Journal ArticleDOI
Modulation of drought resistance by the abscisic acid receptor PYL5 through inhibition of clade A PP2Cs.
Julia Santiago,Americo Rodrigues,Angela Saez,Silvia Rubio,Regina Antoni,Florine Dupeux,Sang-Youl Park,José A. Márquez,Sean R. Cutler,Pedro L. Rodriguez +9 more
TL;DR: In this article, PYL5, PYL6 and PYL8 were identified as a cytosolic and nuclear ABA receptor that activates ABA signaling through direct inhibition of clade A PP2Cs.
Journal ArticleDOI
Gain-of-function and loss-of-function phenotypes of the protein phosphatase 2C HAB1 reveal its role as a negative regulator of abscisic acid signalling.
Angela Saez,Nadezda Apostolova,Miguel González-Guzmán,Mary Paz González-García,Carlos Nicolás,Oscar Lorenzo,Pedro L. Rodriguez +6 more
TL;DR: It is shown that constitutive expression of HAB1 in Arabidopsis under a cauliflower mosaic virus (CaMV) 35S promoter led to reduced ABA sensitivity both in seeds and vegetative tissues, compared to wild-type plants, providing new genetic evidence on the function of a PP2C in ABA signalling.
Journal ArticleDOI
Triple loss of function of protein phosphatases type 2C leads to partial constitutive response to endogenous abscisic acid.
Silvia Rubio,Americo Rodrigues,Angela Saez,Marie B. Dizon,Alexander Gallé,Tae-Houn Kim,Julia Santiago,Jaume Flexas,Julian I. Schroeder,Pedro L. Rodriguez +9 more
TL;DR: Results indicate that ABA response is finely tuned by the integrated action of these genes, which is required to prevent a constitutive response to endogenous ABA that might have a deleterious effect on growth and development in the absence of environmental stress.
Journal ArticleDOI
Enhancement of Abscisic Acid Sensitivity and Reduction of Water Consumption in Arabidopsis by Combined Inactivation of the Protein Phosphatases Type 2C ABI1 and HAB1
Angela Saez,Nadia Robert,Mohammad H. Maktabi,Julian I. Schroeder,Ramón Serrano,Pedro L. Rodriguez +5 more
TL;DR: This work has generated ABA-hypersensitive drought-avoidant mutants by simultaneous inactivation of two negative regulators of ABA signaling, i.e. the protein phosphatases type 2C (PP2Cs) ABI-INSENSITIVE1 (ABI1) and HAB1, and suggests that fine tuning of A BA signaling can be attained through combined action of PP2Cs.
Journal ArticleDOI
HAB1–SWI3B Interaction Reveals a Link between Abscisic Acid Signaling and Putative SWI/SNF Chromatin-Remodeling Complexes in Arabidopsis
TL;DR: The results uncover SWI3B as a novel positive regulator of ABA signaling and suggest that HAB1 modulates ABA response through the regulation of a putative SWI/SNF chromatin-remodeling complex.
