“…An internal isotopic standard mixture consisting of deuterated IAA and ABA, and kinetin labelled with nitrogen 15 N was added to each sample during homogenisation. The prepared extract was fractionated using solid phase extraction (SPE) columns Oasis MCX (Waters), and three fractions were collected: "acidic" eluted with methanol for IAA and ABA analyses according to HPLC method of Štefančič et al (2007), "basic" eluted with methanolic solution of ammonia for cytokinins analyses according to Żur et al (2015), and "flow through" for carbohydrates analyses according to Hura et al (2016).…”

of explant excision, a dramatic reduction in concentration of all phytohormones studied was observed, but hormonal balance and sugar content remained almost unchanged. During the 14-day-long culture, the ABA/CKs and ABA/ IAA ratios remained constant, whereas the greatest differences were detected for the IAA/CKs and Z-type/iPA cytokinin ratios. Excluding day 6 of culture, cytokinins were found to be the predominant phytohormones over IAA. An almost 12-fold increase in soluble sucrose concentration at day 6 of culture might be the switch to the SE expression phase. Frequent cell divisions leading to somatic embryo formation are clearly associated with increase in trans-zeatin riboside content. Keywords

“…Carbohydrate content of the plants is regulated by the rate of photosynthesis, as well as polysaccharides hydrolysis and cellular export under drought stress therefore may demonstrate either increased or decreased carbohydrate pool which is determined by the extent of the carbohydrate deranged metabolism. 14 Additionally, drought stress can lead to cell death in part by decreasing the content of the carbohydrates. 41 This may be partly related to the impacts of drought stress on plant physiological processes including reduced photosynthesis which are due to the stomatal constriction, increased metabolic demand for carbohydrates, elevated carbohydrates metabolization, and finally shrinkage of the carbohydrates storages leading to carbon depletion.…”

“…This is mainly triggered by regulating the cellular osmotic capacity and preserving the intracellular water. 14 Micronutrient fertilizers are suggested as potential agents which increase the tolerance of plants to drought stress. By conserving membrane integrity and cellular potassium content, zinc (Zn) is essential in regulating the stomatal function by inducing the stomatal closure and preventing the transpiration in plants under waterdeficit conditions.…”

Introduction: Moringa peregrina (Forssk.) Fiori as a desert tree has economic, nutritional, and medicinal properties, and is constantly encountered with drought stress. In addition, the role of zinc oxide nanoparticles (ZnO-NPs) in regulating the drought stress which induces biochemical processes is uncertain in this plant. Therefore, this study aimed to investigate the biochemical alternations, namely, enzymatic and osmoprotectant which are induced by ZnO-NPs in ten populations of M. peregrina under drought stress. Materials and Methods: Moringa peregrina seeds were collected from southeast of Iran in 2014. The young plants were exposed to drought stress by withholding irrigation (until 50% filed capacity [FC]) 40 days after germination followed by spraying 0 (as control), 0.05, and 0.1% of the ZnO-NPs. Results: The alternations of Na/K ratio, enzymes activities, and osmoprotectant content varied under drought stress depending on the M. peregrina populations. Generally, drought stress significantly enhanced peroxidase (POD) and polyphenol oxidase (PPO) activities, as well as proline content in untreated plants. Further, the Na/K ratio and carbohydrates content significantly decreased under the drought stress. Furthermore, ZnO-NP treatment significantly enhanced POD and PPO activities, as well as proline and carbohydrates content under both well-watered (100% FC) and drought stress conditions (50% FC), and at the concentration of 0.05% rather than 0.1%, ZnO-NPs was more effective. Conclusion: Overall, ZnO-NP treatment could effectively improve the drought tolerance by enhancing the enzymes activities and osmoprotectant content in different M. peregrina populations under drought stress. Therefore, foliar application of ZnO-NPs at 0.05% concentration could be a recommended treatment for growing different M. peregrina populations under drought stress conditions.
