TITLE=Nitric Oxide Enables Germination by a Four-Pronged Attack on ABA-Induced Seed Dormancy JOURNAL=Frontiers in Plant Science VOLUME=Volume 9 - 2018 YEAR=2018 URL=https://www.frontiersin.org/journals/plant-science/articles/10.3389/fpls.2018.00296 DOI=10.3389/fpls.2018.00296 ISSN=1664-462X ABSTRACT=Nitric oxide (.NO) is known to attenuate dormancy and promote germination, a function that seemingly depends on crosstalk with the abscisic acid (ABA) signalling network. In the past two years, a number of independent studies have revealed that .NO gates the ABA signalling network at multiple steps, ensuring redundant and effectively irreversible control of germination. Here we summarise the recent studies, and propose a model of the multiple functions of .NO in seed dormancy.
