“…Confocal study also indicated that salt stress increases the damage and death of roots cells. Similar reports of reduction of plant growth under saline conditions have been observed in Vigna aconitifolia L. [53], Raphanus sativus L. [54], and Vigna unguiculata L. [55] Oryza sativa [56] and in tomato seedlings [57]. The number of nodules per root system also showed a significant decline with increasing level of sodium chloride in soil.…”

Salinity is one of the most severe abiotic stresses for crop production. The present study investigates the salinityinduced modulation in growth indicators, morphology and movement of stomata, photosynthetic pigments, activity of carbonic anhydrase as well as nitrate reductase, and antioxidant systems in two varieties of chickpea (Pusa-BG5023, and Pusa-BGD72). On 20 th day of sowing, plants were treated with varying levels of NaCl (0, 50, 100, 150 and 200 mM) followed by sampling on 45 days of sowing. Recorded observations on both the varieties reveal that salt stress leads to a significant decline in growth, dry biomass, leaf area, photosynthetic pigments, protein content, stomatal behavior, cell viability, activity of nitrate reductase and carbonic anhydrase with the rise in the concentration of salt. However, quantitatively these changes were less in Pusa-BG5023 as compared to Pusa-BGD72. Furthermore, salinity-induced oxidative stress enhanced malondialdehyde content, superoxide radicals, foliar proline content, and the enzymatic activities of superoxide dismutase, catalase, and peroxidase. The variety Pusa-BGD72 was found more sensitive than Pusa-BG5023 to salt stress. Out of different graded concentrations (50, 100, 150 and 200 mM) of sodium chloride, 50 mM was least toxic, and 200 mM was most damaging. The differential behavior of these two varieties measured in terms of stomatal behavior, cell viability, photosynthetic pigments, and antioxidant defense system can be used as prospective indicators for selection of chickpea plants for salt tolerance and sensitivity.

“…These adverse physio-biochemical and molecular conditions simultaneously leads to inhibits plant growth, and its development. Many crops and vegetables, such as Vigna aconitifolia [6], Beta vulgaris [7] and Avena sativa [8], are very sensitive to salt stress. In addition, salt stress adversely affects the growth and development of many woody plants, such as Populus [9], Eucalyptus grandis [10] and Camellia sinensis [11], reducing the yield and quality of plants and causing very large economic losses.…”

Background: Salinity is the main abiotic stress that affects seed germination, plant growth and crop production. Plant growth begins with seed germination, which is closely linked to crop development and final yields. Morus alba L. is a well-known saline-alkaline tree with economic value in China, and the most prominent method of expanding mulberry tree populations is seed propagation. Understanding the molecular mechanism of Morus alba L. salt tolerance is crucial for identifying salt-tolerant proteins in seed germination. Here, we explored the response mechanism of mulberry seed germination to salt stress at physiological and protein omics levels. Methods: Tandem mass tag (TMT)-based proteomic profiling of Morus alba L. seeds germinated under 50 mM and 100 mM NaCl treatment for 14 days was performed, and the proteomic findings were validated through parallel reaction monitoring (PRM). Results: Physiological data showed that salt stress inhibited the germination rate and radicle length of mulberry seeds, decreased the malondialdehyde (MDA) content and significantly increased superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) activities. Then, a TMT marker technique was used to analyze the protein groups in mulberry seeds with two salt treatment stages, and 76,544 unique peptides were detected. After removing duplicate proteins, 7717 proteins were identified according to TMT data, and 143 (50 mM NaCl) and 540 (100 mM NaCl) differentially abundant proteins (DAPs) were screened out. Compared with the control, in the 50 mM NaCl solution, 61 and 82 DAPs were upregulated and downregulated, respectively, and in the 100 mM NaCl solution, 222 and 318 DAPs were upregulated and downregulated, respectively. Furthermore, 113 DAPs were copresent in the 50 mM and 100 mM NaCl treatments, of which 43 were upregulated and 70 were downregulated. Gene Ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that the DAPs induced by salt stress during mulberry seed germination were mainly involved in photosynthesis, carotenoid biosynthesis and phytohormone signaling. Finally, PRM verified five differentially expressed proteins, which demonstrated the reliability of TMT in analyzing protein groups. Conclusions: Our research provides valuable insights to further study the overall mechanism of salt stress responses and salt tolerance of mulberry and other plants.
