“…Plants respond to environmental stress by accumulating certain compatible permeates, such as proline, which is known to induce drought tolerance [28]. Moreover, the upregulation of proline-metabolizing genes and the increase in proline content under drought stress in our experimental results are clear evidence of the induced tolerance of P. ostii.…”

“…Moreover, compared with the control, the water content of drought-treated leaves also decreased significantly with the development of drought stress. The leaf is an important organ that consumes water, and its changes under different water supply conditions show the importance of maintaining the water balance in plants [28]. These phenomena are broadly reported, and acutely described in studies on grapevine [29] and wheat [30].…”

Tree peony (Paeonia section Moutan DC.) is a famous ornamental plant, and P. ostii has been used for seed oil production in China because it is rich in α-linolenic acid. P. ostii has some resistance to drought, but lack of water can severely hinder its growth and development in arid areas. In order to clarify drought stress induced physiological and molecular changes of P. ostia, its physiological and transcriptomic analyses were performed under drought stress, and we found that P. ostii leaves drooped significantly 12 days after treatment and observed a significant increase in all detected physiological indices in response to drought treatment except leaf water content, chlorophyll, and carotenoid content. Meanwhile, the activity of three antioxidant enzymes basically increased under drought treatment. Moreover, drought treatment significantly reduced photosynthetic and chlorophyll fluorescence parameters except non-photochemical quenching (qN), and maintained more intact mesophyll cell structures. Additionally, many differentially expressed genes (DEGs) were found by transcriptome sequencing, which play an important role in P. ostia drought tolerance by controlling a variety of biological processes, including the reactive oxygen species (ROS) system, chlorophyll degradation and photosynthetic competency, fatty acid metabolism, proline metabolism, biosynthesis of secondary metabolism, and plant hormone metabolism. These results provide a better understanding of P. ostii responses to drought stress.

“…Thus, water deficit stress could reduce safflower height if it occurs during growing stages. This height reduction could be due to an interruption in the photosynthesis process during the water deficit period, leading to a decreased transfer of photo-assimilates to growing sections of crops [15].…”

“…Similar to the results of this study, Hojati et al [6] reported a significant reduction in RWC after inducing water deficit stress in safflower. RWC is a more reliable criterion for evaluating water status in plant tissues than cell water potential, as RWC is directly associated with cell volume and therefore can better represent the balance between crop water content and transpiration rate [15]. Eslam [27] also showed that RWC can used to select optimal safflower genotypes for water deficit stress conditions.…”

Safflower (<em>Carthamus tinctorius</em> L.) is an oilseed crop adapted to arid and semiarid regions. In this study, an experiment was performed to evaluate the effects of water deficiency on plant height, 1,000-grain weight, seed yield, harvest index, relative water content (RWC), oil yield, and oil content in 15 safflower genotypes. A split-plot randomized complete blocks design was arranged with three replications. Safflower plants were grown under normal irrigation and water deficit conditions in Sarvestan, Fars Province, Iran during 2016 and 2017 growing seasons. Combined analysis results indicated that water deficit stress had negative effects on all measured indices. Average seed yield declined by 65.91% (2,337.91 to 796.79 kg ha<sup>−1</sup>) due to water deficit stress. Genotype also had a significant effect on evaluated indices, and the interaction between genotype and irrigation significantly influenced all indices except plant height. Under both conditions, highest RWC, seed yield, and oil yield were observed in Dincer and PI-537598 genotypes. Maximum plant height and 1,000-seed weight in both irrigation conditions were observed in the Dincer genotype. In the normal irrigation condition, maximum harvest index and oil content were observed in the CW-74 genotype. Thus, Dincer and PI-537598 were classified as the best genotypes (based on seed yield, RWC, and oil yield) under both normal irrigation and water deficit stress conditions.
