– Perhaps Arabidopsis thaliana, the botanical wonder. The only species other than man whose genome is thoroughly analysed.


Arabidopsis thaliana


– Any particular reasons Sir  for why this plant genome is analysed thoroughly ?


These might be the probable reasons
    1. Annual plant; so one can observe all the phenological stages within a years span. Acutally Arabidopsis can complete its entire life cycle in six weeks. The central stem that produces flowers grows after about three weeks,  and the flowers naturally self-pollinate. In the lab Arabidopsis may be grown in petri plates or pots, under fluorescent lights or in a greenhouse–which makes it easy to study the entire plant in a short span as well
    2. Earlier it was thought to have the smallest genome among the flowering plants – this might have led the scientist to take it up for research (now the plant to have the smallest genome is the Genus Genlisea<
http://en.wikipedia.org/wiki/Genlisea>, Lamiales with 63.4 Mbp vs 157 of Arabidopsis thaliana)
   3. Only 5 pair of Chromosomes, convenience in studying them
   4. The small size of the plant is convenient for cultivation in a small space and it produces many seeds.
   5. Further, the selfing nature of this plant assists genetic experiments.
   6. Finally, the plant is well suited for light microscopy analysis as the young seedlings on the whole, and their roots in particular, are relatively translucent.
   7. This, together with their small size, facilitates live cell imaging using both fluorescence and laser scanning microscopy. 
   8. By wet mounting seedlings in water or in culture media, plants may be imaged un-invasively, obviating the need for fixation and sectioning and allowing time-lapse measurements.
 
    Each of the above criteria leads to Arabidopsis thaliana being valued as a genetic model organism.
    These are some of the reasons which (might have) led to selection of the plant for the Genome Research Project.


These pages from my book should answer your question.

ID this plant,its from Brassicaceae,Lahore Pakistan : 6 posts by 3 authors. Attachments (1)


is it Arobidospsi sp??? can any one ID it plzzzz


Thank you for introducing to a new species from your country.
I agree with your ID, it does look like Arabidopsis thaliana (L.) Heynh.
Please wait for our experts.
