Disruption of nuclear genes encoding chloroplast and mitochondrial proteins can also result in a variety of defects later in development. Plant Physiol. The development of Arabidopsis embryos can be divided into globular-shaped, heart-shaped, torpedo-shaped, and cotyledon-shaped stages sequentially. Giovanna Sessa. investigated,theArabidopsis zygotedividesasymmetricallytogive rise to two daughter cells of different developmental perspectives (Figures 2A,B). Arabidopsis; embryo; nucleotide synthesis; plastid; pentose phosphate pathway; Large numbers of genes (called EMB genes) are essential for embryo development in Arabidopsis: emb mutants undergo developmental arrest before maturity, leading to seed abortion, nonviable seeds, or nonviable seedlings (1 ⇓ ⇓ ⇓ ⇓ –6).Many EMB genes encode proteins directly involved in fundamental … Cell 145:707–719. https://doi.org/10.7554/eLife.03198, Article  2, 3; [10]). An alternative explanation is that there is a regulatory role of the nucleolar function for embryo sac development in Arabidopsis, for example, to coordinate transcriptional and translational activities during the rapid growth of the embryo sac. Embryo without SED1 developed slower compared to normal one and could be recognized at early globular stage by its white appearance. In Arabidopsis and maize correct seed development requires a coordinated crosstalk between the seed tissues (mainly embryo and endosperm). In this study, we investigated the function of two types of proton pumps in Arabidopsis embryo development and pattern formation. Embryo sac development in Arabidopsis thaliana.

The expression pattern of the transcription factor KAN2 (green) defines the abaxial/peripheral domain of the embryo and shoot. Der Transkriptionsfaktor TMO7 bewegt sich aus dem unteren Bereich des Proembryos in die benachbarte Suspensorzelle und beeinflusst deren Schicksal dahingehend, dass embryonales Wurzelmeristem angelegt wird [9]. Development of plant vascular tissues involves tissue identity specification, growth, pattern formation and cell type differentiation. While disruption of either V‐PPase or V‐ATPase had no obvious effect on plant embryo development, knocking out both resulted in severe defects in embryo pattern formation from the early stage. 1: Zellteilungsmuster und Zellschicksale in der frühen Embryogenese. Dabei fördert YODA-Aktivität die Differenzierung zu Suspensorzellen. During the last two decades many players that regulate stem cell maintenance have been identified.
