Background The petal senescence of ethylene insensitive species has not been
investigated thoroughly while little is known about the temporal and tissue specific …

Senescence represents the last stage of floral development and is an active process that
requires gene transcription and protein translation. A genetically controlled senescence …

Main conclusion Numerous transcription factor genes and methylation-related genes were
differentially expressed in senescent petals compared with control petals. Abstract Studying …

The genetic regulatory mechanisms that govern natural corolla senescence in petunia are
not well understood. To identify key genes and pathways that regulate the process, we …

Several families of transcription factors (TFs) control the progression of senescence. Many
key TFs belonging to the WRKY family have been described to play crucial roles in the …

Flower senescence is a fascinating natural process that represents the final developmental
stage in the life of a flower. Plant hormones play an important role in regulating the timing of …

Background In many species floral senescence is coordinated by ethylene. Endogenous
levels rise, and exogenous application accelerates senescence. Furthermore, floral …

Floral senescence involves an ordered set of events coordinated at the plant, flower, organ
and cellular level. This review assesses our current understanding of the input signals …

Petals and leaves share common evolutionary origins but perform very different functions.
However, few studies have compared leaf and petal senescence within the same species …

Flowers of ethylene-sensitive ornamental plants transformed with ethylene-insensitive 1-1
(etr1-1), a mutant ethylene receptor first isolated from Arabidopsis, are known to have longer …
