| Title |
Epigenetic reprogramming orchestrates transcriptional responses in shade avoidance syndrome of Arabidopsis |
| Organism |
Arabidopsis thaliana |
| Experiment type |
Expression profiling by high throughput sequencing
|
| Summary |
For shade-intolerant plants, changes in light quality indicative of competition from neighboring plants trigger shade avoidance syndrome (SAS). PYHTOCHROME-INTERACTING FACTOR 7 is the major transcriptional regulator of SAS in Arabidopsis. However, the epigenetic reprogramming under shade is poorly understood. To identify the histone chaperone ASF1 and HIRA function during SAS, we performed transcriptome deep sequencing (RNA-seq) to search for differentially expressed genes (DEGs) by comparing transcript levels between Col-0 and pif7-1, asf1ab, or hira-1 seedlings during white light and shade conditions. Our data shown that histone chaperone ASF1, through interacting with PIF7 and helping of HIRA, positively regulates shade-induced genes expression.
