General Information

General Information Comment Organism
physiological function a strong loss-of-function mutation in PAPS1 causes a male gametophytic defect, whereas a weak allele leads to reduced leaf growth that results in part from a constitutive pathogen response. Polyadenylation of SMALL AUXIN UP RNA (SAUR) mRNAs depends specifically on PAPS1 function. The resulting reduction in SAUR activity in PAPS1 mutants contributes to their reduced leaf growth Arabidopsis thaliana
physiological function plants lacking both isoforms PAPS2 and PAPS4 function are viable with wild-type leaf growth Arabidopsis thaliana
