“…Hala (2005) also reported that addition of nicotinamide or tryptophan decreased Na + and Clcontent and increased K + and Ca 2+ in the wheat shoots. These results are in line with previously published report on fenugreek (Babar et al, 2014), wheat (Iqbal and Ashraf, 2013) and barley (El-Tayeb, 2005) that foliar applied salicylic acid and tryptophan enhanced vegetative growth. Exposure of wheat seedling to SA or tryptophan caused a remarkable increase in yield and yield attributes compared to plants that were not treated with SA or L-tryptophan.…”

In recent decades effective regulatory role of phytohormones in plants in response to salinity has received considerable attention. However, their role acting in combination with gypsum still remain elusive. That is why, this two-year study was conducted to assess the effects of foliar application of salicylic acid and L-tryptophan with and without gypsum on wheat crop in a moderately salt affected soil with ECe: 4.71 dS m-1 , pHs: 9.18 and SAR: 31.82. Treatments detail is as under:-(A). Amendments 1: gypsum @ 50% GR, 2: without gypsum, (B).

“…Exogenous phytohormone application has also been proposed as a useful tactic to address various abiotic stresses, such salinity, drought, etc. ( Iqbal et al., 2006 ), and also associated with several studies in reducing the negative impacts of abiotic stressors ( Sharma et al., 2013 ; Iqbal and Ashraf 2013a , b ; Amjad et al., 2014 ). The primary location for auxin production is in the apical meristem of shoots, immature leaves, and seeds.…”

In recent times, the demand for food and feed for the ever-increasing population has achieved unparalleled importance, which cannot afford crop yield loss. Now-a-days, the unpleasant situation of abiotic stress triggers crop improvement by affecting the different metabolic pathways of yield and quality advances worldwide. Abiotic stress like drought, salinity, cold, heat, flood, etc. in plants diverts the energy required for growth to prevent the plant from shock and maintain regular homeostasis. Hence, the plant yield is drastically reduced as the energy is utilized for overcoming the stress in plants. The application of phytohormones like the classical auxins, cytokinins, ethylene, and gibberellins, as well as more recent members including brassinosteroids, jasmonic acids, etc., along with both macro and micronutrients, have enhanced significant attention in creating key benefits such as reduction of ionic toxicity, improving oxidative stress, maintaining water-related balance, and gaseous exchange modification during abiotic stress conditions. Majority of phytohormones maintain homeostasis inside the cell by detoxifying the ROS and enhancing the antioxidant enzyme activities which can enhance tolerance in plants. At the molecular level, phytohormones activate stress signaling pathways or genes regulated by abscisic acid (ABA), salicylic acid (SA), Jasmonic acid (JA), and ethylene. The various stresses primarily cause nutrient deficiency and reduce the nutrient uptake of plants. The application of plant nutrients like N, K, Ca, and Mg are also involved in ROS scavenging activities through elevating antioxidants properties and finally decreasing cell membrane leakage and increasing the photosynthetic ability by resynthesizing the chlorophyll pigment. This present review highlighted the alteration of metabolic activities caused by abiotic stress in various crops, the changes of vital functions through the application of exogenous phytohormones and nutrition, as well as their interaction.

“…Previous study showed significant reduction of IAA level of rice after exposure to salinity stress over for 5 days (Nilsen and Orcutt, 1996). In addition, seed priming of salt-intolerant wheat cultivars with different sources of auxins (IAA, IBA and tryptophane) was diminished by salt stress (Iqbal and Ashraf, 2013). It was also reported that the high salinity reduced the phosphorus uptake of plant roots by sorption processes (Rojas-Tapias et al, 2012).…”

Salt‐tolerant plant growth‐promoting rhizobacteria (ST‐PGPR) are known as potential tools to improve rice salinity tolerance. In this study, we aimed to investigate the plant growth‐promoting rhizobacteria community richness of the paddy rice fields in Soc Trang and Ben Tre Provinces where were seriously affected by sea level rise. The salinity in the sampling sites ranged from 0.14‰ to 2.17‰ in November 2018, the rainy season. The microbial abundance of samples was evaluated by spreading the samples in tryptic soy agar (TSA) medium supplemented with various concentrations of NaCl. With the increase of salt concentration up to 10% NaCl, a total number of bacteria decreased for all the samples, ranging from 106 to 104 CFU/g, and bacterial colonies were not observed at 30% NaCl. Among a total of 48 salt-resisting bacteria isolated from the rice paddy field mud surrounding the rice root, 22 isolates were able to produce indole-3-acetic acid (IAA: phytohormone for the plant growth). Seventeen out of 48 isolates were able to grow in the medium without nitrogen or phosphor sources. Six isolates having high IAA producing activity, nitrogen fixation and phosphate solubilization were belonged to Bacillus (DT6, LT16, and LHT8), Halobacillus (DT8), Aeromonas (LHT1), and Klebsiella (LHT7) genera. All the sequences of the strains DT6, DT8, LT16, LHT1, LHT7, and LHT8 were registered in the GeneBank with the accession numbers MK335670, MK335671, MK335672, MK335673, MK335674, and MK335675, respectively.
