curculin-like (mannose-binding) lectin family protein, low similarity to ser/thr protein kinase from Zea mays; contains Pfam lectin (probable mannose binding) domain PF01453 but not the protein kinase domain of the Z. mays protein.

 AT1G19310

1.51

RING/U-box superfamily protein

 UGT76C2

1.78

Encodes a cytokinin N-glucosyltransferase that is involved in cytokinin homeostasis and cytokinin. Expression is induced by ABA, mannitol and drought stress.
