Question

ABA is inactivated in plant cells by converting into?
A. Phaseic acid
B. Dihydrophaseic acid
C. ABA-glucosyl ester
D. All of the above

Answer 1

Answer:

D. All of the above

Explanation:

ABA can be converted to abscisyl-β-D- glucopuranoside, which is a reversible reaction, or it can be irreversibly converted to 6′-hydroxymethyl ABA, phaseic acid, or 4 8-dihydrophaseic acid. ABA can also be inactivated by the attachment of a glucose to the carboxyl group of ABA to form an ABA- glucose ester.
