OsCAF2 contains two CRM domains and is necessary for chloroplast development in rice.

ABSTRACT:

Background

Chloroplasts play an important role in plant growth and development. The chloroplast genome contains approximately twenty group II introns that are spliced due to proteins encoded by nuclear genes. CAF2 is one of these splicing factors that has been shown to splice group IIB introns in maize and Arabidopsis thaliana. However, the research of the OsCAF2 gene in rice is very little, and the effects of OsCAF2 genes on chloroplasts development are not well characterized.

Results

In this study, oscaf2 mutants were obtained by editing the OsCAF2 gene in the Nipponbare variety of rice. Phenotypic analysis showed that mutations to OsCAF2 led to albino leaves at the seeding stage that eventually caused plant death, and oscaf2 mutant plants had fewer chloroplasts and damage
