“…The enzyme CAT removes H 2 O 2 by breaking it down to form H 2 O and oxygen, and oxidizes H donors with the consumption of peroxide. We have demonstrated that CAT activity increased in all the resistant, one susceptible, and one semiresistant chickpea cultivar / advanced line under cold stress, which is a similar finding to some other researchers [25][26][27]. Cicer arietinum 'Saral' , the most novel genotype studied, appropriately reacted to MS and showed high CAT activity, but with intensification of cold stress, the activity of this enzyme decreased.…”

Abiotic stresses such as cold, heat, and drought are the main causes of universal crop losses. Plants have generated adaptive responses which prevent them from oxidative damage caused by environmental stresses. The present research aimed to evaluate the effect of cold stress on lipid peroxidation and antioxidant enzyme activity in the leaves of eight cultivars / advanced lines of chickpea (<em>Cicer arietinum</em> L.). Three-week-old plantlets were subjected to cold stress (0°C) for 24 or 48 hours. Selected antioxidant enzyme activity and oxidative status of chickpea plantlets under cold stress were determined. In most genotypes, catalase and ascorbate peroxidase activities were increased and guaiacol peroxidase activity decreased under stress conditions but the activity of superoxide dismutase remained almost constant. Based on its ranking, <em>Cicer arietinum</em> ‘Saral’, a newly released cold-resistant Iranian chickpea cultivar, had the strongest, and FLIP 05-77C had the weakest antioxidative defense system under low temperature stress.

“…There was a significantly higher ion leakage, higher percentage of water loss from the excised leaf, and relatively low weight of the saturated leaf of the VIGS plants compared to their wild types under drought and salt stress conditions. Reduction in SLW, increased ion leakage, and percentage water loss from the excised leaf are indications that the VIGS plants suffered intensive oxidative stress, and thus lost the ability to tolerate the effects of drought and salinity stress [71]. Moreover, oxidant and antioxidant enzyme assays showed that the VIGS plants registered higher levels of oxidant enzymes and a significant reduction of the antioxidant enzymes under salt and drought stress conditions compared to their wild types.…”

We identified 672, 374, and 379 CYPs proteins encoded by the CYPs genes in Gossypium hirsutum, Gossypium raimondii, and Gossypium arboreum, respectively. The genes were found to be distributed in all 26 chromosomes of the tetraploid cotton, with chrA05, chrA12, and their homeolog chromosomes harboring the highest number of genes. The physiochemical properties of the proteins encoded by the CYP450 genes varied in terms of their protein lengths, molecular weight, isoelectric points (pI), and even grand hydropathy values (GRAVY). However, over 99% of the cotton proteins had GRAVY values below 0, which indicated that the majority of the proteins encoded by the CYP450 genes were hydrophilic in nature, a common property of proteins encoded by stress-responsive genes. Moreover, through the RNA interference (RNAi) technique, the expression levels of Gh_D07G1197 and Gh_A13G2057 were suppressed, and the silenced plants showed a higher concentration of hydrogen peroxide (H2O2) with a significant reduction in the concentration levels of glutathione (GSH), ascorbate peroxidase (APX), and proline compared to the wild types under drought and salt stress conditions. Furthermore, the stress-responsive genes 1-Pyrroline–5-Carboxylate Synthetase (GhP5CS), superoxide dismutase (GhSOD), and myeloblastosis (GhMYB) were downregulated in VIGS plants, but showed upregulation in the leaf tissues of the wild types under drought and salt stress conditions. In addition, CYP450-silenced cotton plants exhibited a high level of oxidative injury due to high levels of oxidant enzymes, in addition to negative effects on CMS, ELWL, RLWC, and chlorophyll content The results provide the basic foundation for future exploration of the proteins encoded by the CYP450 genes in order to understand the physiological and biochemical mechanisms in enhancing drought and salt stress tolerance in plants.

Water-deficit stress is the most important environmental factors limiting plant growth, and production. Nano-titanium dioxide (nano anataseTiO 2 ) can have various profound effects on the crop physiological, biochemical and morphological characteristics. In the present research, the influences of different concentrations ofTiO 2 nanoparticles (NPs) (0, 10 and 40 ppm) and water-deficit stress on Dragonhead (Dracocephalum moldavica L.) were investigated in a factorial experiment based on randomized complete block design with three replications. Results showed that under normal irrigation, foliar application of 10 ppm TiO 2 NPs increased plant shoot dry mass and essential oils content. Under water-deficit stress condition, plants treated with 10 ppm TiO 2 NPs had more proline and much less H 2 O 2 and malondialdehyde content as compared to untreated plants. Therefore, it can be concluded that proper concentration of TiO 2 NPs probably can be used as an exogenous stimuli for improvement of shoot growth and essential oil content in plants. Furthermore, water-deficit stress-induced damages such as oxidative stress and membrane damage can be ameliorated by foliar application of TiO 2 NPs at appropriate concentrations. Sušni stres je eden izmed najpomembnejših okoljskih dejavnikov, ki omejujejo rast in produktivnost rastlin. Uporaba nano delcev titanovega dioksida (TiO 2 nano anataza) ima lahko velike učinke na fiziološke, biokemične in morfološke lastnosti gojenih rastlin. V tej raziskavi je bil v naključnem faktorskem bločnem poskusu preučevan vpliv različnih koncentracij nano delcev TiO 2 (0, 10 in 40 ppm) in sušnega stresa na moldavsko kačjeglavko (Dracocephalum moldavica L.) v treh ponovitvah. Rezultati so pokazali, da sta se suha masa in vsebnost eteričnih olj povečali pri normalnem namakanju in listnem dodajanju 10 ppm TiO 2 nano delcev. V razmerah sušnega stresa so vsebovale rastline, ki so bile tretirane z 10 ppm TiO 2 več prolina in mnogo manj H 2 O 2 in malonildialdehida v primerjavi z netretiranimi rastlinami. Na osnovi tega bi lahko zaključili, da bi z uporabo primerne koncentracije nano delcev TiO 2 kot zunanjega stimulanta, lahko izboljšali rast poganjkov in vsebnost eteričnih olj pri tej rastlini. Poškodbe kot sta oksidativni stres in poškodovanost membran, ki nastanejo zaradi sušnega stresa, bi lahko ublažili s foliarno aplikacijo primerne koncentracije nanodelcev TiO 2 .
