Project description:We hypothesized that the genome segments of cultivated barley should show certain similarity with its ancestral wild barley. Instead of whole genome sequences, we employed RNA-Seq to investigated the genomic origin of modern cultivated barley using some representative wild barley genotypes from the Near East and Tibet, and representative world-wide selections of cultivated barley.

Project description:Abstract: Multiple nodes and dwarf mutants in barley are a valuable resource for identifying genes that control shoot branching, vegetative growth, and development. In this study, physiological, microscopic and genetic analylsis were conducted to characterize and fine-map the underling gene of A a barley mutant with Multiple Stem Nodes and Spikes and Dwarf (msnsd) , which was selected from EMS- and 60Co-treated barley cv. Edamai 934 (E934) to characterize the mutant and fine-map its underlying gene. The msnsd mutant had more stem nodes and , lower plant height and a shorter plastochron than Edamai 934the wild type. Moreover, the mutant had two or more spikes on each tiller., emerging from the lower nodes or the base of the top spike, and a shorter plastochron. Microscopic analysis showed that the dwarf phenotype of msnsd resulted from reduced cell lengths and cell numbers in the stem. Further physiological analysis showed that msnsd was GA3-deficient, with its plant height increasing after external GA3 application. Genetic analysis revealed that a single recessive nuclear gene, namely, HvMSNSD, controlled the msnsd phenotype. Using a segregating population derived from Harrington and the msnsd mutant, HvMSNSD was fine-mapped on chromosome 5H in a 200 kb interval using bulked segregant analysis (BSA) coupled with RNA-sequencing (BSR-seq), with a C-T substitution in the exon of HvTCP25 co-segregating with the msnsd phenotype. RNA-seq analysis showed that a gene encoding gibberellin 2-oxidase 8, a negative regulator of GA biosynthesis, was upregulated in the msnsd mutant. Transcriptomic analysis identified several Several known genes related to inflorescence development that were also upregulated and enriched in the msnsd mutant. Collectively, we propose that HvMSNSD regulates the plastochron and morphology of reproductive organs, likely by coordinating GA homeostasis and changed expression of floral development related genes in barley. this This study offers valuable insights into the molecular regulation of barley plant architecture and inflorescence development

Project description:A DNA microarray analysis detected large-scale changes of gene expression in response to Cd stress with a substantial difference between the two barley genotypes differing in Cd tolerance and accumulation. Cd stress led to higher expression of genes involved in transport, carbohydrate metabolism and signal transduction in the low-grain-Cd-accumulating genotype. Novel transporter genes such as zinc transporter genes were identified as being associated with low Cd accumulation. We used microarrays to understand the mechanism of low Cd accumulation in crops which is crucial for sustainable safe food production in Cd-contaminated soils.
