Light- and dark-grown Potamogeton pectinatus, an aquatic macrophyte, make no ethylene (ethene) but retain responsiveness to the gas
Plants of Potamogeton pectinatus L., growing rapidly from small tubers in the dark or from 12-week-old light-grown plants, contained high concentrations of the ethylene precursor 1-amino-cyclopropane- 1-carboxylic acid (ACC) (4.8 – 25.6 nmol g-1 fresh weight). However, ethylene (ethene) production w...

by flame ionization gas chromatography sensitive to <0.04 µmol
m-3. Seedlings of pea
(Pisum sativum L.) of similar size produced ethylene in
readily detectable amounts although concentrations of endogenous ACC
concentrations were much smaller than in P. pectinatus.
Large amounts of exogenous ACC (10 mM) supplied for 4 h or 15 h failed to
induce ethylene production in dark-grown P. pectinatus
but raised it marginally above background levels in light-grown shoots. In
contrast, a substantial effect was seen in pea shoots. When 25 mM ACC was
supplied, a small amount of ethylene was released by dark-grown
P. pectinatus but the rate was less than 0.5% of
that measured from pea plants treated similarly. An absence of ACC oxidase
enzyme activity in extracts of P. pectinatus showed that
the last step in the ethylene biosynthetic pathway is constitutively arrested
in mature plants grown in the light and in young plants regenerating from
tubers in the dark. Despite an inherent inability to synthesise ethylene,
P. pectinatus remained responsive to applied ethylene.
Leaf extension and adventitious rooting from stem nodes were promoted strongly
by 0.41 mmol m-3 ethylene, whereas applications of ACC
had no effect on growth or development.</description><identifier>ISSN: 0310-7841</identifier><identifier>ISSN: 1445-4408</identifier><identifier>EISSN: 1446-5655</identifier><identifier>DOI: 10.1071/PP97104</identifier><identifier>CODEN: AJPPCH</identifier><language>eng</language><publisher>Collingwood: Commonwealth Scientific and Industrial Research Organization</publisher><subject>1-aminocyclopropane-1-carboxylic acid ; adventitious roots ; Biological and medical sciences ; dark ; enzyme activity ; ethylene ; ethylene production ; Fundamental and applied biological sciences.
