“…Both SCwSAPs (New_SC and Com_SC) outperformed the results obtained with pure SAP by Clemente et al (2004), who found that 100 g seedling -1 dose had no effect on seedling performance. This better performance of SCwSAP compared to pure SAP at higher doses could be related to its synergistic mixture of SAP with other components (fertilizers, humic acids, root growth precursors), as suggested in nursery conditions (Vieira et al 2005;Machado et al 2016). Future field studies could assess the effect of each SCwSAP on seedling and soil nutrient status.…”

“…In general seedlings respond well to treatments with soil conditioners and fertilizers, although no significant differences in terms of plant traits (e.g., plant height, stem diameter, number of leaves, shoot dry matter, leaf area index, and root dry matter) were found when applying different organic and chemical fertilizer treatments (Machado et al 2016;Pimentel et al 2016). Observations indicate that the combined application of chemical fertilizers and soil conditioners on clayey and sandy soils increases nutrient levels of A. aculeata seedlings' leaves and soils, as well as soil organic matter and microbial biomass carbon (Machado et al 2016). Quarterly top dressing and surrounding with a thermo-reflective screen are recommended during the nursery process (Costa et al 2014;Pimentel et al 2016).…”

Acrocomia spp., a genus of wild-growing palms in the neotropics, is rapidly gaining interest as a promising multipurpose crop. Diverse products can be derived from various components of the palm, the oils being of highest interest. Acrocomia shows similar oil yield and fatty acid composition to the African oil palm (Elaeis guineensis). It is, however, able to cope with a wider range of environmental conditions, including temporary water scarcity and lower temperatures, thus potentially a more sustainable alternative to its tropical counterpart. Acrocomia’s research history is recent compared to other traditional crops and thus knowledge gaps, uncertainty, and challenges need to be addressed. This review attempts to assess the acrocomia’s preparedness for cultivation by highlighting the state-of-the-art in research and identifying research gaps. Based on a systematic literature search following a value web approach, it (a) provides a comprehensive overview of research topics, (b) shows the development of publication activities over time and the drivers of this development, and (c) compiles main findings to assess the acrocomia’s preparedness for commercial cultivation. Our results confirm its multipurpose characteristic as a potential feedstock for manifold sectors. Research has continued to increase over the last decade, especially on A. aculeata and is driven by the interest in bioenergy. Increasing knowledge on botany has contributed to understanding the genetic diversity and genus-specific biology. This has enabled applied research on seed germination and propagation toward domestication and initial plantation activities, mostly in Brazil. Main research gaps are associated with genotype–environment interaction, planting material, crop management, and sustainable cropping systems. Overall, we conclude that acrocomia is at an early phase of development as an alternative and multipurpose crop and its up-scaling requires the integration of sustainability strategies tailored to location-based social-ecological conditions.

“…Due to its attractive features, the macaw palm domestication, genetic breeding and development of commercial plantations have encouraged financial investments in basic research, biotechnology and industry. Studies in several areas have been carried out with this purpose, including ecophysiology (Pires et al 2013), mating system (Lanes et al 2016), vegetative development (Berton et al 2013;Machado et al 2016), fruit development (Montoya et al 2016), phenotypic diversity (Ciconini et al 2013;Lanes et al 2015;Conceição et al 2015;Coser et al 2016) and biotechnological applications (Moura et al 2009;Luis and Scherwinski-Pereira 2014;Padilha et al 2015).…”

The plastome of macaw palm was sequenced allowing analyses of evolution and molecular markers. Additionally, we demonstrated that more than half of plastid protein-coding genes in Arecaceae underwent positive selection. Macaw palm is a native species from tropical and subtropical Americas. It shows high production of oil per hectare reaching up to 70% of oil content in fruits and an interesting plasticity to grow in different ecosystems. Its domestication and breeding are still in the beginning, which makes the development of molecular markers essential to assess natural populations and germplasm collections. Therefore, we sequenced and characterized in detail the plastome of macaw palm. A total of 221 SSR loci were identified in the plastome of macaw palm. Additionally, eight polymorphism hotspots were characterized at level of subfamily and tribe. Moreover, several events of gain and loss of RNA editing sites were found within the subfamily Arecoideae. Aiming to uncover evolutionary events in Arecaceae, we also analyzed extensively the evolution of plastid genes. The analyses show that highly divergent genes seem to evolve in a species-specific manner, suggesting that gene degeneration events may be occurring within Arecaceae at the level of genus or species. Unexpectedly, we found that more than half of plastid protein-coding genes are under positive selection, including genes for photosynthesis, gene expression machinery and other essential plastid functions. Furthermore, we performed a phylogenomic analysis using whole plastomes of 40 taxa, representing all subfamilies of Arecaceae, which placed the macaw palm within the tribe Cocoseae. Finally, the data showed here are important for genetic studies in macaw palm and provide new insights into the evolution of plastid genes and environmental adaptation in Arecaceae.
