Common wheat (Triticum aestivum) is a hexaploid plant (AABBDD) derived from genetically related tetra-ploid wheat T. turgidum (AABB) and a diploid goatgrass Aegilops tauschii (DD). Recent advances in sequencing technology and genome assembly strategies allow the acquisition of multiple wheat gen-omes, calling for a centralized database to store, manage and query the genomics information in a man-ner to reflect their evolutionary relationship and to perform effective comparative genome analysis. Here, we built WheatGene, a database that contains five wheat genomes of 318,102 genes and 945,900 tran-scripts and their expression information in 998 RNA-seq samples that can be searched and compared in an interactive manner. WheatGene was developed with Drupal, a popular content management system and the toolkit Tripal managed the biological information. The database was accessible through a web browser with species, search, gene expression, tools, and literature entries. Tools available were BLAST, synteny viewer, map viewer, JBrowse, data downloads, gene expression heatmap and bar chart, and homologs viewer. Moreover, the map viewer connected genomics data with genetic maps and QTL that can be searched for markers for molecular breeding. WheatGene was developed with open-source mod-ules and libraries. WheatGene is available at http://wheatgene.agrinome.org.

Wheat leaf rust is a prevalent foliar disease in wheat worldwide. Growing resistant cultivars is an effec-tive strategy to minimize the impact of leaf rust on yield and grain quality. Lr42 is a leaf rust resistance gene identified from Aegilops tauschii a
The anther cuticle and pollen exine play a critical role in male gametophyte development. The sporopol-lenin precursors and cuticular lipid monomers are transported to the surface of the microspores and the epidermis by lipid transport proteins (LTPs) and
In rice, high-temperature stress (HT) during flowering results in decreased grain yield via a reduction in spi-kelet fertility;however, the effect of plant water status on spikelet fertility under HT remains unknown. To investigate the relationship betwee
Male sterility is a common biological phenomenon in plant kingdom and has been used to generate male-sterile lines, which are important genetic resources for commercial hybrid seed production. Although increasing numbers of male-sterility genes have been
A nuclear-encoded sigma (σ) factor is essential for the transcriptional regulation of plant chloroplast- encoded genes. Five putative maizeσfactors have been identified by database searches, but their func- tions are unknown. We report a maize leaf color
TaMs1 encodes a non-specific lipid transfer protein (nsLTP) and is required for pollen development in wheat. Although MS1 is a Poaceae-specific gene, the roles of MS1 genes in other Poaceae plants are unknown, especially in rice and maize. Here, we identi
The Nsa cytoplasmic male sterility (CMS) system confers stable male sterility and offers great potential for production of hybrid seeds in oilseed rape. However, genes responsible for male sterility in Nsa CMS have not been identified. By mitochondrial ge
Simple sequence repeat (SSR) markers have been proved to be a very powerful tool for quantitative trait locus (QTL) mapping, marker-assisted selection and comparative genomics research in many crop spe-cies. However, a high-density SSR genetic linkage map
Poor filling and low weight of inferior kernels limit the further improvement of wheat yield. Two culti-vars, Shuangda 1 and Xinong 538, with different grain weights, were selected to investigate the physio-logical changes of inferior kernels by removal o
Deep placement of nitrogen fertilizer is a key strategy for improving nitrogen use efficiency. A two-year field experiment was conducted during the early rice growing seasons (March-July) of 2016 and 2017. The experimental treatments comprised two rice cu
