Summary
| Editing Factor: | ECD1 |
| Synonym: | EMB2261; EMBRYO DEFECTIVE 2261 |
| Description: | Early Chloroplast Development 1 (ECD1), a chloroplast-localized pentatricopeptide repeat protein (PPR) belonging to the PLS subfamily; Inactivation of ECD1 in Arabidopsis led to embryo lethality, and abnormal embryogenesis occurred in ecd1/+ heterozygous plants; A decrease in ECD1 expression induced by RNAi resulted in seedlings with albino cotyledons but normal true leaves; In cotyledons of ECD1-RNAi plants, RNA-editing of rps14-149 (encoding ribosomal protein S14) was seriously impaired; In addition, dramatically decreased plastid-encoded RNA polymerase-dependent gene expression and abnormal chloroplast rRNA processing were also observed |
