Genome-wide investigation of calcium-dependent protein kinase gene family in pineapple: evolution and expression profiles during development and stress. BMC Genomics 2020; 21:72. [PMID: 31973690 PMCID: PMC6979071 DOI: 10.1186/s12864-020-6501-8] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2019] [Accepted: 01/16/2020] [Indexed: 11/25/2022] Open
Abstract
Background Calcium-dependent protein kinase (CPK) is one of the main Ca2+ combined protein kinase that play significant roles in plant growth, development and response to multiple stresses. Despite an important member of the stress responsive gene family, little is known about the evolutionary history and expression patterns of CPK genes in pineapple. Results Herein, we identified and characterized 17 AcoCPK genes from pineapple genome, which were unevenly distributed across eight chromosomes. Based on the gene structure and phylogenetic tree analyses, AcoCPKs were divided into four groups with conserved domain. Synteny analysis identified 7 segmental duplication events of AcoCPKs and 5 syntenic blocks of CPK genes between pineapple and Arabidopsis, and 8 between pineapple and rice. Expression pattern of different tissues and development stages suggested that several genes are involved in the functional development of plants. Different expression levels under various abiotic stresses also indicated that the CPK family underwent functional divergence during long-term evolution. AcoCPK1, AcoCPK3 and AcoCPK6, which were repressed by the abiotic stresses, were shown to be function in regulating pathogen resistance. Conclusions 17 AcoCPK genes from pineapple genome were identified. Our analyses provide an important foundation for understanding the potential roles of AcoCPKs in regulating pineapple response to biotic and abiotic stresses

Abstract
The mitogen-activated protein kinase (MAPK) cascade, which is a major signal transduction pathway widely distributed in eukaryotes, has an important function in plant development and stress responses. However, less information is known regarding the MAPKKK and MAPKK gene families in the important fruit crop banana. In this study, 10 MAPKK and 77 MAPKKK genes were identified in the banana genome, and were classified into 4 and 3 subfamilies respectively based on phylogenetic analysis. Majority of MAPKKK and MAPKK genes in the same subfamily shared similar gene structures and conserved motifs. The comprehensive transcriptome analysis indicated that MAPKKK-MAPKK genes is involved in tissue development, fruit development and ripening, and response to abiotic stress of drought, cold and salt in two banana genotypes. Interaction networks and co-expression assays demonstrated that MAPK signaling cascade mediated network participates in multiple stress signaling, which was strongly activated in Fen Jiao (FJ). The findings of this study advance understanding of the intricately transcriptional control of MAPKKK-MAPKK genes and provide robust candidate genes for further genetic improvement of banana.

JOURNAL OF PLANT PHYSIOLOGY 2015; 185:1-12. [PMID: 26264965 DOI: 10.1016/j.jplph.2015.05.020] [Citation(s) in RCA: 47] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/22/2015] [Revised: 05/29/2015] [Accepted: 05/31/2015] [Indexed: 05/20/2023]
Abstract
Abiotic stresses, such as drought, salinity, cold and heat, are major environmental factors that limit crop productivity. Vitis amurensis Rupr. is a wild grapevine species displaying a high level of abiotic and biotic stress resistance. Protein kinases, including Ca(2+)-dependent protein kinases (CDPKs), are known to mediate plant acclimation to various environmental changes. However, the functions of most grape CDPKs have not been clarified. A recent CDPK gene expression analysis revealed that 10 CDPK genes of V. amurensis were up-regulated under different abiotic stress treatments. The expression of the VaCPK20 gene was significantly up-regulated under low and high temperature stress in V. amurensis. In the current study, the effects of overexpressing the VaCPK20 gene in callus cell lines of V. amurensis and transgenic plants of A. thaliana on their responses to abiotic stresses were investigated. Transgenic Arabidopsis overexpressing the VaCPK20 gene showed higher tolerance to freezing and drought stresses, and transgenic grape cell cultures overexpressing the VaCPK20 gene showed higher resistance to cold stress in comparison with the controls transformed by the "empty" vector. Heat and salt stress resistance of the transgenic V. amurensis calli and A. thaliana was comparable to that of the wild type and vector controls. Overexpression of the VaCPK20 gene increased the expression of stress-responsive genes, such as COR47, NHX1, KIN1, or ABF3, in the transgenic Arabidopsis plants under non-stress conditions, after freezing, and under drought stress. The results imply that VaCPK20 may act as a regulatory factor involved in cold and drought stress response pathways.

Abstract
As Ca2+ sensors and effectors, calcium-dependent protein kinases (CDPKs) play important roles in plant growth, development, and response to environmental cues. However, no CDPKs have been characterized in Capsicum annuum thus far. Herein, a genome wide comprehensive analysis of genes encoding CDPKs and CDPK-related protein kinases (CRKs) was performed in pepper, a total of 31 CDPK genes and five closely related kinase genes were identified, which were phylogenetically divided into four distinct subfamilies and unevenly distributed across nine chromosomes. Conserved sequence and exon-intron structures were found to be shared by pepper CDPKs within the same subfamily, and the expansion of the CDPK family in pepper was found to be due to segmental duplication events. Five CDPKs in the C. annuum variety CM334 were found to be mutated in the Chiltepin variety, and one CDPK present in CM334 was lost in Chiltepin. The majority of CDPK and CRK genes were expressed in different pepper tissues and developmental stages, and 10, 12, and 8 CDPK genes were transcriptionally modified by salt, heat, and Ralstonia solanacearum stresses, respectively. Furthermore, these genes were found to respond specifically to one stress as well as respond synergistically to two stresses or three stresses, suggesting that these CDPK genes might be involved in the specific or synergistic response of pepper to salt, heat, and R. solanacearum. Our results lay the foundation for future functional characterization of pepper CDPK and its closely related gene families.

JOURNAL OF PLANT PHYSIOLOGY 2013; 170:1491-500.

Abstract
Calcium-dependent protein kinases (CDPKs), which are important sensors of Ca(2+) flux in plants, are known to play essential roles in plant development and adaptation to abiotic stresses. In the present work, we studied expression of CDPK genes under osmotic and temperature stress treatments in wild-growing grapevine Vitis amurensis Rupr., which is known to possess high adaptive potential and a high level of resistance against adverse environmental conditions. In this study, using RT-PCR with degenerate primers, DNA sequencing and frequency analysis of RT-PCR products, we identified 13 CDPK genes that are actively expressed in healthy V. amurensis cuttings under high salt, high mannitol, desiccation, and temperature stress conditions. 12 CDPKs, namely VaCPK1, VaCPK2, VaCPK3, VaCPK9, VaCPK13, VaCPK16, VaCPK20, VaCPK21, VaCPK25, VaCPK26, VaCPK29 and VaCPK30, were novel for Vitaceae, and their full cDNAs were obtained and described. Quantitative real-time RT-PCR demonstrated that mRNA levels of 10 VaCPK genes were differentially up-regulated under the osmotic and temperature stress treatments, while the abundance of 3 VaCPK transcript variants, VaCPK3a, VaCPK25, and VaCPK30, was not markedly changed. Expression profiling of the VaCPK genes in leaves, leaf petioles, stems, inflorescences, berries, and seeds of V. amurensis revealed that the genes exhibit different organ-specific expression patterns. The stimulatory effect of abiotic stress on the expression of the VaCPK1, 2, 3, 9, 13, 16, 20, 21, 26, and VaCPK29 genes is suggestive of their implication in the grapevine response to osmotic and temperature stresses, while the variability in their organ-specific expression patterns indicates that the enzymes perform distinct biological functions.

Abstract
Fungal endophytes have been isolated from almost every plant, infecting their hosts without causing visible disease symptoms, and yet have still proved to be involved in plant secondary metabolites accumulation. To decipher the possible physiological mechanisms of the endophytic fungus-host interaction, the role of protein phosphorylation and the relationship between endophytic fungus-induced kinase activity and nitric oxide (NO) and brassinolide (BL) in endophyte-enhanced volatile oil accumulation in Atractylodes lancea plantlets were investigated using pharmacological and biochemical approaches. Inoculation with the endophytic fungus Gilmaniella sp. AL12 enhanced the activities of total protein phosphorylation, Ca²⁺-dependent protein kinase, and volatile oil accumulation in A. lancea plantlets. The upregulation of protein kinase activity could be blocked by the BL inhibitor brassinazole. Furthermore, pretreatments with the NO-specific scavenger cPTIO significantly reduced the increased activities of protein kinases in A. lancea plantlets inoculated with endophytic fungus. Pretreatments with different protein kinase inhibitors also reduced fungus-induced NO production and volatile oil accumulation, but had barely no effect on the BL level. These data suggest that protein phosphorylation is required for endophyte-induced volatile oil production in A. lancea plantlets, and that crosstalk between protein phosphorylation and the NO pathway may occur and act as a downstream signaling event of the BL pathway.

Abstract
KEY MESSAGE : VaCDPK3a is actively expressed in leaves, stems, inflorescences, and berries of Vitis amurensis and may act as a positive growth regulator, but is not involved in the regulation of resveratrol biosynthesis. Calcium-dependent protein kinases (CDPKs) are known to play important roles in plant development and defense against biotic and abiotic stresses. It has previously been shown that CDPK3a is the predominant CDPK transcript in cell cultures of wild-growing grapevine Vitis amurensis Rupr., which is known to possess high resistance against environmental stresses and to produce resveratrol, a polyphenol with valuable pharmacological effects. In this study, we aimed to define the full cDNA sequence of VaCDPK3a and analyze its organ-specific expression, responses to plant hormones, temperature stress and exogenous NaCl, and the effects of VaCDPK3a overexpression on biomass accumulation and resveratrol content in V. amurensis calli. VaCDPK3a was actively expressed in all analyzed V. amurensis organs and tissues and was not transcriptionally regulated by salt and temperature stresses. The highest VaCDPK3a expression was detected in young leaves and the lowest in stems. A reduction in the VaCDPK3a expression correlated with a lower rate of biomass accumulation and higher resveratrol content in calli of V. amurensis under different growth conditions. Overexpression of the VaCDPK3a gene in the V. amurensis calli significantly increased cell growth for a short period of time but did not have an effect on resveratrol production. Further subculturing of the transformed calli resulted in cell death and a decrease in expression of the endogenous VaCDPK3a. The data suggest that while VaCDPK3a acts as a positive regulator of V. amurensis cell growth, it is not involved in the signaling pathway regulating resveratrol biosynthesis and resistance to salt and temperature stresses.

Abstract
1-Aminocyclopropane-1-carboxylic acid synthase (ACS) catalyzes the rate-limiting step in ethylene biosynthesis during ripening. ACS isozymes are regulated both transcriptionally and post-translationally. However, in banana, an important climacteric fruit, little is known about post-translational regulation of ACS. Here, we report the post-translational modification of MA-ACS1 (Musa acuminata ACS1), a ripening inducible isozyme in the ACS family, which plays a key role in ethylene biosynthesis during banana fruit ripening. Immunoprecipitation analyses of phospholabeled protein extracts from banana fruit using affinity-purified anti-MA-ACS1 antibody have revealed phosphorylation of MA-ACS1, particularly in ripe fruit tissue. We have identified the induction of a 41-kDa protein kinase activity in pulp at the onset of ripening. The 41-kDa protein kinase has been identified as a putative protein kinase by MALDI-TOF/MS analysis. Biochemical analyses using partially purified protein kinase fraction from banana fruit have identified the protein kinase as a Ser/Thr family of protein kinase and its possible involvement in MA-ACS1 phosphorylation during ripening. In vitro phosphorylation analyses using synthetic peptides and site-directed mutagenized recombinant MA-ACS1 have revealed that serine 476 and 479 residues at the C-terminal region of MA-ACS1 are phosphorylated. Overall, this study provides important novel evidence for in vivo phosphorylation of MA-ACS1 at the molecular level as a possible mechanism of post-translational regulation of this key regulatory protein in ethylene signaling pathway in banana fruit during ripening.

Abstract
Plant mitogen-activated protein kinase (MAPK) cascades are involved in a range of biotic and abiotic stress responses, but many members of the MAPK family involved in signal transduction of the stress-related hormone ABA remain to be identified and how they regulate ABA signaling is still unclear. Here we characterized biochemically an apple MAPK signaling cascade MdMKK1-MdMPK1, which is transiently activated by ABA. Expression of MdMKK1 or MdMPK1 in the reference plant Arabidopsis (Arabidopsis thaliana) confers ABA hypersensitivity in both seed germination and seedling growth, showing that MdMKK1 and MdMPK1 are positively involved in ABA signaling. Expression of MdMKK1 or MdMPK1 up-regulates expression of several ABA-responsive transcription factor-encoding genes including ABI5. Furthermore, MdMPK1 phosphorylates the Arabidopsis ABI5 protein through the unique residue Ser314, showing that ABI5 is a potential direct downstream component of MAPK in ABA signaling. These findings indicate that the apple MdMKK1-MdMPK1-coupled signaling cascade may function in ABA signaling by regulating both expression and the phosphorylation status of the important ABA signaling component ABI5 or ABI5-like transcription factors.

Abstract
Using pharmacological and biochemical approaches, the role of protein phosphorylation and the interrelationship between water stress-enhanced kinase activity, antioxidant enzyme activity, hydrogen peroxide (H2O2) accumulation and endogenous abscisic acid in maize (Zea mays L.) leaves were investigated. Water-stress upregulated the activities of total protein phosphorylation and Ca2+-dependent protein kinase, and the upregulation was blocked in abscisic acid-deficient vp5 mutant. Furthermore, pretreatments with a nicotinamide adenine dinucleotide phosphate oxidase inhibitor and a scavenger of H2O2 significantly reduced the increased activities of total protein kinase and Ca2+-dependent protein kinase in maize leaves exposed to water stress. Pretreatments with different protein kinase inhibitors also reduced the water stress-induced H2O2 production and the water stress-enhanced activities of antioxidant enzymes such as superoxide dismutase, catalase, ascorbate peroxidase and glutathione reductase. The data suggest that protein phosphorylation and H2O2 generation are required for water stress-induced antioxidant defense in maize leaves and that crosstalk between protein phosphorylation and H2O2 generation may occur.

Abstract
NAD(+)-dependent sorbitol dehydrogenase (NAD-SDH, EC 1.1.1.14), a key enzyme in sorbitol metabolism, plays an important role in regulating sink strength and determining the quality of apple fruit. Understanding the tissue and subcellular localization of NAD-SDH is helpful for understanding sorbitol metabolism in the apple. In this study, two NAD-SDH cDNA sequences were isolated from apple fruits (Malus domestica Borkh cv. Starkrimson) and named MdSDH5 and MdSDH6. Immunohistochemical analysis revealed that NAD-SDH is distributed in both the flesh and the vascular tissue of the fruit, and the vascular tissue and mesophyll tissue in the young and old leaves, indicating that it is a ubiquitous protein expressed in both sink and source organs. Immunogold electron microscopy analysis demonstrated that NAD-SDH is localized mainly in the cytoplasm and chloroplast of the fruit and leaves. The chloroplast localization of NAD-SDH was confirmed by the transient expression of MdSDH5-GFP and MdSDH6-GFP in the mesophyll protoplast of Arabidopsis. NAD-SDH was also found in electron opaque deposits of vacuoles in young and mature leaves. These data show that NAD-SDH has different subcellular localizations in fruit and leaves, indicating that it might play a different role in sorbitol metabolism in different tissues of apple.

Abstract
Calcium-dependent protein kinase (CDPK) activities were detected both in the soluble and the membrane fraction of various tomato (Lycopersicon esculentum Mill.) organs, using a synthetic peptide mimicking the serine 11 phosphorylation site of a tomato sucrose synthase (SS, EC 2.4.1.13) isoform as substrate. The levels of membrane and soluble Ser-CDPK activities were differentially regulated during fruit development. The membrane Ser-CDPK activity was maximal in young fruit but decreased as the fruit developed, suggesting a specific role during fruit growth. Using an in gel assay with purified tomato SS as substrate, we showed that partially purified soluble and membrane Ser-CDPK preparations both contained a SS-kinase polypeptide of 55 kDa. The membrane and soluble Ser-CDPK activities were largely inactivated in the absence of calcium or when MgCl(2) was replaced by MnCl(2). Both soluble and membrane Ser-CDPK activities were very sensitive to staurosporine. Using Fe(III)-immobilized metal chromatography to determine the apparent phosphorylation status of the enzyme in vivo, we showed that soluble SS was largely dephosphorylated in fruits fed EGTA or staurosporine, compared to fruits fed water or sucrose. Moreover, the level of SS increased by about two-fold in the membrane fraction of fruits fed the Ser-CDPK inhibitors, compared to the control. The level of SS protein in the membrane and soluble fractions of tomato fruit was developmentally regulated, the membrane form being specifically detected in actively growing fruits. Together, our results suggest that a mechanism involving protein phosphorylation/dephosphorylation and/or calcium would in part control the association of SS isoforms with membranes in developing tomato fruit.

Abstract
It has been demonstrated that calcium plays a central role in mediating abscisic acid (ABA) signaling, but many of the Ca2+-binding sensory proteins as the components of the ABA-signaling pathway remain to be elucidated. Here we identified, characterized, and purified a 58-kD ABA-stimulated calcium-dependent protein kinase from the mesocarp of grape berries (Vitis vinifera x Vitis labrusca), designated ACPK1 (for ABA-stimulated calcium-dependent protein kinase1). ABA stimulates ACPK1 in a dose-dependent manner, and the ACPK1 expression and enzyme activities alter accordantly with the endogenous ABA concentrations during fruit development. The ABA-induced ACPK1 stimulation appears to be transient with a rapid effect in 15 min but also with a slow and steady state of induction after 60 min. ABA acts on ACPK1 indirectly and dependently on in vivo state of the tissues. Two inactive ABA isomers, (-)-2-cis, 4-trans-ABA and 2-trans, 4-trans-(+/-)-ABA, are ineffective for inducing ACPK1 stimulation, revealing that the ABA-induced effect is stereo specific to physiological active (+)-2-cis, 4-trans-ABA. The other phytohormones such as auxin indoleacetic acid, gibberellic acid, synthetic cytokinin N-benzyl-6-aminopurine, and brassinolide are also ineffective in this ACPK1 stimulation. Based on sequencing of the two-dimensional electrophoresis-purified ACPK1, we cloned the ACPK1 gene. The ACPK1 is expressed specifically in grape berry covering a fleshy portion and seeds, and in a developmental stage-dependent manner. We further showed that ACPK1 is localized in both plasma membranes and chloroplasts/plastids and positively regulates plasma membrane H+-ATPase in vitro, suggesting that ACPK1 may be involved in the ABA-signaling pathway.
