The Macauba palm has been studied because of increasing global interest in multipurpose resilient plants, with no food or energy competition. The crop encompasses an opportunity to social inclusion, profitable activity and environmental care in Brazil. However, for its production to be competitive, it demands a deeper analysis of how the Agroindustrial System (AIS) is currently organized and what is needed to go forward. The objectives of the present study were to characterize and evaluate the competitiveness of macauba AIS at the main Brazilian production region, the north of Minas Gerais State. Stakeholders engaged in fruit picking and processing segments were identified and characterized. In addition, strategic actions to strengthen this AIS were proposed. The framework used to evaluate the competitiveness of the AIS includes data gathering from field interviews, direct observations and analysis of the macauba AIS. Some challenges were picked from the direct observations such as the reliance of production on unfavourable environmental conditions, the deficiencies in technical assistance and the difficulty of farmers to access credit and public policies. Despite those hurdles, the examined AIS showed potential to expand and become competitive, promoting better conditions for the permanence of family farmers/communities in the countryside. It is important to consider that macauba exploitation is getting to a point of transition from extractive activity to a systematized planting of the palm. Some strategies to boost this growth are better coordination among the agents acting in the AIS, establishment of more active R&D and technical assistance partnerships, capacity building/ training offerings, and provision of resources for investments intended for the sustainable development of the macauba AIS and market access.

Abstract: a-Amylases are common enzymes responsible for hydrolyzing starch. Insect-pests, whose larvae develop in seeds, rely obligatorily on a-amylase activity to digest starch, as their major food source. Considering the relevance of insect a-amylases and the natural a-amylase inhibitors present in seeds to protect from insect damage, we report here the molecular cloning and nucleotide sequence of the full-length AmyHha cDNA of the coffee berry borer, Hypothenemus hampei, a major insect-pest of coffee crops. The AmyHha sequence has 1879 bp, containing a 1458 bp open reading frame, which encodes a predicted protein with 485 amino acid residues, with a predicted molecular mass of 51.2 kDa. The deduced protein showed 55?79% identity to other insect a-amylases, including Anthonomus grandis, Ips typographus and Sitophilus oryzae a-amylases. In depth analysis revealed that the highly conserved three amino acid residues (Asp184, Glu220, and Asp285), which compose the catalytic site are also presented in AmyHha amylase. The AmyHha gene seems to be a single copy in the haploid genome and AmyHha transcription levels were found higher in L2 larvae and adult insects, both corresponding to major feeding phases. Modeling of the AmyHha predicted protein uncovered striking structural similarities to the Tenebrio molitor a-amylase also displaying the same amino acid residues involved in enzyme catalysis (Asp184, Glu220 and Asp285). Since AmyHha gene was mostly transcribed in the intestinal tract of H. hampei larvae, the cognate a-amylase could be considered a high valuable target to coffee bean insect control by biotechnological strategies.
