Cycloheximide inhibited ethylene production in excised pea root tips treated with high levels of indoleacetic acid (100 mum and 10 mum). In contrast, cycloheximide did not inhibit ethylene production induced by a lower concentration (1 mum) of indoleacetic acid unless it was added 2 hours before the indoleacetic acid treatment. These observations suggest that indoleacetic acid has two effects o...

A bstract. Kinetin in concentrations of 10-e to 10-4 M, stimuated ethylene production in 3 and 4-day old etiolated seedlings of Alaska pea (Pisucm sativum L. var. Ala-ka). Seedlings of other species responded similarly. The response to kinetin depended on the age of the seedlings. Kinetin alone did not influence ethylene production in 6-day old stem sections, but it greatly increased the enhanc...

What is it? Ethylene, or ethene in chemistry circles, is a colorless, flammable gas composed of two carbon atoms joined by a double bond. The chemical formula is C 2 H 4. Discovery as a biological agent… … In the late 19th Century, Dimitry Nikolayevich Neljubov, a young researcher at the Botanical Institute of St Petersburg, identified ethylene as the minor component of illuminating gas that ca...

BACKGROUND Metabolic engineering and synthetic biology of cyanobacteria offer a promising sustainable alternative approach for fossil-based ethylene production, by using sunlight via oxygenic photosynthesis, to convert carbon dioxide directly into ethylene. Towards this, both well-studied cyanobacteria, i.e., Synechocystis sp PCC 6803 and Synechococcus elongatus PCC 7942, have been engineered t...

To investigate the regulatory mechanism(s) of ethylene biosynthesis in fruit, transgenic tomatoes with all known LeEIL genes suppressed were produced by RNA interference engineering. The transgenic tomato exhibited ethylene insensitivity phenotypes such as non-ripening and the lack of the triple response and petiole epinasty of seedlings even in the presence of exogenous ethylene. Transgenic fr...

Differences in the mechanism of ethylene emanation of Ficus sycomorus L. during various stages of the fruit development were investigated by enclosing the figs in jars. Two distinct patterns of ethylene emanation were found. Pattern a. in stages not capable of ripening, neither spontaneously nor as a result of physiological treatment (nonripening stages A and C), ethylene concentration in the j...

Kinetin in concentrations of 10(-8) to 10(-4)m, stimulated ethylene production in 3 and 4-day old etiolated seedlings of Alaska pea (Pisum sativum L. var. Alaska). Seedlings of other species responded similarly. The response to kinetin depended on the age of the seedlings.Kinetin alone did not influence ethylene production in 6-day old stem sections, but it greatly increased the enhancing effec...
