Plum blossoms symbolize the noble mind, grace, perseverance, and perfection.

As the flower symbolizes, the plum blossom endures the winter cold and blooms.

Arabidopsis thalina pollen grains of the qrt1 mutant

Mutation of QUARTET1 (QRT1) gene results in the four-pollen products of male meiosis remaining attached to one another, which allows classical tetrad analysis. 

Arabidopsis as a model plant

-please check the underlined link

Here is the Life cycle of Arabidopsis thaliana.

Easy to grow and growing fast

6-7 weeks to see flowers

8-9 weeks to collect sufficient pollen grains

12 weeks to harvest whole seeds from individual plants

Perfect genome sequence

Easy genetic engineering using Agrobacterium-mediated transformation

Powerful genetic screening

Genomic/Epigenomic data are available

Seed or pollen Fluorescence-Tagged Lines (FTLs) are available

FTLs enable to measure crossover frequency and interference
