The role of cyclic nucleotides in the model plant arabidopsis

Adenylyl cyclases (ACs) catalyze the formation of adenosine3',5'-cyclic monophosphate (cAMP) from adenosine 5'-triphosphate (ATP). The Arabidopsis genome contains two genes, At3g14460 (AC1) and At3g14470 (AC2) which have an aminoterminal nucleotide binding domain and sequence homolo...
