“…While no obvious devel-opmental defects were observed in the stamen and lemma of the rep1 mutants, this may be a reflection of functional redundancy of other genes with REP1 due to gene duplication events of TCP domain family members, or alternatively may mean that REP1 has no critical role in stamen and lemma development. Our phylogenetic analysis revealed 22 putative TCP domaincontaining members in the rice genome (Yao et al, 2007), supporting the hypothesis that lineage-specific expansions of the TCP family members happened during rice genome evolution (Navaud et al, 2007). Therefore, investigations on the REP1-like proteins in the relative grass family will help us to elucidate whether the conserved pathway exists in controlling other grass floral zygomorphy.…”

“…Similarly, forward primer 3#-RACE-S2 was designed based on the sequence between 165 and 183 nucleotides upstream of the putative stop codon to determine the 3#-UTR. The ClustalX tool was used to do multiple sequence alignments and a phylogenetic tree was constructed with the aligned TCP protein sequences using the MEGA (version 3.0) software as we described before (Yao et al, 2007).…”

Poaceae, one of the largest flowering plant families in angiosperms, evolved distinct inflorescence and flower morphology diverging from eudicots and other monocots. However, the mechanism underlying the specification of flower morphology in grasses remains unclear. Here we show that floral zygomorphy along the lemma-palea axis in rice (Oryza sativa) is partially or indirectly determined by the CYCLOIDEA (CYC)-like homolog RETARDED PALEA1 (REP1), which regulates palea identity and development. The REP1 gene is only expressed in palea primordium during early flower development, but during later floral stages is radially dispersed in stamens and the vascular bundles of the lemma and palea. The development of palea is significantly retarded in the rep1 mutant and its palea has five vascular bundles, which is similar to the vascular pattern of the wild-type lemma. Furthermore, ectopic expression of REP1 caused the asymmetrical overdifferentiation of the palea cells, altering their floral asymmetry. This work therefore extends the function of the TCP gene family members in defining the diversification of floral morphology in grasses and suggests that a common conserved mechanism controlling floral zygomorphy by CYC-like genes exists in both eudicots and the grasses.

“…The two amphipathic helical regions are abundant in hydrophobic amino acid residues (Ala, Leu, and Trp), whereas the Loop region contains the hydrophilic amino acids residues (Gly), and all the conserved amino acid residues possibly contribute to the function of DNA binding, protein-protein interactions, and protein nuclear localization (Kosugi and Ohashi, 2002;Yao et al, 2007;Viola et al, 2011). Bioinformatics analysis indicated that the bHLH domain exists in all TCP proteins; only a few of the TCP proteins contain the R domain, which include polar residues and is assumed to develop a hydrophilic α-helix involved in protein-protein interactions (Yao et al, 2007). Based on the variation in the TCP domain, 61 NtTCP proteins can be classified into two groups, known as class I and class II.…”

ABSTRACT. The TCP family is a transcription factor family, members of which are extensively involved in plant growth and development as well as in signal transduction in the response against many physiological and biochemical stimuli. In the present study, 61 TCP genes were identified in tobacco (Nicotiana tabacum) genome. Bioinformatic methods were employed for predicting and analyzing the gene structure, gene expression, phylogenetic analysis, and conserved domains of TCP proteins in tobacco. The 61 NtTCP genes were divided into three diverse groups, based on the division of TCP genes in tomato and Arabidopsis, and the results of the conserved domain and sequence analyses further confirmed the classification of the NtTCP genes. The expression pattern of NtTCP also demonstrated that majority of these genes play important roles in all the tissues, while some special genes exercise their functions only in specific tissues. In brief, the comprehensive and thorough study of the TCP family in other plants provides sufficient resources for studying the structure and functions of TCPs in tobacco.

“…TEOSINTE-BRANCHED1/CYCLOIDEA/PCF (TCPs) constitute a large group of plant-specific genes found in various species, ranging from lower to higher plants, with 24 TCPs in Arabidopsis (Arabidopsis thaliana) and more than 20 TCPs in rice (Oryza sativa; Cubas, 2002;Navaud et al, 2007;Yao et al, 2007). TCP proteins have a TCP domain that contains a helix-loop-helix (bHLH) motif (Martín-Trillo and Cubas, 2010).…”

Plant-specific TEOSINTE-BRANCHED1/CYCLOIDEA/PCF (TCP) transcription factors play crucial roles in development, but their functional mechanisms remain largely unknown. Here, we characterized the cellular functions of the class I TCP transcription factor GhTCP14 from upland cotton (Gossypium hirsutum). GhTCP14 is expressed predominantly in fiber cells, especially at the initiation and elongation stages of development, and its expression increased in response to exogenous auxin. Induced heterologous overexpression of GhTCP14 in Arabidopsis (Arabidopsis thaliana) enhanced initiation and elongation of trichomes and root hairs. In addition, root gravitropism was severely affected, similar to mutant of the auxin efflux carrier PIN-FORMED2 (PIN2) gene. Examination of auxin distribution in GhTCP14-expressing Arabidopsis by observation of auxin-responsive reporters revealed substantial alterations in auxin distribution in sepal trichomes and root cortical regions. Consistent with these changes, expression of the auxin uptake carrier AUXIN1 (AUX1) was up-regulated and PIN2 expression was down-regulated in the GhTCP14-expressing plants. The association of GhTCP14 with auxin responses was also evidenced by the enhanced expression of auxin response gene IAA3, a gene in the AUXIN/INDOLE-3-ACETIC ACID (Aux/IAA) family. Electrophoretic mobility shift assays showed that GhTCP14 bound the promoters of PIN2, IAA3, and AUX1, and transactivation assays indicated that GhTCP14 had transcription activation activity. Taken together, these results demonstrate that GhTCP14 is a dual-function transcription factor able to positively or negatively regulate expression of auxin response and transporter genes, thus potentially acting as a crucial regulator in auxin-mediated differentiation and elongation of cotton fiber cells.
