Cold-Specific Induction of a Dehydrin Gene Family Member in Barley.

abstract：:Previous work (D.P. Delmer, J. Pear, A. Andrawis, D. Stalker [1995] Mol Gen Genet 248: 43-51) has identified a gene in cotton (Gossypium hirsutum), Rac13, that encodes a small, signal-transducing GTPase and shows high expression in the fiber at the time of transition from primary to secondary wall synthesis. Since Rac...
