Significant advances in understanding plant growth and development have been made by focusing on the molecular genetics of this simple angiosperm. More than 2,500 laboratories and 8,000 scientists worldwide are using a new generation of tools to probe this plant's genome, revealing processes common to all plants. In this study, we identified variation in ovule number per flower in a screen of 189 Arabidopsis accessions and conducted a Genome Wide Association Study (GWAS) to identify loci associated with the ovule number trait. In an application with 71 female and 71 male human individuals, findGSE delivered an average of 3039 Mb as haploid human GS, while female genomes were on average 41 Mb larger than male genomes, in astonishing agreement with size difference of the X and Y chromosomes.

The Arabidopsis Genome Initiative (AGI) began in 1996 . In fact, the size of the A. thaliana genome has been recently estimated as approximately 157 Mbp (around 20% larger than the estimate published with the genome sequence), and the additional size appears to be due to (unsequenced) heterochromatic repetitive DNA in the centromeres, telomeres and nucleolar-organizing regions . The most recently revised genome size for A. thaliana is reported to be 1C = 157 Mega basepairs (Mb) (Bennett et al., 2003). Arabidopsis thaliana was adopted as a model plant due to its short generation time, small size, ease of growth and prolific seed production through self-pollination. Tabata S, et al. Nature 408, 796-815. Since the completion of the genome sequence project four years ago (The Arabidopsis Genome Initiative, 2000), and many updates of the annotation later, biologists and bioinformaticians still devote much of their time to improve and decode the content of the five Arabidopsis chromosomes.
