Based on yeast one-hybrid assays, we show that the presence of C-terminal AHA motifs is not a prerequisite for transactivation potential in rice heat shock factors. Transcriptional activation or transactivation (TA) of heat stress responsive genes takes place by binding of heat shock factors (Hsfs) to heat shock elements. Analysis of TA potential of thirteen rice (Oryza sativa L.) Hsfs (OsHsfs) carried out in this study by yeast one-hybrid assay showed that OsHsfsA3 possesses strong TA potential while OsHsfs A1a, A2a, A2b, A4a, A4d, A5, A7b, B1, B2a, B2b, B2c and B4d lack TA potential...

Heterogeneous expression of the rice genes "fruit-weight 2.2-like" (OsFWL) affects Cd resistance in yeast, and OsFWL4 mediates the translocation of Cd from roots to shoots. Cadmium (Cd) induces chronic and toxic effects in humans. In a previous study (Xu et al. in Planta 238:643-655, 2013), we cloned the rice genes, designated OsFWL1-8, homologous to the tomato fruit-weight 2.2. Here, we show that expression of genes OsFWL3-7 in yeast confers resistance to Cd. The Cd contents of OsFWL3-, -4-, -6- and -7-transformed Cd(II)-sensitive yeast mutant ycf1 cells were strongly decreased compared with those of empty vector, with the strongest resistance to Cd observed in cells expressing OsFWL4...

Chinese sacbrood virus (CSBV) causes larval death and apiary collapse of Apis cerana. VP3 is a capsid protein of CSBV but its function is poorly understood. To determine the function of VP3 and screen for novel binding proteins that interact with VP3, we conducted yeast two-hybrid screening, glutathione S-transferase pull-down, and co-immunoprecipitation assays. Galectin (GAL) is a protein involved in immune regulation and host-pathogen interactions. The yeast two-hybrid screen implicated GAL as a major VP3-binding candidate...

Copine1 (CPNE1), has tandem C2 domains and an A domain. We previously demonstrated that CPNE1 directly induces neuronal differentiation via Protein kinase B (AKT) phosphorylation in the hippocampal progenitor cell line, HiB5. To better understand its cellular function, we carried out a yeast two-hybrid screening to find CPNE1 binding partners. Among the identified proteins, Jun activation domain-binding protein 1 (JAB1) appears to directly interact with CPNE1. Between CPNE1 and JAB1, the physical interaction was confirmed in vitro and in vivo...

Bombyx mori nucleopolyhedrovirus (BmNPV) is the most important pathogen of Bombyx mori, silkworm and causes severe losses in the silk industry. During the virus infectious cycle, budded virus (BVs) and occlusion-derived virus (ODVs) particles, which have identical genetic content but different phenotypes, are produced. The envelope glycoprotein GP64, specific in BVs, is involved in host cell receptor binding and is sufficient to mediate membrane fusion during the viral entry. However, the host cell factors, interacting with GP64 to mediate BVs infection, are still unknown...

Fibroblast growth factor 21 (FGF21) as a member of the FGFs serves a key role in glucose homeostasis and protection of the liver, heart, kidney and skin from damage as well as cancer cell development. In addition, transcription of FGF21 is sensitive to diverse damages; however, the role of the transcriptional regulator of FGF21 in cancer cells remains to be elucidated. FGFs were identified to have dominant expression in cancer cells; therefore, mouse forestomach carcinoma (MFC) cells were used in the present study, which is a mouse stomach cancer cell strain for identifying the FGF21 regulators...

Peach is an ideal species for fruit tree research because of its small, fully sequenced genome. Chloroplast development is dependent on the tight cooperation between the nuclear and plastid genomes, and is regulated by GLK transcription factors. In this work, the pigment content was monitored and the chloroplast-to-chromoplast conversion during the fruit ripening was visualized by transmission electron microscopy. Localization and expression analyses showed that PpGLK1 was located in the nucleus and expressed mainly in the leaves and fruit skin...

Bud dormancy release is regulated by gibberellins (GAs). DELLA proteins are highly conserved and act as negative regulators in GA signaling pathway. The present study established a relationship between PmRGL2 in Japanese apricot and GA4 levels during dormancy release of floral buds. Overexpression of PmRGL2 in poplar delayed the onset of bud dormancy and resulted in dwarf plants, relative to wild-type trees. PmRGL2 exhibited higher expression during ecodormancy and relatively lower expression during endodormancy...

N-Acetylgalactosaminyltransferase-14 (GALNT14) is a member of acetylgalactosaminyltransferases family. We have shown that GALNT14 could promote breast cancer cell invasion. However, the underlying molecular mechanism is unclear. Here, using yeast two hybrid, we find that EGF-containing fibulin-like extracellular matrix protein 2 (EFEMP2) interacts with GALNT14. Both in vitro and in vivo binding assays show that EFEMP2 is associated with GALNT14. Moreover, we find that GALNT14 mediates glycosylation of EFEMP2...

In eukaryotes, the ubiquitin-like (UBL) protein-activating enzymes play a crucial role in autophagy process, however, it is poorly characterized in filamentous fungi. Here, we investigated the functions of two UBL activating enzymes, BcAtg3 (E2) and BcAtg7 (E1) in the plant pathogenic fungus Botrytis cinerea. The physical interaction of BcAtg3 with BcAtg7 was demonstrated by yeast two-hybrid system. Subcellular localization assays showed that BcAtg3 diffused in cytoplasm, and BcAtg7 localized in cytoplasm as pre-autophagosomal structures (PAS)...

A novel salt overly-sensitive 2 (SOS2) interaction protein was identified by yeast two hybrid (Y2H) library and was referred to as SOS2 interaction protein 1 (SIP1). SIP1 belongs to a plant-specific protein family, which contains a conserved domain that corresponds to a putative N-acetyltransferase. The members of this family are tolerant to heavy metals and oxidative stress. Here, SIP1 was identified as a salt-responsive gene. The sos2×sip1-1 double mutant was more sensitive than the sos2 single mutant upon salt stress, whereas the overexpression of SIP1 gene enhanced the plant salt tolerance, suggesting that SIP1 was involved in plant salt tolerance...

DNA J HOMOLOG 3 (J3) is a special transcriptional regulator in flowering time control, but the molecular mechanism of J3 in regulating flowering time has not been thoroughly revealed in B. juncea which is one important oilseed and vegetable crop. In this study, J3 gene was cloned from B. juncea (BjuJ3). Phylogenetic relationship analysis showed that the BjuJ3 had high amino acid sequence similarity (>93%) with other Brassica plants. The BjuJ3-transgenic tobacco plants exhibited early flowering, suggesting that BjuJ3 was an activator of flowering time...

Jasmonates (JAs) are plant hormones that induce many secondary metabolites accumulation, such as rutin in buckwheat, via regulation of JAs-responsive transcription factors (TFs). Here, we report on the identification of a clade of JAs-responsive subgroup 4 MYB TFs, FtMYB13, FtMYB14, FtMYB15 and FtMYB16, directly repressing rutin biosynthesis in Fagopyrum tataricum. Immunoblot analysis showed that FtMYB13, FtMYB14 and FtMYB15 could be degraded via 26S proteasome in COI1-dependent JA signaling pathway, and this degradation is due to the SID motif in their C-terminus...

In many eukaryotes, transcription factor MCM1 gene plays crucial roles in regulating mating processes and pathogenesis by interacting with other co-factors. However, little is known about the role of MCM1 in rust fungi. Here, we identified two MCM1 orthologs, PstMCM1-1 and PstMCM1-2, in the stripe rust pathogen Puccinia striiformis f. sp. tritici (Pst). Sequence analysis indicated that both PstMCM1-1 and PstMCM1-2 contain conserved MADS domains and that PstMCM1-1 belongs to a group of SRF-like proteins that are evolutionarily specific to rust fungi...

BACKGROUND: Chicken coccidiosis, a disease caused by seven species of Eimeria (Apicomplexa: Coccidia), inflicts severe economic losses on the poultry industry. Eimeria tenella is the one of the most virulent species pathogenic to chickens. Many parasitic protozoans are parasitised by double-stranded (ds) RNA viruses, and the influence of protozoan viruses on parasitic protozoans has been extensively reported. E. tenella RNA virus 1 (Etv) was identified in E. tenella, and the complete genome sequence of Etv was analysed...

DIVARICATA AND RADIALIS INTERACTING FACTOR (DRIF) from snapdragon (Antirrhinum majus) is a MYB/SANT protein that interacts with related MYB/SANT proteins, RADIALIS and DIVARICATA, through its N-terminal MYB/SANT domain. In addition to the MYB/SANT domain, DRIF contains a C-terminal Domain of Unknown Function (DUF3755). Here we describe novel protein-protein interactions involving a poplar (Populus trichocarpa) homolog of DRIF, PtrDRIF1. In addition to interacting with poplar homologs of RADIALIS (PtrRAD1) and DIVARICATA (PtrDIV4), PtrDRIF1 interacted with members of other families within the homeodomain-like superfamily, including PtrWOX13c, a WUSCHEL-RELATED HOMEOBOX protein, and PtrKNAT7, a KNOTTED1-LIKE HOMEOBOX protein...

Mutations mimicking growth factor-induced proliferation and motility characterize aggressive subtypes of mammary tumors. To unravel currently unknown players in these processes, we performed phosphoproteomic analysis on untransformed mammary epithelial cells (MCF10A) that were stimulated in culture with epidermal growth factor (EGF). We identified ladinin-1 (LAD1), a largely uncharacterized protein to date, as a phosphorylation-regulated mediator of the EGF-to-ERK pathway. Further experiments revealed that LAD1 mediated the proliferation and migration of mammary cells...

Mitogen-activated protein kinase (MAPK) cascades play a central role in cellular growth, proliferation and survival. MAPK cascade genes have been extensively investigated in model plants, mammals, yeast and fungi, but are not characterized in Plasmodiophora brassicae, which causes clubroot disease in cruciferous plants. Here, we identified 7 PbMAPK, 3 PbMAPKK and 9 PbMAPKKK genes in the P. brassicae genome. Transcriptional profiling analysis demonstrated that several MAPK, MAPKK and MAPKKK genes were preferentially expressed in three different zoosporic stages...

Interferon-γ (IFN-γ) represents one of the most important innate immunity responses in a host to combat infections of many human viruses including human herpesviruses. Human N-myc interactor (Nmi) protein, which has been shown to interact with signal transducer and activator of transcription (STAT) proteins including STAT1, is important for the activation of IFN-γ induced STAT1-dependent transcription of many genes responsible for IFN-γ immune responses. However, no proteins encoded by herpesviruses have been reported to interact with Nmi and inhibit Nmi-mediated activation of IFN-γ immune responses to achieve immune evasion from IFN-γ responses...
