An Ethylene-Induced Regulatory Module Delays Flower Senescence by Regulating Cytokinin Content.
In many plant species, including rose (Rosa hybrida), flower senescence is promoted by the gaseous hormone ethylene and inhibited by the cytokinin (CTK) class of hormones. However, the molecular mechanisms underlying these antagonistic effects are not well understood. In this study, we characterized the association between a pathogenesis-related PR-10 family gene from rose (RhPR10.1) and the ho...

متن کاملReversible inhibition of ethylene action and interruption of petal senescence in carnation flowers by norbornadiene.
The inhibitory effects of the cyclic olefin 2,5-norbornadiene (NBD) on ethylene action were tested in carnation (Dianthus caryophyllus L. cv White Sim) flowers. Treatment of flowers at anthesis with ethylene in the presence of 500 microliters per liter NBD increased the concentration of ethylene required to elicit a response (petal senescence), indicating that NBD behaves as a competitive inhib...
متن کاملA role for cytokinin in the onset of leaf senescence by ethylene in Arabidopsis
The expression of several Arabidopsis senescence-associated genes (SAGs) was found to be upregulated during leaf development of the onset of leaf death 9 mutant under standard growth conditions. Treatment of the mutant with ethylene resulted in a severe senescence response both phenotypically as well as on transcript level. A RNAi-based strategy to downregulate the expression of a SAG encoding ...
متن کاملRh-PIP2;1, a rose aquaporin gene, is involved in ethylene-regulated petal expansion.
Aquaporins are water channel proteins that facilitate the passage of water through biological membranes and play a crucial role in plant growth. We showed that ethylene treatment significantly reduced petal size, inhibited expansion of petal abaxial subepidermal cells, and decreased petal water content in rose (Rosa hybrida 'Samantha'). Here, we report the isolation of a plasma membrane aquapor...
