“…Our study identified seven genes in petunia belonging to the members of CYC/TB1 subclade, namely PaTCP1a/b, PaTCP12a/b and PaTCP18a/b/c, which are corresponding to the CYC2, CYC3 and CYC1 group, respectively. The three petunia CYC1 group of genes (PaTCP18a/b/c) are all expressed predominantly in vegetative axillary buds ( Figure 5), which is consistent with the expression patterns of BRANCHED1-like genes in other species, such as AtBRC1 (AtTCP18) and AtBRC2 (AtTCP12) in Arabidopsis [6], PsBRC1 in pea [65], SlBRC1s in tomato [66] and CsBRC1 in cucumber [67], suggesting that PaTCP18a/b/c have a conserved role in regulating axillary bud outgrowth and shoot branching. This was supported by the recent study that identified PhTCP3 (corresponding to PaTCP18c in this study) acting downstream strigolactone (SL) signaling to regulate lateral branching in petunia [51].…”

The plant-specific TCP transcription factors are well-characterized in both monocots and dicots, which have been implicated in multiple aspects of plant biological processes such as leaf morphogenesis and senescence, lateral branching, flower development and hormone crosstalk. However, no systematic analysis of the petunia TCP gene family has been described. In this work, a total of 66 petunia TCP genes (32 PaTCP genes in P. axillaris and 34 PiTCP genes in P. inflata) were identified. Subsequently, a systematic analysis of 32 PaTCP genes was performed. The phylogenetic analysis combined with structural analysis clearly distinguished the 32 PaTCP proteins into two classes—class Ι and class Ⅱ. Class Ⅱ was further divided into two subclades, namely, the CIN-TCP subclade and the CYC/TB1 subclade. Plenty of cis-acting elements responsible for plant growth and development, phytohormone and/or stress responses were identified in the promoter of PaTCPs. Distinct spatial expression patterns were determined among PaTCP genes, suggesting that these genes may have diverse regulatory roles in plant growth development. Furthermore, differential temporal expression patterns were observed between the large- and small-flowered petunia lines for most PaTCP genes, suggesting that these genes are likely to be related to petal development and/or petal size in petunia. The spatiotemporal expression profiles and promoter analysis of PaTCPs indicated that these genes play important roles in petunia diverse developmental processes that may work via multiple hormone pathways. Moreover, three PaTCP-YFP fusion proteins were detected in nuclei through subcellular localization analysis. This is the first comprehensive analysis of the petunia TCP gene family on a genome-wide scale, which provides the basis for further functional characterization of this gene family in petunia.

Background Teosinte branched1/Cycloidea/proliferating cell factors (TCPs) are plant-specific transcription factors widely involved in leaf development, flowering, shoot branching, the circadian rhythm, hormone signaling, and stress responses. However, the TCP function in Brassica juncea var. tumida, the tumorous stem mustard, has not yet been reported. This study identified and characterized the entire TCP family members in B. juncea var. tumida. Methods We identified 62 BjTCP genes from the B. juncea var. tumida genome and analyzed their phylogenetic relationship, gene structure, protein motifs, chromosome location, and expression profile in different tissues. Results Of the 62 BjTCP genes we identified in B. juncea var. tumida, containing 34 class I and 28 class II subfamily members, 61 were distributed on 18 chromosomes. Gene structure and conserved motif analysis showed that the same clade genes displayed a similar exon/intron gene structure and conserved motifs. Cis-acting element results showed that the same clade genes also had a similar cis-acting element; however, subtle differences implied a different regulatory pathway. The BjTCP18s members were low-expressed in Dayejie strains and the unswelling stage of Yonganxiaoye strains. Treatment with gibberellin (GA) and salicylic acid (SA) showed that GA and SA affect the expression levels of multiple TCP genes. Conclusion We performed the first genome-wide analysis of the TCP gene family of B. juncea var. tumida. Our results have provided valuable information for understanding the classification and functions of TCP genes in B. juncea var. tumida.

“…These results suggested that the role of WOX8/9 in regulating shoot architecture is conserved in different species. Recent studies showed that auxin plays important roles in regulating fruit length and shoot branching 32,41 . Future studies will need to unravel whether WOX9 controls branch growth by regulating auxin synthesis or/and transport.…”

WUSCHEL-related homeobox (WOX) transcription factors are plant-specific members that characterized by the presence of a homeodomain. it has been shown that WoX members regulate several aspects of plant development, but the biological functions of this CsWOX gene family remain largely unknown in cucumber (Cucumis sativus L.). In this study, we identified and characterized 11 putative CsWOX genes in cucumber, which are also divided into three major clades (e.g., the Ancient clade, the Intermediate clade and the WUS clade). Expression pattern analysis revealed tissue-specific expression patterns of CsWOX genes, including that CsWOX9 is mainly expressed in developing fruit and also has lower expression in tip and axillary bud, which was further confirmed by in situ hybridization assay. Moreover, overexpression of CsWOX9 in Arabidopsis led to increased branches and rosette leaves, and shorter siliques. together, these results indicated that csWoX members may regulate cucumber growth and development. WUSCHEL-related homeobox (WOX) gene family are plant-specific transcription factors, which belong to homeobox superfamily. All WOX members contain a homeodomain with 60-66 amino acid residues. According to evolutionary relationships, they can be divided into WUS, Intermediate and Ancient clades 1-3. These WOX members have been identified and studied in many species including Arabidopsis, rice, maize and soybean. So far, it has been found that WOX transcription factors play important roles in regulating many aspects of growth and development including meristematic stem cell maintenance, embryonic development and polarization, lateral organ development, and organ regeneration. The founding member AtWUS is expressed in stem apical meristem (SAM) and is necessary for SAM formation and maintenance 2,4-6. In addition to AtWUS, other WOX members are also involved in stem cell maintenance. For example, AtWOX5 is enriched in the quiescent center and plays an important role in maintaining the stability of stem cells of root apical meristem, similar to AtWUS in SAM 7. WOX4 is mainly expressed in the procambium and cambium, and promotes differentiation and/or maintenance of the vascular procambium in Arabidopsis and tomato 8,9. WOX9 promotes the growth of SAM and is required for the maintenance of WUS expression at the shoot apex, and mediates cytokinin signaling during shoot meristem establishment 10. The involvement of WOX members in plant development is not limited to stem cell maintenance. For example, AtWOX2 contributes to early pre-embryo and cotyledon boundary formation during embryo development in the egg cell and zygote 11. Consistently, PaWOX2 also likely regulates embryo cell division and/or differentiation in Picea abies 12. AtWOX7 is expressed at all stages of lateral root development, and inhibits lateral root development in a sugar-dependent manner 13. Similarly, OsWOX6 and OsWOX11 are expressed asymmetrically in response to auxin control rice tiller angle 14. Moreover, AtWOX11 and AtWOX12 play important roles in de nov...
