Divergence in the ABA gene regulatory network underlies
2022年5月2日 · Using this GRN, we reveal how rewiring of growth hormone subnetworks contributes to stark differences in the response to ABA in the extremophyte Schrenkiella parvula. Our study provides a model...
Architecture and dynamics of the abscisic acid gene regulatory …
2024年7月1日 · Many of these target genes are related to ABA signaling and, for example, the areb1 areb2 abf1 triple mutant was reported to be more susceptible to drought stress and less sensitive to ABA with respect to primary root growth, thus showing the importance of these TFs in ABA-related abiotic stress responses (Yoshida et al., 2010, 2015).
Genome-wide association study revealed genetic variations of ABA ...
In this study, we performed genome-wide association study (GWAS) to identify loci and genes associated with ABA sensitivity (reflected by seed germination inhibition by ABA) in a panel of 425 rice accessions. The seed germination assay revealed that Aus and indica rice had stronger ABA sensitivity than japonica rice.
Origin and evolution of genes related to ABA metabolism and its ...
2011年5月28日 · To examine the functional origin of ABA-related genes, we selected genes that show significant similarity to ABA-related genes in A. thaliana from Arabidopsis lyrata, Populus trichocarpa, Oryza sativa, Selaginella moellendorffii, and Physcomitrella patens. These highly similar genes are defined as homologous genes that are derived from a common ...
Origin and evolution of genes related to ABA metabolism and its ...
Here, we focused on 48 ABA-related Arabidopsis thaliana genes with 11 protein functions, and generated 11 orthologous clusters of ABA-related genes from A. thaliana, Arabidopsis lyrata, Populus trichocarpa, Oryza sativa, Selaginella moellendorffii, and Physcomitrella patens.
ABA signaling in stress-response and seed development
We review the recent progress on ABA signaling, especially ABA signaling for ABA-dependent gene expression, including the AREB/ABF regulon, SnRK2 protein kinase, 2C-type protein phosphatases and ABA receptors. Drought negatively impacts plant growth and …
Identification and characterization of core abscisic acid (ABA ...
2019年3月11日 · In the present study, we reported the identification and characterization of the core ABA signaling components in Setaria viridis, an emerging model plant for cereals and feedstock crops...
Genome-Wide Identification of the ABA Receptors Genes and …
2020年8月13日 · In this study, we identified 13 apple PYLs, termed MdPYL1-13, which could be classified into four groups according to structural features of the amino acid sequence. The gene structures and conserved motifs analysis found that the majority of MdPYL s had a similar number of exons and similar conserved motif profile in the same group.
ABA-responsive gene expression in response to drought stress: …
2019年1月1日 · Here, we highlight the studies of a family of dehydration-responsive element (DRE)-binding proteins (DREBs)/C-repeat (CRT)-binding factors (CBFs), which play key roles in ABA-independent gene expression in response to osmotic stress and confer significantly improved drought tolerance by genetic engineering approaches in a wide variety of plant ...
Arabidopsis LSH8 Positively Regulates ABA Signaling by …
2021年9月25日 · In addition, qPCR analysis found that under ABA treatment, LSH8 positively mediated the expression of downstream ABA-related genes of ABI3, ABI5, RD29B and RAB18. These results indicate that in Arabidopsis, LSH8 is a novel ABA regulator that could specifically change the expression pattern of APRs to positively mediate ABA responses.
