Cold Spring Harb Perspect Biol 1:a001545. More intriguingly, RNA processing has been shown to be crucial for cell fate determination of the embryo sac. Auxin wird in den Zellen nicht direkt, sondern zumeist durch Auxin-induzierte Reportergenexpression nachgewiesen. 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. During the last two decades many players that regulate stem cell maintenance have been identified. However, embryos can also be formed from other cell types in many plant species. Die Aktivierung des embryonalen YODA-Signalwegs durch SSP führt zur Streckung und asymmetrischen Teilung der Zygote. Dadurch wird der Auxin-Transport nach unten gerichtet und es kommt zur Akkumulation von Auxin am basalen Ende des Embryos, wo das Wurzelmeristem entsteht. This facilitates the identification of founder cells for the primary root. On the other hand, lots of genes are used for massive reserves synthesis and accumulation before desiccating to form a seed [11] . Arabidopsis embryogenesis begins with fertilisation of the egg cell by one of the two sperm cells that are delivered by the pollen tube (Dumas and Rogowsky, 2008). Development of plant vascular tissues involves tissue identity specification, growth, pattern formation and cell type differentiation. Thus, a key question is how embryo identity in plants is controlled, and how this process is modified during nonzygotic embryogenesis. 3C) benötigt [7].
