Abstract
A cDNA clone encoding a lipase that is upregulated in senescing leaves and flower petals has been isolated by screening an expression library. The abu ndance of the lipase mRNA increases as flowers and leaves begin to senesce, and expression of the gene is also induced by treatment withethylene, Tran sgenic Arabidopsis plants in which levels of the senescence-induced lipase protein have been reduced show delayed leaf senescence.
