Abstract
Vacuole largely dictates the fruit taste and flavor, as most of the sugars and organic acids are stored in the vacuoles of the fruit. However, difficulties associated with vacuole separation severely hinder identification and characterization of vacuolar proteins in fruit species. In this study, we established an effective approach for separating vacuoles and successfully purified vacuolar protein from six types of citrus fruit with varying patterns of sugar and organic acid contents. By using label-free LC-MS/MS proteomic analysis, 1443 core proteins were found to be associated with the essential functions of vacuole in citrus fruit. Correlation analysis of metabolite concentration with proteomic data revealed a transporter system for the accumulation of organic acid and soluble sugars in citrus. Furthermore, we characterized the physiological roles of selected key tonoplast transporters, ABCG15, Dict2.1, TMT2, and STP7 in the accumulation of citric acid and sugars. These findings provide a novel perspective and practical solution for investigating the transporters underlying the formation of citrus taste and flavor.

Mol Cell Biochem 2023:10.1007/s11010-023-04805-0. [PMID: 37522975 DOI: 10.1007/s11010-023-04805-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Accepted: 07/01/2023] [Indexed: 08/01/2023]
Abstract
Cyclophosphamide has drastically enhanced the expectancy and quality of life of cancer patients. However, it is accompanied by diverse neurological complications which are considered a dose-limiting adverse effect. Neurotoxicity caused by cyclophosphamide can manifest in numerous manners including anxiety, depression, motor dysfunction and cognitive deficits. This review article offers an overview on cyclophosphamide-induced neurotoxicity, providing a unified point of view on the possible underlying molecular mechanisms including oxidative brain damage, neuroinflammation, apoptotic neuronal cell death as well as disruption of the balance of brain neurotransmitters and neurotrophic factors. Besides, this review sheds light on the promising protective agents that have been investigated using preclinical animal models as well as their biological targets and protection mechanisms. Despite promising results in experimental models, none of these agents has been studied in clinical trials. Thus, there is lack of evidence to advocate the use of any neuroprotective agent in the clinical setting. Furthermore, none of the protective agents has been evaluated for its effect on the anticancer activity of cyclophosphamide in tumor-bearing animals. Therefore, there is a great necessity for adequate well-designed clinical studies for evaluation of the therapeutic values of these candidates. Conclusively, this review summarizes the molecular mechanisms accounting for cyclophosphamide-induced neurotoxicity together with the potential protective strategies seeking for downgrading this neurological complication, thus enhancing the quality of life and well-being of cancer patients treated with cyclophosphamide.

Abstract
Osmotic stress can occur due to some stresses such as salinity and drought, threatening plant survival. To investigate the mechanism governing the pistachio response to this stress, the biochemical alterations and protein profile of PEG-treated plants was monitored. Also, we selected two differentially abundant proteins to validate via Real-Time PCR. Biochemical results displayed that in treated plants, proline and phenolic content was elevated, photosynthetic pigments except carotenoid decreased and MDA concentration were not altered. Our findings identified a number of proteins using 2DE-MS, involved in mitigating osmotic stress in pistachio. A total of 180 protein spots were identified, of which 25 spots were altered in response to osmotic stress. Four spots that had photosynthetic activities were down-regulated, and the remaining spots were up-regulated. The biological functional analysis of protein spots exhibited that most of them are associated with the photosynthesis and metabolism (36%) followed by stress response (24%). Results of Real-Time PCR indicated that two of the representative genes illustrated a positive correlation among transcript level and protein expression and had a similar trend in regulation of gene and protein. Osmotic stress set changes in the proteins associated with photosynthesis and stress tolerance, proteins associated with the cell wall, changes in the expression of proteins involved in DNA and RNA processing occur. Findings of this research will introduce possible proteins and pathways that contribute to osmotic stress and can be considered for improving osmotic tolerance in pistachio.

Abstract
In the present study, influence of nitrate concentration on in vitro rooting and its ex vitro hardened tubers were investigated in D. hamiltonii. In vitro multiple shoots established on the MS medium were used as explants for this study and concentration of indole-3-butyric acid (1.23 µM) required for root initiation was determined. The effect of different nitrate concentrations in MS medium for in vitro rooting was investigated and positive (¼ and ½ strength) influence was observed on 14 days inoculation. The in vitro rooted plants (IVP) showed 80% survival upon hardening and exhibited similar growth pattern to seedling plants. The 1-year grew ex vitro hardened plants were evaluated for their tuber quality with reference to their yield and flavor metabolite 2-hydroxy-4-methoxy benzaldehyde (2H4MB) content. The IVP grown from ¼ nitrate strength media produced 155 ± 4.85 g FW of tuber biomass which is observed to be higher than full nitrate strength IVP (112 ± 2.52 g) which are grown under similar conditions in the greenhouse. The flavor metabolite content, total phenolics, total flavonoids, and antioxidant potential of these IVP tubers were evaluated. Upregulation of flavor biosynthetic pathway genes DhPAL, DhC4H and DhCoMT were observed in tubers of potted plants that developed from low nitrate strength culture media. In this study, superiority of tissue cultured plants was evident, wherein in vitro plants developed in low nitrate strength medium and acclimatized could produce a higher yield in tuber biomass and maintain relative content of flavor compounds in this endangered plant.
