... Our results were similar, as Gln and His were also significantly lower in the R versus S cultivar, yet different because Met, Tyr, and Asn were significantly lower in Harosoy 63. In comparison, another hemipteran, Megacopta cribraria (F.) (Plataspidae), was found to have higher nymph production when the concentrations of Asp, Try, Ala, Phe, and Ser were greater in soybean leaves; however, production was less when Leu and Thr levels were higher [32]. This indicates the effects that FAA type and quantity can have on soybean herbivores. ...
... and R. reniformis and resistant soybean lines have been identified (Rebois et al., 1968;Birchfield and Brister, 1969;Luzzi et al., 1987;Hussey et al., 1991;Robbins and Rakes, 1996;Robbins et al., 1999;Harris et al., 2003;Stetina et al., 2014;Klepadlo et al., 2018). Biparental linkage mapping and genomewide association studies showed that resistance to M. incognita and R. reniformis in soybean is a quantitative trait (Williams et al., 1981;Tamulonis et al., 1997;Li et al., 2001;Ha et al., 2007;Pham et al., 2013;Xu et al., 2013;Jiao et al., 2015;Passianotto et al., 2017;Li et al., 2018;Wilkes et al., 2020). However, resistance mechanisms and associated resistance genes are poorly understood. ...
... Soybean (Glycine max L. Merr), a C3 plant, is among the most important food staple, industrial, and feed crops of the world, whose primitive economic value is because of the high-quality oil and protein present in seed and the production of renewable fuel due to its energy potential (Thao and Tran 2012;FAO 2015). Soybeans, especially those grown in tropical and subtropical regions of the world, are often exposed to high-temperature stress (temperatures above 30°C), which severely affects the distribution, growth, yield, and quality of soybeans (Schlenker and Roberts 2009;Narayanan et al. 2020). High-temperature stress damages soybean leaves and directly affects photosynthesis and transpiration, and its persistence greatly reduces soybean yield (Narayanan et al. 2020). ...
... Resistance of Nitrasoy (a non-nodulating variety) was also tested in the greenhouse without any addition of fertilizer once the experiment was initiated. The soybean variety NC Raleigh was also included due to its known susceptibility to M. cribraria (Fritz et al. 2016, Lahiri et al. 2020. ...
... Both, MAS and GS increase the rate of genetic gain by reducing the necessary selection time for the desired traits. MAS-and GS-based programmes have been applied to improve yield in soybean (Concibido et al. 1997;Sebastian et al. 2010;Jarquín et al. 2014;Fallen et al. 2015;Stewart-Brown et al. 2019) and maize (Yousef and Juvik 2001;Liu et al. 2015;Pace et al. 2015;Beyene et al. 2015;Wang et al. 2020) and have enhanced disease resistance, yield, plant height and flowering time in wheat and rice (Gupta et al. 2010;Poland et al. 2012;Ragimekula et al. 2013;Spindel et al. 2015;Thavamanikumar et al. 2015;Borrenpohl et al. 2020). These molecular strategies are also applicable to oil palm. ...
... Patil et al. (2017) aptly reviewed and described modern genomic efforts to improve soybean protein content. More specifically, quantitative trait loci (QTL) have been identified for protein concentration (Panthee et al., 2005;Warrington et al., 2015) as well as amino acid profiles (Panthee et al., 2006a,b;Fallen et al., 2013;Warrington et al., 2015;Li et al., 2018). Direct breeding results from this research include the sole publicly developed United States soybean variety (TN04-5321) release with enhanced sulfur-containing amino acids concentrations (Panthee and Pantalone, 2006) and potential introgression of an allele for significantly increased protein content (Warrington et al., 2015). ...
... In China, Wu and Cai [14] discovered that a 1% increase in the grain subsidy caused a 0.096% increase in grain crop acreage. Besides the above factors, the availability of resources, type of farming, land titling, and location also had significant effects on crop choice [6,[15][16][17]. In general, farmers' crop decisions are complex as they are affected by individual characteristics and external drivers. ...
... Only the genotypes with high root penetrability of compacted soils will exhibit roots at deeper depths, and our data suggest that SC07-1518RR is one such genotype. The root penetrability of SC07-1518RR is supported by our previous research in which the same genotype penetrated a synthetic hardpan placed in the growth columns under controlled environmental conditions [79]. Deep rooting is especially advantageous for plants in drought years like 2019. ...
... Studies involving GS in plants have been mostly focused on prediction for advancement purposes, hence restricted to the evaluation of genetic gain within a single generation (Schmutz et al., 2010;Sonah et al., 2013;Jarquin et al., 2016;Xavier et al., 2016Xavier et al., , 2018aDiers et al., 2018;Smallwood et al., 2019). Studies of long-term gains based on GS are expensive and time-consuming; consequently, the literature is scarce (Wray and Goddard, 1994;Goddard, 2009;Yabe et al., 2016;Allier et al., 2019a). ...
... Several studies have highlighted inter-and intraspecific variation in the capacity of plant roots to overcome soil physical barriers [48]. Phenotypic variability in root penetrability has been shown in rice [66], soybean [67], wheat [68], cotton [69], and maize [54]. It was reported that eudicot species have a better penetration ability than monocot species as a result of a larger root diameter and maximum root growth pressure [48]. ...
