PICKLE acts throughout the plant to repress expression of embryonic traits and may play a role in gibberellin-dependent responses.

A seed marks the transition between two developmental states; a plant is an embryo during seed formation, whereas it is a seedling after emergence from the seed. Two factors have been identified in Arabidopsis that play a role in establishment of repression of the embryonic state: PKL (PICKLE), which codes for a putative CHD3 chromatin remodeling factor, and gibberellin (GA), a plant growth reg...

germ cell-less Acts to Repress Transcription during the Establishment of the Drosophila Germ Cell Lineage

Previously, it has been shown that, during early Drosophila and C. elegans development, the germ cell precursors undergo a period of transcriptional quiescence. Here, we report that Germ cell-less (GCL), a germ plasm component necessary for the proper formation of "pole cells," the germ cell precursors in Drosophila, is required for the establishment of this transcriptional quiescence. While co...

Trim71 cooperates with microRNAs to repress Cdkn1a expression and promote embryonic stem cell proliferation

Pluripotent embryonic stem cells have a shortened cell cycle that enables their rapid proliferation. The embryonic stem cell-specific miR-290 and miR-302 microRNA families promote proliferation whereas let-7 microRNAs inhibit self-renewal, and promote cell differentiation. Lin28 suppresses let-7 expression in embryonic stem cells. Here to gain further insight into mechanisms controlling embryon...

ABI5 acts downstream of ABI3 to execute an ABA-dependent growth arrest during germination.

The development of a germinating embryo into an autotrophic seedling is arrested under conditions of water deficit. This ABA-mediated developmental checkpoint requires the bZIP transcription factor ABI5. Here, we used abi3-1, which is also unable to execute this checkpoint, to investigate the relative role of ABI3 and ABI5 in this process. In wild-type Arabidopsis plants, ABI3 expression and ac...

Use Distinct Pathways to Repress Telomerase Expression

Background: Inactivation of p53 and reactivation of telomerase expression are two of the most common events in human cancer. Results: Here we report the mechanisms used by p53, p63, and p73 to suppress telomerase expression. Conclusion: p53, p63, and p73 suppress telomerase expression through distinct pathways that involve E2F, E-box, c-Myc, and NF-YB. Significance: This study provides new insi...
