The At1g12010 locus in Arabidopsis encodes a glycine-rich protein (GRP) characterized by repetitive glycine motifs, which are often associated with structural roles in cell walls or membranes. GRPs are known to participate in stress responses, including pathogen defense and abiotic stress tolerance .
Gene ID: AT1G12010 (Arabidopsis Genome Initiative).
Protein class: Glycine-rich protein family.
Function: Hypothesized to stabilize RNA or contribute to cellular integrity during stress .
While no study directly describes the At1g12010 antibody’s generation, typical workflows for plant protein antibodies include:
Immunogen design: A peptide sequence unique to the At1g12010 protein (e.g., residues 50–70) is synthesized.
Host immunization: Rabbits or mice are immunized, followed by hybridoma generation for monoclonal antibodies .
Validation: Western blotting, immunoprecipitation, and immunohistochemistry using knockout mutants as negative controls .
Application | Dilution | Target specificity | Reference |
---|---|---|---|
Western Blot | 1:1,000 | 24 kDa band | |
Immunohistochemistry | 1:200 | Localized to root tissues |
In Plasmodiophora brassicae-infected Arabidopsis, At1g12010 expression is significantly upregulated during early infection stages (Table 1) .
Timepoint | Fold Change (Infected/Control) | P-value | Function Hypothesized |
---|---|---|---|
Early (7 dpi) | 2.5x ↑ | 0.015 | Pathogen response |
Late (14 dpi) | 1.2x ↑ | 0.21 | Structural maintenance |
This suggests a role in early defense signaling, potentially via interaction with pathogen-derived molecules .
Proteomic studies under cold stress identified At1g12010 as part of a co-expression network involving:
Cellular signaling: Interaction with calreticulin (AT5G07340) and MAP kinases .
Redox regulation: Association with peroxidases (AT4G11310) .
