“…TCP genes are involved in plant development and cell proliferation (Nicolas & Cubas, ). CmTCP1/TEN belongs, to the subgroup CYC1 of the Class II TCP gene family (Mizuno et al ., ; Dhaka et al ., ). CYC1 genes maintained their TEOSINTE BRANCHED1‐like ( TB1‐like ) role across different taxa, as they negatively regulate axillary bud outgrowth in monocots and eudicots (Dhaka et al ., ).…”

The climbing habit has evolved multiple times during the evolutionary history of angiosperms. Plants evolved various strategies for climbing, such as twining stems, tendrils and hooks. Tendrils are threadlike organs with the ability to twine around other structures through helical growth; they may be derived from a variety of structures, such as branches, leaflets and inflorescences. The genetic capacity to grow as a tendrilled climber existed in some of the earliest land plants; however, the underlying molecular basis of tendril development has been studied in only a few taxa. Here, we summarize what is known about the molecular basis of tendril development in model and candidate model species from key tendrilled families, that is, Fabaceae, Vitaceae, Cucurbitaceae, Passifloraceae and Bignoniaceae. Studies on tendril molecular genetics and development show the molecular basis of tendril formation and ontogenesis is diverse, even when tendrils have the same ontogenetic origin, for example leaflet-derived tendrils in Fabaceae and Bignoniaceae. Interestingly, all tendrils perform helical growth during contact-induced coiling, indicating that such ability is not correlated with their ontogenetic origin or phylogenetic history. Whether the same genetic networks are involved during helical growth in diverse tendrils still remains to be investigated.

“…TCP is named after the first three identified members: TEOSINTE BRANCHED1 (tb1) in maize (Zea mays), CYCLOIDEA (CYC) in snapdragon (Antirrhinum majus), and the PROLIFERATING CELL FACTORS 1 and 2 (PCF1 and PCF2) in rice (Oryza sativa) [1][2][3]. The TCP gene family encodes a 59-amino-acid residue, noncanonical basic helix-loop-helix (bHLH) motif called the TCP domain, which allows DNA binding and protein-protein interactions [3][4][5]. Based on the differences between the TCP domains, the TCP family was divided into two major classes: class I (also known as PCF or TCP-P) and class II (also known as TCP-C) [6][7][8].…”

The TEOSINTE BRANCHED1, CYCLOIDEA, and PROLIFERATION CELL FACTOR (TCP) transcription factor is a plant-specific gene family and acts on multiple functional genes in controlling growth, development, stress response, and the circadian clock. In this study, a class I member of the TCP family from Fraxinus mandshurica Rupr. was isolated and named FmTCP15, which encoded a protein of 362 amino acids. Protein structures were analyzed and five ligand binding sites were predicted. The phylogenetic relationship showed that FmTCP15 was most closely related to Solanaceae and Plantaginaceae. FmTCP15 was localized in the nuclei of F. mandshurica protoplast cells and highly expressed in cotyledons. The expression pattern revealed the FmTCP15 response to multiple abiotic stresses and hormone signals. Downstream genes for transient overexpression of FmTCP15 in seedlings were also investigated. A yeast two-hybrid assay confirmed that FmTCP15 could interact with DELLA proteins. FmTCP15 participated in the GA-signaling pathway, responded to abiotic stresses and hormone signals, and regulated multiple genes in these biological processes. Our study revealed the potential value of FmTCP15 for understanding the molecular mechanisms of stress and hormone signal responses.

“…The Teosinte branched1/Cycloidea/Proliferating cell factor (TCP) family is a group of plant-specific transcription factors (TFs) that involved in embryonic growth, leaf development, branching, flowering, circadian rhythm, hormone signalling, stress responses and so on [1][2][3][4][5][6][7][8][9]. TCP family proteins contain a highly conserved TCP domain that formed with an N-terminal region enriched in basic amino acids followed by two amphipathic α-helices connected by a disordered loop [10,11].…”

Background Teosinte branched1/Cycloidea/Proliferating cell factor (TCP) proteins are plant-specific transcription factors, which widely involved in leaf development, flowering, shoot branching, and circadian rhythm. So far, TCP proteins function in tumorous stem mustard has not been reported. . Here we identified and characterized the entire TCP protein family members in the tumorous stem mustard. Results We identified fifty-four TCP genes in Brassica juncea var. tumida, containing thirty-three Class I subfamily members and twenty-one Class II subfamily members. Fifty-three TCP genes are distributed on 15 chromosomes. Gene structure and conserved motif analysis showed that the same clade genes have similar gene intron/exon structure and conserved motifs. Cis-acting element results showed that the same clade genes also have similar cis-element, however subtle differences also imply the different regulated pathway. More than twice paralogs genes relation to diploid species in some members imply gene duplication events in evolution. The members of BjTCP18s are low expressed in DY strains and un-swelling stage of YA strains. After treatment with GA and SA, it was detected that the expression levels of multiple TCP genes were affected by these two hormones. Conclusion In this study, we perform the first genome-wide analysis of the tumorous stem mustard TCP gene family. The results provide valuable information for understanding the classification and functions of TCP genes in tumorous stem mustard.
