“…The PCF gene, a member of the TCP gene family in Oryza sativa, activates the expression of the NHX gene, thereby improving the plant's salt tolerance [51]. The salt tolerance of the TCP-overexpressing plants was stronger than that of the wild-type plants under salt stress [65]. NHX genes play an important role in plants' response to salt stress [66].…”

Amaranth species are C4 plants that are rich in betalains, and they are tolerant to salinity stress. A small family of plant-specific TCP transcription factors are involved in the response to salt stress. However, it has not been investigated whether amaranth TCP1 is involved in salt stress. We elucidated that the growth and physiology of amaranth were affected by salt concentrations of 50–200 mmol·L−1 NaCl. The data showed that shoot and root growth was inhibited at 200 mmol·L−1, while it was promoted at 50 mmol·L−1. Meanwhile, the plants also showed physiological responses, which indicated salt-induced injuries and adaptation to the salt stress. Moreover, AtrTCP1 promoted Arabidopsis seed germination. The germination rate of wild-type (WT) and 35S::AtrTCP1-GUS Arabidopsis seeds reached around 92% by the seventh day and 94.5% by the second day under normal conditions, respectively. With 150 mmol·L−1 NaCl treatment, the germination rate of the WT and 35S::AtrTCP1-GUS plant seeds was 27.0% by the seventh day and 93.0% by the fourth day, respectively. Under salt stress, the transformed 35S::AtrTCP1 plants bloomed when they grew 21.8 leaves after 16.2 days of treatment, which was earlier than the WT plants. The transformed Arabidopsis plants flowered early to resist salt stress. These results reveal amaranth’s growth and physiological responses to salt stress, and provide valuable information on the AtrTCP1 gene.

“…The TCP transcription factor family has been identified in a diverse array of plants, but unlike other transcription factor families, such as MYB (V-myb avian myeloblastosis viral), WRKY (WRKY proteins contain one or two conserved WRKYGQK motifs at the N-terminus and a typical zinc-finger motif (C2H2 and C2HC) at the C-terminus), and NAC (The name of the NAC gene family is composed of the initials NAM (No apical meristem from Petunia hybrida ), AF1/2 (transcriptional activator 1/2 from Arabidopsis thaliana ), and CUC2 (cup-shaped cotyledon from Arabidopsis thaliana ) transcription factors. ), the TCP family usually comprises fewer members, with 24 in Arabidopsis thaliana [ 11 ], 32 in morning glory ( Catharanthus roseus ) [ 12 ], 27 in watermelon ( Citrullus lanatus ) [ 13 ], 26 in Chinese cabbage ( Brassica rapa ) [ 14 ], 30 in tomato ( Solanum lycopersicum ) [ 15 ], 20 in citrus ( Citrus ) [ 16 ], 26 in bitter buckwheat ( Fagopyrum esculentum ) [ 17 ], 40 in moso bamboo ( Phyllostachys pubescens ) [ 18 ], 18 in grape ( Vitis vinifera ) [ 19 ], and 62 in blueberry ( Vaccinium corymbosum ) [ 20 ]. The functions of the TCP family have been revealed over time, from initially preventing axillary bud tip growth [ 5 ] and controlling floral symmetry [ 6 ] to addressing abiotic stresses [ 14 , 16 , 17 ], biotic stresses [ 21 ], plant height [ 13 ], fruit maturation [ 15 ], anthocyanin accumulation [ 9 , 22 ], hormonal pathways [ 19 ], and bud dormancy [ 20 ].…”

Background TCP proteins are plant specific transcription factors that play important roles in plant growth and development. Despite the known significance of these transcription factors in general plant development, their specific role in fruit growth remains largely uncharted. Therefore, this study explores the potential role of TCP transcription factors in the growth and development of sweet cherry fruits. Results Thirteen members of the PavTCP family were identified within the sweet cherry plant, with two, PavTCP1 and PavTCP4, found to contain potential target sites for Pav-miR159, Pav-miR139a, and Pav-miR139b-3p. Analyses of cis-acting elements and Arabidopsis homology prediction analyses that the PavTCP family comprises many light-responsive elements. Homologs of PavTCP1 and PavTCP3 in Arabidopsis TCP proteins were found to be crucial to light responses. Shading experiments showed distinct correlation patterns between PavTCP1, 2, and 3 and total anthocyanins, soluble sugars, and soluble solids in sweet cherry fruits. These observations suggest that these genes may contribute significantly to sweet cherry light responses. In particular, PavTCP1 could play a key role, potentially mediated through Pav-miR159, Pav-miR139a, and Pav-miR139b-3p. Conclusion This study is the first to unveil the potential function of TCP transcription factors in the light responses of sweet cherry fruits, paving the way for future investigations into the role of this transcription factor family in plant fruit development.
