• Modification of rumen microbiome to express fibrolytics or ligninolytic enzymes:
• Xilanases (hemi-cellulose), laccases (lignin), etc
• Contributes to increase feed efficiency
Reduce methane emission
• Emission of non-CO2 greenhouses gases (e.g. methane)• 21% of non-CO2 emission is projected to be from livestock in 2030
