What attributes make Arabidopsis a suitable model plant for molecular genetic research?

Text Solution

Verified by Experts

Arabidopsis thaliana - Thale cress, Mouse ear cress
(i) It is a model plant for the study of genetic and molecular aspects of plant development.
(ii) It belongs to mustard family and it is the first flowering plant, where its entire genome is sequenced.
(iii) The two regions of the nucleolar organiser ribosomal DNA which codes for the ribosomal RNA are present at the extremity of chromosomes 2 and 4.
(iv) It is diploid plant having small genome with 2n = 10 chromosomes. Several generations can be produced in one year. So it facilitates rapid genetic analysis. The genome has low repetitive DNA, over 60% of the nuclear DNA have protein coding functions.
(v) The plant is small, self fertilizes, annual long-day plant with short-life cycle. Large numbers of seeds are produced and they are easy to be grown in laboratory. It is easy to induce mutations. It has many genomic resources and the transformation can be done easily.
(vi) In 1982, Arabidopsis has successfully completed its life cycle in microgravity i.e. space. This shows that Human Space Missions with plant companions may be possible.
