Lysine 178-184 DNA topoisomerase I alpha Arabidopsis thaliana 116-125 9477323-6 1998 The strong allele, stm-5, is epistatic to mgo1, showing that the presence of meristematic cells is essential for MGO1 function. mgo1 42-46 DNA topoisomerase I alpha Arabidopsis thaliana 113-117 24992598-3 2014 Through a chemical genetics screen with a luciferase-based DNA methylation reporter, LUCL, we found that camptothecin, a compound with anti-cancer properties that targets DNA topoisomerase 1alpha (TOP1alpha) was able to de-repress LUCL by reducing its DNA methylation and H3K9me2 levels. lucl 85-89 DNA topoisomerase I alpha Arabidopsis thaliana 171-206 24992598-3 2014 Through a chemical genetics screen with a luciferase-based DNA methylation reporter, LUCL, we found that camptothecin, a compound with anti-cancer properties that targets DNA topoisomerase 1alpha (TOP1alpha) was able to de-repress LUCL by reducing its DNA methylation and H3K9me2 levels. Camptothecin 105-117 DNA topoisomerase I alpha Arabidopsis thaliana 171-206 24992598-3 2014 Through a chemical genetics screen with a luciferase-based DNA methylation reporter, LUCL, we found that camptothecin, a compound with anti-cancer properties that targets DNA topoisomerase 1alpha (TOP1alpha) was able to de-repress LUCL by reducing its DNA methylation and H3K9me2 levels. lucl 231-235 DNA topoisomerase I alpha Arabidopsis thaliana 171-206 26969721-5 2016 Loss of TOP1alpha function triggers DNA double-strand breaks in S-phase SSCs and results in their death, which can be partially reversed by the replenishment of SSCs mediated by ETHYLENE RESPONSE FACTOR115 In the quiescent center and root cap meristem, TOP1alpha is epistatic to RETINOBLASTOMA-RELATED (RBR) in the maintenance of undifferentiated state and the number of columella stem cells (CSCs). ethylene 178-186 DNA topoisomerase I alpha Arabidopsis thaliana 8-17 26969721-5 2016 Loss of TOP1alpha function triggers DNA double-strand breaks in S-phase SSCs and results in their death, which can be partially reversed by the replenishment of SSCs mediated by ETHYLENE RESPONSE FACTOR115 In the quiescent center and root cap meristem, TOP1alpha is epistatic to RETINOBLASTOMA-RELATED (RBR) in the maintenance of undifferentiated state and the number of columella stem cells (CSCs). ethylene 178-186 DNA topoisomerase I alpha Arabidopsis thaliana 253-262
