Embryo–Endosperm Interactions [PDF]

Annual Review of Plant Biology, 2022
In angiosperms, double fertilization triggers the concomitant development of two closely juxtaposed tissues, the embryo and the endosperm. Successful seed development and germination require constant interactions between these tissues, which occur across their common interface. The embryo–endosperm interface is a complex and poorly understood compound

Maize endosperm development [PDF]

Journal of Integrative Plant Biology, 2021
AbstractRecent breakthroughs in transcriptome analysis and gene characterization have provided valuable resources and information about the maize endosperm developmental program. The high temporal‐resolution transcriptome analysis has yielded unprecedented access to information about the genetic control of seed development.

Cell Structure and Dynamics of Galactomannan Secretion in Caesalpinia pulcherrima (Leguminosae) Endosperm [PDF]

Plants
Galactomannans are a typical reserve polysaccharide in the endosperm of leguminous seeds; they turn the endosperm hard when dry and gelatinous and swollen when hydrated.

Loss of function of chromatin remodeler OsCLSY4 leads to RdDM-mediated mis-expression of endosperm-specific genes affecting grain qualities. [PDF]

PLoS Genetics
In plants, RNA-directed DNA methylation (RdDM) sequence-specifically targets transposable elements (TEs) and repeats, often in a tissue-specific manner.

Effect of Doum (Hyphaene thebaica) mesocarp and endosperm extracts on Triton X-100 induced hyperlipidemic rat: mitigative cardiovascular and renal dysfunction risks [PDF]

Frontiers in Nutrition
IntroductionHyperlipidemia increases the risk of cardiovascular (CVD) progression and renal dysfunction.ObjectivesThis study aimed to identify, for the first time, the protective effects of both the Hyphaene thebaica (Doum) edible mesocarp (DM) and ...

The 5-methylcytosine DNA glycosylase ROS1 prevents paternal genome hypermethylation in Arabidopsis endosperm [PDF]

Genome Biology
Background DNA methylation patterning is a consequence of opposing activities of DNA methyltransferases and DNA demethylases. In many plant and animal species, reproduction is a period of significant epigenome lability.

Integration of embryo–endosperm interaction into a holistic and dynamic picture of seed development using a rice mutant with notched-belly kernels

Crop Journal, 2022
Interaction between the embryo and endosperm affects seed development, an essential process in yield formation in crops such as rice. Signals that mediate communication between embryo and endosperm are largely unknown.

Endosperm–Embryo Communications: Recent Advances and Perspectives

Plants, 2021
Seed maturation depends on well-coordinated communications between the processes of endosperm and embryo development. The endosperm is considered to be destined to support embryo development and the timing of endosperm cellularization is critical for ...

Dynamic Transcriptome-Based Weighted Gene Co-expression Network Analysis Reveals Key Modules and Hub Genes Associated With the Structure and Nutrient Formation of Endosperm for Wax Corn

Frontiers in Plant Science, 2022
The endosperm of corn kernel consists of two components, a horny endosperm, and a floury endosperm. In the experiment, a kind of floury endosperm corn was identified.

Metabolic Disturbance Induced by the Embryo Contributes to the Formation of Chalky Endosperm of a Notched-Belly Rice Mutant

Frontiers in Plant Science, 2022
Grain chalkiness is a key quality trait of the rice grain, whereas its underlying mechanism is still not thoroughly understood because of the complex genetic and environmental interactions.
