Abstract

Fruit development is a key biological process that influences yield, fruit quality, and reproductive success. However, the molecular and cellular mechanisms involved in this process remain poorly understood in eggplant (Solanum melongena L.) compared with other Solanaceae species, particularly tomato. The interactions between cellular changes, hormone signalling, and genetic regulation during eggplant fruit development have also received limited attention. This review summarizes research to date on the main stages of eggplant fruit development, namely fruit set, cell division, cell expansion, and maturation. At each stage, we discuss cellular changes, changes in endogenous hormone levels, transcriptional regulation, and the roles of genes associated with fruit shape. The review also examines the effects of phytohormones on cellular processes at different stages and the involvement of transcription factor families, such as MADS-box, TCP, MYB, and bHLH, in hormone responses and gene expression. Fruit-shape genes identified through quantitative trait locus (QTL) mapping and genome-wide association studies are also discussed in relation to the cellular and hormonal processes that affect fruit shape. By considering cellular, hormonal, transcriptional, and genetic regulation together across fruit development, this review brings these aspects together to improve our understanding of eggplant-specific developmental processes and may help guide future breeding efforts aimed at improving yield, fruit uniformity, and quality.

龙葵果实发育的综合调控：从细胞动力学到基因组控制

果实发育是影响果实产量、品质和繁殖成功的关键生物学过程。然而，与其他茄科植物，特别是番茄相比，茄子（Solanum melongena L.）参与这一过程的分子和细胞机制尚不清楚。在茄子果实发育过程中，细胞变化、激素信号和遗传调控之间的相互作用也受到了有限的关注。本文综述了迄今为止关于茄子果实发育的主要阶段，即坐果、细胞分裂、细胞扩增和成熟的研究。在每个阶段，我们讨论了细胞的变化、内源激素水平的变化、转录调控以及与果实形状相关的基因的作用。本综述还探讨了植物激素在不同阶段对细胞过程的影响，以及转录因子家族（如MADS-box、TCP、MYB和bHLH）在激素反应和基因表达中的作用。通过数量性状位点（QTL）定位和全基因组关联研究鉴定的果实形状基因也讨论了影响果实形状的细胞和激素过程的关系。通过考虑细胞、激素、转录和遗传调控在果实发育过程中的共同作用，本综述将这些方面结合在一起，以提高我们对茄子特定发育过程的理解，并可能有助于指导未来旨在提高产量、果实均匀性和质量的育种工作。

期刊介绍： Scientia Horticulturae is an international journal publishing research related to horticultural crops. Articles in the journal deal with open or protected production of vegetables, fruits, edible fungi and ornamentals under temperate, subtropical and tropical conditions. Papers in related areas (biochemistry, micropropagation, soil science, plant breeding, plant physiology, phytopathology, etc.) are considered, if they contain information of direct significance to horticulture. Papers on the technical aspects of horticulture (engineering, crop processing, storage, transport etc.) are accepted for publication only if they relate directly to the living product. In the case of plantation crops, those yielding a product that may be used fresh (e.g. tropical vegetables, citrus, bananas, and other fruits) will be considered, while those papers describing the processing of the product (e.g. rubber, tobacco, and quinine) will not. The scope of the journal includes all horticultural crops but does not include speciality crops such as, medicinal crops or forestry crops, such as bamboo. Basic molecular studies without any direct application in horticulture will not be considered for this journal.
