As sessile organisms, plants face a variety of environmental challenges. Their reproduction
and survival depend on their ability to adapt to these stressors, which include water, heat …

We reported earlier that the tobacco early ethylene-responsive gene NtER1 encodes a
calmodulin-binding protein (Yang, T., and Poovaiah, BW (2000) J. Biol. Chem. 275, 38467 …

The Arabidopsis pseudo-response regulator, APRR1, has a unique structural design
containing a pseudo-receiver domain and a C-terminal CONSTANS motif. This protein was …

Background Second messengers have a key role in linking environmental stimuli to
physiological responses. One such messenger, guanosine 3′, 5′-cyclic monophosphate …

In higher plants, one of the major components of developmental processes is cell division.
The cell division cycle in plants is controlled by cyclins and cyclin-dependend kinases …

Appropriate stimulus-response coupling requires that each signal induces a characteristic
response, distinct from that induced by other signals, and that there is the potential for …

The role of the RNA degradation product 2′, 3′-cyclic adenosine monophosphate (2′,
3′-cAMP) is poorly understood. Recent studies have identified 2′, 3′-cAMP in plant …

“Signal transduction” is the term commonly used to define the diverse array of biochemical
mechanisms that regulate cellular physiology. The term “signal transduction” became …

According to current knowledge, cyclic nucleotides (cNMPs; both cAMP-adenosine 3′, 5′-
cyclic monophosphate and cGMP-guanosine 3′, 5′-cyclic monophosphate) act as key …

Adenylyl cyclases (ACs) and their catalytic product cAMP are regulatory components of
many plant responses. Here, we show that an amino acid search motif based on annotated …
