Blue Light Receptor PHR2‐Mediated Spectrum Antiviral Immunity

Advanced Science, EarlyView.
Blue light suppresses RBSDV through the blue‐light receptor ZmPHR2, which interacts with ZmISP in chloroplasts to trigger ROS burst and antiviral defense. The viral effector P6 enhances ZmPHR2–ZmISP interaction, alters their distribution, and suppresses ROS.

Living Electronics: Microbial Metabolism as Batteries, Resistors, and Capacitors

Advanced Electronic Materials, EarlyView.
Three microorganisms are assigned the three elementary roles of a circuit on one sheet of paper. Dormant Bacillus subtilis spores germinate to switch the power source on; a photosynthetic Synechocystis biofilm sets resistance by the color and intensity of light; and a respiring Shewanella oneidensis biofilm stores charge. Together they form a printable

A system for imaging variable chlorophyll fluorescence of aquatic phototrophs [PDF]

Ophelia, 2004
Abstract We describe a modular imaging system for mapping the variable chlorophyll fluorescence of photosynthetic organisms and tissues in the aquatic environment. The system is based on an array of blue LED's (470 nm) for excitation of chlorophyll and a modulated CCD camera equipped with a long-pass filter for detection of chlorophyll fluorescence ...

Utilization of fluorescence images in chlorophyll in Cirebon waters, Indonesia

Borneo Journal of Marine Science and Aquaculture (BJoMSA), 2021
Satellite is one of the tools used to detect chlorophyll concentration. MODIS chlorophyll concentrations appears to be disturbed by colored dissolved organic matter (CDOM). The fluorescence approach can represent the chlorophyll concentration near the coast more accurately.

AI‐Enabled RGB Light‐to‐Frequency Sensor for Nondestructive Salinity Stress Monitoring in Medicinal Plants

Advanced Intelligent Systems, EarlyView.
A distributed wireless sensing framework enables noninvasive monitoring of plant salinity stress through leaf reflectance measurements acquired with portable optical sensors. The collected data are processed using TinyML‐based neural network models deployed at the edge, enabling accurate, real‐time, and low‐cost classification of salinity levels, while

Enhanced fluorescence imaging in chlorophyll-suppressed tobacco tissues using virus-induced gene silencing of the phytoene desaturase gene

BioTechniques, 2010
Fluorescence imaging in plants is unusually challenging because of the large amounts of photosynthetic pigments contained in green plant tissues. For example, chlorophyll can obstruct the penetration of light and has high levels of autofluorescence at ...
