Protein Variants

Protein Variants Comment Organism
additional information the trp2-8 and trp2-5 mutants have the most dramatically reduced accumulation of TSB mRNA (7% and 34% of wild type, respectively). In contrast, trp2-9 and trp2-10 plants have modest, but reproducible, enhancement of TSB RNA (28% and 40% higher than the wild type, respectively). TSB protein levels in the trp2 mutants vary from very low (13% of wild type for trp2-5 and 15% for trp2-8) to significantly greater than that of wild type (50-60% higher for trp2-10, trp2-100and trp2-102) Arabidopsis thaliana
