Because of the increasing demand of the industry for the production of essential oils, studies highlight the genetic variability of Piper hispidinervum and P. aduncum species according to their patterns of spatial distribution, showing the Amazon region as the source of superior genetic material in the production of safrole and dillapiole. Thus, the objective this study was to characterize the morphology and the phytochemistry of Piper hispidinervum and P. aduncum populations in the Active Germplasm Bank of Embrapa Acre to generate subsidies for the genetic improvement of these species. The results showed that the average values for leaf width and length were 141.67 and 48.04 mm, and petioles length and diameter measurements were 2.83 and 1.78 mm for P. hispidinervum and 189.22; 67.74; 6.03 and 2.22 mm for P. aduncum respectively. The average height and canopy volume measurements were 2.39 m and 6.30 m3 and 2.70 m and 7.78 m3 respectively for each species. For P. hispidinervum, the population with higher performance indried yield and content of safrole was population 02, with 3.9%, and the population 04 showed 94.3% safrole content, both with genetic material from the region of Acrelândia and Plácido de Castro. To P. aduncum, the populations with better performance were 207, 208 and 209, forming a homogeneous group with dried yield average of 3.8% and dillapiol content of 84-85%. Such populations are indicated for selection in breeding program of these species due to better performance.

The toxicity caused by aluminum (Al), intrinsic to acid soils, influences negatively the stability of crop production. Under toxic levels of Al, plant roots paralyze their development and become unable to explore the deeper layers of the soil, affecting nutrient and water acquisition and reducing crop yield. This study aimed to identify genes associated with Al tolerance mechanisms in grasses, using cDNA and subtractive libraries derived from roots of maize, rice, sorghum, oat, barley, wheat and brachiaria tolerant genotypes submitted to critical levels of Al in nutrient solution. We analyzed 5,304 sequences, of which 3,869 were considered of good quality (Phred score: 13 and minimum number of bases: 70). Additionally, 391 sequences without quality scores that showed similarities in BLASTn against public database sequences were added to the clustering process. A total of 4,260 quality sequences were clustered with CAP3, generating 567 contigs and 1,009 singletons. The contigs ranged from 2 to 92 sequences. BLAST2GO was used to determine the putative roles and ontologies of the sequences combining results from BLAST, InterProScan, Gene Ontology (GO), and KEGG metabolic pathways. Out of the 1,576 unique sequences (contigs + singletons), 953 received GO terms by BLAST2GO annotation. Al tolerance mechanisms are divided into two main types: (1) exclusion, which prevent the Al uptake into the cell; and (2) simplastic, that immobilize or neutralize the Al in specific locations inside the cells. Therefore, we focus our initial search in sequences associated with transport, biotic and abiotic stress, and membrane components. Next we searched for sequences related to organic acids compounds such as malate, citrate and oxalate. The "transport" term appears under GO terms in 113 unique sequences, "membrane" in 335, and "stress" in 45, while the combination of "transport and membrane" were found in 82, "membrane and stress" in 19, "transport and stress" in nine, and "stress, transport and membrane" in four. For organic compounds, "malate" appears under GO terms in four unique sequences, "citrate" in three and "oxalate" does not appear. Using KEGG, 12 sequences showed similarity with nine enzymes of the TCA cycle. A large number of genes were induced under Al stress in grass roots, including genes commonly found in other abiotic stresses. This strategy will allow us to identify Al tolerance mechanisms common to several grass species.
