Project description:The goal of this study was to examine the transcriptional response of maize and sorghum during compatible and incompatible interactions with Setosphaeria turcica.
Project description:The classical maize mutant lazy1 (la1), displayed prostrate growth with reduced shoot gravitropism. We compared the transcriptome profile of the third node in la1-ref mutants with those in wild-type plants using RNA-SEQ to examine the genome-wide effect of the ZmLA1 gene. We generated 14.6 and 36.5 million paired-end reads from two biological samples of wild-type and la1-ref mutant plants, respectively.
Project description:We explored the gene expression profiles of developing maize kernel by RNA sequencing. Our purpose was to explore the sequence diversity across the inbred lines, especially in the gene regions, and to discover the gene regulatory networks employed in immature maize kernels.
Project description:MOP1-mediated regulation of gene expression of plant responses to early ABA induction has transcriptionally and physiologically relevant roles. Homozygous mop1-1 plants are compromised in their ability to recover from water deprivation. Purpose: Genome-wide identification of immediate and direct MOP1-dependent ABA transcriptional responses Methods: mRNA profiles of Mop1 wildtype and mop1-1 mutant V3 stage maize seedlings were subjected to ABA and MS treatments for 1 hour. The trimmed sequence reads were analyzed at the gene level using HISAT2, stringite, and edgeR. Results: we mapped ~33 million, 150 bp, paired-end sequence reads per sample to the B73 version 4 maize genome and identified 1,856 genes in four pairwise-comparisons to be differentially expressed genes (DEGs) with a log2FC ≥ 0.95 and FDR <0.05, 1,119 DEGs were found to be unique to one genotype/treatment comparison. Conclusions: MOP1-mediated regulation of gene expression in maize seedlings in the RdDM (mop1-1) mutant has relevant transcriptional and physiological roles in plants subjected to stress. Our study generated by RNA-seq technology identified genes and biological processes regulated by RdDM and ABA-mediated stress responses, including MOP1-dependent and immediate response genes (MIMs).
Project description:Maize is one of the most important crops in the world and serves as an excellent model for seed development research. Despite the important role of the transcriptome in development, genome-wide expression throughout the process of maize seed development has not been characterized. Using RNA-seq, we developed a spatio-temporal transcriptome atlas of B73 maize seed development from fertilization to maturity for embryo, endosperm, and whole seed tissue.
Project description:These data include RNA-seq, circRNA-seq, and small RNA-seq of transcriptome, Ribo-seq of translatome and protein protein binary interactions by recombination-based library vs. library yeast-2-hybrid throughout the lifecycle of the maize inbred line B73.

Project description:Through hierarchical clustering of transcript abundance data across a diverse set of tissues and developmental stages in maize, we have identified a number of coexpression modules which describe the transcriptional circuits of maize development.
