“…Positive and negative correlations between the observed parameters indicate whether or not the investigated plant is stress-resistant. If negative correlations occur less often in the same plant than positive correlations, this suggests that the plant is salt-tolerant [ 74 ]. In our experiment, the correlation-network analysis revealed that salt-tolerant genotypes have a higher pe/ne ratio than salt-sensitive and salt-moderate genotypes ( Figure 8 B).…”

Salinity is an abiotic stress factor that reduces yield and threatens food security in the world’s arid and semi-arid regions. The development of salt-tolerant genotypes is critical for mitigating yield losses, and this journey begins with the identification of sensitive and tolerant plants. Numerous physiologic and molecular markers for detecting salt-tolerant wheat genotypes have been developed. One of them is proline, which has been used for a long time but has received little information about proline-related genes in wheat genotypes. In this study, proline content and the expression levels of proline-related genes (TaPTF1, TaDHN, TaSRG, TaSC, TaPIMP1, TaMIP, TaHKT1;4, TaGSK, TaP5CS, and TaMYB) were examined in sensitive, moderate, and tolerant genotypes under salt stress (0, 50, 150, and 250 mM NaCl) for 0, 12, and 24 h. Our results show that salt stress increased the proline content in all genotypes, but it was found higher in salt-tolerant genotypes than in moderate and sensitive genotypes. The salinity stress increased gene expression levels in salt-tolerant and moderate genotypes. While salt-stress exposure for 12 and 24 h had a substantial effect on gene expression in wheat, TaPTF1, TaPIMP1, TaMIP, TaHKT1;4, and TaMYB genes were considerably upregulated in 24 h. The salt-tolerant genotypes showed a higher positive interaction than a negative interaction. The TaPTF1, TaP5CS, TaGSK1, and TaSRG genes were found to be more selective than the other analyzed genes under salt-stress conditions. Despite each gene’s specific function, increasing proline biosynthesis functioned as a common mechanism for separating salt tolerance from sensitivity.

“…Solanum lycopersicum is described as a glycophyte species and S. chilense, as a halophyte species (Martıńez et al, 2014;Gharbi et al, 2018). Since hybrids had an intermediate phenotype between parents and some characteristics were closer to S. lycopersicum and others to S. chilense, we could therefore suspect that the physiological behavior of hybrids could be sometimes closer to halophyte behavior and sometimes closer to glycophyte behavior (Cano et al, 1996;Uwimana et al, 2012;Aycan et al, 2021). In addition, interspecific hybrids may have better fitness for some traits than their parents (Rhode and Cruzan, 2005;Kumar et al, 2020).…”

IntroductionSoil salinization is a major global problem. Tomato (Solanum lycopersicum) is one of the main crops produced in the world and is cultivated in areas affected by salinity. However, it is considered as a glycophyte species and is sensitive to salt stress. Solanum chilense is a wild tomato native to the Atacama Desert and is therefore adapted to harsh environmental conditions, including salinity. It is considered as a promising source of genes for tomato improvement. However, the physiology of abiotic stress resistance remains largely unknown in S. chilense and no studies have investigated the resistance of S. lycopersicum x S. chilense interspecific hybrids and the potential value of their use in harsh environments.MethodsIn this study, we compared the salt (0 vs. 100 mM NaCl) resistance of S. lycopersicum, S. chilense and their hybrids at vegetative and reproductive stages.ResultsOverall, hybrids showed an intermediate behavior between their parents and a higher salt resistance than S. lycopersicum. Their physiological behavior toward salt stress was sometimes closed to S. lycopersicum and sometimes closed to S. chilense. Their sodium accumulation was intermediate between parents, with a sodium concentration closer to S. lycopersicum than S. chilense in roots, but with an aerial concentration closer to S. chilense than to S. lycopersicum. In inflorescences and fruits, the sodium concentration of hybrids was closer to S. lycopersicum than to S. chilense. Despite a decrease in instantaneous transpiration, the photosynthetic nitrogen use efficiency of hybrids was not decreased by salt stress: our results suggest a greater tolerance to the osmotic phase of salt stress in hybrids compared to the parents. Regarding the reproductive stage, inflorescence production and fruit quality were not affected by salt in hybrids.DiscussionThis study highlights the potential use of hybrids in improving tomato for salt stress resistance.

Increasing biomass allocation to the root system may increase soil-organic carbon stocks and confer drought adaptation in water-limited environments. Understanding the genetic bases and inheritance of biomass allocation is fundamental for drought tolerance breeding and soil health. The objective of this study was to determine the general and specific combining ability, maternal effects and the mode of gene action controlling the major yield and biomass allocation related traits in wheat to identify good combiners for breeding and enhanced carbon sequestration. Ten selected wheat genotypes were crossed in a full diallel mating design, and 90 F2 families were generated and evaluated in the field and greenhouse under drought-stressed and non-stressed conditions. Significant differences were recorded among the tested families revealing substantial variation for plant height (PH), kernels per spike (KPS), root biomass (RB), shoot biomass (SB), total plant biomass (PB) and grain yield (GY). Additive gene effects conditioned PH, SB, PB and GY under drought, suggesting the polygenic inheritance for drought tolerance. Strong maternal and reciprocal genetic effects were recorded for RB across the testing sites under drought-stressed conditions. Line BW162 had high yield and biomass production and can be used to transfer favourable genes to its progeny. The parental line LM75 maintained the general combining ability (GCA) effects in a positive and desirable direction for SB, PB and GY. Early generation selection using PH, SB, PB and GY will improve drought tolerance by exploiting additive gene action under drought conditions. Higher RB production may be maintained by a positive selection of male and female parents to capture the significant maternal and reciprocal effects found in this study.
