We have succeeded in establishing a method for RNA isolation from plant seeds containing large amounts of oils, proteins, and polyphenols, which have inhibitory effects on high-purity RNA isolation. Our method is suitable for monitoring the expression of genes with low level transcripts in seeds.

Seed Structure and Early Development of the Sporophyte

2020
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo. The embryo contains a double set of chromosomes, one set from each parent. Fertilization of the haploid egg by the haploid sperm gives rise to the zygote, which develops into the embryo. The endosperm is a...

A Seed Coat Bedding Assay to Genetically Explore In Vitro How the Endosperm Controls Seed Germination in Arabidopsis thaliana

We present the procedure to assemble a seed coat bedding assay (SCBA) from Arabidopsis thaliana seeds. The SCBA was shown to be a powerful tool to explore genetically and in vitro how the endosperm controls seed germination in dormant seeds and in response to light cues. The SCBA is in principle applicable under any situation where the endosperm is suspected to influence embryonic growth.

Introduction to Seed Plants

Most plants are seed plants—characterized by seeds, pollen, and reduced gametophytes. Seed plants include gymnosperms and angiosperms. Gymnosperms—cycads, ginkgo biloba, gnetophytes, and conifers—typically form cones. The pollen cones contain male gametophytes. The ovulate cones contain female gametophytes and form exposed seeds when fertilized. Angiosperms, the most diverse and ubiquitous group of land plants, form flowers, and fruit. Like the cones of gymnosperms, the flowers and fruit of...
FAQs
Chromatographic separation helps distinguish individual constituents in a complex seed extract before detection measures their chemical signals. Mass spectrometric or other spectroscopic detection then supports identification and quantification of compounds such as atropine, scopolamine, and hyoscyamine. Using both stages provides more informative results than relying on an undifferentiated extract signal alone.
Calibration connects the measured analytical response with the amount of a target compound present in the sample. In Datura Seeds Analysis, this supports quantitative estimates for atropine, scopolamine, hyoscyamine, and other constituents. Reliable calibration is therefore part of determining whether reported alkaloid concentrations accurately represent the analyzed botanical material.
Processing and storage may affect the chemical composition observed in Datura seeds, so results should be interpreted in relation to the material’s history when that information is available. Comparing alkaloid profiles across differently handled samples can help investigators study these effects and distinguish compositional differences from analytical variation.
Sample preparation determines how seed material is made ready for chemical measurement. Homogenization prepares the material for extraction, while transferring target compounds into a suitable solvent makes them available for chromatographic and spectroscopic analysis. Careful preparation helps maintain a consistent path from the original seeds to the reported chemical profile.
A typical workflow begins by homogenizing the seed material, followed by extracting target compounds into a suitable solvent. The extract is then subjected to chromatographic separation and mass spectrometric or other spectroscopic detection. Calibration and contamination control accompany these stages, supporting identification and measurement of the resulting alkaloid constituents.
The analysis is useful when investigators need chemical evidence about Datura seed material or its toxic alkaloids. In forensic and toxicological research, results can support poisoning investigations, assess the composition of botanical materials, and document alkaloid profiles. These applications depend on controlled preparation, appropriate calibration, and protection against contamination.
An alkaloid profile shows which measured constituents are present and supports comparison of their amounts within the analyzed material. For Datura seeds, attention may focus on atropine, scopolamine, and hyoscyamine. Such profiles can assist botanical-material assessment, poisoning investigations, and studies examining how processing or storage relates to chemical composition.
