What is GLABRA 2?
Description. Glabra 2, a homeodomain protein affects epidermal cell identity including trichomes, root hairs, and seed coat. It also down-regulates seed oil content. Expressed in atrichoblasts and required to suppress root hair development. Also expressed abundantly during early seed development.
Why is it important to study GL2?
More and more evidence suggest that GL2 plays a central role in the regulation of epidermal cell fate determination and anthocyanin biosynthesis.
What describes transcription factors?
Transcription factors are proteins involved in the process of converting, or transcribing, DNA into RNA. Transcription factors include a wide number of proteins, excluding RNA polymerase, that initiate and regulate the transcription of genes.
What is a primary function of transcription factors?
What is a primary function of transcription factors? They control gene expression.
What is TATA box in transcription?
A TATA box is a DNA sequence that indicates where a genetic sequence can be read and decoded. It is a type of promoter sequence, which specifies to other molecules where transcription begins. Transcription is a process that produces an RNA molecule from a DNA sequence.
Why is p53 called the guardian of the genome?
By stopping cells with mutated or damaged DNA from dividing, p53 helps prevent the development of tumors. Because p53 is essential for regulating DNA repair and cell division, it has been nicknamed the “guardian of the genome.”
What type of protein is p53?
The p53 gene is a type of tumor suppressor gene. Also called TP53 gene and tumor protein p53 gene.
Why TATA box is important?
The TATA box is essential for transcription and binds either TBP or the Acanthamoeba version of TFIID (32). The start site region is not essential, but serves to constrain the positioning of RNA polymerase II (24).
Do humans have TATA box?
About 24% of human genes have a TATA-like element and their promoters are generally AT-rich; however, only ∼10% of these TATA-containing promoters have the canonical TATA box (TATAWAWR).
What is the difference between Arabidopsis lyrata and Arabidopsis glabra?
petals mostly 2-3.5 mm long and mature fruits mostly 10-15 mm long (vs. A. lyrata, with petals mostly 6-8 mm long and mature fruits mostly 20-40 mm long). A. lyrata L. var. glabra (DC.) M. Hopkins Our subspecies is Arabidopsis lyrata (L.) O’Kane & Al-Shehbaz ssp. lyrata.
What is the function of glabra 2?
Glabra 2, a homeodomain protein affects epidermal cell identity including trichomes, root hairs, and seed coat. It also down-regulates seed oil content. Expressed in atrichoblasts and required to suppress root hair development.
What plants grow with Arabidopsis lyrata?
The species that grow with Arabidopsis lyrata are Senecio obovatus, Viburnum rafinesquianum, Micranthes virginiensis, Asplenium platyneuron, Campanula rotundifolia, Carya species, Woodsia ilvensis, and Aquilegia canadensis. Arabidopsis lyrata is eaten by many herbivores such as the cabbage white butterfly, Pieris brassicae.
Why does A thaliana have smaller introns than Arabidopsis lyrata?
A. thaliana has smaller introns than Arabidopsis lyrata because of different indel dynamics in both species ( Wright et al., 2002 ).
