Identification and characterization of signal components in early ABA signaling in Arabidopsis
<p>The phytohormone abscisic acid (ABA) regulates growth, development, and response to abiotic stress in plants. The core ABA signaling has three key components: ABA receptors PYRABACTIN RESISTANCE 1 and PYR1-Like protein (PYR1/PYLs), type 2C protein phosphatases (PP2Cs) and SNF1- related protein …

HOOKLESS1 REGULATES RESPONSES TO PATHOGENS AND ABSCISIC ACID THROUGH INTERACTION WITH MEDIATOR18 AND ACETYLATION OF WRKY33 AND ABI5 CHROMATIN
… senescence and flowering, seed insensitivity to ABA as well as plant defense responses including enhanced susceptibility to the necrotrophic pathogen Botrytis cinerea and the hemi-biotrophic pathogen Pseudomonas syringae DC3000 strain expressing the effector protein AvrRpm1 strain. We show that …

Farnesyltransferase: Gene Expression in Plants and Role in Plant Development
… with the role of FTase in abscisic acid (ABA) signaling. An unexpected pattern of GUS activity, not correlated with dividing cells or ABA signaling, was also observed in the transgenic plants. GUS activity was detected in vascular bundles adjacent to actively-growing tissues and in regions …

Understanding grapevine responses to abscisic acid
Abscisic acid (ABA) regulates various developmental processes and stress responses over both short (i.e. hours or days) and longer (i.e. months or seasons) time frames. To elucidate the transcriptional regulatory the early responses of grapevine (Vitis vinifera) responding to ABA, different organs …

Computational investigation of molecular recognition in plant hormone signal transduction
… exciting opportunities for targeting hormone signaling pathway to control plant activities. While substantial experimental studies have provided insights into plant signaling mechanism, it remains, in many cases, challenging to fully understand those protein-ligand and protein-protein …

Characterization of signaling pathways underlying key growth and development processes in Populus trichocarpa
… in plant metabolism and nutrient mobilization. ABA, a prominent plant phytohormone with known roles in the adaptation to stress has shown novel connections in the regulation of growth promoting complexes such as TOR through antagonistic regulatory actions of the SnRK2 protein kinase in …

Systems-Level Analysis of Rootstock–Scion Interactions in Apple Reveals Mechanisms of Cold Tolerance Under Field Frost Events
… transcription factors (MdCBF4, MdHSFC1), ABA signaling, ROS detoxification, and membrane remodeling. Co-expression network analysis revealed frost-associated hub genes and regulatory modules. Carbohydrate profiling showed that B.9 maintained more stable soluble sugars—such as sucrose, …

Quantitative Trait Loci Analysis of Low Temperature Responses in Grapevine F2 Population
… candidate genes associated with calcium signaling, ethylene signaling, ABA signaling, cellular metabolism and dehydration response were found underlying the 1.5 LOD interval of these QTLs. The bud break phenology was studied at three chilling periods to identify bud break related QTL. Bud …

The role of NAD+ compartmentation and dynamics in Arabidopsis thaliana
… associated with the induction of abscisic acid (ABA)-responsive genes. Additionally, NAD+ feeding of aba- 2 and ost1 seedlings, impaired in ABA synthesis and ABA signaling, respectively, did not impact on stomatal number, whereas the inhibition of ABA synthesis rescued the stomatal phenotype in …
