ADK1 — Cicer arietinum

Summary

LOC101508227 (CaADK1, ADK1) on chickpea chromosome 4 encodes an adenosine kinase, a member of the PfkB family of carbohydrate/purine kinases. The enzyme has adenosine kinase activity and is also associated with adenosylhomocysteinase and mRNA cap methyltransferase activities, copper and ATP binding, and localises to the cytosol, nucleus, vacuole, apoplast and plasmodesmata. CaADK1 is associated with adenosine and AMP salvage, mRNA capping, purine and secondary metabolism, DNA methylation-dependent heterochromatin assembly, post-transcriptional gene silencing, embryo development ending in seed dormancy, and signal transduction. It is associated with flower and seed coat colour, cytokinin content, shoot branching, seed yield, seed growth and development, and flowering time. Related genes in other species link the family to transmethylation, plant biomass, flowering time and shoot branching.
