“…Based on our results, the tomato genotypes varied remarkably in their response to salt stress. There are several similar studies dealing with genotype selection for salt tolerance at the seedling stage in tomato [27], chicory [29], cotton [30], and rice [31,32]. According Zaki and Yokoi [27], the salt adaptability of seedlings at this stage may reflect higher salinity tolerance at advanced plant stages.…”

Salt stress is considered as one of the most frequent factors limiting plant growth and productivity of crops worldwide. The aim of the study was to evaluate physiological and biochemical responses of nine diverse tomato genotypes exposed to salt stress. In this regard, four-week-old seedlings of one modern variety, five landraces, the salt-sensitive accession of ‘Ailsa Craig’, the salt-tolerant wild accession of S. pimpinellifolium ‘LA1579’, as well as the vitamin C-rich S. pennellii introgression line ‘IL12-4’, were exposed to moderate salt stress (200 mM NaCl) for 10 days. At the end of the stress treatment, agronomical traits and stress indices were evaluated, while gas exchange-related parameters, root electrolyte leakage, malondialdehyde content and ascorbic acid were also determined. All parameters were significantly affected by salt stress, but to a different extent, verifying the diverse degree of tolerance within the selected genotypes, and further highlighting the different stress-induced mechanisms. The landrace originated from ‘Santorini’ island, as well as the modern variety, which originated from traditional cultivars, demonstrated a better performance and adaptivity under moderate salt stress, accompanied by reduced lipid peroxidation and enhanced ascorbic acid content, indicating that they could be potential promising genetic material for breeding programs or as grafting rootstocks/scions.

“…In our study, the leaf abscission sensitivity evaluation of cotton genotypes and treatments of different concentrations was evaluated by MFV. MFV analysis was used to evaluate salt and drought tolerance in distinct crops [ 21 , 22 , 23 ]. The accuracy of the evaluation results largely depends on the weighting method and the PCA method is used for determining the contribution rate of the principal components of this study.…”

“…So far, there is a lack of quantitative evaluation method for abscission sensitivity in cotton against TDZ treatment.The fuzzy comprehensive evaluation method has been applied to plant stress researches [ 18 , 19 ], and the method transforms qualitative evaluation into quantitative evaluation according to the membership theory of fuzzy mathematics. Membership function value (MFV) analysis was used to evaluate salt tolerance germplasm, selecting the optimal salt concentration and the reliable salt tolerance indexes in Brassica napus [ 20 ], Gossypium hirsutum L [ 21 ], and Sorghum bicolor (L.) [ 22 ]. MFV analysis was also applied to assess drought tolerance in Triticum aestivum L. [ 23 ] and Millet Germplasm ( Panicum miliaceum and Setaria italica ) [ 19 ].…”

Chemical defoliation is an essential agricultural practice in cotton production for mechanic harvesting. Thidiazuron (TDZ) is the active ingredient of the chemical defoliant used on cotton. So far, few studies havefocused on the method of identifying the sensitivity of cotton cultivars to TDZ. Therefore, a greenhouse soil culture experiment was performed by using two widely cultivatedupland cotton cultivars CRI 49 and CRI 12 treated with seven different concentrations (0, 100, 200, 300, 400, 500, and 1000 mg L−1) of TDZ at the seedling stage to establish a screening system. Principal component analysis and the membership function value (MFV) method was used to analyze the physiological and phenotypic characters, including abscission rate, amino acids content, net photosynthetic rate (Pn), etc. Finally, we developed a mathematical evaluation model, selected 100 mg L−1 TDZ as the optimal concentration and identified reliable characters net photosynthetic rate (Pn), stomatal conductance (Gs), and transpiration rate (Tr) to evaluate cotton leaf abscission sensitivity. These results also confirmed that CRI 12 was more sensitive to TDZ than CRI 49. This is the first time using a mathematical evaluation method to evaluate the cotton leaf abscission sensitivity triggered by TDZ at the seedling stage and the results were also confirmed in the field experiment. Furthermore, it will be valuable that MFV method is applied to stress sensitivity evaluation in other crop species under stress environment.

“…It is very important to improve salt tolerance based on ensuring high yield and quality in cotton. Transcriptome and proteome have made progress in revealing the mechanism of salt tolerance and identifying candidate genes in cotton (Gong et al 2017;Guo et al 2015;Li et al 2015;Peng et al 2014;Shan et al 2019;Sikder et al 2020;Yang et al 2019). As there are multi-level regulatory machineries exist in saltstress response, including transcription and translation regulations, it is important to monitor the gene expression level of RNA and protein simultaneously.…”

Background Soil salt stress seriously restricts the yield and quality of cotton worldwide. To investigate the molecular mechanism of cotton response to salt stress, a main cultivated variety Gossypium hirsutum L. acc. Xinluzhong 54 was used to perform transcriptome and proteome integrated analysis. Results Through transcriptome analysis in cotton leaves under salt stress for 0 h (T0), 3 h (T3) and 12 h (T12), we identified 8 436, 11 628 and 6 311 differentially expressed genes (DEGs) in T3 vs. T0, T12 vs. T0 and T12 vs. T3, respectively. A total of 459 differentially expressed proteins (DEPs) were identified by proteomic analysis, of which 273, 99 and 260 DEPs were identified in T3 vs. T0, T12 vs. T0 and T12 vs. T3, respectively. Metabolic pathways, biosynthesis of secondary metabolites, photosynthesis and plant hormone signal transduction were enriched among the identified DEGs or DEPs. Detail analysis of the DEGs or DEPs revealed that complex signaling pathways, such as abscisic acid (ABA) and jasmonic acid (JA) signaling, calcium signaling, mitogen-activated protein kinase (MAPK) signaling cascade, transcription factors, activation of antioxidant and ion transporters, were participated in regulating salt response in cotton. Conclusions Our research not only contributed to understand the mechanism of cotton response to salt stress, but also identified nine candidate genes, which might be useful for molecular breeding to improve salt-tolerance in cotton.
