Chromatin immunoprecipitation of MADS29 to find the cis regulatory regions and targets of this transcription factor

Project description:A ChIP-seq analysis revealed 378 targets of OsMADS29, which include genes involved in cytokinin metabolism and auxin signaling, carbohydrate metabolism, transporters and a large number of transcription factors, reflecting on its functional diversity. Chromatin Immunonoprecipitation of MADS29 using antiMADS29 antibody was done using rice 9 DAP seed tissue with total input chromatin and mock immunoprecipitated chromatin as controls

ZmEREB92 plays a negative role in seed germination by regulating ethylene signaling and starch mobilization in maize

Project description:Rapid and uniform seed germination is required for modern cropping system. Thus, it is important to optimize germination performance through breeding strategies in maize, in which identification for key regulators is needed. Here, we characterized an AP2/ERF transcription factor, ZmEREB92, as a negative regulator of seed germination in maize. Enhanced germination in ereb92 mutants is contributed by elevated ethylene signaling and starch degradation. Consistently, an ethylene signaling gene ZmEIL7 and an α-amylase gene ZmAMYa2 are identified as direct targets repressed by ZmEREB92. OsERF74, the rice ortholog of ZmEREB92, shows conserved function in negatively regulating seed germination in rice. Importantly, this orthologous gene pair is likely experienced convergently selection during maize and rice domestication. Besides, mutation of ZmEREB92 and OsERF74 both lead to enhanced germination under cold condition, suggesting their regulation on seed germination might be coupled with temperature sensitivity. Collectively, our findings uncovered the ZmEREB92-mediated regulatory mechanism of seed germination in maize and provide breeding targets for maize and rice to optimize seed germination performance towards changing climates.

Identification of Genes and miRNAs Affecting Pre-harvest Sprouting in Rice (Oryza sativa L.) by Transcriptome and Small RNAome Analyses

Project description:Purpose: The goal of our study is to compare two different ecotypes of Oryza sativa L., PHS-susceptible rice trait and PHS-resistant rice trait under three different maturation stages in rice seed embryo with profile of miRNA-seq. Methods: Oryza sativa. L miRNA profiles of two different ecotypes with 3 different maturation stages of rice seed embryo were generated by NGS, in duplicate, following Illumina NGS workflow. Results: We found the differentially expressed microRNAs between PHS-susceptible rice trait and PHS-resistant rice trait according to the three different seed maturation stages. Target transcripts of differentially expressed microRNAs have been predicted via psRNATarget web server, and a part of those target genes are likely to be regulated by microRNAs, affecting overall responses to heat stress and the regulation of seed dormancy during maturation. Conclusions: Our study represents the analysis of rice seed small RNAs, specifically microRNAs, under two different ecotypes, three different seed maturation stages in rice seed embryo. Our results show that microRNAs are involved in response to heat stress and the regulation of seed dormancy. This study will provide a foundation for understanding dynamics of seed dormancy during the seed development and overcoming pre-harvest sprouting.

Expression data from rice seeds during low temperature treatment

Project description:As a species mostly planted in tropical and subtropical regions, rice is sensitive to chilling temperature, especially at reproductive stage. However, the effect of low temperature on seed development has not been well characterized. The transcriptome of two rice cultivars Zhonghua11 and Hanfeng were analyzed to characterize the gene regulatory networks of rice seed during low temperature treatment. Whole plants of two rice cultivars Zhonghua11 (low temperature sensitive) and Hanfeng (low temperature tolerance) were treated at 14°C for 2 days during seed development stage. The plants without treatment serve as controls. Rice seeds were harvested for RNA extraction.

Hierarchical transcriptional network controls appressorium-mediated plant infection by the rice blast fungus Magnaporthe oryzae

Project description:We report that the homeobox trasncription factor called HOX7 controls hyphae-associated genes, autophagy and cell cycle related genes necessary for appressorium development in the rice blast fungus Magnaporthe oryzae. We also report that the ste transcription factor MST12 regulates gene functions involved in septin reorientation.

Expression data from additional fertilization rice seeds

Project description:Carbon (C) and nitrogen (N) contents of grain-filling stage are keys item that determined the growth of rice, and also the quality of seed. Therefore, to elucidating the mechanism of C/N signaling in a seed is an important problem for crops whose seed is used as food like rice. The DNA microarray analysis with the rice seed which was performed the additional fertilizer at the time of heading, in order to clarify how C/N signal change of the rhizosphere in seed production stage affects a seed component on a gene expression level.

Identification of LEC1 target genes

Project description:The transcription factor (TF) LEAFY COTYLEDON1 (LEC1) acts as an essential regulator of Arabidopsis embryogenesis and seed development. It controls aspects of early embryogenesis such as cotyledon identity and suspensor morphology, as well as seed maturation processes such as storage compound accumulation, acquisition of desiccation tolerance and dormancy. To identify downstream components of the LEC1 regulon, dexamethasone-regulated expression of LEC1 and ChIP/chip were applied and revealed the enrichment of phytohormone- as well as elongation-related genes among LEC1 target genes.
