The purpose of this study was to characterize Ta14 S homoeologs and assess their functions in wheat seed *** genomic and c DNA sequences of three Ta14 S homoeologous genes encoding 14-3-3 proteins were *** analysis revealed that the three homoeologs consisted of five exons and four introns and were very highly conserved in the coding regions and in exon/intron structure,whereas the c DNA sequences were variable in the 5′ and 3′-*** three genes,designated as Ta14S-2A,Ta14S-2B and Ta14S-2D,were located in homoeologous group 2 *** polypeptide chains of the three Ta14 S genes were highly *** genes were most homologous to Hv14 A from ***-time quantitative PCR indicated that the three Ta14 S genes were differentially expressed in different organs at different developmental stages and all exhibited greater expression in primary roots of 1-day-old germlings than in other *** of the expression patterns of the three homoeologous genes at different times after pollination also revealed that their expression was developmentally *** transcription of Ta14S-2B was clearly higher during seed germination,whereas expressions of Ta14S-2A and Ta14S-2D were up-regulated at the beginning of seed imbibition(0–12 h),but declined *** results suggested that the three Ta14 S homoeologous genes have regulatory roles in seed development and germination.

We previously introgressed Sul-Phl,one of two Aegilops speltoides suppressors of Ph1 gene,into tetraploid durum wheat cv Langdon(LDN).Here,to evaluate its utility for introgression of alien germplasm into durum wheat,we constructed LDN plants heterozygous for Sul-Ph1 that contained a single LDN chromosome 5 B and a single *** chromosome 5 S and targeted these two monosomes for *** genotyped 28 BC F and 84 F progeny with the wheat Illumina 90 K single nucleotide polymorphism(SNP) assay and detected extensive recombination between the two *** on segregation of 237 SNP markers in the BC F population and 220 in the F population we constructed maps,which were 65.31 and 63.71 cM long,*** compared recombination rates along the homoeologous chromosomes with recombination rates along 5 B *** rates between the two homoeologous chromosomes were double the rate expected based on meiotic pairing between them,which we attributed to selection against aneuploid gametes in tetraploid *** rates were similar in the distal region of the long arm but declined more precipitously between homoeologues than between homologues in the proximal *** an unknown reason,we obtained almost no recombination in the short arm between the *** showed by non-denaturing fluorescence in situ hybridization(ND-FISH) that chromosome 5 S was recombined with 5 D in the substitution line that was the source of the 5 S chromosome in our *** analysis of recombination between 5 B and 5 S induced by Su1-Ph1 showed that the suppressor is a valuable tool for inducing gene introgression in tetraploid wheat.
