1A Regulatory Module Controlling CA-Mediated Endosperm Cell Expansion Is Critical for Seed Germination in Arabidopsis显示文摘A key component of seed germination is the interplay of mechanical forces governing embryo growth and the surrounding restraining endosperm tissue.Endosperm cell separation is therefore thought to play a critical role in the control of this developmental transition.Here we demonstrate that in Arabidopsis thaliana seeds,endosperm cell expansion is a key component of germination.Endosperm cells expand to accommodate embryo growth prior to germination.We show that this is an actively regulated process supported by spatiotemporal control of the cell expansion gene EXPANSIN 2 (EXPA2).The NAC transcription factors NAC25 and NACIL were identified as upstream regulators of EXPA2 expression,gibbereliinmediated endosperm expansion,and seed germination.The DELLA protein RGL2 repressed activation of the EXPA2 promoter by NAC25/NACIL.Taken together,our findings uncover a key role of the GA/ DELLA-NAC25/NACIL-EXPA2 network in regulating endosperm cell expansion to control the seed-toseedling transition.Rocio Sanchez-Montesino Laura Bouza-Morcillo Julietta Marquez Melania Ghita Salva Duran-Nebreda Luis Gomez Michael J.Holdsworth George Bassel Luis Onate-Sanchez 2019Molecular Plant2019,12,1:11
