The Arabidopsis ABSCISIC ACID-INSENSITIVE2 (ABI2) and ABI1
Abscisic acid (ABA) mediates seed maturation and adaptive responses to environmental stress. In Arabidopsis, the ABA-INSENSITIVE1 (ABI1) protein phosphatase 2C is required for proper …
The abi1-1 mutation blocks ABA signaling downstream of cADPR …
Arabidopsis thaliana abscisic acid insensitive 1-1 (abi1-1) is a dominant mutant that is insensitive to the inhibition of germination and growth by the plant hormone, abscisic acid (ABA). The …
The ABI1 and ABI2 protein phosphatases 2C act in a negative …
The Arabidopsis ABI1 and ABI2 genes encode two protein serine/threonine phosphatases 2C (PP2C). These genes have been originally identified by the dominant mutations abi1--1 and …
The abi1‐1 mutation blocks ABA signaling downstream of cADPR action ...
2003年4月23日 · Arabidopsis thaliana abscisic acid insensitive 1-1 (abi1-1) is a dominant mutant that is insensitive to the inhibition of germination and growth by the plant hormone, abscisic …
Low ABA concentration promotes root growth and hydrotropism …
Here, we demonstrate that ABI1, a key component of clade A PP2Cs in ABA signal transduction pathway, directly interacts with the C-terminal R domain of AHA2 and dephosphorylates Thr …
ABA‐deficient (aba1) and ABA‐insensitive (abi1‐1, abi2‐1) …
2001年12月25日 · To assess stomatal insensitivity of the abi1-1 and abi2-1 mutants to ABA, we performed a gas-exchange analysis of ABA response in these mutants versus wild-type Ler …
Degradation of the ABA co-receptor ABI1 by PUB12/13 U-box E3 …
2015年10月20日 · Here, we report that ABI1 (ABA-INSENSITIVE 1) can interact with the U-box E3 ligases PUB12 and PUB13, but is ubiquitinated only when it interacts with ABA receptors in …
Arabidopsis abi1-1 and abi2-1 phosphatase mutations reduce …
Arabidopsis abi1-1 and abi2-1 phosphatase mutations reduce abscisic acid-induced cytoplasmic calcium rises in guard cells. Elevations in cytoplasmic calcium ( [Ca (2)+] (cyt)) are an …
Structural basis of abscisic acid signalling - Nature
2009年10月23日 · Our results reveal the structural basis of the mechanism of (+)-ABA-dependent inhibition of ABI1 by PYL1 in ABA signalling. The phytohormone ABA has central roles in the …
Degradation of the ABA co-receptor ABI1 by PUB12/13 U-box E3 …
2015年10月20日 · Here, we report that ABI1 (ABA-INSENSITIVE 1) can interact with the U-box E3 ligases PUB12 and PUB13, but is ubiquitinated only when it interacts with ABA receptors in …
