Abstract

(Franch.) Schneid. is an economic fruit plant with high medicinal and edible values. The TCP gene family plays a vital role in plant growth and development. To explore the function of the TCP gene family in the growth and development of . . In this study, the TCP gene family (DdeTCP) members were identified from the . genome and their expression levels at different stages of seed germination and fruit development were analyzed. The results showed that a total of 18 DdeTCP genes were identified from the . genome, with uneven location on 11 chromosomes. The phylogenetic tree showed that the 18 DdeTCPs could be classified into class Ⅱ (3) and class Ⅱ (15), suggesting that functional differentiation occurred among the DdeTCP family members. highly homologous to was highly expressed in the early stage of seed germination, which suggested that this gene played a key role in seed germination. In addition, in class Ⅱ had a high expression level during the fruit ripening stage, which indicated that it might be related to fruit ripening. The findings lay a foundation for probing into the roles of the DdeTCP gene family in the growth and development of . .

摘要

（法）施奈德。是一种具有高药用和食用价值的经济水果植物。TCP基因家族在植物生长发育中起着至关重要的作用。为了探究TCP基因家族在……生长发育中的功能。在本研究中，从……基因组中鉴定出TCP基因家族（DdeTCP）成员，并分析了它们在种子萌发和果实发育不同阶段的表达水平。结果表明，从……基因组中总共鉴定出18个DdeTCP基因，它们在11条染色体上的分布不均匀。系统发育树表明，18个DdeTCP可分为Ⅱ类（3个）和Ⅱ类（15个），这表明DdeTCP家族成员之间发生了功能分化。与……高度同源的……在种子萌发早期高表达，这表明该基因在种子萌发中起关键作用。此外，Ⅱ类中的……在果实成熟阶段表达水平较高，这表明它可能与果实成熟有关。这些发现为探究DdeTCP基因家族在……生长发育中的作用奠定了基础。
