abstract：:Parent-of-origin dependent gene expression refers to differential activity of alleles inherited from the egg and sperm. In plants, zygotic genome activation (ZGA) and gene imprinting are two examples of this phenomenon, both of which occur during seed development. As its name implies, ZGA is a genome-wide process that...

Karrikin action in Arabidopsis requires the F-box protein MAX2 and the α/β-hydrolase KAI2, a paralogue of D14 that is required for perception of strigolactones (SL). SL response involves hydrolysis by D14, whereas karrikins bind to KAI2 witho...
