Transcriptomics analysis of developing wild type and val1 mutant Arabidopsis embryos

ABSTRACT: Developing Arabidopsis seeds accumulate oils and seed storage proteins synthesized by the pathways of primary metabolism. Seed development and metabolism are positively regulated by transcription factors belonging to the LAFL regulatory network. The VAL gene family encodes repressors of the seed maturation program in germinating seeds, although they are also expressed during seed maturation. VAL1 functions as a repressor of seed metabolism, as val1 mutant seeds accumulated elevated levels of storage proteins compared to the wild type. Two VAL1 splice variants were identified through RNA sequencing analysis: a full-length and a truncated form lacking the plant-homeodomain-like domain associated with epigenetic repression. None of the transcripts encoding the core LAFL network transcrip
