Kaur A, Madhu, Sharma A, Singh K, Upadhyay SK. Investigation of two-pore K + (TPK) channels in Triticum aestivum L. suggests their role in stress response. Heliyon 2024; 10:e27814. [PMID: 38533012 PMCID: PMC10963239 DOI: 10.1016/j.heliyon.2024.e27814] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 02/28/2024] [Accepted: 03/07/2024] [Indexed: 03/28/2024] Open
Abstract
Two-pore K+ (TPK) channels are voltage-independent and involved in stress response in plants. Herein, we identified 12 TaTPK genes located on nine chromosomes in the Triticum aestivum genome. The majority of TaTPK genes comprised two exons. Each TaTPK channel comprised four transmembrane (TM) helices, N- and C-terminal ion-channel domains, two EF-hand domains and one 14-3-3 binding site. Additionally, highly conserved 'GYGD' motif responsible for K+ ion specificity, was found in between the TMs in both the ion-channel domains. Nine TaTPK channels were predicted to be localised at the plasma membrane, while three were vacuolar. The protein-protein and protein-chemical interactions indicated the coordinated functioning of the TaTPK channels with the other K+ transporters and their possible interaction with the Ca2+-signaling pathway. Expression studies suggested their importance in both vegetative and reproductive tissues development. Significantly modulated expression of various TaTPK genes during heat, drought, combined heat and drought and salt stresses, and after fungal infestation, depicted their function in stress responses. The miRNAs and transcription factors interaction analyses suggested their role in the hormone, light, growth and development-related, and stress-responsive signaling cascades. The current study suggested vital functions of various TaTPK genes, especially in stress response, and would provide an opportunity for their detailed characterization in future studies.

BMC Genomics 2023; 24:668.

Abstract
BACKGROUND The Gibberellic Acid-Stimulated Arabidopsis (GASA) gene family is widely involved in the regulation of plant growth, development, and stress response. However, information on the GASA gene family has not been reported in Chinese cabbage (Brassica rapa L. ssp. pekinensis). RESULTS Here, we conducted genome-wide identification and analysis of the GASA genes in Chinese cabbage. In total, 15 GASA genes were identified in the Chinese cabbage genome, and the physicochemical property, subcellular location, and tertiary structure of the corresponding GASA proteins were elucidated. Phylogenetic analysis, conserved motif, and gene structure showed that the GASA proteins were divided into three well-conserved subfamilies. Synteny analysis proposed that the expansion of the GASA genes was influenced mainly by whole-genome duplication (WGD) and transposed duplication (TRD) and that duplication gene pairs were under negative selection. Cis-acting elements of the GASA promoters were involved in plant development, hormonal and stress responses. Expression profile analysis showed that the GASA genes were widely expressed in different tissues of Chinese cabbage, but their expression patterns appeared to diverse. The qRT-PCR analysis of nine GASA genes confirmed that they responded to salt stress, heat stress, and hormonal triggers. CONCLUSIONS Overall, this study provides a theoretical basis for further exploring the important role of the GASA gene family in the functional genome of Chinese cabbage.

Functional studies of four MiFPF genes in mango revealed their function in promoting flowering in transgenic Arabidopsis. JOURNAL OF PLANT PHYSIOLOGY 2023; 285:153994. [PMID: 37105044 DOI: 10.1016/j.jplph.2023.153994] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/03/2022] [Revised: 03/19/2023] [Accepted: 04/20/2023] [Indexed: 05/22/2023]
Abstract
Flowering promoting factor (FPF) genes play a substantial regulatory role in the process of flowering. In the present study, four MiFPF genes, namely, MiFPF1, MiFPF2, MiFPF3a, and MiFPF3b, were obtained from mango (Mangifera indica L.). Tissue expression analysis showed that MiFPFs were expressed in all mango tissues. Specifically, MiFPF1 and MiFPF2 were highly expressed in leaves, while MiFPF3a and MiFPF3b were highly expressed in flowers and buds. The four MiFPF proteins localize to the nucleus. Overexpression of MiFPFs in transgenic Arabidopsis resulted in early flowering and upregulated the expression of APETAL1 (AP1), FLOWERING LOCUS D (FD) and FLOWERING LOCUS T (FT). MiFPF genes increased the root growth of transgenic Arabidopsis plants under gibberellin treatment. BiFC assays showed that MiFPFs can interact with several DELLA proteins. Taken together, our results demonstrate that the MiFPF gene was involved not only in promoting flowering but also in increasing root growth under gibberellin (GA3) treatment.

Genome-Wide Identification, Evolutionary and Functional Analyses of WRKY Family Members in Ginkgo biloba. Genes (Basel) 2023; 14:genes14020343. [PMID: 36833270 PMCID: PMC9956969 DOI: 10.3390/genes14020343] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 01/07/2023] [Accepted: 01/26/2023] [Indexed: 01/31/2023] Open
Abstract
WRKY transcription factors (TFs) are one of the largest families in plants which play essential roles in plant growth and stress response. Ginkgo biloba is a living fossil that has remained essentially unchanged for more than 200 million years, and now has become widespread worldwide due to the medicinal active ingredients in its leaves. Here, 37 WRKY genes were identified, which were distributed randomly in nine chromosomes of G. biloba. Results of the phylogenetic analysis indicated that the GbWRKY could be divided into three groups. Furthermore, the expression patterns of GbWRKY genes were analyzed. Gene expression profiling and qRT-PCR revealed that different members of GbWRKY have different spatiotemporal expression patterns in different abiotic stresses. Most of the GbWRKY genes can respond to UV-B radiation, drought, high temperature and salt treatment. Meanwhile, all GbWRKY members performed phylogenetic tree analyses with the WRKY proteins of other species which were known to be associated with abiotic stress. The result suggested that GbWRKY may play a crucial role in regulating multiple stress tolerances. Additionally, GbWRKY13 and GbWRKY37 were all located in the nucleus, while GbWRKY15 was located in the nucleus and cytomembrane.

Transcriptomic and functional characterization reveals CsHAK5;3 as a key player in K + homeostasis in grafted cucumbers under saline conditions. PLANT SCIENCE : AN INTERNATIONAL JOURNAL OF EXPERIMENTAL PLANT BIOLOGY 2023; 326:111509.

Abstract
Grafting can improve the salt tolerance of many crops. However, critical genes in scions responsive to rootstock under salt stress remain a mystery. We found that pumpkin rootstock decreased the content of Na+ by 70.24 %, increased the content of K+ by 25.9 %, and increased the K+/Na+ ratio by 366.0 % in cucumber scion leaves. RNA-seq analysis showed that ion transport-related genes were the key genes involved in salt stress tolerance in grafted cucumber. The identification and analysis of the expression of K+ transporter proteins in cucumber and pumpkin revealed six and five HAK5 members, respectively. The expression of CsHAK5;3 in cucumber was elevated in different graft combinations under salt stress and most notably in cucumber scion/pumpkin rootstock. CsHAK5;3 was localized to the plasma membrane, and a yeast complementation assay revealed that it can transport K+. CsHAK5;3 knockout in hairy root mutants decreased the K+ content of leaves (45.6 %) and roots (50.3 %), increased the Na+ content of leaves (29.3 %) and roots (34.8 %), and decreased the K+/Na+ ratio of the leaves (57.9 %) and roots (62.9 %) in cucumber. However, CsHAK5;3 overexpression in hairy roots increased the K+ content of the leaves (31.2 %) and roots (38.3 %), decreased the Na+ content of leaves (17.2 %) and roots (14.3 %), and increased the K+/Na+ ratio of leaves (58.9 %) and roots (61.6 %) in cucumber. In conclusion, CsHAK5;3 in cucumber can mediate K+ transport and is one of the key target pumpkin genes that enhance salt tolerance of cucumber grafted.

Abstract
BACKGROUND Kelch repeat F-box (KFB) proteins play vital roles in the regulation of multitudinous biochemical and physiological processes in plants, including growth and development, stress response and secondary metabolism. Multiple KFBs have been characterized in various plant species, but the family members and functions have not been systematically identified and analyzed in potato. RESULTS Genome and transcriptome analyses of StKFB gene family were conducted to dissect the structure, evolution and function of the StKFBs in Solanum tuberosum L. Totally, 44 StKFB members were identified and were classified into 5 groups. The chromosomal localization analysis showed that the 44 StKFB genes were located on 12 chromosomes of potato. Among these genes, two pairs of genes (StKFB15/16 and StKFB40/41) were predicted to be tandemly duplicated genes, and one pair of genes (StKFB15/29) was segmentally duplicated genes. The syntenic analysis showed that the KFBs in potato were closely related to the KFBs in tomato and pepper. Expression profiles of the StKFBs in 13 different tissues and in potato plants with different treatments uncovered distinct spatial expression patterns of these genes and their potential roles in response to various stresses, respectively. Multiple StKFB genes were differentially expressed in yellow- (cultivar 'Jin-16'), red- (cultivar 'Red rose-2') and purple-fleshed (cultivar 'Xisen-8') potato tubers, suggesting that they may play important roles in the regulation of anthocyanin biosynthesis in potato. CONCLUSIONS This study reports the structure, evolution and expression characteristics of the KFB family in potato. These findings pave the way for further investigation of functional mechanisms of StKFBs, and also provide candidate genes for potato genetic improvement.

Abstract
The 14-3-3 proteins play essential roles in regulating various biological processes and abiotic stress responses in plants. However, there have been few studies of 14-3-3 family members in cucumber. Here, we identified a total of ten 14-3-3 genes (named as CsGF14a-j) in the cucumber genome. These genes are unevenly distributed across six cucumber chromosomes, and six of them were found to be segmentally duplicated. A phylogenetic analysis of 14-3-3 proteins in cucumber and other plant species showed that they could be divided into two distinct groups (ε and non-ε). Members in the same group tend to have similar exon-intron structure and conserved motif patterns. Several hormone-, stress- and development-related cis-elements associated with transcriptional regulation were found in the promoters of CsGF14 genes. RNA-seq data showed that most CsGF14 genes have broad expression in different tissues, and some had preferential expression in specific tissues and variable expression at certain developmental stages during fruit development. Quantitative real-time PCR (qRT-PCR) results revealed that nearly all tested CsGF14 genes were significantly up-regulated under cold and drought stress at certain time points. These results provide important information about the functions of CsGF14 genes in cucumber.
