“…Ziziphus nummularia also show tolerance to heat stress. Here, the chaperone protein ClpB1, which plays an important role in thermotolerance, was investigated [54]. It was found that the transcript levels of the JClpB1-C isoform from a heat-tolerant Ziziphus nummularia ecotype was highly up-regulated under heat stress conditions and that the overexpression of ZnJCIpB1-C in tobacco showed a significant increase in its heat tolerance by exhibiting higher photosynthetic rates, relative water content, chlorophyll content, and membrane stability index, suggesting that Ziziphus nummularia could provide an important source for developing heat-stress tolerant germplasms.…”

Ziziphus nummularia, a small bush of the Rhamnaceae family, has been widely used in traditional folk medicine, is rich in bioactive molecules, and has many reported pharmacological and therapeutic properties. Objective: To gather the current knowledge related to the medicinal characteristics of Z. nummularia. Specifically, its phytochemical contents and pharmacological activities in the treatment of various diseases such as cancer, diabetes, and cardiovascular diseases, are discussed. Methods: Major scientific literature databases, including PubMed, Scopus, ScienceDirect, SciFinder, Chemical Abstracts, Medicinal and Aromatic Plants Abstracts, Henriette′s Herbal Homepage, Dr. Duke′s Phytochemical and Ethnobotanical Databases, were searched to retrieve articles related to the review subject. General web searches using Google and Google scholar were also utilized. The search period covered articles published between 1980 and the end of October 2021.The search used the keywords ‘Ziziphus nummularia’, AND (‘phytochemical content’, ‘pharmacological properties, or activities, or effects, or roles’, ‘anti-inflammatory’, ‘anti-drought’, ‘anti-thermal’, ‘anthelmintic’, ‘antidiabetic’,’ anticancer’, ‘anticholinesterase’, ‘antimicrobial’, ‘sedative’, ‘antipyretic’, ‘analgesic’, or ‘gastrointestinal’). Results: This plant is rich in characteristic alkaloids, especially cyclopeptide alkaloids such as nummularine-M. Other phytochemicals, including flavonoids, saponins, glycosides, tannins, and phenolic compounds, are also present. These phytochemicals are responsible for the reported pharmacological properties of Z. nummularia, including anti-inflammatory, antioxidant, antimicrobial, anthelmintic, antidiabetic, anticancer, analgesic, and gastrointestinal activities. In addition, Z. nummularia has anti-drought and anti-thermal characteristics. Conclusion: Research into the phytochemical and pharmacological properties of Z. nummularia has demonstrated that this plant is a rich source of novel bioactive compounds. So far, Z. nummularia has shown a varied pharmacological profile (antioxidant, anticancer, anti-inflammatory, and cardioprotective), warranting further research to uncover the therapeutic potential of the bioactives of this plant. Taken together, Z. nummularia may represent a new potential target for the discovery of new drug leads.

“…In addition, since high temperatures lead to drought, pathways of temperature acclimatization are activated in Q. ilex cells through the up-regulation of caseinolytic peptidase B (ClpB1, ClpB3) and small heat-shock protein Hsp22. Panzade et al [75] found that a rapid increase in the expression level of the ZnJClpB 1-C gene (Ziziphus nummularia) in transgenic Nicotiana tobaccum cv. 'Benthamiana' under heat stress indicates protection against protein denaturation.…”

Betula spp., Quercus spp., and Populus spp. are the most promising deciduous woody plants in forestry. However, these species were found to be sensitive to climate change that can badly affect their plantations. Thus, a deep understanding of genetic mechanisms of adaptation to adverse environmental conditions plays an important role in preventing the reduction of deciduous forest area. This mini review describes the stress responses of Betula spp., Quercus spp., and Populus spp. to drought and salt stresses. The overall stress response of the reviewed tree species includes ROS scavenging, ABA- and JA-mediated signaling pathways, and antioxidant and chaperone activities. Short-term drought promotes accumulation of proline, indicating the osmotic stress response. In turn, long-term drought stress activates the DNA repair and chromatin remodeling systems aimed at adapting and gene protecting. Furthermore, alternative pathways of carbohydrate production are used under nutrient deficiencies. It should be noted that stomatal movement control and cell wall remodeling are always observed during drought. In turn, the main response to salt stress includes the maintenance of ion homeostasis and the accumulation of osmoprotectant, as well as cell wall remodeling due to the biosynthesis of cellulotic and non-cellulotic cell wall compounds. It should be noted that the described species demonstrate similar molecular traits for adaptation to drought and salt stress, which may be due to their common habitats.

“…A variety of candidate genes have been introduced into different plants where varying degrees of increased heat tolerance have been achieved in the transgenic lines. The functions of the genes that were introduced into transgenic plants span across a diverse collection of activities such as transcription factors (Qi et al 2018;El-Esawi et al 2019), quantitative trait loci related to heat stress (Acuña-Galindo et al 2015;Wen et al 2019), heat shock proteins (HSPs)/chaperone proteins (Panzade et al 2020;Wang et al 2020), heat shock factors (HSFs) (Wang et al 2017), osmolytes (Cvikrová et al 2012), regulatory proteins participating in oxidative stress signaling (Lin et al 2015;Ali et al 2020;Ghosh et al 2020), hormonal signaling (Bi et al 2020), and abiotic stress response pathways (Zang et al 2017;Lamaoui et al 2018;Nadeem et al 2018). Among these approaches, studies related to the photosynthetic machinery would seem like a winning strategy since the efficiency of photosynthesis ultimately determines plant biomass and yield, which makes sense in an economical scale and it directly translates into increased productivity (Antonovsky et al 2017).…”

With the rapid growth of world population, it is essential to increase agricultural productivity to feed the growing population. Over the past decades, many methods have been used to increase crop yields. Despite the success in boosting the crop yield through these methods, global food production still needs to be increased to be on par with the increasing population and its dynamic consumption patterns. Additionally, given the prevailing environmental conditions pertaining to the global temperature increase, heat stress will likely be a critical factor that negatively affects plant biomass and crop yield. One of the key elements hindering photosynthesis and plant productivity under heat stress is the thermo-sensitivity of the Rubisco activase (RCA), a molecular chaperone that converts Rubisco back to active form after it becomes inactive. It would be an attractive and practical strategy to maintain photosynthetic activity under elevated temperatures by enhancing the thermo-stability of RCA. In this context, this review discusses the need to improve the thermo-tolerance of RCA under current climatic conditions and to further study RCA structure and regulation, and its limitations at elevated temperatures. This review summarizes successful results and provides a perspective on RCA research and its implication in improving crop yield under elevated temperature conditions in the future.
