“…The results described in this study indicate that there is important morphophysiological divergence between wild and cultivated S. multicaulis which is depend on cultivation conditions, STs and SMR especially. Although some plant species didn't showed morphophysiological changes (Qayyum et al., 2018) but, this research showed different results under cultivation conditions. Casas et al.…”

Depending on the physical environmental conditions, cultivation process can have significant effects on the wild plants' morphophysiological characteristics . Stachys multicaulis is an Iranian wild endemic medicinal plant species and its cultivation preformed under different Soil Textures (ST) and Soil Moisture Regimes (SMRs). Controlled pot culture conditions performed with light, moderate, heavy STs and a set of SMRs at 100% Field Capacity (FC), 70%FC and 30% FC. Plant cultivated in heavy STs had higher performance in all measured treats. Height of plant (HP), Calibrated Greenness (CG), Leaf Ratio (LR) and Angle (LA), aerial Moisture Content (MC) did not show a regular trend in comparison to the wild. Unlike the Density of Trichome (DT), Length of leave's Trichome (LT) showed a significant change under cultivation conditions (p < 0.01). Also, as a physiological response, Essential Oils Components (EOC), especially thymol and bicyclogermacrene decreased with decreasing soil MC for light ST and the lowest change were observed in heavy ST and 30%FC. Generally, cultivation reduced EOCs, but improved plant's morphological characteristics.

“…Under water deficit conditions at the metabolite level, amino acids, most notably proline increase to provide osmoprotective functions, prevent dissociation of enzymes and safeguard the cell from reactive oxygen species (ROS) (Kumar et al, 2011;Mehmood-ul-Hassan et al, 2013). Accordingly, genotypes which accumulate more proline are less prone to adverse effects of drought stress (Chandrasekar et al, 2000;Qayyum et al, 2017). The selected somaclones are also reported to accumulate more proline than parents with improved stress tolerance (Safarnejad, 2004;Verma et al, 2013).…”

“…Proteins and lipids are the major constituents of membranes. Drought induced metabolic changes associated with protein turnover have shown that rubisco, rubisco binding protein (RBP), rubisco activase (RA), dehydrins (DHN), ATP dependent calpain protease (Clp) proteins and some heat shock proteins (HSP) are substantially increased in both drought tolerant and susceptible cultivars of wheat in response to drought stress, with higher increment in tolerant ones (Demirevska et al, 2008;Qayyum et al, 2017). Therefore, under drought conditions, the protein contents are increased substantially in the root and shoot tissues of wheat (Tayeb & Ahmed, 2010) affirming the results of the present study ( Figure 2).…”

“…The results showed an increasing trend for sugar accumulation and the response was more pronounced against moisture stress of 4 th , 6 th and 8 th days, with significantly higher sugar contents portrayed by R 1 somaclones (Figure 3). A significant increment in the soluble sugar content of drought tolerant and sensitive genotypes has been reported in response to drought stress (Marcińska et al, 2013;Cheng et al, 2015;Qayyum et al, 2017). However, drought tolerant genotypes/plants tend to accumulate more soluble sugar contents than sensitive ones (Marcińska et al, 2013;Qayyum et al, 2017).…”

Drought stress is the most prevalent environmental factor limiting wheat productivity globally and demands integration of new plant improvement approaches. Plant tissue culture, being a mutagenic process induces somaclonal variations, which can be manipulated for improving drought tolerance of wheat. An in vitro selection system was employed to regenerate PEG-6000 tolerant callus lines into R 1 somaclones. Comparative morpho-physiologcial responses of R 1 somaclones and explant donor parent cultivar to osmotic stress were studied at seedling and booting stages by inducing artificial drought stress along with the control of unstressed. Both R 1 somaclones and explant donor parent exhibited differential responses to drought stress at both growth stages and the selected somaclones were less affected by drought stress over their donor parent. At seedling stage, the R 1 somaclones exhibited significantly higher root length, shoot length, root to shoot length ratio and relative water contents (RWC) under PEG-6000 induced osmotic stress. Similarly, at booting stage the R 1 somaclones accumulated significantly higher proline, protein, sugar and potassium ion (K +) contents and maintained higher membrane stability index (MSI) than the original cv. GA-2002 under drought stress conditions. The results revealed that the R 1 somaclones of wheat regenerated from PEG-6000 tolerant calli have better drought tolerance than the explant donor parent cv. GA-2002, suggesting that in vitro immature embryo culture can be employed to produce drought tolerant plants of wheat.

“…•− , OH • or O 2 ) is greater than the activity of the antioxidant response system, thus bringing severe consequences, with damage to lipids, proteins and DNA, culminating in cell death [28]. Plants in turn eliminate these free radicals by antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), and other enzymes, which, when associated, cause cellular detoxification [6].…”

This study presents the main changes that occur in the metabolism of corn plants submitted to water deficiency, which can directly affect the development and production of the plants. The aim of this study was to evaluate the biochemical and physiological metabolism responses in maize plants submitted to water deficiency. The experimental design was a randomized block in factorial scheme (3 × 3), being three irrigation depths and three evaluation periods with four replications. The treatments simulated two levels of water deficiency and one control: T1 (control treatment) 10-20 kPa; T2 (moderate water deficiency) 50-60 kPa, and T3 (severe water deficiency) 70-80 kPa. The evaluation periods were E1-45 days after emergence (DAE); E2-52 DAE; and E3-59 DAE. The variables analyzed were relative water content; electrolyte leakage; total soluble proteins; nitrate reductase activity; and activity of the antioxidative response system, namely superoxide dismutase, catalase, and peroxidase. The results showed that stress caused a decrease in the relative water content, reflecting changes in membrane permeability and possible induction of electrolyte losses and an increase in the activities of the enzymes of the antioxidative response system. Thus, corn plants submitted to water deficiency presented interactive responses as a strategy to mitigate the impact of stress.
