Among the most targeted species for obtaining palm hearts, Euterpe edulis, popularly known as Juçara palm hearts, stands out and is threatened with extinction. The rational use of other palm trees for the production of palm hearts has been one of the alternatives to reduce the pressure of exploitation on the juçara palm: Archontophoenix alexandrae,...

... been exploited for human consumption, for the production of Açaí from the fruits or extraction of palm heart. Among many examples from Brazil, two palm trees are cultivated: Euterpe oleracea and E. edulis (Figure 2). The fruits of both species are important in terms of food resources for birds in their original areas (GENINI et al., 2009). ...

... should be done during the rainy season, avoiding the hottest and driest periods. A phosphorus-based planting fertilization should be carried out, since most Brazilian soils are deficient in this nutrient, with recommendations for amounts of 400-500 kg of simple superphosphate/ha, which should be incorporated into the soil in the pit (FRASSON; LOPES, 2002). The topdressing fertilization should be divided 3 times a year, to provide nitrogen and potassium, the amounts of which should be calculated after a chemical analysis of the soil (ABRAPALMER, 2017). ...

... valuing the waste generated is an attractive alternative to generate business development in the sector, in line with sustainability concepts, such as principles of non-waste generation (MCDONOUGH;BRAUNGART, 2002). Therefore, the canned palm heart process generates an amount of waste that is deposited at the harvesting site, and among the works proposed for the recovery of the residue are: the application of palm sheaths for the production of hydrolytic enzymes by fungi of the genus Polyporus ( ISRAEL, 2005) used in food and beverage industries, as well as in textile and cleaning product industries; obtaining food products such as fibrous biscuits (VIEIRA, 2006); or as substrates in the cultivation of fungi of the species Pycnoporus sanguineus (BORDERES, 2006) and Lentinula edodes, which are used for edible purposes, bioremediation or effluent treatment. ...

Palm trees (Arecaceae) are among the most important plants in the world, providing food and subsistence for various populations, especially in the Amazon region. Many of these trees depend on pollinators to produce fruits. In this study, we evaluated the pollination service values in 13 palm crops in the Brazilian Legal Amazon based on the agricult...

Red ring disease (RRD), caused by the nematode Bursaphelenchus cocophilus, is a devastating disease affecting oil palm and coconut plantations. In Brazil, it is a major constraint to oil palm production. This study employed single- and multi-omics approaches to comprehensively characterize the metabolome, transcriptome, and proteome of stipe tissue in adult oil palm (Elaeis guineensis Jacq.) plants exhibiting RRD symptoms. The objective was to identify unique biomarkers associated with the nematode for developing rapid and accurate diagnostic assays. Additionally, the study aimed to elucidate plant-pathogen interactions and identify potential targets for genetic resistance by identifying differentially expressed genes and proteins during infection. A resource of 397 putative nematode transcripts was established, demonstrating potential for PCR-based diagnostics in oil palm and other susceptible palm species. Pathway analysis integrated multi-omics data, revealing metabolic perturbations induced by the disease. For instance, the production of acetaldehyde and ethanol, compounds with nematicidal properties, suggests a potential plant defense mechanism used by the host. Transcriptomic analysis identified 1278 differentially expressed proteins, providing a foundation for selecting candidate genes to develop genetically modified or edited oil palm varieties with enhanced RRD resistance.
