Project description:Barley spikelet abortion transcriptome

| PRJEB51366 | ENA

RNA-Seq of developing shoot apical meristems of barley cultivar Bonus and two allelic praematurum-c/mat-c mutants mat.c.907 (NGB 116862) and mat.c.943 (NGB 117474) grown under long- and short-day photoperiods

Project description:Natural variation in the barley homolog of CENTRORADIALIS (HvCEN), was found to contribute to the expansion of barley cultivation into diverse habitats. It has been shown that induced hvcen mutants, originally designated as praematurum-c/maturity-c (mat-c) mutants, flowered a few days earlier under natural long-day conditions. All hvcen mutants flowered early and showed a reduction in spikelet number per spike, tiller number and yield in the outdoor experiments. Further evaluating development of main shoot apex of hvcen mutants and wild type under controlled long day and short day conditions showed that mutations in hvcen accelerated spikelet initiation and reduced axillary bud number in a photoperiod independent manner, but promoted floret development only under long days. In this project we investigate the pleiotropic effects of HvCEN on developmental timing and shoot and spike morphologies of barley and dependence on these effects on photoperiod. This RNAseq dataset was generated to identify the putative transcriptional targets of HvCEN. To this end, we used global transcriptome profiling in developing shoot apices and inflorescences of two allelic hvcen mutants (mat-c.907 and mat-c.943) and wild-type (Bonus) plants grown under long- and short-day photoperiods.

RNA-Seq of developing shoot apical meristems of barley cultivar Golden Promise (null segregant and Ubi::HvFT3 overexpressor) grown under long- and short-day photoperiods

Project description:FLOWERING LOCUS T-like genes have duplicated and functionally diverged between dicot and monocots species. The purpose of this study was to characterize the function of HvFT3 in barley (Hordeum vulgare). For this purpose, we generated transgenic lines overexpressing HvFT3 and characterized its effects on global gene expression changes in the main shoot apices at two developmental stages (spikelet initiation, lemma primordium). Analysing the function of different HvFT homologs in barley gives important insights into the genetic control of spike development and hence of yield in barley.

RNA-seq data from spikelet tissues of cultivated two-row European spring barley genotypes.

Project description:In this project we developed a data resource based on a historical collection of 209 two-row European spring barley genotypes. The population is representative of pan-European breeding progress across the years from 1830 to 2014. The dataset comprises gene expression data generated by RNA-sequencing data of six different tissues across a range of developmental stages. This submission contains the spikelet tissue samples.

RNA-seq performed on Brassica oleracea var. italica (broccoli) control and blindness-affected plants, sampled from both leaves and roots.

Project description:Blindness, characterized by apical abortion, is a physiological condition that affects the Brassica family. While exposure to low temperatures during early development has been associated with blindness, the underlying causes and their impact on proper development remain unknown. This study aims to investigate the mechanisms involved in blindness occurrence in broccoli plants.

Setaria viridis small RNAs from panicle tissues

Project description:A total of 18 libraries from Setaria viridis were constructed using the Illumina TruSeq sample preparation method. We used two biological replicate libraries from the leaf, whole panicles (inside leaf sheath), whole panicles (coming out of leaf sheath), whole panicles (completely out of leaf sheath), whole panicles (completely out of leaf sheath, after pollination), spikelet (inside leaf sheath), spikelet (coming out of leaf sheath), and spikelet (completely out of leaf sheath).
