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

ABSTRACT: 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.
