“…Many studies have shown that TCP family members play essential roles in organ morphogenesis. For example, AtTCP4 is an important regulator of flower organ development in Arabidopsis [14], and AtTCP3/4 can promote shoot organogenesis via regulating the expression of a negative cytokinin response regulator, AtARR16 [15]. AtTCP17, AtTCP5, and AtTCP13 influence the hormone metabolic pathway and thus affect the length of hypocotyl by regulating the expression of the light-sensitive signal factor PIF [50].…”

“…The plant-specific TCP gene family not only plays a role in developmental processes throughout the plant's entire life but also interacts with endogenous (circadian rhythm and plant hormones) and environmental (pathogens, light, temperature, nutrients, salt, and drought stress) signals to ensure plant suitability and health. Many important developmental processes are mediated by TCP family members through different mechanisms, such as embryonic development [11], leaf morphogenesis [12], bud dormancy [13], petal development [14], shoot growth [15], and senescence [16]. In Prunus persica (L.) Batsch, a perennial deciduous tree, PpTCP20, promotes peach flower bud dormancy by negatively regulating the expression of dormancy-associated genes PpDAM5 and PpDAM6 and interacts with PpABF2 to form heterodimers [17].…”

The plant-specific transcription factors TEOSINTE BRANCHED1/CYCLO IDEA/PROLIFERATING CELL FACTOR1 (TCP) act as developmental regulators that have many roles in the growth and development processes throughout the entire life span of plants. TCP transcription factors are responsive to endogenous and environmental signals, such as salt stress. However, studies on the role of the TCP genes in salt stress response have rarely focused on woody plants, especially forest trees. In this study, the BpTCP3 gene, a CYC/TB1 subfamily member, isolated from Betula platyphylla Sukaczev, was significantly influenced by salt stress. The β-glucuronidase (GUS) staining analysis of transgenic B. platyphylla harboring the BpTCP3 promoter fused to the reporter gene GUS (pBpTCP3::GUS) further confirmed that the BpTCP3 gene acts a positive regulatory position in salt stress. Under salt stress, we found that the BpTCP3 overexpressed lines had increased relative/absolute high growth but decreased salt damage index, hydrogen peroxide (H2O2), and malondialdehyde (MDA) levels versus wild-type (WT) plants. Conversely, the BpTCP3 suppressed lines exhibited sensitivity to salt stress. These results indicate that the BpTCP3 transcription factor improves the salt tolerance of B. platyphylla by reducing reactive oxygen species damage, which provides useful clues for the functions of the CYC/TB1 subfamily gene in the salt stress response of B. platyphylla.

Plant-specific TCP transcription factors play an essential role in plant growth and development. They can regulate leaf curvature, flower symmetry and the synthesis of secondary metabolites. The flavonoids in Ginkgo biloba leaf are one of the main medicinally bioactivate compounds, which have pharmacological and beneficial health effects for humans. In this study, a total of 13 TCP genes were identified in G. biloba , and 5 of them belonged to PCF subclades ( GbTCP03, GbTCP07, GbTCP05, GbTCP13, GbTCP02 ) while others belonged to CIN ( GbTCP01, GbTCP04, GbTCP06, GbTCP08, GbTCP09, GbTCP10, GbTCP11, GbTCP12 ) subclades according to phylogenetic analysis. Numerous cis -acting elements related to various biotic and abiotic signals were predicted on the promoters by cis -element analysis, suggesting that the expression of GbTCPs might be co-regulated by multiple signals. Transcript abundance analysis exhibited that most of GbTCPs responded to multiple phytohormones. Among them, the relative expression levels of GbTCP06, GbTCP11 , and GbTCP13 were found to be significantly influenced by exogenous ABA, SA and MeJA application. In addition, a total of 126 miRNAs were predicted to target 9 TCPs (including GbTCP01, GbTCP02, GbTCP04, GbTCP05, GbTCP06, GbTCP08, GbTCP11, GbTCP12, GbTCP13 ). The correlation analysis between the expression level of GbTCPs and the flavonoid contents showed that GbTCP03, GbTCP04, GbTCP07 might involve in flavonoid biosynthesis in G. biloba . In short, this study mainly provided a theoretical foundation for better understanding the potential function of TCPs in G. biloba .

“…Some studies showed that TCP transcription factors might be regulated by sucrose, cytokinin and strigolactone in several species (Manassero et al 2013 ; Moreno-Pachon et al 2017 ). A recent study suggested that TCP and its target miR319 were regulated by HUA ENHANCER 1 (HEN1) and played a crucial role in the shoot organogenesis of mutants and overexpression plants (Yang et al 2020 ). However, the effects of TCP on bulblet generation in Lilium remain unclear.…”

Main conclusion HRW increased the content of starch and sucrose via regulating a series of sucrose and starch synthesis genes, which induced the formation of bulblets and adventitious roots of Lilium davidii var. unicolor. Abstract Hydrogen gas (H 2 ), as a signaling molecule, has been reported to be involved in plant growth and development. Here, the effect of hydrogen-rich water (HRW) on the formation of bulblets and adventitious roots in the scale cuttings of Lilium davidii var. unicolor and its mechanisms at the molecular levels were investigated. The results revealed that compared with distilled water treatment (Con), the number of bulblets and adventitious roots were significantly promoted by different concentrations of HRW treatment. Treatment with 100% HRW obtained the most positive effects. RNA sequencing (RNA-seq) analysis found that compared with Con, a total of 1702 differentially expressed genes (DEGs, upregulated 552 DEGs, downregulated 1150 DEGs) were obtained under HRW treatment. The sucrose and starch metabolism, cysteine and methionine metabolism and phenylalanine metabolism were significantly enriched in the analysis of the Kyoto encyclopedia of genes and genomes (KEGG). In addition, the genes involved in carbohydrate metabolism were significantly upregulated or downregulated (upregulated 22 DEGs, downregulated 15 DEGs), indicating that starch and sucrose metabolism held a central position. The expressions of 12 DEGs were identified as coding for key enzymes in metabolism of carbohydrates was validated by qPCR during bulblet formation progress. RNA-seq analysis and expression profiles indicated that the unigene levels such as glgc, Susy, otsA and glgP, BMY and TPS were well correlated with sucrose and starch metabolism during HRW-induced bulblet formation. The change of key enzyme content in starch and sucrose metabolism pathway was explored during bulblet formation in Lilium under HRW treatment. Meanwhile, compared with Con, 100% HRW treatment increased the levels of sucrose and starch, and decreased the trehalose content, which were agreed with the expression pattern of DEGs related to the biosynthesis pathway of sucrose, starch and trehalose. Therefore, this study suggested that HRW could promote the accumulation of sucrose and starch contents in mother scales, and decreased the trehalose content, this might provide more energy for bulblet formation.
