Future‐proofing ornamental plants: Cutting‐edge strategies for drought resistance and sustainability

Physiologia Plantarum, Journal Year: 2025, Volume and Issue: 177(3)

Published: May 1, 2025

Abstract Drought stress presents a significant challenge to ornamental horticulture, affecting plant growth, aesthetic qualities, and overall resilience. As the demand for aesthetically pleasing sustainable landscapes continues rise, development of drought‐resistant plants becomes increasingly critical. While traditional breeding methods are effective, they time‐consuming labor‐intensive, necessitating integration advanced technologies accelerate creation resilient cultivars. Despite progress in understanding responses drought stress, gap remains effectively translating this knowledge into practical strategies species. This review synthesizes recent advances multifaceted impact on plants, focusing its effects morphology, physiology, biochemical processes, value. We explore key physiological adaptations, including alterations metabolism, pathways, as well molecular involving phytohormones, transcription factors, epigenetic regulation. Additionally, we discuss cutting‐edge such CRISPR/Cas9, synthetic biology, digital phenotyping, which offer promising developing drought‐tolerant Epigenetic modifications, DNA methylation histone alterations, provide with ability “remember” past events, enhancing future The multi‐omics approaches, techniques, tools accelerates identification drought‐responsive genes traits. Finally, highlight directions potential engineering, high‐throughput phenotyping create more plants. These innovative approaches can contribute horticultural practices enhance ecological value changing climate.

Genome-Wide Identification and Expression Analysis of Carotenoid Cleavage Dioxygenase Genes in Salvia miltiorrhiza

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(23), P. 13138 - 13138

Published: Dec. 6, 2024

In the process of catalyzing carotenoids into various apocarotenoids and other derivatives, carotenoid cleavage dioxygenases (CCDs) play key roles. However, little information on CCDs has been reported in regard to Salvia miltiorrhiza. this study, a total 21 CCD genes were identified whole genome S. miltiorrhiza, mainly distributed between five chromosomes. Phylogenetic relationship analysis revealed that SmCCD classified four subfamilies, including SmCCD4, 7, 8, NCED; members same subfamily show similar gene structures tertiary structures. The interspecific collinearity with plant species, such as Arabidopsis thaliana Oryza sativa was analyzed. Cis-elements demonstrated majority stress response-, light growth-, development-related. expression pattern expressed analyzed tissues. Furthermore, SmCCD4 varied their levels under treatment MeJA, YE, ABA, indicating potential function metabolism general, study provides systematic lays foundation for uncovering regulation
