Influence of Amino Acids Mixture Application on Some Biochemical Aspects, Antioxidant Enzymes and Endogenous Polyamines of Vicia faba Plant Grown under Seawater Salinity Stress

Abstract

able agriculture in arid and semiarid regions. In addition, it opens up new research lines aimed at obtaining maximum benefit from the amino acids under salinity or other osmotic stress conditions.

Improved Salinity Tolerance by Phosphorus Fertilizer in Two Phaseolus vulgaris Recombinant Inbred Lines Contrasting in Their P‐Efficiency

“…); reduced protein synthesis and enzymatic activity (Liang et al. , Sadak and Abdelhamid ); nutritional imbalance (lowering N, P, K + , Ca 2+ unbalanced carbon metabolism) (Hu et al. , Abdelhamid et al.…”

Amelioration of salinity tolerance in cowpea plants by seed treatment with methyl jasmonate

“…In this study, total soluble sugars contents in cowpea leaves were increased by salt stress. Accumulation of soluble sugars under salt stress was observed by Sadak and Abdelhamid (2015) on faba bean and Azooz et al (2015) on okra. Cowpea seeds soaked with MeJA revealed higher total soluble sugars content than the non-treated seeds under salinity conditions.…”

“…Proline is the most important amino acid occurs in plants which accumulate in larger amounts under environmental stresses such as salinity. Proline protects membranes, enzymes and proteins, acts as osmolyte, nitrogen storage compound and ROS scavenger, buffering cytosolic pH, balances redox status of the cell, activates specific gene expression and signaling molecule to modulate mitochondrial functions, and also reduces Na + and Cl -accumulation (Singh et al, 2015;Sadak and Abdelhamid, 2015). Present findings were in line with those observed in almond (Amiri et al, 2016), wheat (Kausar et al, 2013), rice (Revathi and Arumugam Pillai), faba bean (Sadak and Abdelhamid, 2015) and mung bean (Hozayn et al, 2013) under salt stress.…”

“…Adverse effects of salt stress are ascribed to osmotic stress, ion toxicity and production of ROS (Singh et al, 2015;Gupta and Huang, 2014). These effects cause various physiological, biochemical and agronomic changes, such as oxidative stress (Kausar et al, 2013;Sadak and Abdelhamid, 2015), internal nutrient imbalance Tartoura et al, 2014), alteration water status (Wang et al, 2015;Li et al, 2015), reduction pigments content, gas exchange and photosynthesis (Aftab et al, 2011;Wang et al, 2015), inhibition in seed germination (Nasri et al, 2016;Kusvuran, 2015) and reduction of growth and loss in productivity (Tartoura et al, 2014;Kausar et al, 2013). In order to cope up with salt stress plants undergo various biochemical and physiological changes, including: biosynthesis of compatible solutes and osmoprotectants, ions homeostasis and compartmentalization, control of ion uptake and transport, selective accumulation or exclusion of ions, generation of nitric oxide, changing hormone levels and enhancing antioxidative systems (Gupta and Huang, 2014).…”

La Homeopatía incrementa la tolerancia al estrés por NaCl en plantas de frijol común (Phaseolus vulgaris L.) variedad Quivicán

“…Approximately 800 million ha of land, equivalent to more than 6% of the total global area of the planet are affected by soil salinity (FAO, 2008). The excess of salts limits plant growth and productivity (Khan and Panda, 2007) and inhibits growth in a very important manner because it affects essential metabolic processes, such as photosynthesis (El-Hendawy et al, 2005), protein synthesis and enzymatic activity (Liang et al, 2005;Sadak and Abdelhamid, 2015). Additionally, salinity affects transpiration, cell las plantas sometidas a estrés salino alcanzó el mayor valor con NaM-7CH, observándose un incremento mayor al 50% en TF con respecto al tratamiento control (AD).…”
