*3.1. Plant Materials and Growth Conditions*

The *oscaf1* mutants were obtained using the CRISPR-Cas9 gene editing system in the *japonica* rice variety, Nipponbare, which was used as the WT. For chlorophyll content measurement and genetic material and RNA extraction, the WT and *oscaf1* plants were grown in growth chambers under a 16 h light and 8 h of a dark cycle at a constant temperature of 30 ◦C.
