title: Isolation and expression during pollen development of a tobacco cDNA clone encoding a protein kinase homologous to shaggy/glycogen synthase kinase-3.
abstract: We have isolated a tobacco (Nicotiana tabacum L.) cDNA clone encoding a putative serine/threonine protein kinase, which shows highest homology to previously described families of alfalfa and Arabidopsis protein kinases and to their homologues rat glycogen synthase kinase-3 and Drosophila shaggy kinases. Northern experiments showed that NtK-4 is expressed in all sporophytic tobacco tissues tested, as well as in gametophytic and embryogenic pollen.
