“…Possibly, this increase in proline content helps alleviate the salt stress of the plants (Parida and Das 2005;Lima-Costa et al 2010;Upadhyay et al 2012;Rady et al 2016;Ferreira et al 2018;Chakdar et al 2019). The activities of certain antioxidative enzymes, such as peroxidase, are induced in plants to defend themselves against the reactive oxygen species (Parida and Das 2005;Gao et al 2008;Numan et al 2018), as seen in the present study (Fig.…”

Aim: This study aimed to screen halotolerant Bacillus strains able to promote growth and protect tomato plants against salt stress and Fusarium wilt (Fusarium oxysporum f. sp. lycopersici). Methods and Results: We evaluated some halotolerant strains of Bacillus spp. (Bacillus velezensis (AP-3) and Bacillus spp. (AP-6, AP-85 and AP-100)) to promote growth of tomato plants grown under salinity stress conditions and to protect them against Fusarium wilt disease. Such strains had been previously selected among 154 bacterial strains through biochemical tests (siderophores and indoleacetic acid productions, cellulase and catalase activity, nitrogen fixation and phosphate solubilization) in the presence of 100-mmol l À1 NaCl. Besides the above-mentioned strains, B. subtilis QST-713 (Serenade TM ) was also evaluated. Compared to control plants, aboveground dry weight increased in plants inoculated with AP-6, AP-85, AP-3, AP-100 and QST-713 strains developed in the absence of salt stress. The same tendency occurred for root dry weight; however, AP-3 strain was more effective, promoting an increase of 163%, when compared to control. Chlorophyll index and height increased >40 and 53%, respectively, for all Bacillus strains. Saline stress reduced plant growth regardless of the presence of Bacillus. Height, stem diameter, and aboveground and root dry weights increased in plants treated with Bacillus strains grown under saline conditions when compared to control. Bacillus velezensis AP-3 reduced the severity of Fusarium wilt in tomato by 50% when compared to control. Conclusion: Halotolerant Bacillus strains controlled tomato Fusarium wilt, increased growth as well as tolerance to salt stress. Significance and Impact of the Study: We demonstrated the efficacy of halotolerant Bacillus strains to control Fusarium wilt and improve tomato growth. We also demonstrated that these Bacillus strains protect tomato plants against salt stress. Bacillus can be used in an eco-friendly way because they are considered Generally Recognized As Safe.

“…Most studies have been tested foliar spraying of proline on field crops and vegetable crops such as common beans 9 , 40 mustard 41 , barley 42 , Aloe vera 43 , rice 44 , onion 20 and pea plant 45 . Lima-Costa 46 found that, exogenous proline at 5 mM improved vegetative growth of citrus plants under 100 mM NaCl. Proline application for Simmondsia chinensis at 20 mM significantly increased N, K and significantly decreased Cl and Na under salt stress conditions 47 .…”

Maximizing food production through integrated management of vegetative and root growth is a major challenge to food security and sustainability in the face of population growth, salinity stress conditions and climatic changes specially in arid and semi-arid regions. This study was conducted to evaluate the effect of foliar application with proline (Pro) at 5 mM, calcium (Ca) at 1.5% or control supplemented with soil application of humic acid (Hc) at 0, 15 g/tree on the nutrition status, osmoregulatory mechanisms and productivity of ‘Wonderful’ pomegranate trees growing under salt stress conditions. Soil and foliar treatments were applied three times: at flowering stage (April), 2 months after fruit set (June) and at fruit maturity (August). Individual application of either Hc or Pro or Ca alleviated the adverse effects of salt stress. Moreover, supplemented soil application of Hc with Pro or Ca as foliar application increased significantly leaf Pro, total carbohydrates, N, P, Ca and K contents, as well as K/Na and Ca/Na ratio. While it significantly decreased leaf Na and Cl concentration. Furthermore, supplemented application of Hc resulted in the highest decrease in leaf Na and Cl concentrations by 94.59%, 44.79% when combined with Pro and by 51.35%, 31.28%, when combined with Ca. In addition, Hc treatment led to the highest mean fruit yield by 139.56% and 90.73%, respectively as mean of both seasons for Pro and Ca treatments, respectively. The results suggest that, exogenous Pro and Ca supplemented with Hc can mitigate salt stress in ‘Wonderful’ pomegranate through enhancing osmoprotectants accumulaton.

“…36 Application of exogenous proline (5 mM) considerably minimized the salt damage in salt-sensitive Citrus sinensis 'Valencia late' cell line exposed to 100 mM NaCl. 37 Mannitol seems to be a potential osmoregulator in leaf mesophyll in salt stressed olive plants where increase in leaf mannitol concentration shows a positive correlation with the increasing root zone salinity. 38 Salt treated (0-75 mM NaCl) Mazzetto almond scions grafted on Garnem rootstock had higher proline, soluble sugar, K + and Ca 2+ concentrations but lower Na + compared to Mazzeto grafted on GF677.…”

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.

Alleviation of Salt Stress Using Exogenous Proline on a Citrus Cell Line

Abstract: Salinity constitutes an important abiotic problem since ancient times, worldwide, for it leads to a decrease in productivity of crops with agronomic value. Under salt stress conditions, plant cells develop strategies to cope with Na + and Cl
