“…The photosynthetic rate was increased by R. leguminosarum strain induced by the inducers NA and the combined MJ+NA at 0.6 dS m -1 treatment but the effect was reversed using MJ. This result confirmed the findings of Tsonev et al 20) and other researches [26][27] who reported that the use of MJ generally decreased photosynthesis, plant height and leaf area under non-salinity stress. At 3.0 dS m -1 , the photosynthetic rate increase over the control was 7.6 and 12.3%, respectively while at 6.0 dS m -1 salinity, the increase was 15.4 and 0.5%, respectively.…”

“…JA and MJ, a volatile derivative of JA, are also involved in salinity stress. For example, the application of JA and MJ diminished the inhibitory effect of high salinity on growth and photosynthesis of barley 20) . Little is known about nodulation, photosynthesis and growth of pea medicinal plants grown under salinity stress conditions, when inoculated with rhizobia pre-incubated with NA and MJ inducers.…”

The legume-rhizobia symbiosis is an important source of plant growth and nitrogen fixation for many agricultural systems. This study was conducted to investigate the effects of salinity stress on nitrogen fixation and growth of pea (Pisum sativum L.), which has antimutagenic activities against chemical mutagen, inoculated with R. leguminosarum bv. viciae cultured with additional plant-to-rhizobia signal compounds, naringenin (NA,15 uM), methyl-jasmonate (MJ, 50 uM) or both, under greenhouse conditions. Three salinity levels (0.6, 3.0 and 6.0 dS m -1 ) were imposed at 3 days after transplanting and maintained through daily irrigations. Addition of signal compounds under non-stress and stress conditions increased dry weight, nodule numbers, leaf area and leaf greenness. The inducers increased photosynthetic rate under non-stress and stress conditions, by approximately 5-20% when compared to that of the non-induced control treatment. Under stress conditions, proline content was less in plants treated with plant-to-bacteria signals than the control, but phenol content was significantly increased, compared to that of the control. The study suggested that pre-incubation of bacterial cells with plant-to-bacteria signals could enhance pea growth, photosynthesis, nitrogen fixation and biomass under salinity stress conditions.

“…In spite of this beneficial effect, ABA could have a limited effect since it could form conjugates and/or be degraded rapidly (Cutler and Krochko, 1999). JA has also been found to facilitate acclimation of crops such as barley and strawberry to saline conditions (Tsonev et al, 1998).…”

Citrus yield and growth are deeply affected by salinity. In the present work we have studied the effectiveness of differentplant growth regulators such as abscisic acid, jasmonic acid and 8-methylene methyl abscissate in protectingcitrus from salt-induced damage. Plants of Salustiana cultivar grafted onto Carrizo citrange were used for this purpose.Plants were watered with 100 mM NaCl and leaf abscission, ethylene production, chloride accumulation and net photosyntheticrate were measured. Non-treated plants showed a dramatic drop in photosynthetic activity in response tosalinity, an increase in leaf ethylene production and a high abscission rate as a result of a massive leaf chloride accumulation.Plants treated with jasmonic acid or 8-methylene methyl abscisate did not show any physiological changein response to salt stress. However, plants treated with abscisic acid showed a high reduction in the parameters considered.These results suggest that abscisic acid plays a role in modifying citrus physiological behaviour in responseto salinity and could be helpful in their acclimation to saline conditions

“…The intensive research in stress physiology revealed its role as a signaling or stress-modulating molecule against various environmental stresses. Currently, JA is receiving much attention due to its multifunctional defense properties in plants against several abiotic stresses, including salinity (Tsonev et al, 1998), drought (Creelman and Mullet, 1997), and herbicides (Kaya and Doganlar, 2016). However, studies of its role in plants under heavy metal stress are few (Chen et al, 2014), especially regarding the interactive effects of Cd and JA application on rapeseed oil.…”

Abstract:The well-known detrimental effects of cadmium (Cd) on plants are chloroplast destruction, photosynthetic pigment inhibition, imbalance of essential plant nutrients, and membrane damage. Jasmonic acid (JA) is an alleviator against different stresses such as salinity and drought. However, the functional attributes of JA in plants such as the interactive effects of JA application and Cd on rapeseed in response to heavy metal stress remain unclear. JA at 50 µmol/L was observed in literature to have senescence effects in plants. In the present study, 25 µmol/L JA is observed to be a "stress ameliorating molecule" by improving the tolerance of rapeseed plants to Cd toxicity. JA reduces the Cd uptake in the leaves, thereby reducing membrane damage and malondialdehyde content and increasing the essential nutrient uptake. Furthermore, JA shields the chloroplast against the damaging effects of Cd, thereby increasing gas exchange and photosynthetic pigments. Moreover, JA modulates the antioxidant enzyme activity to strengthen the internal defense system. Our results demonstrate the function of JA in alleviating Cd toxicity and its underlying mechanism. Moreover, JA attenuates the damage of Cd to plants. This study enriches our knowledge regarding the use of and protection provided by JA in Cd stress.
