“…The first genetic linkage map for sunflower was actually developed for a wild hybrid species, H. anomalus (Rieseberg et al 1993), which is divergent chromosomally from the domesticated sunflower (Rieseberg et al 1995). However, shortly thereafter several restriction fragment length polymorphism maps were published for the domesticated sunflower (Berry et al 1995;Gentzbittel et al 1995Gentzbittel et al , 1999Jan et al 1998), establishing a standard nomenclature for sunflower linkage groups and providing framework markers for comparisons among maps (Gedil et al 2001). More recently, high-resolution linkage maps based on more than 1,000 simple sequence repeat (SSR) and other sequence-tagged-site markers have been developed for the cultivated sunflower Yu et al 2003) and several wild species Burke et al 2004;Lai et al 2005).…”

Identification and mapping of SNPs from ESTs in sunflower

et al. 2005

More than 67,000 expressed sequence tags (ESTs) have recently been generated for sunflower (Helianthus), including 44,000 from cultivated confectionery (RHA280) and oilseed (RHA801) lines of Helianthus annuus and 23,000 from droughtand salt-tolerant wild sunflowers, H. argophyllus and H. paradoxus, respectively. To create a transcript map for sunflower, we identified 605 ESTs that displayed small insertion-deletion polymorphism (SNP) variation in silico, had apparent tissuespecific expression patterns, and/or were ESTs with candidate functions in traits such as development, cell transport, metabolism, plant defense, and tolerance to abiotic stress. Primer pairs for 535 of the loci were designed from the ESTs and screened for polymorphism in recombinant inbred lines derived from a cross between the same cultivars (RHA280 × RHA801) employed for sequencing. In total, 273 of the loci amplified polymorphic products, of which 243 mapped to the 17 linkage groups previously identified for sunflower. Comparisons with previously mapped QTL revealed some cases where ESTs with putatively related functions mapped near QTLs identified in other crosses for salt tolerance and for domestication traits such as stem diameter, shattering, flowering time, and achene size.

“…Sunflower would benefit greatly from a systematic effort to map functionally important genes in order to search for associations between candidate genes and QTLs underlying agriculturally or evolutionarily important traits (e.g., Gentzbittel et al 1999;Slabaugh et al 2003;Lexer et al 2004). …”

“…So far, a number of genetic linkage maps of sunflower, varying in density and the used markers, were developed. The first genetic maps were based on RFLP (1,2,12,13,17) or RFLP and AFLP (9,27). The development of a large set of microsatellite markers (simple sequence repeats, SSRs) (9,35,36,40) (http:// compositdb.ucdavis.edu) allowed the construction of high density microsatellite maps (36,41,42).…”

“…Despite its economic value, the number of simply inherited genes identified in sunflower is relatively small (Miller, 1992), and there is no classical genetic map for this species. Several sunflower RFLP linkage maps were published recently (Berry et al, 1995;Gentzbittel et al, 1995Gentzbittel et al, , 1999Jan et al 1998), but unfortunately the relationship between these different maps is unknown, because the vast majority of the markers are not publicly available. The mapping of major gene loci, such as the Rf1 locus Berry et al, 1997;Jan et al, 1998), the downy mildew resistance gene cluster (Vear et al, 1997), Orobanche resistance (Lu et al, 2000) and the Hyp-1 locus (León et al, 1996), as well as protein markers, such as seed storage proteins (Serre et al, 2001) and isozymes, will provide landmarks allowing the alignment of some linkage groups.…”

Variability among inbred lines and RFLP mapping of sunflower isozymes

et al. 2002

Eight isozyme systems were used in this study: acid phosphatase (ACP), alcohol dehydrogenase (ADH), esterase (EST), glutamate dehydrogenase (GDH), malate dehydrogenase (MDH), phosphoglucoisomerase (PGI), 6-phosphogluconate dehydrogenase (PGD), and phosphoglucomutase (PGM). The polymorphism of these enzyme systems was studied in 25 elite inbred lines. A total of 19 loci were identified, but only eight of them were polymorphic in the germplasm tested. The polymorphic index for the eight informative markers ranged from 0.08 to 0.57, with a mean value of 0.36. Five isozyme loci were mapped in F 2:3 populations with existing RFLP data. Est-1, Gdh-2 and Pgi-2 were mapped to linkage groups 3, 14 and 9, respectively. As in previous reports, an ACP locus and a PGD locus were found to be linked, both located in linkage group 2 of the public sunflower map.
