Abstract Background: Apple ( Malus domestica Borkh.) is one of the most popular cultivated fruit crops in China. Apple floral transition is an important process but liable to be affected by various environmental factors. The 14-3-3 proteins are involved in regulating diverse biological processes in plants, and some 14-3-3 members have been identified to play vital roles in flowering. However, little information was available about the 14-3-3 members in apple. Results: In the current study, we identified eighteen 14-3-3 gene family members from apple genome database, designated MdGF14a to MdGF14r , 17 of them are transcribed. The isoforms possess a conserved core region composed of nine antiparallel α-helices and divergent N and C termini. According to their structural and phylogenetic features, Md14-3-3s classified into two major evolutionary branches, the epsilon (ɛ) group and the non-epsilon (non-ɛ) group. Moreover, expression profiles derived from transcriptome data and quantitative reverse-transcription PCR (qRT-PCR) analysis exhibited diverse expression patterns of Md14-3-3 genes in various tissues and in response to different sugars and hormones treatments during floral transition phase. Four Md14-3-3 isoforms ( MdGF14a , MdGF14d , MdGF14i and MdGF14j ) exhibiting prominent transcriptional responses to sugars and hormones were selected for further investigation. Subcellular localization of four selected Md14-3-3 proteins demonstrated their localization in both the cytoplasm and nucleus. Furthermore, yeast two-hybrid and bimolecular fluorescence complementation (BiFC) experiments showed that the four Md14-3-3 proteins interact with key floral integrators, MdTFL1 (TERMINAL FLOWER1) and MdFT (FLOWERING LOCUS T). Conclusion: We comprehensively identified Md14-3-3s family in apple. Some Md14-3-3 genes are predominantly expressed during apple flowering transition stage, and may participate in regulation of flowering through association with flower control genes. Our results provide a preliminary framework for further investigation into the roles of Md14-3-3s for flower transition.

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.

The TIFY gene family is specific to land plants, exerting immense influence on plant growth and development as well as responses to biotic and abiotic stresses. Here, we identify 25 TIFY genes in the poplar (Populus trichocarpa) genome. Phylogenetic tree analysis revealed these PtrTIFY genes were divided into four subfamilies within two groups. Promoter cis-element analysis indicated most PtrTIFY genes possess stress- and phytohormone-related cis-elements. Quantitative real-time reverse transcription polymerase chain reaction (qRT–PCR) analysis showed that PtrTIFY genes displayed different expression patterns in roots under abscisic acid, methyl jasmonate, and salicylic acid treatments, and drought, heat, and cold stresses. The protein interaction network indicated that members of the PtrTIFY family may interact with COI1, MYC2/3, and NINJA. Our results provide important information and new insights into the evolution and functions of TIFY genes in P. trichocarpa.

Protein disulfide isomerases (PDIs) are pivotal protein folding catalysts in the endoplasmic reticulum (ER) through formation of disulfide bond, isomerization, and inhibition of misfolded protein aggregation. When protein folding capacity is overwhelmed by the demands during transitions between growth phases or under environmental changes, the accumulation of unfolded or misfolded proteins in the ER triggers ER stress. However, little is known about PDI gene family in the model legume, Medicago truncatula, especially the responses to ER stress. Therefore, we identified 17 putative PDIs from the genome of M. truncatula and presented their gene and protein structures, phylogenetic relationships, chromosomal distributions, and synteny analysis with the orthologs in other four eudicot species inculding A. thaliana, G. max, B. rapa, and V. vinifera. Moreover, expression profiles derived from transcriptome data showed distinct expression patterns of MtPDI genes among plant organs, while real-time quantitative PCR analysis and data from the proteome revealed the potential roles of MtPDIs in response to ER stress. Our study provides a foundation for further investigations of the biological roles of PDIs in Medicago, especially their roles in response to ER 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: CCCH Zinc finger ( Znf ) transcription factors ( TF ), as a novel type Znf genes, regulate genes expression by binding on their mRNA and play important roles in plant abiotic stress, growth and development. However, no overall genome-wide analysis or expression profiling of CCCH ( C3H ) gene family in Dimocarpous longan , especially during the early stages of somatic embryo in longan has been studied. Longan is a tropical/subtropical fruit tree of great economic importance in Southeast Asia,and longan embryogenesis is the main factor affecting fruit quality and yield. Results: In this study, a comprehensive analysis of longan C3H （ DlC3H ）gene family was carried out. 49 DlC3H genes were identified from longan genome database,which divided into 3 clades. Besides, genes characteristics, phylogenetic tree, gene structure, motif composition were comprehensively analyzed. The analysis of alternative splicing events (AS) suggested that AS events of DlC3H genes were related to longan non-embryonic and embryonic callus transformation. Promoter analysis indicted that most of DlC3H genes included cis -elements associated with hormones and stress response. Quantitative real-time PCR analysis indicated that 26 DlC3Hs ,which possess MeJA and ABA responsive cis -elements, showed different expression patterns and may involved into ABA and MeJA signaling pathway. The expression profiles of 17 DlC3Hs were performed in four stages of longan, the results showed that only DlC3H01/07/14/16/38 was consistent with the data in the transcriptome. DlC3H 07/14/16/36/49 were highly expressed in EC and only DlC3H 04/38 was in GE , suggesting that they have different functions in embryonic development. Finally, sRNAs were verified involved into regulating 6 DlC3Hs . Conclusion: This study provides the first systematic analysis of CCCH protein in longan somatic embryo. Particularly, CCCH genes may be involved in hormone and stress respond, and somatic embryogenesis. Our results presented here may provide a insight into the characteristics and functions of this family in somatic embryogenesis.
