General Information

General Information Comment Organism
evolution phylogenetic analysis, AtSASP and its putative orthologues clustering in one discrete group of subtilisin proteases in which no other Arabidospsis subtilisin protease is present. The enzyme function is at least partially conserved between Arabidopsis thaliana and Oryza sativa Arabidopsis thaliana
malfunction at maturity, enzyme knockout sasp-1 plants produce 25% more inflorescence branches and siliques, mostly due to an increased number of second and third order branches, than either the wild-type or the rescued lines Arabidopsis thaliana
additional information occurrence of the two variant forms of AtSASP can be due to posttranslational modifications Arabidopsis thaliana
physiological function the enzyme downregulates branching and silique production during monocarpic senescence Arabidopsis thaliana
