The At4g03540 gene encodes a dirigent-like protein involved in disease resistance mechanisms in Arabidopsis thaliana. Dirigent proteins are known to mediate lignan biosynthesis and plant defense responses . The protein’s structure includes conserved domains typical of dirigent family members, which facilitate stereoselective coupling of monolignol radicals during lignin formation .
ELISA: Used for quantitative detection of the At4g03540 protein in plant extracts .
Western Blot: Validates protein expression levels in transgenic or mutant Arabidopsis lines .
Functional Studies: Investigates the role of dirigent-like proteins in plant-microbe interactions and lignin biosynthesis .
The immunogen is a recombinant protein derived from the full-length At4g03540 sequence. Specificity is confirmed through:
Cross-reactivity tests against related dirigent proteins.
Immunoblotting using Arabidopsis wild-type and mutant samples .
