The Arabidopsis SUCROSE UNCOUPLED‐6 gene is identical to ABSCISIC ACID INSENSITIVE‐4: involvement of abscisic acid in sugar responses

Abstract
In plants, sugars act as signalling molecules that control many aspects of metabolism and development. Arabidopsis plants homozygous for the recessive sucrose uncoupled‐6 (sun6) mutation show a reduc...
