Decoupling Brace Root Development from Shoot Development in Sorghum: Candidate Genes Revealed by GWAS

ABSTRACT: Brace roots develop from stem nodes above the soil and are important for structural support. While the function of brace roots has been previously shown, the causative genes for brace root development have yet to be identified in sorghum. Here we used 3’ RNA sequencing in BTx623 sorghum stem nodes to determine if candidate genes from a complimentary Genome Wide Association (GWA) analysis were expressed. Of the 25 candidate genes identified in GWA analysis, 15 were expressed in at least one of the three stem nodes. Together, the combined approach of GWA analysis and RNA-sequencing analysis provides a strong foundation for identifying the causative genes for brace root development.

RNA-Seq and BS-Seq of Sorghum bicolor tissues

Project description:This experiment contains the subset of data corresponding to sorghum RNA-Seq data from experiment E-GEOD-50464 (http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-50464/), which goal is to examine the transcriptome of various Sorghum bicolor (BTx623) tissues: flowers, vegetative and floral meristems, embryos, roots and shoots. Thus, we expanded the existing transcriptome atlas for sorghum by conducting RNA-Seq analysis on meristematic tissues, florets, and embryos, and these data sets have been used to improve on the existing community structural annotations.

Sorghum nitrogen stress tolerance

Project description:Sorghum is an important cereal crop, which requires large quantities of nitrogen fertilizer for achieving commercial yields. Identification of the genes responsible for low-N tolerance in sorghum will facilitate understanding of the molecular mechanisms of low-N tolerance, and also facilitate the genetic improvement of sorghum through marker-assisted selection or gene transformation. In this study we compared the transcriptomes of root tissues from seven sorghum genotypes having different genetic backgrounds with contrasting low-N tolerance by the RNAseq deep sequencing data. Several genes were found which are common differentially expressed genes between four low-N tolerant sorghum genotypes (San Chi San, China17, KS78 and high-NUE bulk) and three sensitive genotypes (CK60, BTx623 and low-NUE bulk).

Variation in gene expression between two Sorghum bicolor lines differing in innate immunity response

Project description:Comparative RNA-seq analysis of MAMP triggered gene expression in two sorghum bicolor lines, BTx623 and SC155-14E, revealed a clear transcriptional response to elicitation with the microbe associated molecular pattern (MAMPs) flagellin (flg22) or chitin elicitation.

RNA-Seq of Sorghum bicolor 9d seedlings in response to osmotic stress and abscisic acid

Project description:This study utilized next generation sequencing technology (RNA-Seq) to examine the transcriptome of sorghum plants challenged with osmotic stress and exogenous abscisic acid (ABA) to elucidate those genes and gene networks that contribute to sorghum's tolerance to water-limiting environments with a long-term aim of developing strategies to improve plant productivity under drought. We examined the mRNA of 9 day old Sorghum bicolor (BTx623) from 2 tissue types (roots and shoots) for 2 treatments (20 uM ABA and 20% PEG) with corresponding controls (0.2M NaOH and H2O) for 27 hrs prior to harvesting, each done in triplicate biological replicates - resulting in 24 unique runs
