“…Besides, salinity increases the reactive oxygen species (ROS) production and oxidative stress and reduces enzymatic or nonenzymatic ROS quenching activities, as a result, it causes mild to severe oxidative damage in cellular and membrane components such as DNA, proteins, and lipids ( Zhang et al., 2022 ; Sadak and Dawood, 2023 ). The salinity creates an imbalance in osmotic regulation that prevents or reduces water uptake, and Na and Cl ions toxicity are the identified explanations related to the adverse effect of salinity on germination and seedling growth ( Munns et al., 2006 ; Taha and Abd El-Samad, 2022 ). Furthermore, salinity affects the balance of primary metabolites such as total soluble sugars, reduced sugars, nonreducing sugars, starch, lipids, and proteins ( De Santis et al., 2021 ; Hussain et al., 2021 ; Kesh et al., 2022 ; Masarmi et al., 2023 ; Sadak and Dawood, 2023 ).…”

This study was conducted in controlled environmental conditions to systematically evaluate multi-traits responses of winter wheat (Triticum aestivum L.) genotypes to different salinity levels. Responses were assessed at the germination to early seedling stage (Experiment 1). Seeds of different genotypes (n=292) were subjected to three salinity levels (0 [control], 60, and 120 mM NaCl). Principal Component Analysis (PCA) revealed that among studied traits seedling vigor index (SVI) contributed more towards the diverse response of genotypes to salinity stress. Based on SVI, eight contrasting genotypes assumed to be tolerant (Gage, Guymon, MTS0531, and Tascosa) and susceptible (CO04W320, Carson, TX04M410211) were selected for further physio-biochemical evaluation at the booting stage (Experiment 2) and to monitor grain yield. Higher level of salinity (120 mM NaCl) exposure at the booting stage increased thylakoid membrane damage, lipid peroxidation, sugars, proline, and protein while decreasing photosynthesis, chlorophyll index, starch, and grain yield. Based on grain yield, the assumed magnitude of the genotypic response shown in Experiment 1 was not analogous in Experiment 2. This indicates the necessity of individual screening of genotypes at different sensitive growth stages for identifying true salinity-tolerant and susceptible genotypes at a particular growth stage. However, based on higher grain yield and its least percentage reduction under higher salinity, Guymon and TX04M410211 were identified as tolerant, and Gage and CO04W320 as susceptible at the booting stage, and their biparental population can be used to identify genomic regions for booting stage-specific salinity response.

The DUF1644 family is a highly conserved and functionally unknown protein family and has been demonstrated significantly improved the salt tolerance of rice (nonhalophytes). However, little is understood about the function of the DUF1644 gene in halophytes. Further studies are required to determine whether it has a similar function in halophyte species. In our study, the functions of ZmDUF1644 from halophyte Zoysia matrella Z123 species were investigated under salt stress. Phylogenetic analysis clustered ZmDUF1644 and OsSDIP361 in the same group, which function as a salttolerant genes in rice. Our experimental data suggested that the ZmDUF1644 gene significantly alleviated the growth inhibition of transgenic Arabidopsis thaliana seedlings caused by salt stress. The maximum root length, fresh weight, and photosynthetic pigment content of transgenic seedlings were obviously better than that of the wild type. Moreover, a relatively lower relative electrolyte leakage rate, toxic ion (Na + ) content, and Na + /K + ratios were also found in the transgenic line when compared with the wild type under salt stress. In conclusion, this study revealed that the ZmDUF1644 gene was overexpressed in Arabidopsis thaliana significantly enhancing the salt tolerance of seedlings. It is the first report on the functions of ZmDUF1644 from halophyte Zoysia matrella which has a similar function in halophyte species.
