determination of the genetic interactions between AtBXL1 and known MSC-related transcription factors, overview Arabidopsis thaliana

Protein Variants

Protein Variants Comment Organism
additional information identification of a T-DNA insertion mutant of AtBXL1, that shows mucilage release both patchy and slow, and the seeds display delayed germination. While developmental analysis of mutant seeds reveals no change in mucilage secretory cell morphology, changes in monosaccharide quantities are detected, suggesting the mucilage release defect results from altered mucilage composition. bxl1 Mutant seeds and antibody staining of developing seed coats reveal an increase in alpha-1,5-linked arabinans, phenotype, overview. Mutational analysis of the genetic interactions between AtBXL1 and MSC-related transcription factors Arabidopsis thaliana
