Transcriptome analysis of khd-1, spen-1 and hub1-4 Arabidopsis mutants. Transcriptome analysis of khd-1, spen-1 and hub1-4 Arabidopsis mutants

HISTONE MONOUBIQUITINATION1 (HUB1) and its ortholog HUB2 regulate expression of genes involved in flowering, dormancy and circadian clock. HUB1 and HUB2 interact with two RNA-binding proteins KHD and SPEN. Phenotype analysis of the knock-down khd-1, knock-out spen-1, and knock-out hub mutants suggested that KHD and SPEN may contribute to flowering- and circadian clock-related functions that are also target of HUB1/2 activity. Transcriptome analysis was performed using RNA extracted from shoot apices of 10-day-old seedlings. After library preparation by TruSeq, RNA was sequenced on the Illumina HiSeq.
