“…Moreover, the exogenous application of phytohormones found a promising practical strategy to deal with salt stress. The exogenous application of phytohormones exhibited a rapid increase in plant growth under stress conditions [17,[23][24][25]. Therefore, understanding the function of specific phytohormones will provide essential insights of plant mechanism to adapt salinity tolerance.…”

Plants undergo a wide range of morphological, cellular, anatomical, and physiological changes in response to salinity stress. However, plants produce some signaling molecules, usually known as phytohormones, to combat stress conditions. Salinity tolerance is a complex mechanism, whereas phytohormones have a central role in it. Phytohormone-mediated plant responses improve nutrient uptake, the source-sink relationship, and plant growth and development. Phytohormones triggers the specific gene expressions which are responsible for the modification of various plant mechanisms under salinity stress. This review summarized the most recent research findings about plant responses to salinity stress at physiological and molecular levels and discussed the probable function of several (abscisic acid, indole acetic acid, cytokinins, gibberellic acid, salicylic acid, brassinosteroids, ethylene, and triazoles) phytohormones and their interaction in modulating salinity stress. Further, the understanding of specific genes involved in phytohormonal regulation toward salinity tolerance is a key to developing breeding and transgenic approaches for meeting food demand under sustainable crop production.

“…Polyamines (PAs) are a class of biogenic amines with multiple vital roles in the growth of plants. Three ubiquitous amines, viz., spermidine, spermine, and putrescine, are the most frequent PAs in plants and are widely used as plant growth regulators (PGRs) 15 .…”

The effects of arbuscular mycorrhizae fungi (AMF), putrescine (Put), and their combination on essential oil (EO) content, chlorophyll (Chl), carotenoid and EO chemical compounds of cumin (Cuminum cyminum L.) were studied under optimal and drought stress conditions. The foliar application of Put or inoculation with AMF significantly (P ˂ 0.05) increased seed yield, EO content, EO yield, Chl a, Chl b, total Chl, and carotenoid. Moreover, AMF or Put application increased cuminaldehyde, limone, and β-Pinene and decreased γ-Terpinene, o-Cymene, and linalool concentration in cumin plants compared to non-treated plants in both optimal and drought stress conditions. However, the highest EO content, EO yield, Chl a, Chl b, total Chl, carotenoid, and major EO chemical components were obtained when AMF and Put were used together under optimal and drought stress conditions. This study showed that Put and AMF can be co-applied to the cumin plant to significantly improve drought tolerance in field conditions greatly.

Putrescine (Put), gibberellic acid (GA3), and salicylic acid (SA) are involved in improving fruit growth and development. This is the first study investigating the effect of 1 mM Put, 100 mg L-1 GA3, and 100 mg L-1 SA on Phoenix dactylifera, cv. Zaghloul fruits. The experiment was conducted in a completely randomized block design during two successive seasons and five treatments [control (distilled water spray), Put, Put + GA3, Put + SA, and Put + GA3 + SA] were sprayed at the Hababouk (cell division) stage and Kimri [unripe green (cell elongation)] stage. Our results showed that all treatments significantly improved the yield and quality of ‘Zaghloul’ fruit by increasing the dry matter, crude fiber, ash, total soluble solids, (reducing, non-reducing, and total soluble) sugars, carbohydrate, protein, nitrogen, phosphorus, potassium, calcium, magnesium, sodium, zinc, iron, and manganese content as well as the peroxidase and catalase activity. Compared with the control treatment, exogenous applications also enhanced the amino acid (glutamic acid, aspartic acid, proline, glycine, alanine, arginine, cysteine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, serine, threonine, tyrosine, valine) acquisition and phytohormone (indole-3-acetic acid, cytokinins, GA3, SA) content, while decreasing the percentage of moisture, total acidity, total phenols, and tannins. The novel evidence indicates that among all treatments, application of diamine (Put), in combination with phytohormones (GA3 and SA), has the greatest effect on improving ‘Zaghloul’ fruit yield by up-regulating the nutrient acquisition, sugar accumulation, amino acid profile, antioxidant response, and phytohormone performance. These findings support the use of Put in conjunction with GA3 and SA to improve fruit yield and quality.
