Methionine-induced Ethylene Production by Penicillium digitatum.
Shake cultures, in contrast to static cultures of Penicillium digitatum grown in liquid medium, were induced by methionine to produce ethylene. The induction was concentration-dependent, and 7 mM was optimum for the methionine effect. In the presence of methionine, glucose (7 mM) enhanced ethylene production but did not itself induce ethylene production. The induction process lasted several hou...
متن کاملFactors affecting the production of ethylene by Penicillium digitatum.
Etlhylene production by the greenl miold of citrus, Plenicilliutmit digitatuimit Sacc., has beeni investigated by a number of workers (1), but its pathway of biosynthesis and importance in fungal metabolism have yet to be defined. Factors affecting growth of the funglus have been studied intensively and a satisfactory medium has been developed (2, 7). The importance of zinc and yeast extract as...
متن کاملCharacterization of the Phosphate-mediated Control of Ethylene Production by Penicillium digitatum.
Characterization of the phosphate effect on ethylene production by Penicillium digitatum is reported. A low level of phosphate (0.001 millimolar) was about 200 to 500 times as effective as a high phosphate level (100 millimolar) in stimulating ethylene production and the stimulation was readily reversed by addition of phosphate. This phosphate effect did not operate in static cultures. The prec...
متن کاملIdentification of Ethylene as a Volatile Product of the Fungus Penicillium Digitatum.
Experiments reported independently by BIALE (1) and MILLER, WINSTON, and FISHER (8) revealed that the common green mold of citrus fruits, P. digitatum, produces a physiologically active emanation whose effects on plant tissue are the same as those caused by ethylene gas. It was shown by the latter authors and by BIALE and SHEPHERD (3) that this fungus produces this emanation whether grown on it...
متن کاملStimulation of ethylene production in apple tissue slices by methionine.
Methionine can induce more than a 100% increase in ethylene production by apple tissue slices. The increased amount of ethylene derives from carbons 3 and 4 of methionine. Only post-climacteric fruit tissues are stimulated by methionine, and stimulation is optimum after 8 months' storage. Copper chelators such as sodium diethyl dithiocarbamate and cuprizone very markedly inhibit ethylene produc...
