TL;DR: Results imply that plasma membrane-localized CBL1- and CBL9-CIPK23 complexes simultaneously regulate K+ transport processes in roots and in stomatal guard cells.

TL;DR: It is suggested that CBL1 functions as a positive regulator of salt and drought responses and a negative regulator of cold response in plants.

TL;DR: It is shown that CIPK3, a Ser/Thr protein kinase that associates with a calcineurin B–like calcium sensor, regulates ABA response during seed germination and ABA- and stress-induced gene expression in Arabidopsis.

TL;DR: Analysis of the cbl9 mutant plants showed enhanced expression of genes involved in ABA signaling, such as ABA-INSENSITIVE 4 and 5, and increased stress sensitivity in the mutant may be a result of both ABA hypersensitivity and increased accumulation of ABA under the stress conditions.

TL;DR: An APETALA2 (AP2) domain transcription factor is identified that serves as a repressor of ABA response during seed germination and ABA- and stress-induced gene expression in Arabidopsis (Arabidopsis thaliana) and increased stress sensitivity may result from hypersensitivity to ABA as ABA biosynthesis inhibitor rescued the stress hypersensitivity phenotype.
