As is well known, TCP proteins are plant-specific transcription factors that play an important role in plant and fruit growth and development. Despite the known significance of these transcription factors in general plant development, their specific role in cherry fruit growth remains largely unknown.
The study conducted by the research group of the College of Horticulture at Sichuan Agricultural University in China explored the potential role of TCP transcription factors in cherry fruit growth and development.
Thirteen members of the PavTCP family were identified within the sweet cherry plant, with two, PavTCP1 and PavTCP4 , containing potential target sites for Pav-miR159, Pav-miR139a and Pav-miR139b-3p. Analysis of cis-acting elements and prediction of Arabidopsis homology show that the PavTCP family comprises many light-sensitive elements.
It was found that PavTCP1 and PavTCP3 homologues in Arabidopsis TCP proteins are crucial for light responses. Shading experiments showed distinct correlation patterns between PavTCP1 , 2 and 3 and total anthocyanins, soluble sugars and soluble solids in cherry fruits.
These observations suggest that these genes may contribute significantly to the light responses of sweet cherries. In particular, PavTCP1 could play a key role, potentially mediated by Pav-miR159, Pav-miR139a and Pav-miR139b-3p.
This study is the first to reveal the potential function of TCP transcription factors in the light responses of cherry fruits, paving the way for future investigations into the role of this family of transcription factors in plant fruit development.

Spanish offerings dominated the scene and played a particularly important role in Berlin. Fruit larger than 32 mm cost about EUR 8 per kg. In Hamburg and Cologne, the presence had expanded considerably and were therefore cheaper.

In Chile, the post-transplant survival, canopy growth and productivity of two cultivars were evaluated: Lapins on Colt and Regina on Gisela 12. The cultivars were grown with root volumes of 100%, 50% and 25% and with bare-root or bagged nursery plants.

On December 5, the first Cherry Express shipment of the 2025/26 season arrived at Nansha Port: 8,000 tonnes of fresh Chilean cherries were distributed within two hours thanks to an optimized cold logistics chain. China officially enters peak cherry season.
