“…Plant anabolism is always weakened and catabolism is strengthened under stress conditions. This is because the amount of required energy for growth and development becomes insufficient, resulting in various physiological processes involving Ca 2+ are affected and hydrolysis of macromolecules in plants is enhanced (Gao et al 2019). Our results combined with these findings suggest that exogenous calcium could be added to salinization soils to restore the balance of saccharide metabolism and alleviate salt damage.…”

Soybean is one of the most important economic crops in the world. However, the salinization of soil results in the decrease of soybean yield as it is only a moderately salt-tolerant crop. We treated three soybean cultivars with low and high concentrations of NaCl. The differentially expressed genes between the control group and the salt treatment group were identified by mRNA sequencing and analyzed by gene ontology and Kyoto encyclopedia of genes and genomes annotations. We performed weighted gene co-expression network analysis on all samples and found genes most related to the phenotype. After verifying the results of differentially expressed genes by quantitative PCR, we finally identified Glyma06G01990, Glyma08G22730, Glyma019G05140, and Glyma06G20160 as key genes affecting the soybean growth under salt stress.

“…In addition to hormone-related genes, a diverse set of calcium-related genes were also found in the QTL regions, including some with potential binding, transport, and calcium-activated signal transduction functions. Calcium also has well-documented roles in signaling, water relations, and cell wall modification during fruit ripening in various fruit crops; therefore, these genes may also be underlying the variation of the traits (Conway and Sams, 1987; García et al, 1996; Pilar Hernandez et al, 2006; Ciccarese et al, 2013; Beaudry et al, 2016; Munir et al, 2016; Gao et al, 2019).…”

2Blueberry (Vacciunium corymbosum and hybrids) is an autotetraploid crop whose commercial 3 relevance has been growing steadily during the last twenty years. However, the ever-increasing 4 cost of labor for hand-picking blueberry is one main constraint in competitive marketing of the 5 fruit. Machine harvestability is, therefore, a key trait for the blueberry industry. Understanding 6 the genetic architecture of traits through quantitative trait locus (QTL) mapping is the first step 7 towards implementation of molecular breeding for faster genetic gains. Despite recent advances 8 in software development for autotetraploid genetic mapping, a high-resolution map is still not 9 available for blueberry. In this study, we crafted a map for autotetraploid low-chill highbush 10 blueberry containing 11,292 SNP markers and a total size of 1,953.97 cM (average density of 11 5.78 markers/cM). This map was subsequently used to perform QTL analyses for traits relevant 12 to machine harvesting: firmness, firmness retention, and fruit detachment force. Significant 13 QTL peaks were identified for all the traits. The QTL intervals were further explored for putative 14 candidate genes. Genes related to cell wall remodeling were highlighted in the firmness and 15 firmness retention intervals. For fruit detachment force, transcription factors involved in fruit 16 abscission were detected. Altogether, our findings provide the basis for future fine-mapping and 17 molecular breeding efforts for machine harvesting in blueberry. 18 Keywords: Vaccinium, southern highbush blueberry, firmness, detachment force, polyploid 19 20chromosomal alterations are not only tolerated by plant genomes, but can also drive evolution, for example, 21 promoting speciation (Adams and Wendel, 2005). Polyploid organisms are classified as either allopolyploids 22 or autopolyploids, depending on the degree of divergence between their subgenomes (Brubaker et al., 1999). 23 Autopolyploids, such as blueberry (Vaccinium corymbosum L.), potato (Solanum tuberosum L.), and alfalfa 24 (Medicago sativa L.), contain multiple copies of the same chromosome set, which can all pair and exchange 25 1 Cappai et al. QTL Map for Blueberry Harvest genetic material during gamete formation. In contrast, allopolyploids, such as wheat (Triticum aestivum 26 L.), coffee (Coffea arabica L.), and strawberry (Fragaria ananassa Duch.) contain two or more divergent 27 genomes, which usually show bivalent pairing and have disomic inheritance, like diploid organisms. 28 While in diploid systems the study of allelic inheritance is relatively simple, polysomic inheritance in 29 autopolyploids increases the number of possible genetic configurations and impacts downstream genetic 30 analyses, including linkage map construction and quantitative trait loci (QTL) mapping (Bever and Felber, 31 1992). 32 QTL mapping is the association study between phenotypic and genetic variants usually performed by 33 tracking recombination events of the possible QTL along chromosomes (Broman and Sen, 2009).

“…Nutrient translocation and distribution within the scion have significant implications on tree growth, fruit development, and fruit quality especially for Ca, which has long been the most important nutrient affecting fruit quality [160,161] (Figure 2D). Unlike Ca, other macronutrients are plant mobile and redistribution occurs during shorter periods of deficiencies.…”

Tree responses to fertilizer management are complex and are influenced by the interactions between the environment, other organisms, and the combined genetics of composite trees. Increased consumer awareness of the environmental impact of agriculture has stimulated research toward increasing nutrient-use efficiency, improving environmental sustainability, and maximizing quality. Here, we highlight recent advancements and identify knowledge gaps in nutrient dynamics across the soil–rhizosphere–tree continuum for fruit crops. Beneficial soil management practices can enhance nutrient uptake and there has been significant progress in the understanding of how roots, microorganisms, and soil interact to enhance nutrient acquisition in the rhizosphere. Characterizing root architecture, in situ, still remains one of the greatest research challenges in perennial fruit research. However, the last decade has advanced the characterization of root nutrient uptake and transport in plants but studies in tree fruit crops have been limited. Calcium, and its balance relative to other macronutrients, has been a primary focus for mineral nutrient research because of its important contributions to the development of physiological disorders. However, annual elemental redistribution makes these interactions complex. The development of new approaches for measuring nutrient movement in soil and plant systems will be critical for achieving sustainable production of high-quality fruit in the future.
