Lattice henbane (Hyoscyamus reticulatus L.) is an herbaceous, biennial plant belonging to Solanaceae family. H. reticulatus hairy roots were established from two-week-old leaves infected by A7 strain of Agrobacterium rhizogenes on solid Murashige and Skoog (MS) medium. In this study, abiotic elicitors including; Sodium silicate (Na2SiO3) with different concentrations (0, 1, 5 and 7 mM) and silv...

Salicylic acid (SA) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. The physiological mechanism of exogenous SA to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mM SA and then held at 25◦C up to 12 days. ...

The dyes used in the production of textile industry are toxic substances that resistant to biological treatment. Most them have highly complex polymer structures. Salicylic acid (SA) is an important hormone produced by plants provides tolerance many biotic and abiotic stress factors. Duckweed (L. minor L.) free floating plants. These been laboratory toxicological studies researchers for reasons...

Transgenic Arabidopsis plants expressing a potato D200 gene encoding hypothetical protein were subjected to salinity stress and assessed for their tolerance. The lines exhibited increased chlorophyll content, improved stomatal conductance, less electrolyte leakage, lower accumulation of malondialdehyde (MDA), higher amount proline compared the wild type (WT) under stress. expression analysis re...

Understanding the salinity stress mechanisms is essential for crop improvement and sustainable agriculture. Salinity prepotent abiotic compared with other stresses that decrease growth development, reducing production creating food security-related threats. Therefore, input of metal oxide nanoparticles (NPs) such as zinc (ZnO-NPs) can improve salt tolerance in plants, especially early stage gro...

The role of oxidative stress management was evaluated in two maize (Zea mays L.) genotypes - Parkash (drought-resistant) and Paras (drought-sensitive), subjected to drought stress during reproductive stage. Alterations in their antioxidant pools - glutathione (GSH) and ascorbic acid (AsA) combined with activities of enzymes glutathione reductase (GR), ascorbate peroxidase (APX), peroxidase (POX...

Pitaya fruits have high senescence rates throughout their postharvest storage period. Additionally, studies confirmed that melatonin plays a regulatory role in plant senescence. However, the involvement of remains unclear. In this study, two cultivars pitaya fruit, ‘Zihonglong’ and ‘Jinghonglong’, were treated with then evaluated for characteristics while 10 days. The results showed treatment d...

Aluminum toxicity is one of the most deleterious factors for plant growth in acidic soils because over 50% of the world’s potentially arable lands are acidic. In recent years, considerable research has been conducted to understand the mechanisms of Al toxicity and tolerance in plants. This paper reviews the effects of different concentration of Al on plant shoot, root physiological parameters s...

A large number of studies have shown the existence of cross-tolerance in plants, but the exact physiological and biochemical mechanism(s) is poorly understood. In this study, heat-shock (42 °C, 5 h) induced salinity and drought tolerance and possible involvement of antioxidative and glyoxalase systems were investigated in mustard (Brassica campestris L.) seedlings. Seven-day-old seedlings were ...
