研究及方向Current Research:

  • 种子发育与萌发的生物学调控

结合多组学数据分析与分子生物学技术,对作物种子发育-萌发关键基因进行鉴定,通过遗传分析及基因编辑等策略鉴定其功能并构建调控网络,达到解析作物种子大小、萌发、寿命等重要性状调控机制的目的。

  • 作物品质形成与保持

作物籽粒发育过程中积累的淀粉、蛋白等物质特性决定作物品质;穗发芽(PHS)、陈化等负面影响作物品质。解析品质形成与保持机理,发掘优质性状形成、穗发芽抗性、延缓陈化的关键基因,并解析其内源、外源调控机制,为高产优质作物生物育种奠定基础。

The goal of our group is to understand the environment affection, epigenetic mechanisms, and gene networks that control seed development, dormancy, and germination in cereals. The environment, epigenetic mechanisms, and gene networks affect many essential processes of seed, including embryo development, grain filling, maturation, longevity, and germination. Many of them are necessary for crop production, such as yield, quality, nutrition, and Pre-harvest sprouting (PHS) resistance. PHS is defined as the germination of grains in the ears before harvest, which causes a decrease in end-use quality due to starch and protein degradation. PHS is considered a worldwide disaster that reduces the production of cereals and damages their quality. In recent years, our group is working on the characterization of PHS resistant genes and selecting elite breeding materials.

  • 节节麦单核苷酸多态性揭示小麦D基因组遗传分化与六倍体小麦地理起源

Aegilops tauschii single nucleotide polymorphisms shed light on the origins of wheat D-genome genetic diversity and pinpoint the geographic origin of hexaploid wheat.New Phytologist,2013, 198: 925-937

Hexaploid wheat (Triticum aestivum, genomes AABBDD) originated by hybridization of tetraploidTriticumturgidum(genomes AABB) withAegilops tauschii(genomes DD). Genetic relationships between A. tauschii and the wheat D genome are of central importance for the understanding of the wheat origin and subsequent evolution. Genetic relationships among 477A. tauschiiand wheat accessions were studied with the A. tauschii 10K Infinium single nucleotide polymorphism (SNP) array.Aegilops tauschiiconsists of two lineages (designated 1 and 2) having little genetic contact. Each lineage consists of two closely related sublineages. A population within lineage 2 in the southwestern and southern Caspian appears to be the main source of the wheat D genome. Lineage 1 contributed as little as 0.8% of the wheat D genome. Triticum aestivum is subdivided into the western and Far Eastern populations. The Far Eastern population conserved the genetic make-up of the nascent T. aestivum more than the western population. In wheat, diversity is high in chromosomes 1D and 2D, and it correlates in all wheat D-genome and A. tauschii chromosomes with recombination rates. Gene flow fromA. tauschiiwas an important source of wheat genetic diversity and shaped its distribution along the D-genome chromosomes.

  • 小麦在中国传播历史、适应进化与开花、种子萌发性状选择

Uncovering the dispersion history, adaptive evolution and selection of wheat in China.Plant Biotechnology Journal, 2018, 16: 280-291

Wheat was introduced to China approximately 4500 years ago, where it adapted over a span of time to various environments in agro-ecological growing zones. We investigated 717 Chinese and 14 Iranian/Turkish geographically diverse, locally adapted wheat landraces with 27,933 DArTseq (for 717 landraces) and 312,831 Wheat660K (for a subset of 285 landraces) markers. This study highlights the adaptive evolutionary history of wheat cultivation in China. Environmental stresses and independent selection efforts have resulted in considerable genome-wide divergence at the population level in Chinese wheat landraces. In total, 148 regions of the wheat genome show signs of selection in at least one geographic area. Our data show adaptive events across geographic areas, from the xeric northwest to the mesic south, along and among homoeologous chromosomes, with fewer variations in the D genome than in the A and B genomes. Multiple variations in interdependent functional genes, such as regulatory and metabolic genes controlling germination and flowering time were characterized, showing clear allelic frequency changes corresponding to the dispersion of wheat in China. Population structure and selection data reveal that Chinese wheat spread from the northwestern Caspian Sea region to south China, adapting during its agricultural trajectory to increasingly mesic and warm climatic areas.

  • WheatGmap:小麦基因定位与基因组研究综合平台

WheatGmap: A Comprehensive Platform for Wheat Gene Mapping and Genomic Studies.Molecular Plant,2021, 14: 187-190

Gene mapping of mutations is a critical step for new gene discovery and functional analysis. However, this step has been limited by the discovery of very dense sets of informative markers. Here, we report a platform, Wheat Genomic Map (WheatGmap, https://www.wheatgmap.org), for the fast and cost-effective mapping of genes in wheat. The main application of this platform is the use of several statistical models enabling researchers to simply and flexibly conduct bulked segregant analysis (BSA)-based causal variation mining and gene mapping. A significant feature of the platform is that large-scale genomic variant data can be used as a resource to filter non-causal SNPs or non-validated candidate genes. Moreover, users can share their genomics data of genetic information and annotated phenotypes via WheatGmap. In the current version (WheatGmap 1.0), more than 3,500 next-generation sequencing datasets, including whole-exome sequencing (WES), whole-genome sequencing (WGS), and RNA-seq datasets from public resources, were processed with our standard pipeline. These online tools and genomics data could become an easily applicable resource for gene mapping in a complex wheat genome background.

  • Myb10-D转录因子PHS-3D通过调控ABA合成关键基因NCED增强小麦穗发芽抗性

Myb10-DconfersPHS-3Dresistance to pre-harvest sprouting by regulating NCED in ABA biosynthesis pathway of wheat.New Phytologist2021,230: 1940-1952

Pre-harvest sprouting (PHS), the germination of grain before harvest, is a serious problem resulting in wheat yield and quality losses. Here, we mapped the PHS resistance gene PHS-3D from synthetic hexaploid wheat to a 2.4 Mb presence-absence variation (PAV) region and found that its resistance effect was attributed to the pleiotropicMyb10-Dby integrated omics and functional analyses. Three haplotypes were detected in this PAV region among 262 worldwide wheat lines and 16 Aegilops tauschii, and the germination percentages of wheat lines containingMyb10-Dwas approximately 40% lower than that of the other lines. Transcriptome and metabolome profiling indicated that Myb10-D affected the transcription of genes in both the flavonoid and ABA biosynthesis pathways, which resulted in increases in flavonoids and ABA in transgenic wheat lines. Myb10-D activates NCED by biding the secondary wall MYB-responsive element (SMRE) to promote ABA biosynthesis in early wheat seed development stages. We revealed that the newly discovered function ofMyb10-Dconfers PHS resistance by enhancing ABA biosynthesis to delay germination in wheat. The PAV harboringMyb10-Dassociated with grain color and PHS will be useful for understanding and selecting white-grained PHS resistant wheat cultivars.

  • bHLH转录因子TaPGG1调控FL3蛋白影响谷物籽粒生长与产量

The PGS1 basic helix-loop-helix (bHLH) protein regulates Fl3 to impact seed growth and grain yield in cereals.Plant Biotechnology Journal2022,online

Plant transcription factors, such as basic helix-loop-helix (bHLH) and AT-rich zinc-binding proteins (PLATZ), play criticalrolesin regulating the expression of developmental genesin cereals. We identified the bHLH protein TaPGS1 (T. aestivumPositive Regulator of Grain Size 1) specifically expressed in the seeds at 5–20 days post-anthesis in wheat.TaPGS1was ectopically overexpressed (OE) in wheat and rice, leading to increased grain weight (up to 13.81% in wheat and 18.55% in rice lines) and grain size. Carbohydrate and total protein levels also increased. Scanning electron microscopy results indicated that the starch granules in the endosperm ofTaPGS1OE wheat and rice lines were smaller and tightly embedded in a proteinaceous matrix. Furthermore,TaPGS1 was bound directly to the E-box motif at the promoter of the PLATZ transcription factor genesTaFl3andOsFl3and positively regulated their expression in wheat and rice. In rice, theOsFl3CRISPR/Cas9 knockout lines showed reduced average thousand-grain weight, grain width, and grain length in rice. Our results reveal thatTaPGS1functions as a valuable trait-associated gene for improving cereal grain yield.
