A salt stress-responsive cytokinin receptor homologue isolated from Medicago sativa nodules
11 pages and 8 figuresA new cytokinin receptor homologue, MsHK1,
was isolated from Medicago sativa root nodules. MsHK1
expression was induced in alfalfa seedlings by exogenous
application of the cytokinin trans-zeatin. Transcript accumulation
was detected in diVerent plant organs. MsHK1
expression was induced by salt stress in alfalfa roots, leaves
and nodules, and transcript accumulation in the vascular
bundles pointed to a putative role in osmosensing for
MsHK1 and/or other close cytokinin receptor homologues.
Expression in the meristem and the invasion zone of the
nodule suggest a role for cytokinin receptors in cytokinin
sensing during nodule cell division and diferentationPeer reviewe
