Abstract excerpt
To study the molecular mechanism of abscisic acid (ABA) regulation of root development, we screened the root growth of Arabidopsis mutants for sensitivity to ABA. ABA overly-sensitive 5 (ABO5/At1g51965) was identified, and was determined to encode a pentatricopeptide repeat protein required for cis-splicing of mitochondrial nad2 intron 3 (nad2 is one subunit in complex I). Under constant light conditions (24-h...
