“…L34844 and L34842; Cope and Pratt 1992) was mapped on linkage group O using a SNP marker at the same position as GmPhyA1 (Choi et al 2007). GmPhyA2, the gene responsible for the E4 locus, was mapped on LG I (Liu et al 2008). Therefore, together with GmPhyA3, at least three PhyA genes have been identified in the soybean genome.…”

“…To confirm this assumption, differences in this gene between the two parental lines were investigated. At first, the 59 and 39 RACE method was used to obtain the full-length sequence of this phytochrome A gene, which we hereafter refer to as GmPhyA3, since two other phytochrome A genes had been previously designated as GmPhyA1 (AB370252) and GmPhyA2 (AB370253) by Liu et al (2008).…”

“…The inserted sequence was 2.5 kbp in length and was expected to encode a protein of 513 amino acids using the Genscan program (http:/ /genes.mit.edu/ GENSCAN.html). A BLAST search of this inserted sequence indicated that a part of this sequence was highly similar to that of the non-long-terminal-repeat (LTR) retrotransposon reverse transcriptase element, but did not resemble the Ty1/copia or Ty1/gypsy sequences detected in the e4 allele (Liu et al 2008). Moreover, this inserted sequence showed a similar short sequence on both sides of the inserted position ( Figure 3B).…”

“…Although many loci related to soybean flowering and maturity have been identified, and some candidate genes were recognized using near isogenic lines (NILs) (Tasma and Shoemaker 2003), most of the genes responsible for these loci have not yet been isolated except for the E4 gene. Liu et al (2008) reported an association between phytochrome A and photoperiod sensitivity. A retrotransposon sequence inserted into the exon of the e4 allele conferred an early flowering phenotype under long-day conditions extended by incandescent lighting.…”

Photosensitivity plays an essential role in the response of plants to their changing environments throughout their life cycle. In soybean [Glycine max (L.) Merrill], several associations between photosensitivity and maturity loci are known, but only limited information at the molecular level is available. The FT3 locus is one of the quantitative trait loci (QTL) for flowering time that corresponds to the maturity locus E3. To identify the gene responsible for this QTL, a map-based cloning strategy was undertaken. One phytochrome A gene (GmPhyA3) was considered a strong candidate for the FT3 locus. Allelism tests and gene sequence comparisons showed that alleles of Misuzudaizu (FT3/FT3; JP28856) and Harosoy (E3/E3; PI548573) were identical. The GmPhyA3 alleles of Moshidou Gong 503 (ft3/ft3; JP27603) and L62-667 (e3/e3; PI547716) showed weak or complete loss of function, respectively. High red/far-red (R/FR) long-day conditions enhanced the effects of the E3/FT3 alleles in various genetic backgrounds. Moreover, a mutant line harboring the nonfunctional GmPhyA3 flowered earlier than the original Bay (E3/E3; PI553043) under similar conditions. These results suggest that the variation in phytochrome A may contribute to the complex systems of soybean flowering response and geographic adaptation.

“…This wide adaptability is most likely associated with the genetic diversity of the plant (Liu et al, 2008(Liu et al, , 2009 cultivars. These mutations may represent an important source of genes for the development of soybean cultivars adapted to different low-latitude regions or sowing periods in breeding programs (Thakare et al, 2010;Watanabe et al, 2012).…”

-The objective of this work was to determine the inheritance of the long juvenile period trait in natural variants of the Doko, BR 9 (Savana), Davis, Embrapa 1 (IAS 5RC), and BR 16 soybean cultivars. Complete diallel crosses were made between the Doko and BR 16 cultivars and their variants. A 3:1 segregation ratio was observed in the F 2 populations of the 'Doko' x Doko-18T, 'Doko' x Doko-Milionária, 'Davis' x São Carlos, and 'BR 9 (Savana)' x MABR92-836 (Savanão) crosses, indicating that the long juvenile period trait is controlled by a pair of recessive genes. The difference in late flowering between the Doko cultivar and both of its variants was caused by a recessive spontaneous mutation at the same genetic locus. However, the variants Doko-18T and Doko-Milionária are identical mutants that share a pair of genes that control the long juvenile period under short-day conditions. These mutants can be used in breeding programs to develop cultivars adapted to low-latitude tropical regions.Index terms: Glycine max, breeding program, long juvenile period, low-latitude regions, natural mutation, photoperiod. Herança do florescimento tardio em variantes naturais de cultivares de soja em condições de dias curtosResumo -O objetivo deste trabalho foi determinar a herança do caráter período juvenil longo em variantes naturais das cultivares de soja Doko, BR 9 (Savana), Davis, Embrapa 1 (IAS 5RC) e BR 16. Foram realizados cruzamentos em dialelo completo entre as cultivares Doko e BR 16 e as suas variantes. Foi observada segregação 3:1 nas populações F 2 dos cruzamentos 'Doko' x Doko-18T, 'Doko' x Doko-Milionária, 'Davis' x São Carlos e 'BR 9 (Savana)' x MABR92-836 (Savanão), o que indica que o caráter período juvenil longo é controlado por um par de genes recessivos. A diferença de florescimento tardio entre a cultivar Doko e ambas as suas variantes foi causada por uma mutação espontânea recessiva no mesmo loco genético. Entretanto, as variantes Doko-18T e Doko-Milionária são mutantes idênticos que compartilham um par de genes que controlam o período juvenil longo em condições de dia curto. Esses mutantes podem ser usados em programas de melhoramento para desenvolver cultivares adaptadas a regiões tropicais de baixa latitude.Termos para indexação: Glycine max, programa de melhoramento, período juvenil longo, regiões de baixa latitude, mutação natural, fotoperíodo.
