What is special about Arabidopsis thaliana?
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.
Is Arabidopsis thaliana easy to grow?
A. thaliana is easy to look after compared with animal model organisms. It grows quickly, produces many very small seeds, has a small genome ~114.5 Mb and is genetically well characterised due to the volume of work being focused on this plant.
Why is Arabidopsis used?
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.
What is the life cycle of Arabidopsis thaliana?
1) It has a short life cycle- Arabidopsis completes its life cycle in 8-12 weeks from germination to harvesting. 2) It easily grows in a restricted space and is very easy to maintain in an indoor growth chamber. 3) It produces many seeds.
Why Arabidopsis thaliana is used as a model?
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.
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.
Is Arabidopsis thaliana invasive?
Arabidopsis thaliana (L.) Heynh. Mouse-ear thale-cress is native to Europe, Asia and North Africa, and invasive over much of North America.
How do I get rid of mouse-ear cress?
The best way to kill chickweed is by pulling as much of it out of the ground as possible by hand. Both species have shallow roots and can be easily removed by hoeing or hand pulling. However, since new plants can develop from mouse-ear rootstock, removing the entire plant is how to kill chickweed.
What is the activity of mir172 in Arabidopsis?
We functionally analyzed the activity of all 5 Arabidopsis thaliana MIR172 genes, which encode miR172 and promote the floral transition by inhibiting the accumulation of APETALA2 (AP2) and APETALA2-LIKE (AP2-LIKE) transcription factors (TFs).
Which is the target of mir172 in A thaliana?
The targets of miR172 are the mRNAs of the APETALA2-LIKE (AP2-LIKE) TF family, and this interaction is conserved across spermatophytes [ 17, 18 ]. In A. thaliana, there are 6 members of the AP2-LIKE TF family APETALA2 (AP2), TARGET OF EAT1 (TOE1), TOE2, TOE3, SCHNARCHZAPFEN (SNZ), and SCHLAFMÜTZE (SMZ).
What are the targets of the mir172 gene?
Here, we follow both strategies to inactivate all 5 members of the MIR172 gene family in Arabidopsis thaliana. The targets of miR172 are the mRNAs of the APETALA2-LIKE (AP2-LIKE) TF family, and this interaction is conserved across spermatophytes [ 17, 18 ].
What is the activity of mir172 at the shoot apex?
Through genome editing and detailed confocal microscopy, we show that the activity of miR172 at the shoot apex is encoded by 3 MIR172 genes, is critical for floral transition of the shoot meristem under noninductive photoperiods, and reduces accumulation of AP2 and TARGET OF EAT2 (TOE2), an AP2-LIKE TF, at the shoot meristem.
