Special Issue Information

Dear Colleagues,

This Special Issue on "Reproductive and Developmental Mechanisms of Vegetable Crops" aims to comprehensively explore the fundamental processes underlying the reproduction and growth of vegetable crops. It focuses on elucidating the genetic, molecular, and physiological mechanisms that govern flower formation, pollination, fertilization, and subsequent embryo and seed development. Additionally, it will investigate how environmental cues and hormonal regulations impact the overall developmental trajectory from seedling establishment to the maturation and biotic and abiotic stress response of vegetable plants. The research presented in this Special Issue is expected to provide valuable insights for improving crop breeding strategies, enhancing productivity, and ensuring the sustainable cultivation of vegetable crops by a deeper understanding of their reproductive and developmental intricacies.

Plant height represents a pivotal agronomic trait for the genetic enhancement of crops. The plant cell wall, being a dynamic entity, is crucial in determining plant stature; however, the regulatory mechanisms underlying cell wall remodeling remain inadequately elucidated. This study demonstrates that the application of gibberellin 3 (GA3) enhances both plant height and cell wall remodeling in tomato (Solanum lycopersicum L.) plants. RNA sequencing (RNA-seq) results of GA3 treatment showed that the DEGs were mostly enriched for cell wall-related pathways; specifically, GA3 treatment elicited the expression of the cell wall-associated gene XYLOGLUCAN ENDOTRANSGLUCOSYLASE/HYDROLASE 19 (SlXTH19), whose overexpression resulted in increased plant height. Comparative analyses revealed that SlXTH19-overexpressing lines exhibited larger cell dimensions and increased XTH activity, along with higher contents of lignin, cellulose, and hemicellulose, thereby underscoring the gene’s role in maintaining cell wall integrity. Conversely, treatments with ethephon (ETH) and 1-Naphthaleneacetic acid (NAA) led to suppressed plant height and reduced SlXTH19 expression. Collectively, these findings illuminate a competitive interplay between GA and ethylene/auxin signaling pathways in regulating cell wall remodeling via SlXTH19 activation, ultimately influencing tomato plant height.
