Ethylene-induced gene expression in carnation petals : relationship to autocatalytic ethylene production and senescence.
Exposure of carnation (Dianthus caryophyllus L.) flowers to ethylene evokes the developmental program of petal senescence. The temporal relationship of several aspects of this developmental program following treatment with ethylene was investigated. Exposure of mature, presenescent flowers to 7.5 microliters per liter ethylene for at least 6 hours induced petal in-rolling and premature senescen...
متن کاملRole of cytokinins in carnation flower senescence.
Stem and leaf tissues of carnation (Dianthus caryophyllus) plants appear to contain a natural antisenescence factor since removal of most of these tissues from cut carnation flowers hastened their senescence. However, kinetin (5-10 mug/ml) significantly delayed senescence of flowers with stem and leaf tissues removed. In addition, the life span of cut flowers with intact (30-cm) stems was incre...

متن کاملGenetic regulation of ethylene perception and signal transduction related to flower senescence
The plant hormone ethylene is involved in the regulation of a number of physiological and developmental processes and its role as a regulator of flower senescence is of particular economic importance in floriculture. The present review focuses on genetic control of flower senescence, particularly at the level of ethylene perception. Research in a number of flowering plants has indicated that fl...
متن کاملEthylene Production and Petal Wilting during Senescence of Cut Carnation (Dianthus caryophyllus) Flowers and Prolonging Their Vase Life by Genetic Transformation
Senescence of carnation flowers is characterized by autocatalytic ethylene production from petals and subsequent wilting of the petals. Recent studies on the regulation of ethylene production and wilting in senescing carnation petals revealed that (1) petal senescence is triggered by ethylene evolved from the gynoecium during natural senescence, (2) ethylene production in the gynoecium is induc...
