MERISTEM ACTIVITYLESS1 (MAL1) is involved in crown root development through the maintenance of meristem size in rice

Rice MERISTEM ACTIVITYLESS1 (MAL1) is an RING-H2 finger domain (RFD) contained gene. To elucidate the molecular functions of MAL1 during crown root development, we generated MAL1 knock-down transgenic plants. MAL1 RNA interfering (RNAi) transgenic plants exhibited shorter crown root length and less crown root number phenotype accompanied by low cell division rate.Here we sought to find the downstream genes of OsMAL1 in rice crown root tip Overall design: Genome-wide analysis of 5 day-after-germination crown root tip transcriptomes of MAL1 RNAi and corresponding wild type.
