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.
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
