Guard Cell Signal Transduction.
Guard cells surround stomatal pores in the epidermis of plant leaves and stems. Stomatal pore opening is essential for CO2 influx into leaves for photosynthetic carbon fixation. In exchange, plants lose over 95% of their water via transpiration to the atmosphere. Signal transduction mechanisms in guard cells integrate hormonal stimuli, light signals, water status, CO2, temperature, and other en...
متن کاملEmerging themes of plant signal transduction.
The successful existence of all higher organisms is dependent upon their ability to coordinate complex developmental changes and to sense and respond to fluctuations in their surroundings. Responses to developmental and environmental cues occur by stimulus-response coupling: a stimulus is perceived by the cell, a signal is generated and transmitted (signal transduction), and a biochemical chang...
متن کاملPlant protein kinase families and signal transduction.
Enzymes of the eukaryotic protein kinase superfamily catalyze the reversible transfer of the gamma-phosphate from ATP to amino acid side chains of proteins. Protein kinase function can be counteracted by the action of phosphoprotein phosphatases. Phosphorylation status of a protein can have profound effects on its activity and interaction with other proteins. An estimated 1 to 3% of functional ...
متن کاملNetworking of phospholipases in plant signal transduction.
Phospholipases are activated in response to various cellular and environmental cues. Their activation can affect many cellular processes through their roles in signal transduction. Recent advances in the biochemical and molecular understanding of phospholipase D (PLD) have provided insights into potential networks of PLDs and other phospholipases in plants. PLDs are a family of heterogeneous en...
متن کاملSignal transduction in the plant immune response.
Complementary biochemical and genetic approaches are being used to dissect the signaling network that regulates the innate immune response in plants. Receptor-mediated recognition of invading pathogens triggers a signal amplification loop that is based on synergistic interactions between nitric oxide, reactive oxygen intermediates and salicylic acid. Alternative resistance mechanisms in Arabido...
