Abstract

Seed development in this paper has been classified into the three landmark stages of cell division, organ initiation and maturation, based on morphological changes, and the available literature. The entire process proceeds at the behest of an interplay of various specific and general transcription factors (TFs). Monocots and dicots utilize overlapping, as well as distinct, TF networks during the process of seed development. The known TFs in rice and Arabidopsis have been chronologically categorized into the three stages. The main regulators of seed development contain B3 or HAP3 domains. These interact with bZIP and AP2 TFs. Other TFs that play an indispensable role during the process contain homeobox‐, NAC‐, MYB‐, or ARF‐domains. This paper is a comprehensive analysis of the TFs essential for seed development and their interactions. An understanding of this interplay will not only help unravel an integrated developmental process, but will also pave the way for biotechnological applications.

In mouse development, transcription is first detected in late 1-cell embryos, but translation of newly synthesized transcripts does not begin until the 2-cell stage. Thus, the onset of zygotic gene expression (ZGE) is regulated at the level of both transcription and translation. Chromatin-mediated r

Subnuclear compartmentation is postulated to play an important role in many aspects of nuclear metabolism. To directly test an application of this model to transcription factor function, we examined the subnuclear partitioning behavior of Pit-1, a tissue-specific, POU-class transactivator. Biochemic
