Project description:Bulked segregant analysis (BSA) is an efficient method to rapidly and efficiently map genes responsible for mutant phenotypes. This procedure, however, requires access to quantitative genetic markers that are polymorphic in the mapping population. We have developed a modification of BSA (BSR-Seq) that makes use of RNA-Seq reads to efficiently map genes even in populations for which no polymorphic markers have been previously identified. Because of the digital nature of next-generation sequencing (NGS) data, it is possible to conduct de novo SNP discovery and quantitatively genotype BSA samples using the same RNA-Seq data. In addition, analysis of the RNA-Seq data provides information on the effects of the mutant on global patterns of gene expression at no extra cost. In combination these results greatly simplify gene cloning experiments. To demonstrate the utility of this strategy BSR-Seq was used to clone the glossy3 (gl3) gene of maize. Mutants of the glossy loci exhibit altered accumulation of epicuticular waxes on juvenile leaves. We previously generated a large collection of glossy mutants using the Mu transposon system. By subjected a reference allele to BSR-Seq, we were able to map the gl3 locus to a ~2.3Mb interval that is consistent with the results of prior mapping experiments. The single gene located in the 2.3Mb mapping interval that contained a Mu insertion and whose expression was down-regulated in the mutant pool was subsequently demonstrated to be the gl3 gene via the analysis of multiple independently Mu transposon induced mutant alleles. The gl3 gene encodes a putative myb transcription factor, which directly or indirectly affects the expression of a number of genes involved in the biosynthesis of very-long-chain fatty acids.

Project description:Small peptides (sPeptides), a class of biological molecules of less than 100 amio acids encoded by small open reading frames (sORFs), play important roles in multiple biological process. Here, we conducted a comprehensive study using mRNA-seq, Ribo-seq, and Mass Spectrometry (MS) on six tissues (each with at least two replicates) of maize, set up a bioinformatic pipeline, and performed a genome-wide scan of sORFs and sPeptides in maize. Our study sets up a guildline for the genome-wide scan of sORFs and sPeptides in plants by integrating Ribo-seq, and MS data, provides a more comprehensive resource of functional sPeptides in maize, and sheds light on the complex biological system of plants in a new perspective.

Project description:This research identifies a novel protein required for paramutation at the maize purple plant1 locus. This 'required to maintain repression2' (RMR2) protein represents the founding member of a plant-specific clade of hypothetical proteins. We show that RMR2 is required for transcriptional repression at the Pl1-Rhoades haplotype, for accumulation of 24 nt RNA species, and for maintenance of a 5-methylcytosine pattern distinct from that maintained by RNA polymerase IV. Genetic tests indicate that RMR2 is not required for paramutation occurring at the red1 locus. These results distinguish the paramutation-type mechanisms operating at specific haplotypes. The RMR2 clade of proteins provides a new entry point for understanding the diversity of epigenomic control operating in higher plants.
