P. bretschneideri is a commercial fruit available worldwide. Pyrus bretschneideri Rehder, Proc. The chromosome numbers of F. vesca, P. mume and P. persica were 14, 16 and 16, respectively, while the chromosome number of both P. communis and P. bretschneideri was 34 (Shulaev et al., 2011; Zhang et al., 2012; Verde et al., 2013; Wu et al., 2013; Chagné et al., 2014), implying that the members of BZR gene family might have undergone an expansion corresponding to chromosome number variation. (2010). P < 0.05 was considered as the threshold for significance (**P < 0.01 and *P < 0.05). A 512.0-Mb sequence corresponding to 97.1% of the estimated genome size of this highly heterozygous species is assembled Figure 5 Subcellular localization (A) and transcriptional activity (B) assay. Nucleic Acids Res. The spectrum from blue to red indicates the relative expression level from 0 to 6. Genomic fragments are suggested by numbers of triangles. By loading these files, the microsynteny diagrams were achieved. 7, 562. doi: 10.1038/nprot.2012.016, Verde, I., Abbott, A. G., Scalabrin, S., Jung, S., Shu, S., Marroni, F., et al. There are also two nice trees at the Hillier Gardens. There are currently no active references in this article. Values are presented as mean ± SE of three biological replicates. A Brassinosteroid-Insensitive Mutant in Arabidopsis thaliana Exhibits Multiple Defects in Growth and Development. A! In addition, some BZR proteins contained PEST domain and serine (S)-rich phosphorylation sites, which were represented by the motif 5 and motif 6, respectively, in the middle portions of these sequences (Figure S4). Brassinosteroids can regulate cellulose biosynthesis by controlling the expression of CESA genes in Arabidopsis. Pyrus can make substantial, long-lived trees. YuC, LJ, LW, DM, and XL analyzed the data. Front. PloS One 9, e92644. doi: 10.1016/j.scienta.2013.03.020, Kim, D., Pertea, G., Trapnell, C., Pimentel, H., Kelley, R., Salzberg, S. L. (2013). Interspecific hybrid species of pear native to North China, where it is widely grown for its edible fruit. (A) Diagram of the VIGS technique used for infecting the P. bretschneideri fruits. 24, 1586–1591. BZR transcription factors are associated with plant cell growth and photomorphogenesis by interacting with the Phytochrome-interacting factor (PIF) family genes and DELLA genes (Gallegobartolome et al., 2012; Li et al., 2012; Oh et al., 2012). Among P. bretschneideri and other four Rosaceae species (i.e. However, there is limited information about the MADS family and its functional divergence in pear. The sliding window analysis further confirmed that many sites/regions are under neutral to strong purifying selection, as predicted by the Ka/Ks analysis described above (Figure 4). Analysis of relative gene expression data using real-time quantitative PCR and the 2– ΔΔCT method. Amer. Terminal (leaf) node. Pyrus × bretschneideri in the Germplasm Resources Information Network (GRIN), U.S. Department of The Pfam protein families database. The previously published studies have proven that the BZR protein has a highly conserved N-terminal domain with DNA-binding activity in vitro and in vivo (He et al., 2005; Yin et al., 2005). Previous studies have shown that stone cell content is a key factor affecting P. bretschneideri fruit flavor (Jin et al., 2013; Cao et al., 2016c). The members of this superfamily are vital for cell wall construction during plant growth and development. (2011). were selected as materials from a commercial orchard in Dali County, Shaanxi Province, China, in 2014 and 2015. Comparative genomic analysis of the GRF genes in Chinese pear (Pyrus bretschneideri Rehd), poplar (Populous), grape (Vitis vinifera), Arabidopsis and rice (Oryza sativa). These data suggested that PbBZR1, PbBZR2 and PbBZR3 were nuclear proteins, which were similar to ZmBZRs(Yu et al., 2018). Pests of Pyrus bretschneideri (PYUBR) Organism Type; Anastrepha fraterculus (as Pyrus) (ANSTFR) Incidental: Carposina sasakii (as Pyrus) (CARSSA) These results implied that both exon loss and gain has occurred during the long evolutionary period of the BZR gene family, which further may explain the functional differences of closely related-BZR gene family members. Nucleic Acids Res. Collectively, our research reveals that a regulatory network mediated by PbBZRs assists a solid foundation for future functional studies and molecular breeding to improve P. bretschneideri fruit quality. doi: 10.1093/molbev/msu300, Oh, E., Zhu, J., Wang, Z. (2014). Then these target genes were cloned into the pTRV2 vector, respectively. 40, D302–D305. In our study, a systematic study was performed to identify and characterize the BZR genes in five Rosaceae species. At the end of purification by ion exchange chromatography on DEAE‐cellulose, 10.8‐fold purification was achieved. Integrative Analysis of the Core Fruit Lignification Toolbox in Pear Reveals Targets for Fruit Quality Bioengineering. TBtools, a Toolkit for Biologists integrating various HTS-data handling tools with a user-friendly interface. These data suggest that PbBZR1 is transcriptional repressor of PbHCT6, PbCES9, PbCCoAMOT1, PbCOMT3, and PbCCR20 involved in the direct and indirect regulation of lignin biosynthesis during P. bretschneideri fruit development. In our study, six, eight, eight, twelve and thirteen BZR-coding protein sequences were identified in F.vesca, P. mume, P. persica, P. communis and P. bretschneideri, respectively (Table S1). Left panel: an unrooted phylogenetic tree constructed using MEGA by the N-J method. Pyrus_bretschneideri Detail . Plant Sci., 15 July 2020 These results indicated that PbBZR1 might negatively regulate lignin biosynthesis by suppressing these lignin synthetic genes in P. bretschneideri fruits, which was in line with the previously published manuscripts (Cao et al., 2019). To anchor the scaffolds of P. bretschneideri … doi: 10.1038/ng.740, Tamura, K., Peterson, D., Peterson, N., Stecher, G., Nei, M., Kumar, S. (2011). For example, Pm018690 has one intron, while is orthologous gene ppa025998m contains three introns, and Pbr000539.1 has one intron, while is orthologous gene PCP025025.1 contains two introns. doi: 10.1007/s10725-018-0424-2, Zhang, Q., Chen, W., Sun, L., Zhao, F., Huang, B., Yang, W., et al. 32, 268–274. In P. persica, three BZR gene members were found on chromosome 4, and one member placed on chromosome 2, 3, 4, 5, and 7, respectively (Figure S1). Arts. doi: 10.1093/molbev/msm088, Ye, Q., Zhu, W., Li, L., Zhang, S., Yin, Y., Ma, H., et al. 12, 79. doi: 10.1186/1471-2105-12-79, Cao, Y., Han, Y., Li, D., Lin, Y., Cai, Y. The ** represent significant differences at 0.01 level. Branchlets purplish brown when old, terete, robust, densely pubescent when young, glabrous when old, sparsely lenticellate; buds dark purple, ovoid, apex obtuse; scales pubescent at margin and apex. 45, 487–494. In the present study, any Ks values > 2.0 were discarded because of the risk of saturation (Maher et al., 2006). 2003. To isolate and identify the active ingredients, the ethanol extract was separated into petroleum ether, ethyl acetate, n-butanol, and aqueous fractions.

Impact Factor 4.402 | CiteScore 7.8More on impact ›, Functional Genomics in Fruit Trees: from ‘Omics to Sustainable Biotechnologies It is reported that BZR proteins were located in nucleus, such as ten maize BZR proteins (ZmBZR1, -2, -3, -4, -5, -7, -8, -9, 10 and -11) were targeted to the nucleus (Yu et al., 2018). Bot. Natl. SMART 7: recent updates to the protein domain annotation resource. A! Y-axis indicates the relative abundance of PbBZRs in leaves of TRV control (black) and TRV-PbBZRs-infected (grey) fruits of 55-day-old after infiltration. The conserved motif and multiple sequence alignments analyses showed that most of the BZR proteins contain a typical bHLH domain (basic helix–loop–helix) in these sequences N-termini represented by motif 1 (Figure S4). Figure S5 | Figure S5 The expression of PbBZRs in different tissues (a) and fruit development stages (b). Figure S7 | Figure S7 qRT-PCR assay of key genes in P. bretschneideri lignin metabolic pathway. cv. Figure 8 PbBZR1 inhibits the transcription of PbHCT6, PbCES9, PbCCoAOMT1 and PbCCR20. Distinct transcriptome profiles reveal gene expression patterns during fruit development and maturation in five main cultivated species of pear (Pyrus L.). The ACTIN gene was adopted as the internal control for normalization (Cao et al., 2018). (2009), all the constructs were transformed into tobacco by Agrobacterium infiltration. It is well known that one or more whole-genome duplication events produced significant fluctuations in the size and arrangement of genomes within the five Rosaceae species (Wu et al., 2013).
