Transcriptional analysis highlights the molecular mechanisms associated with the senescence of florets in Gladiolus

Gladiolus 1 (Gladiolus spp.) florets exhibit low ethylene sensitivity. Accordingly, the wilting of their tepals is an ethylene-independent process. Both trehalose and cycloheximide can extend the vase life of gladiolus florets. Floral senescence is probably regulated by programmed cell death. However, senescence-related genes have not been thoroughly investigated, except in ethylene-sensitive species. In this project, we analyzed the expression of senescence-associated genes by conducting a transcriptome (RNA-seq) analysis.
