Plant height is an important agronomic trait, which is governed by multiple genes with major or minor effects. Of numerous QTLs for plant height reported in soybean, most are in large genomic regions, which results in a still unknown molecular mechanism for plant height. Increasing the density of molecular markers in genetic maps will significantly improve the efficiency and accuracy of QTL mapping. This study constructed a high-density genetic map using 4 011 recombination bin markers developed from whole genome re-sequencing of 241 recombinant inbred lines(RILs) and their bi-parents, Zhonghuang 13(ZH) and Zhongpin 03-5373(ZP). The total genetic distance of this bin map was 3 139.15 cM,with an average interval of 0.78 cM between adjacent bin markers. Comparative genomic analysis indicated that this genetic map showed a high collinearity with the soybean reference genome. Based on this bin map, nine QTLs for plant height were detected across six environments, including three novel loci(qPH-b_11, qPH-b_17 and qPH-b_18). Of them, two environmentally stable QTLs qPH-b_13 and qPH-b_19-1 played a major role in plant height, which explained 10.56-32.7% of the phenotypic variance. They were fine-mapped to 440.12 and 237.06 kb region, covering 54 and 28 annotated genes, respectively. Via the function of homologous genes in Arabidopsis and expression analysis, two genes of them were preferentially predicted as candidate genes for further study.

百粒重是决定大豆产量的关键因子,鉴定百粒重相关的QTL和候选基因,进而利用现代分子设计育种技术改良粒大小,是培育大粒高产品种的重要途径。本研究以中黄13和中品03-5373为亲本所构建的重组自交系(recombinant inberd lines,RIL)群体为材料,利用前期构建的高密度Bin图谱和3年6个环境下的百粒重表型,检测到2个在环境间稳定的百粒重相关QTL,分别位于12号和18号染色体。其中qSW12-2表型贡献率为7.31%~11.03%,加性效应为0.52~0.91g,增效等位基因来自中黄13。qSW12-2区间长度为0.19Mb,覆盖20个注释基因,进一步根据候选区间内各基因的组织表达量、注释和双亲多态性分析结果,推测参与油菜素类固醇的生物合成、在籽粒发育期高度表达且携带大效应遗传位点的Glyma.12G195500为百粒重功能基因。基于全基因组重测序数据,多态性分析表明Glyma.12G195500在385份大豆种质资源形成3种单倍型,其中以中黄13为代表的携带H2单倍型的种质资源的百粒重显著高于以中品03-5373为代表的携带H1单倍型的种质资源,H2单倍型在大豆驯化过程中被选择。本研究挖掘的新位点可为进一步揭示大豆百粒重的遗传机制和培育高产大豆新品种奠定基础。

Dysregulation of neurotransmitter metabolism in the central nervous system contributes to mood disorders such as depression, anxiety, and post–traumatic stress disorder. Monoamines and amino acids are important types of neurotransmitters. Our previous results have shown that disco-interacting protein 2 homolog A(Dip2a) knockout mice exhibit brain development disorders and abnormal amino acid metabolism in serum. This suggests that DIP2A is involved in the metabolism of amino acid–associated neurotransmitters. Therefore, we performed targeted neurotransmitter metabolomics analysis and found that Dip2a deficiency caused abnormal metabolism of tryptophan and thyroxine in the basolateral amygdala and medial prefrontal cortex. In addition, acute restraint stress induced a decrease in 5-hydroxytryptamine in the basolateral amygdala. Additionally, Dip2a was abundantly expressed in excitatory neurons of the basolateral amygdala, and deletion of Dip2a in these neurons resulted in hopelessness-like behavior in the tail suspension test. Altogether, these findings demonstrate that DIP2A in the basolateral amygdala may be involved in the regulation of stress susceptibility. This provides critical evidence implicating a role of DIP2A in affective disorders.
