Title

Other claims from this paper (10)

Observation Seven carnation petal ubiquitin cDNAs were cloned.
Observation DcUbq1, DcUbq2 and DcUbq3 encoded five-monomer polyubiquitins.
Observation DcUbq4 encoded a three-monomer polyubiquitin.
Observation DcUbq5, DcUbq6 and DcUbq7 encoded monomers.
Observation The 3′-UTRs formed three sequence groups, with DcUbq1 and DcUbq2 each specific and a common DcUbq3–7 group.
Observation DcUbq1 and DcUbq2 transcript levels fluctuated during petal opening.
Observation DcUbq3–7 transcripts were stable during opening except for a late increase.
Observation DcUbq1 and DcUbq2 transcript levels rose late in flower senescence.
Mechanism The authors suggest ubiquitin gene expression is associated with petal growth and wilting through protein degradation.
Method / resource DcUbq3–7 transcripts served successfully as a normalization standard in senescing carnation petals.
