A push-pull method for collecting plant volatiles is described. The method allows for a comparison of volatiles induced by herbivore feeding, exogenous methyl jasmonate, and mechanical damage. This technique is also used to investigate the volatile response of undamaged branches to exposure to volatiles from herbivore-damaged branches within blueberry plants.

Salmonella invades and replicates inside intestinal epithelial cells both in Salmonella-specific vacuoles and free in the cytosol (hyper-replication). A high-throughput fluorescence microscopy-based protocol is described here to quantify the intracellular phenotypes of Salmonella by two complementary image analyses through ImageJ, reaching single-cell resolution and scoring.
FAQs
Anthocyanin profiles show which pigment compounds are present and how their composition varies among samples. Because these pigments contribute to blueberry color, profile differences can help relate appearance to cultivar, maturity, or processing. Comparing measurements across conditions may therefore reveal chemical changes that are not apparent from visual inspection alone and support evaluation of product quality.
These techniques address different analytical needs within the same investigation. High-performance liquid chromatography can separate constituents, mass spectrometry can assist with their identification, and spectrophotometry can provide measurements based on the sample’s chemical response. Selecting among them depends on whether the study emphasizes compound separation, constituent identification, or broader chemical measurement of tissues, juices, or products.
Measuring these constituent groups together connects chemical composition with important sample properties. Sugars and acids contribute to flavor, while pigments and phenolic compounds provide information about color and antioxidant-related composition. A combined profile also allows researchers to compare cultivars, maturity stages, or processed products using several chemically distinct indicators rather than relying on a single measurement.
A typical workflow begins by homogenizing the blueberry tissue, juice, or product to make the sample more uniform. Researchers then extract selected compounds with a suitable solvent before applying an analytical technique such as high-performance liquid chromatography, mass spectrometry, or spectrophotometry. The resulting measurements can be organized into profiles of nutrients, pigments, phenolics, sugars, acids, or other constituents.
The approach is useful when chemical measurements are needed to compare blueberry materials or verify product characteristics. Profiles of pigments, phenolics, sugars, acids, and other constituents can distinguish differences among cultivars and reveal changes associated with maturity or processing. These comparisons support quality control, authenticity assessment, and evaluation of blueberry-based products during development.
Chemical characterization provides measurable links between molecular composition and observed properties such as color and flavor. Researchers can use these data to study anthocyanin and phenolic patterns, examine maturity-related changes, or assess processing effects. The same information supports nutritional research and helps guide development of blueberry-based products by showing how composition varies across samples and treatments.
