Project description:Maize (Zea mays) is an excellent cereal model for research on seed development because of its relatively large size for both embryo and endosperm. Despite the importance of seed in agriculture, the genome-wide transcriptome pattern throughout seed development has not been well characterized. Using high-throughput RNA sequencing, we developed a spatiotemporal transcriptome atlas of B73 maize seed development based on 53 samples from fertilization to maturity for embryo, endosperm, and whole seed tissues.

Project description:The endosperm of cereal grains feeds the entire world as major food supply, however little is known for its defense responses during endosperm development. Inducer of CBF Expression 1 (ICE1) is a known regulator of cold tolerance in plants. ICE1 has a monocot-specific homologue that is preferentially expressed in cereal grains but with an unclear regulatory function. Here, we characterized the function of monocot-specific ZmICE1 (ZmICE1a) in maize (Zea mays) kernel. mRNA in situ hybridization (ISH) revealed that ZmICE1a is predominantly expressed in the peripheral endosperm (AL, SAL, and BETL). Loss-of-function of ZmICE1a reduced starch content and kernel weight. RNA-seq analysis revealed contradicted expression patterns between starch synthesis genes and genes involved in defense and phytohormone synthesis in zmice1a developing endosperm. Coupled with CUT&Tag-seq analysis, we found that ZmICE1a positively regulates genes in starch synthesis, while negatively regulates genes in AL-specific defense and the synthesis of IAA and JA. Explant assays revealed that exogenous IAA or JA induces the expression of numerous defense genes. mRNA ISH assays revealed that the defense genes induced by IAA and JA, exhibit distinct spatial specific expression in BETL and SAL, respectively. Moreover, we dissected a JA-ZmJAZ9-ZmICE1a-MPI signaling axis involved in JA-mediated defense regulation. Overall, our study revealed ZmICE1a as a key regulatory for endosperm defense responses, and coordinates defense-storage tradeoffs during endosperm development.

Project description:The persistent cereal endosperm constitutes the majority of the grain volume. Dissecting the gene regulatory network underlying cereal endosperm development will facilitate yield and quality improvement of cereal crops. Here, we use single-cell transcriptomics to analyze the developing maize (Zea mays) endosperm during cell differentiation. After obtaining transcriptomic data from 17,022 single cells, we identify 12 cell clusters corresponding to five endosperm cell types and revealing complex transcriptional heterogeneity. We delineate the temporal gene expression pattern from 6 to 7 days after pollination. We profile the genomic DNA binding sites of 161 transcription factors differentially expressed between cell clusters and constructed a gene regulatory network by combining the single-cell transcriptomic data with the direct DNA-binding profiles, identifying 181 regulons containing genes encoding transcription factors along with their high-confidence targets, Furthermore, we map the regulons to endosperm cell clusters, identify cell-cluster-specific essential regulators, and experimentally validated three predicted key regulators. This study provides a framework for understanding cereal endosperm development and function at single-cell resolution.

Project description:Endosperm is a product of double fertilization, and provides nutrients and signals to the embryo during seed development in flowering plants. Early stages of endosperm development are critical for the development of its storage capacity through synthesis and accumulation of starch and storage proteins. Here we report on the isolation and sequencing of mRNAs from the central portion of the starchy endosperm of Zea mays (maize) B73 at 6 days after pollination. We detected high correlation among the four biological replicates of RNAs isolated using laser-capture microdissection of the cell type. Because the assayed stage of development precedes the synthesis and accumulation of the major storage proteins and starch in the endosperm, our dataset likely include mRNAs for genes that are involved in control and establishment of these developmental programs.

Project description:In this work, we performed high throughput sequencing of small RNA libraries in maize (Zea mays ssp. mays) and teosinte (Zea mays ssp. parviglumis) to investigate the response mediated by miRNAs in these plants under control conditions, submergence, drought and alternated drought-submergence or submergence-drought stress. After Illumina sequencing of 8 small RNA libraries, we obtained from 16,139,354 to 46,522,229 raw reads across the libraries. Bioinformatic analysis identified 88 maize miRNAs and 76 miRNAs from other plants differentially expressed in maize and/or in teosinte in response to at least one of the treatments, and revealed that a larger set of miRNAs were regulated in maize than in teosinte in response to submergence and drought stress.
