PLANT CELL REPORTS 2024; 43:140. [PMID: 38740586 DOI: 10.1007/s00299-024-03178-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Accepted: 02/19/2024] [Indexed: 05/16/2024]
Abstract
KEY MESSAGE The utilization of transcriptome analysis, functional validation, VIGS, and DAB techniques have provided evidence that GhiPLATZ17 and GhiPLATZ22 play a pivotal role in improving the salt tolerance of upland cotton. PLATZ (Plant AT-rich sequences and zinc-binding proteins) are known to be key regulators in plant growth, development, and response to salt stress. In this study, we comprehensively analyzed the PLATZ family in ten cotton species in response to salinity stress. Gossypium herbaceum boasts 25 distinct PLATZ genes, paralleled by 24 in G. raimondii, 25 in G. arboreum, 46 in G. hirsutum, 48 in G. barbadense, 43 in G. tomentosum, 67 in G. mustelinum, 60 in G. darwinii, 46 in G. ekmanianum, and a total of 53 PLATZ genes attributed to G. stephensii. The PLATZ gene family shed light on the hybridization and allopolyploidy events that occurred during the evolutionary history of allotetraploid cotton. Ka/Ks analysis suggested that the PLATZ gene family underwent intense purifying selection during cotton evolution. Analysis of synteny and gene collinearity revealed a complex pattern of segmental and dispersed duplication events to expand PLATZ genes in cotton. Cis-acting elements and gene expressions revealed that GhiPLATZ exhibited salt stress resistance. Transcriptome analysis, functional validation, virus-induced gene silencing (VIGS), and diaminobenzidine staining (DAB) demonstrated that GhiPLATZ17 and GhiPLATZ22 enhance salt tolerance in upland cotton. The study can potentially advance our understanding of identifying salt-resistant genes in cotton.

Whole-genome identification and multiple abiotic stresses expression pattern profiling analysis of PLATZ transcription factor family members in Pecan (Carya illinoensis). Int J Biol Macromol 2023; 248:125959. [PMID: 37495003 DOI: 10.1016/j.ijbiomac.2023.125959] [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: 03/10/2023] [Revised: 07/03/2023] [Accepted: 07/13/2023] [Indexed: 07/28/2023]
Abstract
Plant AT-rich sequence and zinc-binding (PLATZ), as a plant-specific transcription factor, have been identified and studied in a variety of plants. However, there are no reports about PLATZ proteins in Carya illinoensis (pecan). Here, 24 C. illinoensis CiPLATZs have been identified and divided into 4 groups. Gene structure, motif composition, conserved domain and cis-acting elements analysis indicated that the PLATZ gene family was highly conserved. Transcriptome data combined with qRT-PCR analysis revealed that CiPLATZ6, CiPLATZ12, CiPLATZ13, CiPLATZ14 and CiPLATZ23 were highly expressed in multiple tissues of C. illinoensis and strongly responded to drought, salt and heat stress. Among them, CiPLATZ6, CiPLATZ12 and CiPLATZ23 were all located in the nucleus and had no transcriptional autoactivation ability in yeast cells, and acted as transcriptional suppressors in plants. In addition, the CiPLATZ23-overexpressing transgenic Arabidopsis thaliana showed enhanced tolerance to drought. Measurements of physiological indicators and analysis of stress-related genes expression levels in transgenic A. thaliana were used to support this conclusion. The results of this study are helpful to understand the structural feature and function of CiPLATZs, and provide candidate genes for molecular breeding of drought tolerance of C. illinoensis.

Genome-wide characterization of the PLATZ gene family in watermelon (Citrullus lanatus L.) with putative functions in biotic and abiotic stress response. PLANT PHYSIOLOGY AND BIOCHEMISTRY : PPB 2023; 201:107854. [PMID: 37356384 DOI: 10.1016/j.plaphy.2023.107854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/20/2023] [Revised: 05/19/2023] [Accepted: 06/18/2023] [Indexed: 06/27/2023]
Abstract
Plant AT-rich sequence and zinc-binding (PLATZ) proteins are plant-specific transcription factors involved in growth, development, and stress responses. Here, we conducted a genome-wide characterization of the watermelon ClPLATZ family and examined its expression responsiveness to defense hormones and pathogen infection along with putative functions in biotic and abiotic stress responses. The watermelon genome contains 12 putative ClPLATZ genes, encoding proteins with a characteristic PLATZ domain, and their promoters contain various cis-elements related to plant growth, development, phytohormones and stress response. The ClPLATZ genes, except ClPLATZ6, are differentially expressed in response to defense hormones (e.g., salicylic acid and methyl jasmonate) and fungal infections caused by Fusarium oxysporum f. sp. niveum and Stagonosporopsis cucurbitacearum. Most ClPLATZ proteins interact with other proteins (viz., ClDP, ClRPT2a, and ClRPC53). Among ClPLATZ proteins, ClPLATZ8, 9, 10, and 11 are predominately localized in the nucleus. ClPLATZ3 and 8 positively, but ClPLATZ11 negatively regulate resistance against Pseudomonas syringe pv. tomato DC3000 in transgenic Arabidopsis lines. ClPLATZ8 and 11 positively regulate stress tolerance to NaCl and mannitol during seed germination in transgenic Arabidopsis. In conclusion, the characterization of the ClPLATZ family provides insights into the biological functions of ClPLATZ genes in growth, development, and stress response in watermelon. Further, the involvement of certain ClPLATZ genes in biotic and abiotic stress response in transgenic Arabidopsis suggests their potential application in engineering stress-tolerant crops.

BMC Genomics 2023; 24:329. [PMID: 37322464 DOI: 10.1186/s12864-023-09399-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2023] [Accepted: 05/23/2023] [Indexed: 06/17/2023] Open
Abstract
BACKGROUND Branching is a plastic character that affects plant architecture and spatial structure. The trait is controlled by a variety of plant hormones through coordination with environmental signals. Plant AT-rich sequence and zinc-binding protein (PLATZ) is a transcription factor that plays an important role in plant growth and development. However, systematic research on the role of the PLATZ family in apple branching has not been conducted previously. RESULTS In this study, a total of 17 PLATZ genes were identified and characterized from the apple genome. The 83 PLATZ proteins from apple, tomato, Arabidopsis, rice, and maize were classified into three groups based on the topological structure of the phylogenetic tree. The phylogenetic relationships, conserved motifs, gene structure, regulatory cis-acting elements, and microRNAs of the MdPLATZ family members were predicted. Expression analysis revealed that MdPLATZ genes exhibited distinct expression patterns in different tissues. The expression patterns of the MdPLATZ genes were systematically investigated in response to treatments that impact apple branching [thidazuron (TDZ) and decapitation]. The expression of MdPLATZ1, 6, 7, 8, 9, 15, and 16 was regulated during axillary bud outgrowth based on RNA-sequencing data obtained from apple axillary buds treated by decapitation or exogenous TDZ application. Quantitative real-time PCR analysis showed that MdPLATZ6 was strongly downregulated in response to the TDZ and decapitation treatments, however, MdPLATZ15 was significantly upregulated in response to TDZ, but exhibited little response to decapitation. Furthermore, the co-expression network showed that PLATZ might be involved in shoot branching by regulating branching-related genes or mediating cytokinin or auxin pathway. CONCLUSION The results provide valuable information for further functional investigation of MdPLATZ genes in the control of axillary bud outgrowth in apple.
