Fluorescent sensors can track the movement and distribution of the plant hormone abscisic acid in roots and leaves in Arabidopsis.

The calcium-dependent signaling pathway during ABA-dependent stomatal closure requires the calcium-independent pathway, and calcium signaling specificity is mediated by PP2C protein phosphatases.

Molecular signals from chloroplasts can synergistically interact with the plant hormone, abscisic acid (ABA), to regulate non-canonical signaling pathways mediating fundamental cellular processes including stomatal closure, seed dormancy and germination.

Fluorescent sensors for the hormone abscisic acid have been developed using a high-throughput platform, and used to monitor hormone dynamics in plant roots and leaves.

Arabidopsis plants slow growth and jettison leaves in response to drought via a mechanism that involves the transcription factor ABIG1.

A genome-wide view of the gene regulatory network governed by WRKY33 has identified key targets that negatively regulate ABA biosynthesis to provide immunity against infection by a necrotrophic fungus.

Arabidopsis seed germination can be repressed by a Pseudomonas factor.

Development of a real-time SnRK2 kinase FRET reporter reveals rapid SnRK2 activation by ABA, but not by Methyl-Jasmonate or elevated CO2, while directly demonstrating basal SnRK2 activity in guard cells.
