“…The synthesis of phenolic metabolites is considered to be as one of the first counter measures to maintain the redox homoeostasis in a plant's response to oxidative stress. For instance, an affinity towards up-regulation of PAL genes was observed in tolerant genotype of grapevines (Vitis vinifera L.) to 50 mM NaCl, highlighting the strong relation between the enhancement of the expression profile of PAL and the degree of plant salinity tolerance (Mohammadkhani et al 2016). In the same way, Yan et al 2016 revealed that salt (150 mM and 300 mM NaCl) enhanced chlorogenic acid synthesis in honeysuckle plants (Lonicera japonica Thunb.…”

Changes in the antioxidant defence systems were investigated in many aromatic and medicinal plants grown under salinity; however, no study is available about its effects on Solanum villosum Mill. In this study, we investigated the response of S. villosum to sodium chloride (NaCl), especially the impacts of NaCl on secondary metabolites production (phenolic compounds, carotenoids, and glycol-alkaloids). For this purpose, a hydroponic culture experiment was conducted on seedlings subjected to 0, 50, 100, or 150 mM NaCl. NaCl affected the growth of S. villosum in terms of plant height and dry weight, however, it increased the water content of the leaves. Although leaf Na + concentration was significantly increased under salt stress, the leaves K + , Ca 2+ and Mg 2+ concentration were enhanced and/ or not significantly affected. The adaptation of S. villosum to NaCl stress was also reflected by the maintain of chlorophyll levels under different NaCl treatments. Additionally, leaf caffeic acid, lutein, and beta-carotene contents were considerably increased under 100 mM NaCl treatment, along with the up regulation of some related phenolic (phenylalanine ammonialyase and flavonol synthase), and carotenoid genes (phytoene synthase 1, phytoene synthase 2, and b-lycopene cyclase). The leaf contents of β-solamargine and α-solasonine also increased significantly with increasing salinity. The present study is the first to through some light on the medicinal quality of S. villosum that would be quite helpful for production of secondary metabolites under salt-stressed conditions.

“…In laboratory and field conditions, thePistacia vera scions, grown on several Pistacia spp.rootstocks, can tolerate sodium chloride (NaCl) concentrations of up to 150 mM (Walker et al, 1987;Ferguson et al, 2002). In contrast, citrus, grape, and avocado are all characterized as relatively salinity sensitive tree crops, and grape and avocado can only tolerate up to 50 mM and 15 mM NaCl respectively (Bernstein et al, 2004;Mohammadkhani et al, 2016;Ahmad and Anjum, 2020).…”

Pistachio (Pistacia spp.) is a tree nut crop with relatively high salinity tolerance. Currently, limited information exists on its rootstock's cellular responses to salinity stress, especially in its roots. In this study, we investigated salinity tolerance at cellular level, in two pistachio rootstocks, Pistacia integerrima (PGI) and a hybrid, P. atlantica x P. integerrima (UCB1). Root tip sections were categorized across a developmental gradient according to their xylem development, and their sodium content and suberin deposition were analyzed with fluorescence microscopy. Our data demonstrated a correlation between vacuolar sequestration of sodium ions (Na+) and salinity tolerance in the UCB1 genotype. In addition, UCB1 displayed higher basal levels of suberization in both the exodermis and endodermis that increased further after salinity stress. Notably, the root region immediately distal to the region of secondary xylem initiation showed the highest amount of vacuolar Na+ sequestration, indicating a developmental regulation of this process. Our cumulative data demonstrate that salinity tolerance in pistachio rootstock species is associated with both vacuolar Na+ sequestration and suberin deposition at apoplastic barriers, and both are correlated with a root developmental gradient. These cellular characteristics are phenotypes that can be screened during the selection for salinity tolerant woody plant species.

“…In contrast, VvChS and VvPAL transcripts significantly increased only in the leaves of tolerant genotypes. 111 A total of 209 and 36 differentially expressed transcripts were identified in salt tolerant Kalamon and salt sensitive Chondrolia Chalkidikis olive cultivars in response to NaCl stress. In Kalamon, all the transcripts were significantly down regulated in the post-stress period.…”

Recent agriculture adaption regarding climate change

Food and nutritional security of a burgeoning global population in face of unabated land degradation, depletion of fresh water and prime croplands, and climate change impacts remains a challenge. Salinization of agricultural lands caused by the natural and anthropogenic factors a severe obstacles to realizing sustainable agricultural production. Majority of the fruit crops are highly susceptible to salinity and related problems like water logging. Use of salt tolerant scion and rootstock cultivars is seen as a viable means of lessening the salt induced damages. Nonetheless, development and commercial release of salt tolerant cultivars in fruit crops has progressed rather slowly. Moreover, salt tolerance of most of the currently available cultivars breaks down when root zone salinity exceeds the critical threshold. This has led to a departure from conventional screening trials to molecular and genomics tools to broaden the understanding of salt stress regulation at the gene, protein and metabolite levels. The ultimate aim is to introgress such genes into established cultivars in a manner that is cost efficient and safe from human and environmental health perspectives.
