Genome-Wide Comparative Analysis of Flowering-Related Genes in Arabidopsis, Wheat, and Barley

Table 3

Structural characteristics of flowering-related genes in Arabidopsis thaliana (AT), Triticum aestivum (TA), and Hordeum vulgare (HV).

	AT ()		TA ()		HV ()
	Mean	Range	Mean	Range	Mean	Range
Transcripts per gene	1.4	1–5	1.0	1-1	2.8	1–27
Gene length (bp)	3161	182–16871	3815	240–20952	4328	404–15512
Exons per gene	6.5	1–48	5.7	1–42	4.5	1–20
Exon size (bp)	466	79–4165	565	42–5550	878	87–5211
Intron size (bp)	468	78–2316	924	58–7291	856	44–5912
Protein length (aa)	529	77–3529	444	52–3250	500	50–2056

The numbers of flowering genes used for the summary statistics are shown in parentheses. Single-exon genes (no introns) were excluded for intron size calculation. bp, base pair; aa, amino acid.
