High impact information on AS2


Biological context of AS2

  • The promoters for the AS1 and AS2 genes of pea were isolated, sequenced, and functionally dissected for their ability to confer regulated expression to the GUS reporter gene in transgenic tobacco [6].

Other interactions of AS2

  • Genetic interactions with a second gene, ASYMMETRIC LEAVES2 (AS2), indicate it acts at the same position in this hierarchy as AS1 [7].
