“…A number of markers were identified that are closely linked to fgr (Ahn et al, 1992;Causse et al, 1994;Chen et al, 1997;Cho et al, 1998;Jin et al, 2003). Two restriction fragment length polymorphism markers, RG1 and RG28, were identified that flank fgr, with the estimates of genetic distances ranging from 10 centimorgan (cM) (Causse et al, 1994) to 12 cM (Lorieux et al, 1996) to 25.5 cM (Cho et al, 1998). After genetic mapping and sequence analysis of 17 genes in the fgr region, Bradbury et al (2005) suggested that a gene encoding putative betaine aldehyde dehydrogenase (BADH2) is most likely to be the fgr gene, due to its sequence divergence between fragrant and nonfragrant rice varieties.…”

In rice (Oryza sativa), the presence of a dominant Badh2 allele encoding betaine aldehyde dehydrogenase (BADH2) inhibits the synthesis of 2-acetyl-1-pyrroline (2AP), a potent flavor component in rice fragrance. By contrast, its two recessive alleles, badh2-E2 and badh2-E7, induce 2AP formation. Badh2 was found to be transcribed in all tissues tested except for roots, and the transcript was detected at higher abundance in young, healthy leaves than in other tissues. Multiple Badh2 transcript lengths were detected, and the complete, full-length Badh2 transcript was much less abundant than partial Badh2 transcripts. 2AP levels were significantly reduced in cauliflower mosaic virus 35S-driven transgenic lines expressing the complete, but not the partial, Badh2 coding sequences. In accordance, the intact, full-length BADH2 protein (503 residues) appeared exclusively in nonfragrant transgenic lines and rice varieties. These results indicate that the full-length BADH2 protein encoded by Badh2 renders rice nonfragrant by inhibiting 2AP biosynthesis. The BADH2 enzyme was predicted to contain three domains: NAD binding, substrate binding, and oligomerization domains. BADH2 was distributed throughout the cytoplasm, where it is predicted to catalyze the oxidization of betaine aldehyde, 4-aminobutyraldehyde (ABald), and 3-aminopropionaldehyde. The presence of null badh2 alleles resulted in AB-ald accumulation and enhanced 2AP biosynthesis. In summary, these data support the hypothesis that BADH2 inhibits 2AP biosynthesis by exhausting AB-ald, a presumed 2AP precursor.

“…Inconsistencies in the genotype proportions can be due to genotyping errors, to fragments of the same size scored as a single marker whereas they are derived from distinct loci or to a selective advantage as suggested in plants [3,27] and fish [48]. Non-Mendelian segregating markers occur at various rates: for instance 15% in peach rootstocks [20], 27.4% in rice [4], 56% in the silkworm [41], and 64% in Brassica oleracea [43]. On average, in each family, only 13.6 ± 5.9% of the AFLP markers developed in the Japanese quail were distorted.…”

“…In many studies, markers such as RFLP (restriction fragment length polymorphism), CAPS (cleaved amplified polymorphic sequence), microsatellites or genes are used together with AFLP markers. They can provide clues about the chromosome assignment of linkage groups or links to existing maps [2,31], but they can also give a framework to which AFLP markers are added [4]. Here, the markers are presented in their most likely order.…”

AFLP linkage map of the Japanese quail Coturnix japonica

-The quail is a valuable farm and laboratory animal. Yet molecular information about this species remains scarce. We present here the first genetic linkage map of the Japanese quail. This comprehensive map is based solely on amplified fragment length polymorphism (AFLP) markers. These markers were developed and genotyped in an F2 progeny from a cross between two lines of quail differing in stress reactivity. A total of 432 polymorphic AFLP markers were detected with 24 TaqI/EcoRI primer combinations. On average, 18 markers were produced per primer combination. Two hundred and fifty eight of the polymorphic markers were assigned to 39 autosomal linkage groups plus the ZW sex chromosome linkage groups. The linkage groups range from 2 to 28 markers and from 0.0 to 195.5 cM. The AFLP map covers a total length of 1516 cM, with an average genetic distance between two consecutive markers of 7.6 cM. This AFLP map can be enriched with other marker types, especially mapped chicken genes that will enable to link the maps of both species and make use of the powerful comparative mapping approach. This AFLP map of the Japanese quail already provides an efficient tool for quantitative trait loci (QTL) mapping. Japanese quail / AFLP / genetic map / linkage groups / chromosomes

“…A universal core genetic map (UCGM) was constructed with different rice accessions to facilitate the comparison of low resolution genetic maps with evenly distributed markers in rice (Orjuela et al, 2009). An integrated map of AFLP, SSLP and RFLP was constructed (Cho et al, 1998) with a population derived from Milyang 23 and Gihobyeo in Korean Rice Genome Research Project (KRGRP). Another kind of marker, called as Amplified Fragment Length Polymorphism (AFLP) has been described (Vos et al, 1995) and it was utilized in the genetic map construction along with previously mapped RFLP markers in rice (Causse et al, 1994;Maheswaran et al, 1997).…”
