Zygotic genome activation and parent-of-origin gene function in Arabidopsis embryogenesis

Resumen
In plants as in animals, the zygote is formed by the union of the egg and sperm. In animals, there is broad agreement that maternal transcripts and proteins inherited from the egg regulate early embryo development until the zygotic genome becomes transcriptionally active, a process termed the maternal to zygotic transition. In animals, this transition can last from several hours up to several days, depending on the species.
In plants, the timing of the maternal to zygotic transition is not yet understood, with some studies arguing that zygotic genome occurs immediately after fertilization, and others arguing that the zygotic genome is transcriptionally silent for the first few days after fertilization.
In my seminar, I will present genetic and genomic studies to understand the timing of zygotic genome activation in Arabidopsis and the contributions of the maternal and paternal genomes to the zygotic transcriptome. I will also discuss some of our recent results on epigenetic mechanisms for regulation of maternal and paternal allele transcription in the zygote, and functional roles for paternal alleles in early embryogenesis.
