TL;DR: It is proved that transgenic plants overexpressing a gibberellin (GA)-responsive gene from beechnut, coding for a member of the GA3 stimulated in Arabidopsis (GASA) family, showed a reduced GA dependence for growth and improved responses to salt, oxidative, and heat stress at the level of seed germination and seedling establishment.

TL;DR: Double transgenic plants confirm the role of PYL8/RCAR3 by antagonizing FsPP2C1 function and demonstrating that Pyl8/ RCAR3 positively regulates ABA signaling during germination and abiotic stress responses.

TL;DR: It is suggested that negative regulation of ABA signaling by FsPP2C1 is a factor contributing to promote the transition from seed dormancy to germination during early weeks of stratification.

TL;DR: Findings suggest that both ABA and GA3 could be involved in theregulation of nucleic acid and protein metabolism during dormancy, acting antagonistically in these processes and, specifically, in the regulation of the synthesis of the two proteins that appear to play a role in the maintenance of dormancy in these seeds.

TL;DR: The results support the hypothesis that FsPP2C2 is a positive regulator of ABA and indicate the existence of potential cross-talk between ABA signaling and GA biosynthesis.
