Rice debranching enzyme isoamylase3 facilitates starch metabolism and affects plastid morphogenesis.

Plant & cell physiology - 1 Jun 2011

Yun Min-Soo, Umemoto Takayuki, Kawagoe Yasushi

Abstract excerpt

Debranching enzymes, which hydrolyze α-1 and 6-glucosidic linkages in α-polyglucans, play a dual role in the synthesis and degradation of starch in plants. A transposon-inserted rice mutant of isoamylase3 (isa3) contained an increased amount of starch in the leaf blade at the end of the night, indicating that ISA3 plays a role in the degradation of transitory starch during the night. An epitope-tagged ISA3...
