“…Advancements have enabled a more effective production of feijoa in Brazil, especially regarding its management (Coradin et al, 2012). Studies also focused on the species' genetics (Borsuk et al, 2017, Klabunde et al, 2014 and morphological aspects (Sarmento et al, 2018). Nonetheless, studies on its cultivation and development in Brazil are still scarce (Nava et al, 2016).…”

Feijoa sellowiana (O.Berg) O. Berg is an ornamental and food plant, as well as an important species for ecological restoration and landscaping that still requires much research before consolidating it in the tropical market. To understand if the implementation of techniques focusing on improving fruit production at its wild condition would affect the species’ development, we planted 216 saplings of various mother trees in an incomplete factorial block design applied in nine treatments. We tested formative aerial pruning (drastic intensity), fertilization (chemical and organic), and the effect of controlled fires prior to planting. We evaluated biomass alterations by systematically measuring the third sapling of each treatment, quantifying fresh and dry matter in two periods. We also measured changes in height (H), root collar diameter (RCD), and the H/RCD ratio. We carried out nine measurements during 27 months and used linear mixed-effects models to consolidate the long-term evaluation. Our results indicate a positive effect from the organic fertilization on the plants’ height, a momentary increase in RCD caused by programmed fires, and an increase in the H/RCD ratio due to formative aerial pruning (increasing resistance). Fertilization did not accelerate the increase in RCD and had no effect on the H/RCD ratio.

“…As a minor crop, genomic resources in A. sellowiana are limited and not yet useful in breeding programs. Few studies document the molecular diversity of the species using lowthroughput molecular markers (Dettori and Palombi, 2000;dos Santos et al, 2007;Pasquariello et al, 2015;Donazzolo et al, 2020;Saifert et al, 2020) and a limited number of molecular markers have been specifically designed for A. sellowiana (dos Santos et al, 2008;Klabunde et al, 2014). Amplified fragment length polymorphisms (AFLP), intersimple sequence repeat (ISSR), and a small number of simple sequence repeats (SSR) markers were used in the construction on the first genetic map of the species (Quezada et al, 2014).…”

Frontiers is more than just an open-access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers Journal SeriesThe Frontiers Journal Series is a multi-tier and interdisciplinary set of open-access, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers Journal Series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to QualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation.

Construction of a High-Density Genetic Map of Acca sellowiana (Berg.) Burret, an Outcrossing Species, Based on Two Connected Mapping Populations

et al. 2021

Acca sellowiana, known as feijoa or pineapple guava, is a diploid, (2n = 2x = 22) outcrossing fruit tree species native to Uruguay and Brazil. The species stands out for its highly aromatic fruits, with nutraceutical and therapeutic value. Despite its promising agronomical value, genetic studies on this species are limited. Linkage genetic maps are valuable tools for genetic and genomic studies, and constitute essential tools in breeding programs to support the development of molecular breeding strategies. A high-density composite genetic linkage map of A. sellowiana was constructed using two genetically connected populations: H5 (TCO × BR, N = 160) and H6 (TCO × DP, N = 184). Genotyping by sequencing (GBS) approach was successfully applied for developing single nucleotide polymorphism (SNP) markers. A total of 4,921 SNP markers were identified using the reference genome of the closely related species Eucalyptus grandis, whereas other 4,656 SNPs were discovered using a de novo pipeline. The individual H5 and H6 maps comprised 1,236 and 1,302 markers distributed over the expected 11 linkage groups, respectively. These two maps spanned a map length of 1,593 and 1,572 cM, with an average inter-marker distance of 1.29 and 1.21 cM, respectively. A large proportion of markers were common to both maps and showed a high degree of collinearity. The composite map consisted of 1,897 SNPs markers with a total map length of 1,314 cM and an average inter-marker distance of 0.69. A novel approach for the construction of composite maps where the meiosis information of individuals of two connected populations is captured in a single estimator is described. A high-density, accurate composite map based on a consensus ordering of markers provides a valuable contribution for future genetic research and breeding efforts in A. sellowiana. A novel mapping approach based on an estimation of multipopulation recombination fraction described here may be applied in the construction of dense composite genetic maps for any other outcrossing diploid species.
