“…A further increase in the salinity stress level can inhibit plant growth, with significantly lower above-and underground biomasses. This result was in agreement with several previous studies on different plants [19,39,44]. Wassan et al [39] analyzed a panel of 228 B. napus accessions (197 semi-winter types, 9 spring types) and found that a 50 mM NaCl treatment increased the average shoot dry weight (by ~30%) and average root length (by ~2%) of the sevenday-old seedlings compared to the controls.…”

Oilseed rape (Brassica napus L.), an important oil crop of the world, suffers various abiotic stresses including salinity stress during the growth stage. While most of the previous studies paid attention to the adverse effects of high salinity stress on plant growth and development, as well as their underlying physiological and molecular mechanisms, less attention was paid to the effects of moderate or low salinity stress. In this study, we first tested the effects of different concentrations of NaCl solution on the seedling growth performance of two oilseed rape varieties (CH336, a semi-winter type, and Bruttor, a spring type) in pot cultures. We found that moderate salt concentrations (25 and 50 mmol L−1 NaCl) can stimulate seedling growth by a significant increase (10~20%, compared to controls) in both above- and underground biomasses, as estimated at the early flowering stage. We then performed RNA-seq analyses of shoot apical meristems (SAMs) from six-leaf-aged seedlings under control (CK), low (LS, 25 mmol L−1), and high (HS, 180 mmol L−1) salinity treatments in the two varieties. The GO and KEGG enrichment analyses of differentially expressed genes (DEGs) demonstrated that such a stimulating effect on seedling growth by low salinity stress may be caused by a more efficient capacity for photosynthesis as compensation, accompanied by a reduced energy loss for the biosynthesis of secondary metabolites and redirecting of energy to biomass formation. Our study provides a new perspective on the cultivation of oilseed rape in saline regions and new insights into the molecular mechanisms of salt tolerance in Brassica crops. The candidate genes identified in this study can serve as targets for molecular breeding selection and genetic engineering toward enhancing salt tolerance in B. napus.

“…However, not all studies confirm the obligatory halophytic nature of M. crystallinum . When 40-day-old vermiculite-cultivated plants were treated with 100 mM NaCl for two weeks, a significant reduction in growth was evident [ 21 ]. However, no significant effect from a similar treatment was seen for the treatment of 55-day-old plants.…”

“…The plant has unique adaptive properties, allowing it to withstand high substrate salinity and episodes of water shortages, including the presence of epidermal bladder cells on shoots that act as water and salt reservoirs as well as an inducible transition from a C 3 - to a Crassulacean acid metabolism (CAM)-type of photosynthetic carbon fixation [ 9 ]. The species has emerged as a model plant in studies aimed at understanding the molecular mechanisms of salinity tolerance [ 10 , 11 , 12 , 13 , 14 ] as well as in respect to its use as a halophytic crop species for salinized soils or in cultivation systems using seawater [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. In addition, its heavy metal tolerance and accumulation potential have been studied [ 23 , 24 , 25 , 26 ].…”

Mesembryanthemum crystallinum L. is an obligatory halophyte species showing optimum growth at elevated soil salinity levels, but the ionic requirements for growth stimulation are not known. The aim of the present study was to compare the effects of sodium, potassium and calcium in the form of chloride and nitrate salts on the growth, physiological performance, ion accumulation and mineral nutrition of M. crystallinum plants in controlled conditions. In a paradoxical way, while sodium and potassium had comparable stimulative effect on plant growth, the effect of calcium was strongly negative even at a relatively low concentration, eventually leading to plant death. Moreover, the effect of Ca nitrate was less negative in comparison to that of Ca chloride, but K in the form of nitrate had some negative effects. There were three components of the stimulation of biomass accumulation by NaCl and KCl salinity in M. crsytallinum: the increase in tissue water content, increase in ion accumulation, and growth activation. As optimum growth was in a salinity range from 20 to 100 mM, the increase in the dry biomass of plants at a moderate (200 mM) and high (400 mM) salinity in comparison to control plants was mostly due to ion accumulation. Among physiological indicators, changes in leaf chlorophyll concentration appeared relatively late, but the chlorophyll a fluorescence parameter, Performance Index Total, was the most sensitive to the effect of salts. In conclusion, both sodium and potassium in the form of chloride salts are efficient in promoting the optimum growth of M. crystallinum plants. However, mechanisms leading to the negative effect of calcium on plants need to be assessed further.

“…Ice plant ( Mesembryanthemum crystallinum , Aizoaceae) is a vegetable crop consumed in India, Australia, New Zealand, and some European countries [ 6 , 7 ]. It is native to southern and eastern Africa and is now distributed worldwide [ 8 ]. The succulent leaves are coated with enlarged epidermal cells and provide a slightly salty taste.…”

Recent assessments of the correlations between food and medicine underscore the importance of functional foods in disease prevention and management. Functional foods offer health benefits beyond basic nutrition, with fresh fruits and vegetables being particularly prominent because of their rich polyphenol content. In this study, we elucidated the phytochemicals in ice plant (Mesembryanthemum crystallinum), a globally consumed vegetable, using an LC-QTOF/MS-based untargeted detection method. The phytochemicals were clustered based on their structural similarity using molecular networking and annotated using the in silico tool for network annotation propagation. To identify the bioactive compounds, eight compounds were isolated from ice plant extracts. These compounds were identified using extensive spectroscopic methods, including 1H and 13C nuclear magnetic resonance (NMR) spectroscopy. Additionally, we evaluated the antioxidant and anti-inflammatory activities of all the isolates. Among the tested compounds, three showed antioxidant activity and all eight showed anti-inflammatory activity, demonstrating the potential of ice plant as a functional food.
