Fox Genes

The forkhead box (Fox) gene family, one of the most important families of transcription factors, participates in various biological processes. However, Fox genes in Hymenoptera are still poorly known. In this study, 14 Fox genes were identified in the genome of Apis cerana. In addition, 16 (Apis mellifera), 13 (Apis dorsata), 16 (Apis florea), 17 (Bombus terrestris), 16 (Bombus impatiens), and 18 (Megachile rotundata) Fox genes were identified in their genomes, respectively. Phylogenetic analyses suggest that FoxA is absent in the genome of A. dorsata genome. Similarly, FoxG is missing in the genomes A. cerana and A. dorsata. Temporal expression profiles obtained by quantitative real-time PCR revealed that Fox genes have distinct expression patterns in A. cerana, especially for three genes ACSNU03719T0 (AcFoxN4), ACSNU05765T0 (AcFoxB), and ACSNU07465T0 (AcFoxL2), which displayed high expression at the egg stage. Tissue expression patterns showed that FoxJ1 is significantly higher in the antennae of A. cerana and A. mellifera compared to other tissues. These results may facilitate a better understanding of the potential physiological functions of the Fox gene family in A. cerana and provide valuable information for a comprehensive functional analysis of the Fox gene family in Hymenopterans.

Abstract Background Caffeic acid O-methyltransferases (COMTs) play an important role in the diversification of natural products, especially in the phenylalanine metabolic pathway of plant. The content of COMT genes in blueberry and relationship between their expression patterns and the lignin content during fruit development have not clearly investigated by now. Results Ninety-two VcCOMTs were identified in Vaccinium corymbosum. According to phylogenetic analyses, the 92 VcCOMTs were divided into 2 groups. The gene structure and conserved motifs within groups were similar which supported the reliability of the phylogenetic structure groupings. Dispersed duplication (DSD) and whole-genome duplication (WGD) were determined to be the major forces in VcCOMTs evolution. The results showed that the results of qRT-PCR and lignin content for 22 VcCOMTs, VcCOMT40 and VcCOMT92 were related to lignin content at different stages of fruit development of blueberry. Conclusion We identified COMT gene family in blueberry, and performed comparative analyses of the phylogenetic relationships in the 15 species of land plant, and gene duplication patterns of COMT genes in 5 of the 15 species. We found 2 VcCOMTs were highly expressed and their relative contents were similar to the variation trend of lignin content during the development of blueberry fruit. These results provide a clue for further study on the roles of VcCOMTs in the development of blueberry fruit and could promisingly be foundations for breeding blueberry clutivals with higher fruit firmness and longer shelf life.

The SnRK gene family is a key regulator playing an important role in plant stress response by phosphorylating the target protein to regulate the signalling pathways. The function of SnRK gene family has been reported in many species but is limited to Triticum asetivum. In this study, SnRK gene family in the wheat genome was identified and its structural characteristics were described. One hundred forty-seven SnRK genes distributed across 21 chromosomes were identified in the Triticum aestivum genome and categorised into three subgroups (SnRK1/2/3) based on phylogenetic analyses and domain types. The gene intron-exon structure and protein-motif composition of SnRKs were similar within each subgroup but different amongst the groups. Gene duplication between the wheat, Arabidopsis, rice and barley genomes was also investigated in order to get insight into the evolutionary aspects of the TaSnRK family genes. SnRK genes showed differential expression patterns in leaves, roots, spike, and grains. Redundant stress-related cis-elements were also found in the promoters of 129 SnRK genes and their expression levels varied widely following drought, ABA and light regulated elements. In particular, TaSnRK2.11 had higher and increased expression under the abiotic stresses and can be a candidate gene for the abiotc stress tolerance. The findings will aid in the functional characterization of TaSnRK genes for further research.

Heavy-metal ATPase (HMA), an ancient family of transition metal pumps, plays important roles in the transmembrane transport of transition metals such as Cu, Zn, Cd, and Co. Although characterization of HMAs has been conducted in several plants, scarcely knowledge was revealed in Sedum plumbizincicola, a type of cadmium (Cd) hyperaccumulator found in Zhejiang, China. In this study, we first carried out research on genome-wide analysis of the HMA gene family in S. plumbizincicola and finally identified 8 SpHMA genes and divided them into two subfamilies according to sequence alignment and phylogenetic analysis. In addition, a structural analysis showed that SpHMAs were relatively conserved during evolution. All of the SpHMAs contained the HMA domain and the highly conserved motifs, such as DKTGT, GDGxNDxP, PxxK S/TGE, HP, and CPx/SPC. A promoter analysis showed that the majority of the SpHMA genes had cis-acting elements related to the abiotic stress response. The expression profiles showed that most SpHMAs exhibited tissue expression specificity and their expression can be regulated by different heavy metal stress. The members of Zn/Co/Cd/Pb subgroup (SpHMA1-3) were verified to be upregulated in various tissues when exposed to CdCl2. Here we also found that the expression of SpHMA7, which belonged to the Cu/Ag subgroup, had an upregulated trend in Cd stress. Overexpression of SpHMA7 in transgenic yeast indicated an improved sensitivity to Cd. These results provide insights into the evolutionary processes and potential functions of the HMA gene family in S. plumbizincicola, laying a theoretical basis for further studies on figuring out their roles in regulating plant responses to biotic/abiotic stresses.

AbstractMultidrug and toxic compound extrusion (MATE) proteins are involved in many physiological functions of plant growth and development. Although an increasing number of MATE proteins have been identified, the understanding of MATE proteins is still very limited in rice. In this study, 46 MATE proteins were identified from the rice (Oryza sativa) genome by homology searches and domain prediction. The rice MATE family was divided into four subfamilies based on the phylogenetic tree. Tandem repeats and fragment replication contribute to the expansion of the rice MATE gene family. Gene structure and cis-regulatory elements reveal the potential functions of MATE genes. Analysis of gene expression showed that most of MATE genes were constitutively expressed and the expression patterns of genes in different tissues were analyzed using RNA-seq. Furthermore, qRT-PCR-based analysis showed differential expression patterns in response to salt and drought stress. The analysis results of this study provide comprehensive information on the MATE gene family in rice and will aid in understanding the functional divergence of MATE genes.

Leucine-rich repeat receptor-like kinases (LRR-RLKs) make up the largest group of RLKs in plants and play important roles in many key biological processes such as pathogen response and signal transduction. To date, most studies on LRR-RLKs have been conducted on model plants. Here, we identified 236 and 230LRR-RLKsin two industrial oil-producing trees:Vernicia fordiiandVernicia montana, respectively. Sequence alignment analyses showed that the homology of the RLK domain (23.81%) was greater than that of the LRR domain (9.51%) among theVf/VmLRR-RLKs. The conserved motif of the LRR domain inVf/VmLRR-RLKsmatched well the known plant LRR consensus sequence but differed at the third last amino acid (W or L). Phylogenetic analysis revealed thatVf/VmLRR-RLKswere grouped into 16 subclades. We characterized the expression profiles ofVf/VmLRR-RLKsin various tissue types including root, leaf, petal, and kernel. Further investigation revealed thatVf/VmLRR-RLKorthologous genes mainly showed similar expression patterns in response to tree wilt disease, except 4 pairs ofVf/VmLRR-RLKsthat showed opposite expression trends. These results represent an extensive evaluation ofLRR-RLKsin two industrial oil trees and will be useful for further functional studies on these proteins.

Abstract Background: UDP-glucuronate decarboxylase (UXS) is an enzyme in plants and participates in cell wall noncellulose. Previous research suggested that cotton GhUXS gene regulated the conversion of non-cellulosic polysaccharides and modulates their composition in plant cell walls, showing its possible cellular function determining the quality of cotton fibers. Here, we performed evolutionary, phylogenetic, and expressional analysis of UXS genes from cottons and other selected plants. Results: By exploring the sequenced cotton genomes, we identified 10, 10, 18, and 20 UXSs genes in Gossypium raimondii , Gossypium arboretum , Gossypium hirsutum and Gossypium barbadense , and retrieved their homologs from other representative plants, including 5 dicots, 1 monocot, 5 green alga, 1 moss, and 1 lycophyte. Phylogenetic analysis suggested that UXS genes could be divided into four subgroups and members within each subgroup shared similar exon-intron structures, motif and subcellular location. Notably, gene colinearity information indicates 100% constructed trees to have aberrant topology, and helps determine and use corrected phylogeny. In spite of conservative nature of UXS, during the evolution of Gossypium , UXS genes were subjected to significant positive selection on key evolutionary nodes. Expression profiles derived from RNA-seq data showed distinct expression patterns of GhUXS genes in various tissues and different development. Most of GhUXS gene expressed highly at 10, 20 and 25 DPA (day post anthesis) of fibers. Real-time quantitative PCR analysis GhUXS genes expressed highly at 20 DPA or 25 DPA. Conclusions: UXS is relatively conserved in plants and significant positive selection affects cotton UXS evolution. The comparative genome-wide identification and expression profiling would lay an important foundation to understanding the biological functions of UXS gene family in cotton species and other plants.

Background The YABBY gene family is a family of small zinc finger transcription factors associated with plant morphogenesis, growth, and development. In particular, it is closely related to the development of polarity in the lateral organs of plants. Despite being studied extensively in many plant species, there is little information on genome-wide characterization of this gene family in Moso bamboo. Methods In the present study, we identified 16 PeYABBY genes, which were unequally distributed on 11 chromosomes, through genome-wide analysis of high-quality genome sequences of M oso bamboo by bioinformatics tools and biotechnological tools. Gene expression under hormone stress conditions was verified by quantitative real-time PCR (qRT-PCR) experiments. Results Based on peptide sequences and similarity of exon-intron structures, we classified the PeYABBY genes into four subfamilies. Analysis of putative cis-acting elements in promoters of these genes revealed that PeYABBYs contained a large number of hormone-responsive and stress-responsive elements. Expression analysis showed that they were expressed at a high level in Moso bamboo panicles, rhizomes, and leaves. Expression patterns of putative PeYABBY genes in different organs and hormone-treated were analyzed using RNA-seq data, results showed that some PeYABBY genes were responsive to gibberellin (GA) and abscisic acid (ABA), indicating that they may play an important role in plant hormone responses. Gene Ontology (GO) analyses of YABBY proteins indicated that they may be involved in many developmental processes, particularly high level of enrichment seen in plant leaf development. In summary, our results provide a comprehensive genome-wide study of the YABBY gene family in bamboos, which could be useful for further detailed studies of the function and evolution of the YABBY genes, and to provide a fundamental basis for the study of YABBY in Gramineae for resistance to stress and hormonal stress.

Abstract Background: Members of the AT-HOOK MOTIF CONTAINING NUCLEAR LOCALIZED ( AHL ) family are involved in various plant biological processes via protein-DNA and protein-protein interaction. However, no the systematic identification and analysis of AHL gene family have been reported in cotton. Results: To investigate the potential functions of AHLs in cotton, genome-wide identification, expressions and structure analysis of the AHL gene family were performed in this study. 48, 51 and 99 AHL genes were identified from the G.raimondii, G.arboreum and G.hirsutum genome, respectively. Phylogenetic analysis revealed that the AHLs in cotton evolved into 2 clades, Clade-A with 4-5 introns and Clade-B with intronless (excluding AHL 20-2). Based on the composition of the AT-hook motif(s) and PPC/DUF 296 domain, AHL proteins were classified into three types (Type-I/-II/-III), with Type-I AHLs forming Clade-B, and the other two types together diversifying in Clade-A. The detection of synteny and collinearity showed that the AHLs expanded with the WGD in cotton, and the sequence structure of AHL20-2 showed the tendency of increasing intron in three different Gossypium spp . The ratios of non-synonymous (Ka) and synonymous (Ks) substitution rates of orthologous gene pairs revealed that the AHL genes of G.hirsutum had undergone through various selection pressures, purifying selection mainly in A-subgenome and positive selection mainly in D-subgenome. Examination of their expression patterns showed most of AHLs of Clade-B expressed predominantly in stem, while those of Clade-A in ovules, suggesting that the AHLs within each clade shared similar expression patterns with each other. qRT-PCR analysis further confirmed that some GhAHLs higher expression in stems and ovules. Conclusion: In this study, 48, 51 and 99 AHL genes were identified from three cotton genomes respectively. AHLs in cotton were classified into two clades by phylogenetic relationship and three type based on the composition of motif and domain. The AHLs expanded with segmental duplication, not tandem duplication. The expression profiles of GhAHLs revealed abundant differences in expression levels in various tissues and at different stages of ovules development. Our study provided significant insights into the potential functions of AHLs in regulating the growth and development in cotton.

Abstract Background: Canopy architecture is critical in determining the light environment, and subsequently the photosynthetic productivity of fruit crops. Numerous CCT domain-containing genes are crucial for plant adaptive responses to diverse environmental cues. Due to the biological importance of CCT genes, many researchers have focused on their functional characterization. However, little information was available about the CCT genes (PbCCTs) of pear, an important fruit crop.Results: Genome-wide sequence analysis identified 42 putative PbCCTs in the genome of pear (Pyrus bretschneideri Rehd.). Phylogenetic analysis indicated these genes were divided into five subfamilies, namely, COL (14 members), PRR (8 members), ZIM (6 members), TCR1 (6 members) and ASML2 (8 members). Analysis of exon-intron structures and conserved domains provided support for the classification. Genome duplication analysis indicated that segmental duplication events played a crucial role in the expansion of the CCT family in pear, and that the CCT family evolved under the effect of purifying selection. Expression profiles exhibited diverse expression patterns of PbCCTs in various tissues and in response to varying red and blue light. Additionally, transient overexpression of PbPRR2 in Nicotiana benthamiana leaves resulted in inhibition of photosynthetic performance, suggesting that PbPRR2 may be a negative regulator of photosynthesis. Conclusions:This study provides a comprehensive analysis of the CCT gene family in pear and will facilitate further functional investigations of the PbCCTs to uncover their biological roles in light response.
