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. Thus, we conclude that CTPS2 is essential for CTP supply in the developing embryo and a knockout of CTPS2 is embryo lethal. The embryos of seed plants develop with an apical shoot pole and a basal root pole. https://doi.org/10.1104/pp.107.115246.

A contribution to the special issue ‘Cellular Omics Methods in Plant Reproduction Research’. The Arabidopsis LEAFY COTYLEDON1 (LEC1) gene is required for the specification of cotyledon identity and the completion of embryo maturation. The results of this study using two mutant alleles of ATML1 and four mutant alleles of PDF2 reveal that at least one copy of the wild-type allele of either ATML1 or PDF2 is essential for embryo development in Arabidopsis. 3: Auxin-Transport und Auxin-Antwort in der frühen Embryogenese.

Embryo without SED1 developed slower compared to normal one and could be recognized at early globular stage by its white appearance. Somatic and haploid embryo development in Arabidopsis. 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. The YODA ( YDA ) mitogen-activated protein kinase pathway promotes elongation of the Arabidopsis zygote and development of its basal daughter cell into the extra-embryonic suspensor. (C) Globularstadium; (D) Herzstadium; (E) Keimling. CLE8 is the only Arabidopsis CLE gene that is expressed exclusively in seed-bearing siliques (Sharma et al., 2003), and thus we hypothesized that CLE8 might play a specific role in seed development.

Diese nicht-autonome Wirkung der Auxin-Antwort wird offenbar durch zwei nachgeschaltete Vorgänge vermittelt: In Abhängigkeit vom Auxinpegel steuert MP die Expression von PIN1 und damit indirekt den Transport von Auxin zur obersten Suspensorzelle.
