Transcriptomical study on multipul pat mutants

The Arabidopsis genome encodes 3 PAT mRNA decapping factors: PAT1(AT1g79090), PATH1 (AT3g22270) and PATH2 (AT4g14990). We generated single, double and triple knockouts (KOs) of the three PATs by CRISPR/CAS9-mediated genome editing in the summ2-8 background to avoid immune activation. The 6 weeks-old soil-grown pat triple mutants exhibited markedly stunted growth compared to the other pat single or double mutants indicating functional redundancy of PATs in regulating plant development. To identify genes which affect different developmental programs regulated by PATs, we performed RNA-seq from plants of pat1-1path1-4path2-1summ2-8 and all single and double mutant combinations.
