Imprinting is a phenomenon in plant and mammal reproduction. DNA methylation plays an important role in mechanisms of imprinting. Isolating endosperm and determining methylation status of imprinted genes in Arabidopsis can be difficult. In this protocol, we describe how to isolate endosperm and determine methylation by bisulfite sequencing.

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.

This protocol describes the preparation of intact samples of the endosperm cell layer in Arabidopsis thaliana seeds. The method requires only common laboratory equipment, such as an injection needle and precision forceps, and enables high-resolution fluorescent live-cell imaging of endosperm cells in both developing and mature seeds.

Here we present a protocol for laser-assisted microdissection of specific plant cell types for transcriptional profiling. While the protocol is suitable for different species and cell types, the focus is on highly inaccessible cells of the female germline important for sexual and apomictic reproduction in the crucifer genus Boechera.

Seed Structure and Early Development of the Sporophyte
0 Views •

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...
FAQs
Parent-of-origin effects mean that maternal and paternal genetic contributions can influence how the tissue develops, rather than acting as interchangeable inputs. In Endosperm Cells, this genomic relationship is a major research focus because it connects fertilization-derived tissue development with regulation of seed formation and helps explain differences in developmental outcomes.
The timing of nuclear division and cellularization provides distinct developmental stages for investigating how endosperm organization emerges. Nuclei may initially divide while remaining temporarily free, followed by formation of cellular structure. Comparing these stages helps developmental biologists relate cell-cycle behavior to later tissue specialization and the endosperm’s support of embryo growth.
Differentiation gives endosperm cells specialized roles beyond early tissue formation. As development proceeds, they accumulate starch, proteins, and oils, while also transferring nutrients to the embryo. These changes connect cellular specialization with practical developmental outcomes, including seed maturation and regulation of final seed size.
A focused study can track nuclear division, the onset of cellularization, differentiation, nutrient accumulation, and interactions with the developing embryo. These features provide a connected view of tissue progression rather than treating endosperm as a static structure. Following them helps relate cellular events to seed formation and maturation.
Because endosperm cells accumulate storage materials and support embryo growth, their development is relevant to seed quality and crop yield. Research can examine how tissue differentiation, nutrient transfer, and seed-size regulation relate to these outcomes. This developmental perspective also contributes to efforts addressing agricultural resilience.
Endosperm cells connect several central themes in developmental biology: cell division, genomic parent-of-origin effects, tissue specialization, and coordinated growth within a developing seed. Studying these relationships shows how a fertilization-derived tissue develops distinct functions while influencing embryo support, seed maturation, and the formation of the mature seed.
