This study shows ABI4 protein stability is regulated by stress, ABA, and phosphorylation at Serine 114, with MAP kinases affecting both transcript and protein levels.

This study shows that PUB46 and PUB48 in Arabidopsis have partially redundant roles in drought response, with additional specific functions when both are inhibited.

This study shows that phosphorylation of Serine114 in ABI4 is essential for its activity, affecting ABA, glucose, salt stress responses, and lateral root development.

This paper shows that overexpressing AtPUB46 in Arabidopsis improves drought and oxidative stress tolerance through reduced stomatal size and altered stress pathway activity.
