Motivation: improving yield has become essential for the sustainability of biofuel production
We need to develop tools for
sugarcane biotechnology
Goals
Identification of genes associated to sucrose, fiber quality and content and
drought tolerance
Evaluation of gene function through the generation and analysis of transgenic
sugarcane plants
Sugarcane gene promoter sequence and regulatory motif identification
Development of the SUCEST-FUN Database and computational tools
Need to understand the brazilian germplasm
and develop tools for the biotechnological route of sugarcane improvement
Approach: evaluate at the sequencing, expression and physiological level
50 cultivars 4 ancestor genotypes 8 progenies

S. spontaneum as an energy crop?
Plants X mass X % dry matter S .spontaneum 273 x 0,223kg x (100-63,1) = 2246,4 kg of total dry matter RB867515 73 x 1,563 x (100-83,7) = 1859,8 kg of total dry matter

Expression pattern analysis of ancestral species
- Few cell wall related genes were
differentially expressed
- S. spontaneum presented an up
regulation of catabolic pathways
(mainly carbohydrates) and down
regulation of anabolic pathways
- S. officinarum showed a down
regulation of carbohydrate
degradation genes; in leaf, few cell
wall genes were down regulated
(C3H, XTH, CesA, Csl)
- S. robustum showed a pattern
similar to S. spontaneum, presenting
an up regulation of carbohydrate
degradation (mainly starch) and
krebs Cycle.

2011/00818-8 - Development of alternative
biological models for the study of sugarcane
regulatory networks Dr. Carlos Hotta (coordinator) jun/11 –
ongoing
Aims:
1- To develop tools to use other biological models as
alternative to sugarcane
LUCIFERASE under a circadian promoter is a tool developed for Arabidopsis
that is being adapted to use in Brachypodium and sugarcane
2011/00818-8 Dr. Carlos Hotta jun/11 –
ongoing
Aims:
2- To associate the sugarcane circadian clock with its high
productivity and ability to accumulate sucrose >30% of the sense transcripts and > 20% of the antisense transcripts are
controlled by the circadian clock
Pathways like carbohydrate metabolism, photosynthesis, protein synthesis
and degradation, sugar and starch synthesis and degradation are controlled
by the circadian clock
Supressor of induced cell death by Bax protein and
negative regulator of cell death in plants, animals and

To understand the differential sucrose yield in Brazilian sugarcane
genotypes, using an integrate approach in which plant physiology,
morphology and anatomy are considered as the causes of variation in
sugarcane performance.
Basic question:
Why do some sugarcane genotypes accumulate more sucrose in stalks than others?
Derived questions:
Question #1- Do they have higher photosynthetic capacity and/or higher leaf area and/or
higher sucrose storage capacity and/or any difference in carbohydrate metabolism in
leaves or stalks?
Question #2- Does canopy architecture favor the plant metabolism, especially
photosynthesis? Does the high solar energy availability at the basal canopy positions
change the functional leaf area and then the plant photosynthesis and carbohydrate
production in sugarcane genotypes with contrasting canopy architecture and yield?
Question #3- Is the sugarcane genotype with high sucrose yield less affected by
environmental constraints during the winter season? How do sugarcane cultivars with
differential sucrose yield respond to cold and/or drought stress? Does this response
change during the plant cycle?

Question #3- Is the sugarcane genotype with high sucrose yield less affected by
environmental constraints during the winter season? How do sugarcane
cultivars with differential sucrose yield respond to cold and/or drought stress?
Does this response change during the plant cycle?
The cultivar with more photosynthesis had more stalk yield but was much more sensitive to drought
