additional information | introduction of the stay-green gene from Festuca pratensis enzyme activity related to chlorophyll catabolism are analyzed in senescing leaves of wild-type Lolium temulentum and compared with mutant stay line leaves. During senescence of wild-type leaves chlorophylls a and b are continuously catabolised to colourless products and no other derivatives are observed, whereas in mutant stay-green leaves there is an accumulation of dephytylated and oxidised catabolites including chlorophyllide a, phaeophorbide a and 132 OH-chlorophyllide a. Pigment analysis, overview. The stay-green phenotype is not due to a mutation in RCCR in Lolium temulentum | Lolium temulentum |
