Abstract

We developed 708 gene-based markers for citrus genome analysis. Sequence-tagged site (STS) primers were designed that were located in conserved exon regions and whose PCR products spanned genomic introns. Of these, 79.7 % comprised cleaved amplified polymorphic sequence markers. The gene-based markers and their annotation and position on Clementine scaffolds ver. 1.0 permitted comparison of the genetic map and the Clementine genome sequence. The 708 gene-based markers were used to construct a genetic map using the 87 progenies (AG population) from the cross between ‘Okitsu 46 gou’ (‘Sweet Spring’ (‘Ueda unshiu’ (Citrus unshiu) × Hassaku (Citrus hassaku Hort. ex Tanaka)) × ‘Trovita’ orange) × ‘Kankitsu Chukanbohon Nou 5 gou’ (‘Lee’ (Citrus clementina × tangelo) × Citrus kinokuni). The markers were integrated using common STSs on different phase maps in cross-pollination mode. The integrated map (AGI map) comprised 706 loci, including two morphological traits, and spanned 990.9 centimorgans (cM) with an average marker distance of 1.40 cM. These markers formed nine linkage groups (LGs) (corresponding to citrus physical chromosomes): LG-01 to LG-09 corresponded to Scaffold_01, Scaffold_07, Scaffold_09, Scaffold_06, Scaffold_03, Scaffold_02, Scaffold_04, Scaffold_08, and Scaffold_05, respectively. LG-08 and LG-09 contained morphological traits controlling embryo color and seedlessness. Eighty-eight loci comprised three or more alleles on the AGI map; 36.4 % of them were related to transcription factors and DNA-binding proteins. The 708 gene-based markers and the AGI map are valuable for integrating various citrus genetic maps, alignment of genomic sequences, chromosome assignment, and understanding the diversity of citrus germplasms.
