A Calmodulin Binding Protein from Arabidopsis Is Induced by Ethylene and Contains a DNA-Binding Motif

Molecular Characterization ofHbCDPK1, an Ethephon-Induced Calcium-Dependent Protein Kinase Gene ofHevea brasiliensis

“…28) Some calcium sensor genes regulated by ethylene have been isolated, such as LeCPK1, and LeCPK2 in tomato 13,23) and EICBP in Arabidopsis. 29) Both mechanical wounding and ethephon-stimulation can induce the biosynthesis of endogenous ethylene in H. brasiliensis.…”

Coping with Stresses: Roles of Calcium- and Calcium/Calmodulin-Regulated Gene Expression

“…Calmodulin binding transcription activators (CAMTAs; also referred to as signal-responsive proteins or ethylene-induced CaM binding proteins), were first discovered in plants in a screen for CaM binding proteins (Reddy et al, 2000;Poovaiah, 2000, 2002;Bouché et al, 2002). This family of TFs is highly conserved and possesses multiple domains.…”

“…CAMTAs have also been identified in the genomes of other multicellular organisms, including mammals, flies, and worms (Han et al, 2006;Song et al, 2006). In Arabidopsis, there are six CAMTAs (CAMTA1 to CAMTA6), whose transcript levels are highly responsive (up-or downregulated) to diverse stresses (Reddy et al, 2000;Poovaiah, 2000, 2002). CAMTA transcript levels are induced upon cold and heat treatment (CAMTA1 and CAMTA3-6) as well as salinity (CAMTA1-4 and CAMTA6) (Yang and Poovaiah, 2002).…”

Genes Encoding Calmodulin-binding Proteins in the Arabidopsis Genome

“…The newly identified CBPs include four hypothetical proteins, a protein kinase C substrate-like protein (PKC substrate-like), photosystem I-N subunit (PSI-N subunit), a pirin-like protein, four ACBP60 proteins (homologs of TCBP60), and a new member of auxininduced proteins, cyclic nucleotide-like gated channels (CNGCs) and ethylene-induced CBPs (EICBPs). The previously identified six clones include KCBP (20 -24), one TCBP60-like protein (25), two cyclic nucleotide gated channels (26 -28), an ethylene-induced CBP (29), and a glutamate decarboxylase (9,30,31) (Tables I and II).…”

“…terminus (29). The EICBP members show 40 -80% sequence identity with the N terminus parsley DNA-binding factor, CG-1 protein, (42) and 25-55% sequence similarity with the partial C terminus of the ethylene-induced protein (ER66) protein from tomato (43).…”
