“…Proline accumulation in plants is related to water stress tolerance ( La et al ., 2019 ; Moreno-Galván et al ., 2020 ), and it is the most biochemical trait of drought tolerance ( Singh et al ., 2014 ). Lowering osmotic potential can help water uptake ( Rani et al ., 2022 ) and maintain cellular turgor ( Abid et al ., 2018 a ; Soni et al ., 2021 ). This is particularly important since metabolic processes appear to be more closely linked to cell turgor than leaf water potential ( Leuschner et al ., 2019 ; Soni et al ., 2021 ).…”

Local genetic resources could constitute a promising solution to overcome drought stress. Thus, eight (8) durum wheat landraces and one improved variety were assessed for drought tolerance in pots under controlled conditions. Three water treatments were tested: control (100% of the field capacity (FC)), medium (50% FC), and severe (25% FC) stress. The assessment was carried out at the seedling stage to mimic stress during crop set-up. Results showed that increased water stress led to a decrease in biomass and morpho-physiological parameters and an increase in antioxidant enzyme activities. Severe water stress decreased the chlorophyll fluorescence parameters, relative water content, and water potential of the investigated genotypes by 56.45%, 20.58%, 50.18%, and 139.4%, respectively. Besides, the phenolic compounds content increased by 169.2% compared to the control. Catalase (CAT) and Guaiacol Peroxidase (GPX) activities increased at 17 days after treatment for most genotypes except Karim and Hmira. A principal component analysis showed that the most contributed drought tolerance traits were Chlorophyll fluorescence parameters, relative water content, and electrolyte conductivity. UPGMA clustering showed that the landraces Aouija, Biskri, and Hedhba exhibited a higher adaptive response to drought stress treatments indicating that water stress-adaptive traits are included in Tunisian landraces germplasm.

“…According to Liu et al (2020), AMF enhance drought tolerance by reducing the osmotic potential, and the levels of soluble sugars and proline in the leaves of AMF-inoculated tobacco plants were higher than those of noninoculated plants. Rani et al (2023) reported that AMF-inoculated plants exhibit higher accumulation of compatible solutions, thus contributing to the maintenance of turgor pressure and facilitating water absorption in wheat plants. The plants effectively counteract drought stress by enhancing leaf water potential through the accumulation of compatible solutes, which improve the osmoregulation capacity of plants, thus allowing them to maintain optimal cellular function under water-deficient conditions (Reyhani Haghighi et al 2021).…”

Drought is a primary abiotic stressor that markedly impairs pepper growth and quality. This study aimed to investigate the effects of foliar applications of phytohormones, including salicylic acid (SA), jasmonic acid (JA), and root application of arbuscular mycorrhizal fungi (AMF), on severe and moderate drought stress of 38-day-old ‘Anemon F1’ pepper plants. The results showed that drought stress led to a considerable decrease in plant growth parameters, nutrient uptake, leaf water content, and chlorophyll content, and it increased leaf temperature, phenolic and flavonoid contents, and antioxidant enzyme activity. Nevertheless, the combined application of AMF with SA and JA demonstrated substantial synergistic effects, resulting in a notable improvement in the ability to alleviate the detrimental impacts of drought stress. Furthermore, the combined application of AMF and phytohormones exhibited a stronger effect on drought stress compared with the individual application of AMF or phytohormones alone. The application of AMF+SA and AMF+JA not only improves the availability of essential nutrients but also leads to an increase in fresh shoot weight, relative water content, leaf area, and chlorophyll and antioxidant capacity. Consequently, the combined application of SA and JA with mycorrhiza emerged as a promising treatment for enhancing pepper growth under drought-stress conditions. The positive results observed in pepper cultivation through the combined use of phytohormones and mycorrhizae in regions with limited water availability emphasize the importance of investigating the effectiveness of similar approaches in other agricultural crops.

“…Inoculation with PSB significantly reduced MDA concentration, an effect similar to that of AMF. Several studies have shown that MDA concentration in mycorrhizal plants is correlated with drought tolerance (Abbaspour et al, 2012;Rani et al, 2018). Rahimzadeh and Pirzad (2017b) showed that under water deficit MDA was significantly reduced in plants inoculated with both AMF and PSB.…”

Promoting growth and production of sunchoke (Helianthus tuberosus) by co-inoculation with phosphate solubilizing bacteria and arbuscular mycorrhizal fungi under drought

et al. 2022

Due to different functions of phosphate solubilizing bacteria (PSB) and arbuscular mycorrhizal fungi (AMF), their potential synergistic effects on enhancing plant growth and yield are worth investigating, especially under adverse conditions. This work focused on the isolation of PSB and characterization for their plant growth promoting properties under drought. The most efficient P solubilizing bacterium was isolated and identified as Burkholderia vietnamiensis strain KKUT8-1. Then, a factorial experiment on the performance of sunchoke (Helianthus tuberosus) was set up with four factors, viz., PSB (presence or absence of KKUT8-1), AMF (presence or absence of Rhizophagus aggregatus), rock phosphate (RP; added or not) and moisture (well-watered (WW) or drought (DS) conditions). Sunchoke performance was enhanced by the presence of AMF, whereas addition of PSB had a positive effect on SPAD values and inulin concentration. Drought reduced plant performance, while addition of RP reduced photosynthetic rate. There was little evidence for synergistic effects between PSB and AMF, except for SPAD values and inulin concentration. Plants that were co-inoculated with AMF and PSB had highest SPAD value, shoot diameter, leaf area, leaf number, chlorophyll concentration, plant biomass, tuber production, root growth and total soluble sugar concentration. Co-inoculated plants also had increased plant water status, reduced electrolyte leakage, and reduced malondialdehyde and proline concentration. Strain KKUT8-1 is the first strain of B. vietnamiensis capable of promoting growth and yield of sunchoke. Enhanced production of sunchoke by a combination of AMF and PSB was much better than the application of RP. Our finding offers an opportunity to develop combinations of biological inoculants for increasing the growth and production of sunchoke under drought in the future.
