This book tells briefly the story of the development and changes of the Brazilian agriculture. The early 1970s traditional agriculture, whose growth mostly occurred on the extensive margin, was progressively transformed during the following decades into a modern and highly competitive agriculture based on science and anchored on productivity gains. Table de contents: 1- The development of Brazilian agriculture, future tecnological challenges and opportunities; 2-Productivity and structural transformation in Brazilian agriculture:analysis of agricultural census data; 3- Agricultural policy in Brazil: subsidies and investments; 4- Technological trajectory and learning in the agricultural sector; 5- Embrapa: a sucess story of institutional innovation. |

Background: Sugarcane (Saccharum spp.) covers vast areas of land (around 25 million ha worldwide), and its processing is already linked into infrastructure for producing bioethanol in many countries. This makes it an ideal candidate for improving composition of its residues (mostly cell walls), making them more suitable for cellulosic ethanol production. In this paper, we report an approach to improving saccharification of sugarcane straw by RNAi silencing of the recently discovered BAHD01 gene responsible for feruloylation of grass cell walls. Results: We identified six BAHD genes in the sugarcane genome (SacBAHDs) and generated five lines with substantially decreased SacBAHD01 expression. To find optimal conditions for determining saccharification of sugarcane straw, we tried multiple combinations of solvent and temperature pretreatment conditions, devising a predictive model for finding their effects on glucose release. Under optimal conditions, demonstrated by Organosolv pretreatment using 30% ethanol for 240 min, transgenic lines showed increases in saccharification efficiency of up to 24%. The three lines with improved saccharification efficiency had lower cell-wall ferulate content but unchanged monosaccharide and lignin compositions. Conclusions: The silencing of SacBAHD01 gene and subsequent decrease of cell-wall ferulate contents indicate a promising novel biotechnological approach for improving the suitability of sugarcane residues for cellulosic ethanol production. In addition, the Organosolv pretreatment of the genetically modified biomass and the optimal conditions for the enzymatic hydrolysis presented here might be incorporated in the sugarcane industry for bioethanol production.
