nels are also important in FSH signal transduction system in Sertoli cells [32 49]. The decrease of resting calcium concentration and blockade of the FSH-induced rise when Sertoli cells are incubated in calcium-free medium is consistent with the requirement for external calcium in resting conditions as well as in FSH signal transduction mechanism.

Calcium and Signal Transduction in Plants: Critical Reviews ...

Environmental and hormonal signals control diverse physiological processes in plants. The mechanisms by which plant cells perceive and transduce these signals are poorly understood. Understanding biochemical and molecular events involved in signal transduction pathways has become one of the most active areas of plant research.

The role of cytosolic Ca2+ in signal transduction in stomatal guard cells of Commelina communis was investigated using fluorescence ratio imaging and photometry. By changing extracellular K+ extracellular Ca2+ or treatment with Br-A23187 substantive increases in cytosolic Ca2+ to over 1 micromolar accompanied stomatal closure.

Calcium Signaling in Plant Endosymbiotic Organelles ...

INTRODUCTION. Calcium ion (Ca 2+) plays pivotal roles in the physiology and biochemistry of all organisms.However Ca 2+ is also toxic to cells: at high concentrations Ca 2+ and phosphorus can form an insoluble precipitate of calcium phosphate which interferes with nucleic acid metabolism.

Plant Protein Kinase Families and Signal Transduction'

tures of the five major plant protein kinase families will be discussed and the similarities and differences between the plant protein kinases and the other eukaryotic protein ki- nases will be highlighted. This analysis has led to some interesting observations regarding signal transduction in higher plants.

Ca2+ signals are a core regulator of plant cell physiology and cellular responses to the environment. The channels pumps and carriers that underlie Ca2+ homeostasis provide the mechanistic basis for generation of Ca2+ signals by regulating movement of Ca2+ ions between subcellular compartments and between the cell and its extracellular environment. The information encoded within the Ca2 ...

The role of calcium in plant signal transduction under ...

The role of Ca as a secondary messenger is well known in both plant and animals with the concentration of Ca in plant cells being delicately balanced between the cytosol cellular compartments such as vacuoles endoplasmic reticulum and the cell wall. 1 Changes in intracellular Ca levels are involved in the transduction of many intracellular signals used to regulate the developmental and environmental responses of plants. Ca is never actively excreted out of plant cells and its ...
