MetabolomicsMetabolomics of red-light-induced stomatal opening in Arabidopsis thaliana: Coupling with abscisic acid and jasmonic acid metabolism
Environmental stimuli-triggered stomatal movement is a key physiological process that regulates CO2 uptake and water loss in plants. Stomata are defined by pairs of guard cells that perceive and transduce external signals, leading to cellular volume changes and consequent stomatal apertur...

MetabolomicsA Multi-Omics Analysis of Glycine max Leaves Reveals Alteration in Flavonoid and Isoflavonoid Metabolism Upon Ethylene and Abscisic Acid Treatment
Phytohormones are central to plant growth and development. Despite the advancement in our knowledge of hormone signaling, downstream targets, and their interactions upon hormones action remain largely fragmented, especially at the protein and metabolite levels. With an aim to get new insight into th...

ModelsGuard Cell Abscisic Acid Signaling
Plants both lose water and take in carbon dioxide through microscopic stomatal pores, each of which is regulated by a surrounding pair of guard cells. During drought, the plant hormone abscisic acid (ABA) inhibits stomatal opening and promotes stomatal closure, thereby promoting water conservation. ...

TranscriptomicsQuantitative transcriptomic analysis of abscisic acid-induced and reactive oxygen species-dependent expression changes and proteomic profiling in Arabidopsis suspension cells
Early rapid changes in response to the phytohormone abscisic acid (ABA) have been observed at the transcript level, but little is known how these transcript changes translate to changes in protein abundance under the same conditions. Here we have performed a global quantitative analysis of transcrip...

TranscriptomicsRNA-Seq of Sorghum bicolor 9d seedlings in response to osmotic stress and abscisic acid
This study utilized next generation sequencing technology (RNA-Seq) to examine the transcriptome of sorghum plants challenged with osmotic stress and exogenous abscisic acid (ABA) to elucidate those genes and gene networks that contribute to sorghum's tolerance to water-limiting environments with a ...

ProteomicsRebuilding core abscisic acid signaling pathways of Arabidopsis in yeast
The signaling pathway of the phytohormone abscisic acid (ABA) regulates responses towards abiotic stress such as drought and high osmotic conditions. The multitude of functionally redundant components involved in ABA signaling, poses a major challenge for elucidating the largely unresolved response ...

TranscriptomicsPYR/PYL receptors play a major role for regulation of transcriptional response to abscisic acid
Abscisic acid (ABA) is a key hormone for plant growth, development and stress adaptation. Perception of ABA through four types of receptors has been reported. We show here that impairment of ABA perception through the PYR/PYL/RCAR branch reduces vegetative growth and seed production, and leads to a ...

TranscriptomicsThe purine metabolite allantoin enhances abiotic stress tolerance through synergistic activation of abscisic acid metabolism
Purine catabolism is regarded as a housekeeping function that remobilizes nitrogen for plant growth and development. However, emerging evidence suggests that certain purine metabolites might contribute to stress protection of plants. Here, we show that in Arabidopsis, the intermediary metabolite all...

TranscriptomicsTranscriptome analysis of Arabidopsis thaliana G protein subunit mutants in response to abscisic acid (ABA)
Heterotrimeric G proteins mediate crucial and diverse signaling pathways in eukaryotes. To gain insights into the regulatory modes of the G protein and the co-regulatory modes of the G protein and the stress hormone abscisic acid (ABA), we generated and analyzed gene expression in G protein subunit ...

TranscriptomicsAn ABA response regulator unique to basal land plants required for the acquisition of desiccation tolerance
Purpose: The plant hormone abscisic acid (ABA) coordinates responses leading to desiccation tolerance in all land plants. RNA-seq was employed to obtain differential expression data in response to ABA, dehydration and mannitol treatments in wild-type tissue. This was compared against the targeted ge...
