▪ Abstract Plants harbor four families of kinases that have been implicated in Ca2+ signaling
(CDPKs, CRKs, CCaMKs, and SnRK3s). Although each family appears to respond to Ca2+ …

Environmental and hormonal signals control diverse physiological processes in plants. The
mechanisms by which plant cells perceive and transduce these signals are poorly …

Molecular procedures have been applied to isolate plant calmodulin-binding proteins. A
petunia cDNA expression library was screened with 35S-labeled recombinant calmodulin as …

Calcium/calmodulin-dependent kinases play vital roles in protein phosphorylation in
eukaryotes, yet little is known about the phosphorylation process of calcium/calmodulin …

Roots of many species respond to gravity (gravitropism) and grow downward only if
illuminated. This light-regulated root gravitropism is phytochrome-dependent, mediated by …

A study was conducted to determine the role of the plant pigment phytochrome in the signal
transduction pathway. Genetic, molecular and biochemical tests were conducted to …

Plants respond very efficiently to changes in the external environment and accordingly
regulate their growth and development. They also have the ability to sense stress conditions …

Abstract cDNA fragments corresponding to an apple (Malus domestica [L.] Borkh)
calmodulin-binding polypeptide have been isolated and characterized. The protein encoded …

Plant genomes encode a variety of protein kinases, and while some are functional
homologues of animal and fungal kinases, others have a novel structure. This review …

Roots of many species grow downward (orthogravitropism) only when illuminated. Previous
work suggests that this is a calcium-regulated response and that both calmodulin and …
