Tran Thi Ngoc A, Nguyen Van K, Lee YH. DnaJ, a heat shock protein 40 family member, is essential for the survival and virulence of plant pathogenic Pseudomonas cichorii JBC1. Res Microbiol 2023; 174:104094. [PMID: 37356782 DOI: 10.1016/j.resmic.2023.104094] [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: 02/05/2023] [Revised: 06/12/2023] [Accepted: 06/20/2023] [Indexed: 06/27/2023]
Abstract
Bacterial plant pathogens must cope with various environmental conditions and defenses from their hosts for colonization and infection. Heat shock proteins (HSPs) play critical roles in a variety of cellular processes, such as the maintenance of cellular homeostasis in response to environmental stress. However, the significance of HSP40 family protein DnaJ in virulence of plant pathogenic bacteria has not yet been explored. To elucidate the function of DnaJ in Pseudomonas cichorii JBC1 (PcJBC1) virulence, we generated dnaJ-deficient (JBC1ΔdnaJ) mutant using CRISPR-CAS9. The disease severity by JBC1ΔdnaJ was significantly reduced compared with wild-type (WT) and dnaJ-complemented (JBC1ΔdnaJ + pdnaJ) strain. The defect of DnaJ suppressed siderophore production, extracellular DNA (eDNA) release, biofilm formation, and swarming motility and made the strain sensitive to stresses such as heat and H2O2. The supplementation of eDNA recovered the amount of biofilm formation by JBC1ΔdnaJ. Our results indicate that DnaJ is a key player in the survival and colonization of bacterial plant pathogens on plant surfaces as well as bacterial responses to abiotic and biotic stresses, which are determinative to cause disease. These findings can broaden our understanding of plant and bacterial pathogen interactions.

Razzaq MK, Rani R, Xing G, Xu Y, Raza G, Aleem M, Iqbal S, Arif M, Mukhtar Z, Nguyen HT, Varshney RK, Siddique KHM, Gai J. Genome-Wide Identification and Analysis of the Hsp40/J-Protein Family Reveals Its Role in Soybean ( Glycine max) Growth and Development. Genes (Basel) 2023; 14:1254. [PMID: 37372434 DOI: 10.3390/genes14061254] [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: 04/27/2023] [Revised: 06/05/2023] [Accepted: 06/09/2023] [Indexed: 06/29/2023] Open
Abstract
The J-protein family comprises molecular chaperones involved in plant growth, development, and stress responses. Little is known about this gene family in soybean. Hence, we characterized J-protein genes in soybean, with the most highly expressed and responsive during flower and seed development. We also revealed their phylogeny, structure, motif analysis, chromosome location, and expression. Based on their evolutionary links, we divided the 111 potential soybean J-proteins into 12 main clades (I-XII). Gene-structure estimation revealed that each clade had an exon-intron structure resembling or comparable to others. Most soybean J-protein genes lacked introns in Clades I, III, and XII. Moreover, transcriptome data obtained from a publicly accessible soybean database and RT-qPCR were used to examine the differential expression of DnaJ genes in various soybean tissues and organs. The expression level of DnaJ genes indicated that, among 14 tissues, at least one tissue expressed the 91 soybean genes. The findings suggest that J-protein genes could be involved in the soybean growth period and offer a baseline for further functional research into J-proteins' role in soybean. One important application is the identification of J-proteins that are highly expressed and responsive during flower and seed development in soybean. These genes likely play crucial roles in these processes, and their identification can contribute to breeding programs to improve soybean yield and quality.

Translational profile of coding and non-coding RNAs revealed by genome wide profiling of ribosome footprints in grapevine. FRONTIERS IN PLANT SCIENCE 2023; 14:1097846. [PMID: 36844052 PMCID: PMC9944039 DOI: 10.3389/fpls.2023.1097846] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/14/2022] [Accepted: 01/23/2023] [Indexed: 06/18/2023]
Abstract
Translation is a crucial process during plant growth and morphogenesis. In grapevine (Vitis vinifera L.), many transcripts can be detected by RNA sequencing; however, their translational regulation is still largely unknown, and a great number of translation products have not yet been identified. Here, ribosome footprint sequencing was carried out to reveal the translational profile of RNAs in grapevine. A total of 8291 detected transcripts were divided into four parts, including the coding, untranslated regions (UTR), intron, and intergenic regions, and the 26 nt ribosome-protected fragments (RPFs) showed a 3 nt periodic distribution. Furthermore, the predicted proteins were identified and classified by GO analysis. More importantly, 7 heat shock-binding proteins were found to be involved in molecular chaperone DNA J families participating in abiotic stress responses. These 7 proteins have different expression patterns in grape tissues; one of them was significantly upregulated by heat stress according to bioinformatics research and was identified as DNA JA6. The subcellular localization results showed that VvDNA JA6 and VvHSP70 were both localized on the cell membrane. Therefore, we speculate that DNA JA6 may interact with HSP70. In addition, overexpression of VvDNA JA6 and VvHSP70, reduced the malondialdehyde (MDA) content, improved the antioxidant enzyme activity of superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD), increased the content of proline, an osmolyte substance, and affected the expression of the high-temperature marker genes VvHsfB1, VvHsfB2A, VvHsfC and VvHSP100. In summary, our study proved that VvDNA JA6 and the heat shock protein VvHSP70 play a positive role in the response to heat stress. This study lays a foundation for further exploring the balance between gene expression and protein translation in grapevine under heat stress.

Braun JE. Extracellular chaperone networks and the export of J-domain proteins. J Biol Chem 2022; 299:102840.

Abstract
An extracellular network of molecular chaperones protects a diverse array of proteins that reside in or pass through extracellular spaces. Proteins in the extracellular milieu face numerous challenges that can lead to protein misfolding and aggregation. As a checkpoint for proteins that move between cells, extracellular chaperone networks are of growing clinical relevance. J-domain proteins (JDPs) are ubiquitous molecular chaperones that are known for their essential roles in a wide array of fundamental cellular processes through their regulation of heat shock protein 70s. As the largest molecular chaperone family, JDPs have long been recognized for their diverse functions within cells. Some JDPs are elegantly selective for their "client proteins," some do not discriminate among substrates and others act cooperatively on the same target. The realization that JDPs are exported through both classical and unconventional secretory pathways has fueled investigation into the roles that JDPs play in protein quality control and intercellular communication. The proposed functions of exported JDPs are diverse. Studies suggest that export of DnaJB11 enhances extracellular proteostasis, that intercellular movement of DnaJB1 or DnaJB6 enhances the proteostasis capacity in recipient cells, whereas the import of DnaJB8 increases resistance to chemotherapy in recipient cancer cells. In addition, the export of DnaJC5 and concurrent DnaJC5-dependent ejection of dysfunctional and aggregation-prone proteins are implicated in the prevention of neurodegeneration. This review provides a brief overview of the current understanding of the extracellular chaperone networks and outlines the first wave of studies describing the cellular export of JDPs.
