Use of CRISPR-Cas9 Revealed OsCAF1 Influences Chloroplast Development in RiceSeptember 11, 2019
The chloroplast splicing and ribosome maturation (CRM) domain proteins have functions in the splicing of chloroplast gene introns. Several CRM domain proteins have been discovered to be involved in chloroplast development in many plants, but their functions in rice are still yet to be known. To elucidate more on this, scientist Qiang Zhang from Chinese Academy of Sciences and colleagues used CRISPR-Cas9 technology. The results were reported in the International Journal of Molecular Sciences.
Albino mutants oscaf1 were generated through the editing of OSCAF1 with two CRM domains using CRISPR-Cas9. The mutants eventually died at seedling stage. It was observed that the mutants had fewer chloroplast numbers and damaged chloroplast structures.OsCAF1 was found in the chloroplast, and were in high amounts in green tissues. Furthermore, OsCAF1 promoted the splicing of group IIA and group IIB introns, which could be influenced by its interaction with OsCRS2.
