Photon emissions from rice cells elicited by N-acetylchitooligosaccharide are generated through phospholipid signaling in close association with the production of reactive oxygen species

Functional imaging of biophoton responses of plants to fungal infection

“…In confirmation, spraying susceptible potato with arachidonic acid-an effective inducer of SAR and then challenging it with P. infestans resulted in a transient burst of light lasting for several hours. Kageyama et al (2006) documented thoroughly that elicitor-responsive photon emission from rice cells, induced by N-acetylchitooligosaccharide, occurred in a close relation with ROS generation. Putative signal transduction leading to elicitor-induced biophoton response was found to operate through phospholipid signalling.…”

Chitin Research Revisited

“…Photon emissions are elevated by environmental stresses and disease responses induced by pathogen attack. It has been shown that photon emissions from rice cells elicited by N -acetylchitohexaose are closely associated with the ROS-generating system, and are regulated by Ca2+ signaling and protein phosphorylation via phosphatidic acid (PA), an intermediate of phospholipid signaling [206]. Chito-oligosaccharide has shown inhibitory effects on tumor growth and metastasis of lung cancer in mice [207].…”

Ultraweak bioluminescence of maize under NaCl stress

“…It was also found that the UWL intensity attenuated gradually following with the increase of NaCl concentration, however the decrease speed increased. In some sress-treated plants, photon emissions were considered to be closely associated with the ROS-generating system, such as the rose under the stress of Cadmium (Cd) [15] , the wheat under the Stress of acid rain [16] , the herbivory-injured maize [17] and the rice cells elicited by N-acetylchitooligosaccharide [18] , moreover, the UWL all increased in the four cases above.…”
