Abstract
Safranal is a free radical scavenger and useful as an antioxidant molecule; however, its promotive role in soybean is not explored. Salt stress decreased soybean growth and safranal improved it even if under salt stress. To study the positive mechanism of safranal on soybean growth, a proteomic approach was used. According to functional categorization, oppositely changed proteins were further confirmed using biochemical techniques. Actin and calcium-dependent protein kinase decreased in soybean root and hypocotyl, respectively, under salt stress and increased with safranal application. Xyloglucan endotransglucosylase/ hydrolase increased in soybean root under salt stress but decreased with safranal application. Peroxidase increased under salt stress and further enhanced by safranal application in soybean root. Actin, RuvB-like helicase, and protein kinase domain-containing protein were upregulated under salt stress and further enhanced by safranal application under salt stress. Dynamin GTPase was downregulated under salt stress but recovered with safranal application under salt stress. Glutathione peroxidase and PfkB domain-containing protein were upregulated by safranal application under salt stress in soybean root. These results suggest that safranal improves soybean growth through the regulation of cell wall and nuclear proteins along with reactive‑oxygen species scavenging system. Furthermore, it might promote salt-stress tolerance through the regulation of membrane proteins involved in endocytosis and post-Golgi trafficking.

Abstract
RuvBL, is a member of SF6 superfamily of helicases and is conserved among the various model systems. Recently, rice (Oryza sativa L.) homolog of RuvBL has been biochemically characterized for its ATPase and DNA helicase activities; however its involvement in stress has not been studied so far. Present investigation reports the detailed functional characterization of OsRuvBL under abiotic stresses through genetic engineering. An efficient Agrobacterium-mediated in planta transformation protocol was developed in indica rice to generate the transgenic lines and study was focused on optimization of factors to achieve maximum transformation efficiency. Overexpressing OsRuvBL1a transgenic lines showed enhanced tolerance under in vivo salinity stress as compared to WT plants. The physiological and biochemical analysis of the OsRuvBL1a transgenic lines showed better performance under salinity and drought stresses. Several stress responsive interacting partners of OsRuvBL1a were identified using Y2H system revealed to its role in stress tolerance. Functional mechanism for boosting stress tolerance by OsRuvBL1a has been proposed in this study. This integration of OsRuvBL1a gene in rice genome using in planta transformation method helped to achieve the abiotic stress resilient smart crop. This study is the first direct evidence to show the novel function of RuvBL in boosting abiotic stress tolerance in plants.

Identification and characterization of RuvBL DNA helicase genes for tolerance against abiotic stresses in bread wheat (Triticum aestivum L.) and related species. Funct Integr Genomics 2023; 23:255. [PMID: 37498392 DOI: 10.1007/s10142-023-01177-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 07/13/2023] [Accepted: 07/13/2023] [Indexed: 07/28/2023]
Abstract
Recombination UVB (sensitivity) like (RuvBL) helicase genes represent a conserved family of genes, which are known to be involved in providing tolerance against abiotic stresses like heat and drought. We identified nine wheat RuvBL genes, one each on nine different chromosomes, belonging to homoeologous groups 2, 3, and 4. The lengths of genes ranged from 1647 to 2197 bp and exhibited synteny with corresponding genes in related species including Ae. tauschii, Z. mays, O. sativa, H. vulgare, and B. distachyon. The gene sequences were associated with regulatory cis-elements and transposable elements. Two genes, namely TaRuvBL1a-4A and TaRuvBL1a-4B, also carried targets for a widely known miRNA, tae-miR164. Gene ontology revealed that these genes were closely associated with ATP-dependent formation of histone acetyltransferase complex. Analysis of the structure and function of RuvBL proteins revealed that the proteins were localized mainly in the cytoplasm. A representative gene, namely TaRuvBL1a-4A, was also shown to be involved in protein-protein interactions with ten other proteins. On the basis of phylogeny, RuvBL proteins were placed in two sub-divisions, namely RuvBL1 and RuvBL2, which were further classified into clusters and sub-clusters. In silico studies suggested that these genes were differentially expressed under heat/drought. The qRT-PCR analysis confirmed that expression of TaRuvBL genes differed among wheat cultivars, which differed in the level of thermotolerance. The present study advances our understanding of the biological role of wheat RuvBL genes and should help in planning future studies on RuvBL genes in wheat including use of RuvBL genes in breeding thermotolerant wheat cultivars.

Abstract
The recovery and maintenance of plant homeostasis under stressful environments are complex processes involving organelle crosstalk for a coordinated cellular response. Here, we revealed through nuclear and chloroplast subcellular proteomics, biochemical cell profiles and targeted transcriptomics how chloroplasts and nuclei developed their responses under increased temperatures in a long-lived species (Pinus radiata). Parallel to photosynthetic impairment and reactive oxygen species production in the chloroplast, a DNA damage response was triggered in the nucleus followed by an altered chromatin conformation. In addition, in the nuclei, we found several proteins, such as HEMERA or WHIRLY, which change their locations from the chloroplasts to the nuclei carrying the stress message. Additionally, our data showed a deep rearrangement of RNA metabolism in both organelles, revealing microRNAs and AGO1 as potential regulators of the acclimation mechanisms. Altogether, our study highlights the synchronisation among the different stages required for thermotolerance acquisition in P. radiata, pointing out the role of chromatin conformation and posttranscriptional gene regulation in overcoming heat stress and assuring plant survival for the following years.

Int J Mol Sci 2020; 21:ijms21041443.

Abstract
Fatty acids (FAs) have been implicated in signaling roles in plant defense responses. We previously reported that mutation or RNAi-knockdown (OsSSI2-kd) of the rice OsSSI2 gene, encoding a stearoyl acyl carrier protein FA desaturase (SACPD), remarkably enhanced resistance to blast fungus Magnaporthe oryzae and the leaf-blight bacterium Xanthomonas oryzae pv. oryzae (Xoo). Transcriptomic analysis identified six AAA-ATPase family genes (hereafter OsAAA-ATPase1–6) upregulated in the OsSSI2-kd plants, in addition to other well-known defense-related genes. Here, we report the functional analysis of OsAAA-ATPase1 in rice’s defense response to M. oryzae. Recombinant OsAAA-ATPase1 synthesized in Escherichia coli showed ATPase activity. OsAAA-ATPase1 transcription was induced by exogenous treatment with a functional analogue of salicylic acid (SA), benzothiadiazole (BTH), but not by other plant hormones tested. The transcription of OsAAA-ATPase1 was also highly induced in response to M. oryzae infection in an SA-dependent manner, as gene induction was significantly attenuated in a transgenic rice line expressing a bacterial gene (nahG) encoding salicylate hydroxylase. Overexpression of OsAAA-ATPase1 significantly enhanced pathogenesis-related gene expression and the resistance to M. oryzae; conversely, RNAi-mediated suppression of this gene compromised this resistance. These results suggest that OsAAA-APTase1 plays an important role in SA-mediated defense responses against blast fungus M. oryzae.

Abstract
Salt stress response includes alteration in the activity of various important enzymes in plants. Nitrate reductase (NR) is one of the known enzyme affected by salt stress. In this study, contrasting salt responsive cultivars (CVS) (IR64-sensitive and CSR 36-tolerant) were considered to study the regulation of NR genes under salt stress conditions. Using Arabidopsis genes Nia1 and Nia2, three different NR genes were identified in rice and their expression study was conducted. Under stress condition, salt-sensitive CVS (IR64) showed a decrease in NR activity under in vitro and in vivo conditions, whereas tolerant CVS showed an increase in NR activity. Different trends for NR activity in contrasting genotype are explained by the variable number of GATA element in the upstream region of the NR gene. This variation of NR activity in contrasting CVS further co-relates with the transcript level of NR genes. The transcript level of three different NR genes also evidenced the effect of CREs in gene regulation. Promoter (1-kb upstream region) of different NR genes contained different abiotic stress-responsive CREs, which explain the differential behavior of these genes towards the abiotic stress. Overall, this study concludes the role of CREs in the regulation of NR gene and indicates the importance of transcriptional control of NR activity under stress condition. This is the first type of report that highlights the role of the regulatory mechanism of NR genes under salt stress condition.
