Article Abstract

The ABACUS1-2 μ (ABscisic Acid Concentration and Uptake Sensor 1-2 μ) and GPS1 (Gibberellin Perception Sensor 1) are direct Förster resonance energy transfer (FRET) biosensors that can be used to measure hormone levels in planta. We provide detailed protocols to image FRET biosensors under exogenously applied hormones in roots, either as a single time point or for treatment time courses before and after hormone application. A new, free, open-source analysis toolset for Fiji is introduced and used to get full 3D segmentation of images of nuclear localized FRET biosensors and calculate emission ratios on a per nucleus basis allowing in-depth analysis of biosensor data.

Staphylococcus aureus is ranked among the top five most common foodborne pathogens affecting public health and the economy worldwide. To improve detection and reduce diagnostic burdens, several detection methods from traditional culture-based techniques to biosensing platforms have evolved. Among several markers, surface proteins are considered to be the most important markers due to the specific roles they play in the survival and colonization of the bacterium on hosts.

The precise detection of ultralow-abundance biomarkers in biological matrices remains a critical challenge. Herein, we engineer a plasmonic-organic heterostructure for ultrasensitive detection of p53 gene in bio-samples. The heterostructure is formed by the self-assembly of polyethyleneimine (PEI)-functionalized covalent organic frameworks (COFs) and gold nanoparticles (Au NPs), named as COFs@PEI@Au NPs (C@P@A for short).

Förster resonance energy transfer (FRET) spectroscopy and microscopy are constantly expanding sensing techniques for analyzing biomolecular interactions. In addition to the biological recognition molecules and biological or chemical analytes, the most important components for designing FRET biosensing systems are the materials that constitute the FRET donor-acceptor pair. These FRET materials consist of small molecules, biological or chemical nanoscaffolds, or nanomaterials that function in the ultraviolet, visible, or infrared spectral range.

Plants compete for light by growing taller than their nearest competitors. This is part of the shade avoidance syndrome and is a response to an increase in far-red light (FR) reflected from neighboring leaves. The root responds to this shoot-sensed FR cue by reducing lateral root emergence.
