“…When evaluating the effect of salt stress on tomato yield, it can be seen that salt stress will significantly reduce the size of the fruit diameter and the weight of tomato stems and leaves. The single fruit weight of tomato decreased significantly with the increase of irrigation salinity in this experiment, which was the same as the studies by Cao et al [27] Salt has an inhibitory effect on many physiological and biochemical processes, such as changing the hormone secretion processes, inhibiting the height of seed germination plants, changing the development time points, and shortening the growth stage [28] ; inhibiting the differentiation and growth of plant tissues and organs; reducing leaf area and reducing photosynthetic intensity, resulting in reduced yield [29,30] .…”

The objective of this study was to explore the effects of different degrees of water and salt stress on the actual water consumption and soil salt accumulation of tomatoes and the salt tolerance characteristics of tomatoes under brackish water combined with regulated deficit irrigation mode. The greenhouse pot experiment was used to set three influencing factors, the irrigation water salinity S1 was 1.1 g/L (local shallow groundwater), S2 was 2.0 g/L, and S3 was 4.0 g/L, respectively, and different degrees of water deficit (W1 ranged from 65%-75% Field Capacity (FC), W2 ranged from 55%-65% FC, W3 ranged from 45%-55% FC) and seedling stage (T1), blossoming and bearing fruits stage (T2) and mature picking stage (T3). The response of fresh fruit weight, stems and leaves weight, yield and water use efficiency of tomato under water and salt stress were monitored and analyzed. The results showed the coordinated regulation of water and salt can significantly reduce the electrical conductivity of the 0-30 cm soil of the tomato root system. The higher the salinity of irrigation water, the better the salt control effects of the coordinated regulation of water and salt; the coordinated regulation of water and salt at different growth stages had significant effects on the weight of fresh tomato fruits, the weight of stems and leaves and the yield. The salinity of irrigation water was in inverse proportion to the yield of tomatoes; In S1 treatment irrigation (irrigation water salinity was 1.1 g/L) under the mildly regulated deficit in the seedling stage (irrigation water was 55%-65% of the field water capacity) can effectively reduce the irrigation water volume during the whole growth stage while ensuring that there was no significant reduction in yield. The research results provided a scientific and reliable theoretical basis for the increase of local tomato production, the improvement of water use efficiency and the formulation of suitable irrigation patterns.

“…In woodland sage ( Salvia nemorosa ) exposed to environmental salinity, SL treatments (0.1, 0.2, 0.3, and 0.4 μM) reduced the harmful effects of salinity by increasing proline accumulation and decreasing POD, CAT, SOD, and DR activities ( Sharifi and Bidabadi, 2020 ). Exogenous application of SLs also improved plant growth rates, particularly at 0.4 μM SL.…”

Plant hormones and neurotransmitter interactions mediate antioxidant defenses under induced oxidative stress in plants

Due to global climate change, abiotic stresses are affecting plant growth, productivity, and the quality of cultivated crops. Stressful conditions disrupt physiological activities and suppress defensive mechanisms, resulting in stress-sensitive plants. Consequently, plants implement various endogenous strategies, including plant hormone biosynthesis (e.g., abscisic acid, jasmonic acid, salicylic acid, brassinosteroids, indole-3-acetic acid, cytokinins, ethylene, gibberellic acid, and strigolactones) to withstand stress conditions. Combined or single abiotic stress disrupts the normal transportation of solutes, causes electron leakage, and triggers reactive oxygen species (ROS) production, creating oxidative stress in plants. Several enzymatic and non-enzymatic defense systems marshal a plant’s antioxidant defenses. While stress responses and the protective role of the antioxidant defense system have been well-documented in recent investigations, the interrelationships among plant hormones, plant neurotransmitters (NTs, such as serotonin, melatonin, dopamine, acetylcholine, and γ-aminobutyric acid), and antioxidant defenses are not well explained. Thus, this review discusses recent advances in plant hormones, transgenic and metabolic developments, and the potential interaction of plant hormones with NTs in plant stress response and tolerance mechanisms. Furthermore, we discuss current challenges and future directions (transgenic breeding and genome editing) for metabolic improvement in plants using modern molecular tools. The interaction of plant hormones and NTs involved in regulating antioxidant defense systems, molecular hormone networks, and abiotic-induced oxidative stress tolerance in plants are also discussed.

“…SL-deficient ( max3 and max4 ) and SL-signaling ( max2 ) mutants showed hypersensitivity to salinity in Arabidopsis thaliana and Malus domestica during the germination and vegetative phase. Moreover, applying SLs in salt-exposed rice [ 99 ] and Salvia nemorosa [ 100 ] improved ROS scavenging responses, such as reduced H 2 O 2 and MDA content and lesser cellular damage. The findings of Ren et al [ 101 ] state that a combination of salt stress, ABA, and H 2 O 2 stimulates SL-biosynthesis genes, including CCD7 , CCD8 (in root) as well as MAX2 (in the shoot) in AMF-associated Sesbania cannabina .…”

Improving plant resilience to changing environmental conditions is the primary focus of today's scientific research globally. It is essential to find various strategies for the better survival of plants with higher resistance potential to climate change. Strigolactones (SLs) are multifunctional β-carotene derivative molecules that determine a range of plant growth and development aspects, such as root architecture, shoot branching, chlorophyll synthesis, and senescence. SLs facilitate strong defense responses against drought, salinity, heavy metal, nutrient starvation, and heat stress. The SLs trigger other hormonal-responsive pathways and determine plant resilience against stressful environments. This review focuses on the mechanisms regulated by SLs and interaction with other plant hormones to regulate plant developmental processes and SLs’ influence on the mitigation of plant damage under abiotic stresses. A better understanding of the signaling and perception of SLs may lead to the path for the sustainability of plants in the changing environmental scenario. The SLs may be considered as an opening door toward sustainable agriculture.
