“…However, ion toxicity does not manifest itself until ions have accumulated to toxic levels in the tissues. 97 In the course of a long-term salt stress plant will produce a series of adaptive changes. Further investigation is needed to gain a comprehensive knowledge about genes and proteins that are selectively up-or down-regulated in response to short-term and long-term salt stress.…”

Salinity is a major abiotic stress affecting plant cultivation and productivity. Thellungiella halophila is a halophyte and has been used as a model for studying plant salt tolerance. Understanding the molecular mechanisms of salinity tolerance will facilitate the generation of salt tolerant crops. Here we report comparative leaf proteomics of Arabidopsis, a glycophyte, and its close relative Thellungiella, a halophyte, under different salt stress conditions. Proteins from control and NaCl treated Arabidopsis and Thellungiella leaf samples were extracted and separated by two-dimensional gel electrophoresis. A total of 88 protein spots from Arabidopsis gels and 37 protein spots from Thellungiella gels showed significant changes. Out of these spots, a total of 79 and 32 proteins were identified by mass spectrometry in Arabidopsis and Thellungiella, respectively. Most of the identified proteins were involved in photosynthesis, energy metabolism, and stress response in Arabidopsis and Thellungiella. As a complementary approach, isobaric tag for relative and absolute quantification (iTRAQ) LC-MS was used to identify crude microsomal proteins. A total of 31 and 32 differentially expressed proteins were identified in Arabidopsis and Thellungiella under salt treatment, respectively. Overall, there were more proteins changed in abundance in Arabidopsis than in Thellungiella. Distinct patterns of protein changes in the two species were observed. Collectively, this work represents the most extensive proteomic description of salinity responses of Arabidopsis and Thellungiella and has improved our knowledge of salt tolerance in glycophytes and halophytes.

“…Hence the reduction in K content due to excess Na is likely to be the result of the competitive intracellular influx of both ions [25]. It is generally accepted that increased K/Na selectivity and reduced Na translocation from roots to other aerial parts contributes the overall salt tolerance in glycophytes [26,27].…”

Varied levels of salinity in irrigation water remained a serious issue to shrink agricultural productivity in Saurashtra region of Gujarat. Groundnut, being a prominent crop in this zone, suffered to quite an extent due to induced salinity. In the present study, the authors have simulated a field condition where four different saline water of EC iw of 0.5, 2.0, 4.0, 6.0 dS m -1 were used for irrigation in groundnut (rainy/kharif)-cluster bean (summer) rotation. Both the crops were assessed by their respective growth and yield traits. A marked decrease was observed in seedling emergence, plant height, root length and pod yield at highest salinity, EC iw 6.0 dS m -1 whereas the same trend was noticed for plant height, dry weight of plant and final plant stand for cluster bean in the next season. However, pod yield of both the crops did not decrease up to EC iw 2.0 dS m -1 . The ionic imbalance in different plant parts is another major impact of salinity. Na showed enhanced accumulation in plant parts where groundnut roots accumulated 42.0 and 75.4 % higher than shoots and kernels, respectively at highest EC iw ; while other nutrients (N, P, Ca, K) showed a declining effect with increasing salinity.
