“…Using traditional genetic analysis, there have been several reports of QTL controlling TN in wheat. To date, at least four single genes ( tin1 , tin2 , tin3 , and ftin ) that control TN have been reported ( Peng et al, 1998 ; Spielmeyer and Richards, 2004 ; Kuraparthy et al, 2007 ; Zhang et al, 2013 ). To date, several QTL have been associated with TN mapped to chromosomes 1A, 2B, 2A, 2B, 2D, 3A, 3B, 3D, 4D, 5A, 5D, 6D, 7A, and 7B ( Kato et al, 2000 ; Li et al, 2010 ; Deng et al, 2011 ; Naruoka et al, 2011 ; Nasseer et al, 2016 ; Wang et al, 2016 ; Hu et al, 2017 ; Xu et al, 2017 ).…”

Maximum tiller number and productive tiller number are important traits for wheat grain yield, but research involving the temporal expression of tiller number at different quantitative trait loci (QTL) levels is limited. In the present study, a population set of 371 recombined inbred lines derived from a cross between Chuan-Nong18 and T1208 was used to construct a high-density genetic map using a Wheat55K SNP Array and to perform dynamic QTL analysis of the tiller number at four growth stages. A high-density genetic map containing 11,583 SNP markers and 59 SSR markers that spanned 4,513.95 cM and was distributed across 21 wheat chromosomes was constructed. A total of 28 single environmental QTL were identified in the recombined inbred lines population, and among these, seven QTL were stable and used for multi-environmental and dynamic analysis. These QTL were mapped to chromosomes 2D, 4A, 4D, 5A, 5D, and 7D, respectively. Each QTL explained 1.63–21.22% of the observed phenotypic variation, with an additive effect from -20.51 to 11.59. Dynamic analysis showed that cqTN-2D.2 can be detected at four growth stages of tillering, explaining 4.92–17.16% of the observed phenotypic variations and spanning 13.71 Mb (AX-109283238-AX-110544009: 82189047-95895626) according to the physical location of the flanking markers. The effects of the stable QTL were validated in the recombined inbred lines population, and the beneficial alleles could be utilized in future marker-assisted selection. Several candidate genes for MTN and PTN were predicted. The results provide a better understanding of the QTL selectively expressing the control of tiller number and will facilitate future map-based cloning. 9.17% SNP markers showed best hits to the Chinese Spring contigs. It was indicated that Wheat55K Array was efficient and valid to construct a high-density wheat genetic map.

WD-40 repeat-containing protein MSI4 (FVE)/MSI4 plays important roles in determining flowering time in Arabidopsis. However, its function is unexplored in wheat. In the present study, coimmunoprecipitation and nanoscale liquid chromatography coupled to MS/MS were used to identify FVE in wheat (TaFVE)-interacting or associated proteins. Altogether 89 differentially expressed proteins showed the same downregulated expression trends as TaFVE in wheat line 5660M. Among them, 62 proteins were further predicted to be involved in the interaction network of TaFVE and 11 proteins have been shown to be potential TaFVE interactors based on curated databases and experimentally determined in other species by the STRING. Both yeast two-hybrid assay and bimolecular fluorescence complementation assay showed that histone deacetylase 6 and histone deacetylase 15 directly interacted with TaFVE. Multiple chromatin-remodelling proteins and polycomb group proteins were also identified and predicted to interact with TaFVE. These results showed that TaFVE directly interacted with multiple proteins to form multiple complexes to regulate spike developmental process, e.g. histone deacetylate, chromatin-remodelling and polycomb repressive complex 2 complexes. In addition, multiple flower development regulation factors (e.g. flowering locus K homology domain, flowering time control protein FPA, FY, flowering time control protein FCA, APETALA 1) involved in floral transition were also identified in the present study. Taken together, these results further elucidate the regulatory functions of TaFVE and help reveal the genetic mechanisms underlying wheat spike differentiation.

“…In wheat, only a couple of genes have been reported to affect plant architecture related traits: genes including tin1 (tiller inhibition gene 1), tin2 (tiller inhibition gene 2), tin3 (tiller inhibition gene 3) and ftin (fertile tiller inhibition) gene,are regulators for tiller inhibition [17][18][19][20][21]; Q gene is associated with spike compactness [22]. However, the effects of OsSPL14 ortholog, TaSPL14 on wheat plant architecture and yield is still largely unexplored.…”

Background SQUAMOSA PROMOTER-BINDING PROTEIN-BOX gene OsSPL14 from rice is evaluated as the major gene for ideal plant architecture consisting of few unproductive tillers, more grains per spike and high lodging resistance stems. However, the function of its orthologous gene TaSPL14 in wheat is still unknown. Results Here, we reported the similarity and variation between TaSPL14 and OsSPL14. Similar to OsSPL14, TaSPL14 knock-out mutants exhibited decreased plant height, spike length, spikelet number, thousand-grain weight. Different from OsSPL14, TaSPL14 had no effect on tiller number. Transcriptome analysis genes related to ethylene response were significantly decreased in young spikes of TaSPL14 knockout mutants, compared with wild type. TaSPL14 directly binds to the promoters of the ethylene response gene TaEIL1 (EIN3-LIKE 1), TaRAP2.11 (ETHYLENE-RESPNSIVE TRANSCRIPTION FACTOR 2.11) and TaERF1 (ETHYLENE-RESPNSIVE TRANSCRIPTION FACTOR 1) and activities their expression, suggesting that TaSPL14 might regulate wheat spike development through ethylene response pathway. Conclusions TaSPL14 had similar function with OsSPL14 in regulating plant height, spike length, spikelet number and thousand-grain weight of wheat, and had different function in tiller development. TaSPL14 might regulate spike development through TaEIL1, TaRAP2.11 and TaERF1, not TaDEP1.The elucidation of TaSPL14 will contribute to exploring the molecular mechanisms underlying plant architecture of wheat.
