The often rapid and synchronous programmed death of petal cells provides a model system
to study molecular aspects of organ senescence. The death of petal cells is preceded by a …

Flower longevity is one of the most important traits for ornamental plants. Ethylene plays a
crucial role in flower senescence in some plant species. In several species that show …

Abstract Ethylene (C2H4) is a gaseous hormone that affects many aspects of plant growth
and development. Ethylene perception requires specific receptors and a signal transduction …

The molecular mechanisms responsible for postpollination changes in floral scent emission
were investigated in snapdragon cv Maryland True Pink and petunia cv Mitchell flowers …

Petal senescence, one type of programmed cell death (PCD) in plants, is a genetically
controlled sequence of events comprising its final developmental stage. We characterized …

Ethylene biosynthesis in higher plants is regulated developmentally and environmentally. To
investigate the regulation of ACC synthase gene expression, the promoters of Arabidopsis …

In this work, the effect of ethylene on flower opening of cut rose (Rosa hybrida) cv. Samantha
was studied. However, although ethylene hastened the process of flower opening, 1-MCP (1 …

Continual exposure to 1.5 μl l− 1 ethylene caused 100% petal abscission within 2 h from
detached flowers of Pelargoniumpeltatum (L.)'Pink Blizzard'(ivy geranium) harvested just …

Pollination of many flowers leads to an increase in ethylene synthesis and flower
senescence. We have investigated the regulation of pollination-induced ethylene synthesis …

Senescence of plant organs is a genetically controlled process that regulates cell death to
facilitate nutrient recovery and recycling, and frequently precedes, or is concomitant with …
