What is Arabidopsis thaliana used for?
Arabidopsis thaliana is a model organism used to determine specific defense mechanisms of plant-pathogen resistance. These plants have special receptors on their cell surfaces that allow for detection of pathogens and initiate mechanisms to inhibit pathogen growth.
Why is Arabidopsis thaliana important for research?
Arabidopsis thaliana, a small annual weed belonging to the mustard family, has become a widely used model in plant genetic research. The importance of this plant to biotechnology is that genes isolated from Arabidopsis can be used to find their homologs in crop plants.
Which one is Arabidopsis DB?
The Arabidopsis Information Resource (TAIR) is a community resource and online model organism database of genetic and molecular biology data for the model plant Arabidopsis thaliana, commonly known as mouse-ear cress.
How many transcription factors are in Arabidopsis?
1500 transcription factors
Arabidopsis dedicates over 5% of its genome to code for more than 1500 transcription factors, about 45% of which are from families specific to plants.
Can you eat Arabidopsis thaliana?
A. Like many species in the Brassicaceae, A. thaliana are edible by humans, and can be used similarly to other mustard greens, in salads or sautéed, but its use as an edible spring green is not widely noted.
What is the meaning of Arabidopsis?
: a small genus of annual or biennial herbs (family Brassicaceae) of north temperate regions with basal rosettes of petioled leaves, cauline leaves short-petioled or clasping, and flowers having white, purplish, or sometimes yellow petals — see mouse-ear cress.
Why Arabidopsis is world best studied plant?
What’s more, Arabidopsis is easy and inexpensive to grow, and produces many seeds; this allows extensive genetic experiments, often involving tens of thousands of plants. Also, Arabidopsis has a comparatively small genome, thereby simplifying and facilitating genetic analysis.
Why Arabidopsis is used as model organism?
Arabidopsis was originally adopted as a model organism because of its usefulness for genetic experiments. Important features included a short generation time, small size that limited the requirement for growth facilities, and prolific seed production through self-pollination.
What is TIGR database?
Provides a collection of curated databases containing DNA and protein sequence, gene expression, cellular role, protein family, and taxonomic data for microbes, plants and humans. The CMR (Comprehensive Microbial Resource) contains analysis on completed microbial genome sequencing.
What is TAIR database?
The Arabidopsis Information Resource (TAIR) maintains a database of genetic and molecular biology data for the model higher plant Arabidopsis thaliana . TAIR also provides extensive linkouts from our data pages to other Arabidopsis resources. TAIR is located at Phoenix Bioinformatics and funded by subscriptions.
What are TGA transcription factors?
TGA transcription factors (TFs) are the members of bZIP family which is highly conserved in plants, animals, and micro-organisms. The Arabidopsis TGAs has 10 members and play crucial roles in disease resistance, stress mitigation, and flower development.
What is NAC transcription factor?
The NAC (NAM, ATAF and CUC) family is one of the largest plant-specific transcription factor (TF) families. They affect plant immunity through their regulatory impact on signaling of plant hormones, which in turn are key players in plant immune responses.
How many SPL genes are there in Arabidopsis?
Arabidopsis has 16 SBP-LIKE ( SPL) genes, 10 of which are targeted by miR156 [ 3, 5, 11 – 14 ]. These genes can be grouped into 5 clades based on the amino acid sequence of their conserved DNA binding domain— SPL3/SPL4/SPL5, SPL9/SPL15, SPL2/SPL10/SPL11, SPL6 and SPL13A/B [ 12, 13, 15 ].
What are the functions of SPL in Arabidopsis thaliana?
Developmental Functions of miR156-Regulated SQUAMOSA PROMOTER BINDING PROTEIN-LIKE (SPL) Genes in Arabidopsis thaliana Correct developmental timing is essential for plant fitness and reproductive success.
How are SPL genes regulated by MIR156 in plants?
The phenotype of plants over-expressing miR156 demonstrates that these genes control many aspects of plant development and physiology, but the functions of individual miR156-regulated SPL genes, and how their expression is regulated by miR156, are largely unknown.
What is the function of miR156 in Arabidopsis?
These results provide a framework for future studies of this multifunctional family of transcription factors, and offer new insights into the role of miR156 in Arabidopsis development. In Arabidopsis, miR156 acts by repressing the expression of 10 SQUAMOSA PROMOTOR BINDING PROTEIN-LIKE ( SPL) genes.
