Expression of ethylene biosynthetic and receptor genes in rose floral tissues during ethylene-enhanced flower opening
Ethylene production, as well as the expression of ethylene biosynthetic (Rh-ACS1-4 and Rh-ACO1) and receptor (Rh-ETR1-5) genes, was determined in five different floral tissues (sepals, petals, stamens, gynoecia, and receptacles) of cut rose (Rosa hybrida cv. Samantha upon treatment with ethylene or the ethylene inhibitor 1-methylcyclopropene (1-MCP). Ethylene-enhanced ethylene production occurr...
متن کاملEthylene Effects
Biological Attributes of Ethylene: Colorless gas at biological temperatures. Naturally occurring organic compound. Readily diffuses from tissue. Produced from methionine via ACC by a highly regulated metabolic pathway. Key enzymes are ACC synthase and ACC oxidase. C2H4 synthesis is inhibited by C2H4 in vegetative and immature reproductive tissue. C2H4 synthesis is promoted (autocatalytic) by C2...
متن کاملComparison of Plant Growth Regulators and Exogenous Ethylene Effects on Two Types of Cut Carnation (Dianthus caryophyllus L.)
The main object of this study is to investigate the effect of plant growth regulators on the prolongation of vase life of two kinds of cut carnation under normal and ethylene. Carnation is one of the most popular flowers that has a short life due to its sensitivity to ethylene. Also, the effect of plant growth regulators on several physiological traits under ethylene stress and normal condition...
متن کاملEnhanced Ethylene Emissions from Red and Norway
Acidic cloudwater is believed to cause needle injury and to decrease winter hardiness in conifers. During simulations of these adverse conditions, rates of ethylene emissions from and levels of 1-aminocyclopropane-1-carboxylic acid (ACC) in both red and Norway spruce needles increased as a result of treatment with acidic mists but amounts of 1-malonyl(amino)cyclopropane-1carboxylic acid remaine...
متن کاملTranscriptional regulation of ethylene receptor and CTR genes involved in ethylene-induced flower opening in cut rose (Rosa hybrida) cv. Samantha.
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-methylcyclopropene), an ethylene action inhibitor, impeded it. Ethylene promoted ethylene production in petals, but 1-MCP did not inhibit this process. Of the four ethylene biosynthetic genes tested, Rh-ACS1 and R...
