Arabidopsis thaliana tanorexia-1 transcriptome profiling
Because the minimal chloroplast genome carries very limited genetic information, plants rely on signals sent from the chloroplasts to the nucleus for proper chloroplast development as well as for recovery from photoinhibition and response to photo-oxidative stress. In this study, we report the discovery of several factors involved in the reduced PQ pool-driven chloroplast-to-nucleus signaling process. High-throughput RNA-Seq expression profiling of tanorexia-1 (tnr-1) mutants in comparison to wild-type. From these experiments, we found out that the HSF and HAC1 transcription factors have broad effects on HL-driven nuclear gene expression. The DEAD-box RNA helicase 38, CRY1 and a previously uncharacterized G-patch domain-containing protein are also involved in the signaling.
