Plant Cell 22:3249–3267. Bot Not 133:323–336, CAS  CAS  Here, we report that the closely related NF-YA3 and NF-YA8 play an important role in Arabidopsis embryogenesis. A., Moan E. I., Medford J. I., Barton M. K. (1996). Here, we show that the interleukin-1 receptor–associated kinase (IRAK)/Pelle-like kinase gene SHORT SUSPENSOR ( SSP ) regulates this pathway through a previously unknown parent-of-origin effect. 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. https://doi.org/10.1126/science.1167784, Belmonte MF et al (2013) Comprehensive developmental profiles of gene activity in regions and subregions of the Arabidopsis seed. Immediate online access to all issues from 2019. The resulting RNA-seq datasets identify distinct overlapping patterns of gene expression, as well as temporal shifts in gene activity across embryogenesis. Network analysis revealed stage-specific and multi-stage gene expression clusters and biological functions associated with key stages of embryo development.

Google Scholar, Yang H, Xiang D, Venglat S, Cao Y, Wang E, Selvaraj G, Datla R (2009) PolA2 is required for embryo development in Arabidopsis. Thus, a key question is how embryo identity in plants is controlled, and how this process is modified during nonzygotic embryogenesis. 3: Auxin-Transport und Auxin-Antwort in der frühen Embryogenese.

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 … Nambara E, Hayama R, Tsuchiya Y, Nishimura M, Kawaide H, et al. Wie bereits beschrieben, teilt sich die Zygote von Arabidopsis in zwei verschieden große Zellen, die auch verschiedene Gene exprimieren und verschiedene Zellschicksale annehmen [3]. The Arabidopsis (Arabidopsis thaliana) zygote divides to produce an embryonic lineage and an extra-embryonic suspensor. More intriguingly, RNA processing has been shown to be crucial for cell fate determination of the embryo sac. Metabonomics of Arabidopsis embryo development.
