“…Fresh leaves from a young macaw palm plant were collected and kept for 1 week at 4 °C to decrease starch level. The young plant was obtained from seeds of macaw palm plants belonging to the ex situ plant collection, Macaúba Active Germplasm Bank (BAG-Macaúba repository: 084/2013/ CGEN/MMA) located in the experimental farm of the Universidade Federal de Viçosa (208400100S, 4283101500W), State of Minas Gerais, Brazil (Coser et al 2016;Lanes et al 2015;Lanes et al 2016;Mengistu et al 2016a, b;Montoya et al 2016).…”

“…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.

“…The above-mentioned statistical software were used to identify the models of variability between genotypes and the relationship between different clusters of particular traits (Akhtar et al, 2010;Iqbal et al, 2014;Saeed et al, 2014). In order to estimate the genetic diversity for breeding of different traits in various crops, similar statistical methods have been used successfully in many breeding programs (Coser et al, 2016).…”

ABSTRACT. In Pakistan, cotton crop has been under enormous threat of cotton leaf curl disease (CLCuD) over the last four decades. In order to estimate genetic diversity in cotton germplasm CLCuD resistance, we assessed 100 cotton genotypes for their CLCuD resistance/tolerance and other related agronomical traits. Various statistical analytical tools, including correlation analysis, cluster analysis, and principal component analysis (PCA), were used to select the best genotypes. These genotypes can be used in future breeding programs to generate CLCuD resistant varieties. The same set of procedures could be utilized for other diseases in other crops. CLCuD incidence showed a significant negative genotypic correlation with yield-contributing traits followed by a significant negative association for phenotypic correlation. The seed cotton yield showed significant positive genotypic and phenotypic correlations with plant height, number of bolls per plant, and boll 2 M. Javed et al. Genetics and Molecular Research 16 (1): gmr16019446 weight. From the PCA we identified five principal components (PCs) that explained a significant amount of the variance among the variables, which may be used for selection of cotton genotypes with CLCuD resistance. Of the five PCs, the first four contributed more towards the total variability and had eigenvalues greater than one. The cluster analysis showed that the genotypes in one of the clusters performed particularly well with respect to CLCuD tolerance. These genotypes can be utilized for development of varieties with increased CLCuD tolerance.

“…Fruit yield grew over the years in all the predicted scenarios (Table 4) program. Consequently, the base population choice and the mother plant selection methods for the cuttings would be decisive as regards the increase in fruit productivity of the macauba crop over the years (Berton et al 2013;Coser et al 2016;Montoya et al 2016;Castro et al 2017).…”

Simulation of macauba palm cultivation: an energy-balance and greenhouse gas emissions analysis The expansion of the production and use of bioenergy is deemed as one of the most efficient mechanisms to reduce greenhouse gas (GHG) emissions. Nevertheless, the environmental impact of the production processes for many raw materials remains unexplored. Several studies have pointed to macauba palm (Acrocomia aculeata (Jacq.) Lodd. ex Mart.) as a promising species for biofuel production in the tropics, but investigations on the environmental benefits of the cultivation of this palm as a source of raw material for biofuel production have not been reported so far. The aim of this work has been to conduct an analysis of macauba production system in terms of GHG emissions and CO 2 uptake for a productive cycle, considering a 30-year horizon. The energy conversion efficiency (energy outputs/inputs ratio) per unit area of land has been put in relationship with crop productivity and related to the dilution effect of production inputs. Results of the simulation estimate that GHG emissions from macauba crop would be around 180 Mg CO 2 eq•ha-1 , whereas CO 2 fixation during cultivation would range from 796 to 1137 Mg CO 2 eq•ha-1. The energy assessment shows that the net energy balance for macauba crop would reach 512.3 GJ•ha-1 and that the energy efficiency would be ca. 24.2 GJ•GJ-1. These results, compared with those of traditional energy crops such as sugarcane, oil palm, sunflower, corn or jatropha, suggest that macauba crop may have the potential to outperform them in terms of efficiency. The domestication and exploitation in extensive farming of this species as an agroforestry crop, although still at an early stage, has a bright future.
