| Zusammenfassung: | Copyright © 2024 Elsevier Masson SAS. All rights reserved. Environmental stress significantly affects plant growth and productivity. The effects of drought stress on plants are reflected primarily in enzyme activity, membrane systems, and cell-water loss. Here, the Kelch repeat F-box (KFB) protein family in tomato was systematically identified and analysed. Using bioinformatics, we identified 37 SlKFB family members in the tomato genome and analysed their protein structure, phylogenetic relationships, chromosome distribution, and expression under drought or biotic-stress conditions. Transcriptome data revealed that SlKFB members exhibit differential responses to drought stress, with significant differences in SlKFB16 and SlKFB34 expression. Functional analysis revealed that SlKFB16 functions in the cytoplasm and SlKFB34 in the nucleus and cytoplasm. Under drought stress, SlKFB16 and SlKFB34-silencing significantly reduced reactive oxygen species scavenging and resistance to drought stress. These findings provide a reference for further studies of the mechanisms of SlKFB16 and SlKFB34 in drought stress in tomato as well as a foundation for enhancing their resistance to drought stress |
