Six-rowed barley originated from a mutation in a homeodomain-leucine zipper I-class homeobox gene.
Increased seed production has been a common goal during the domestication of cereal crops, and early cultivators of barley (Hordeum vulgare ssp. vulgare) selected a phenotype with a six-rowed spike that stably produced three times the usual grain number. This improved yield established barley as a founder crop for the Near Eastern Neolithic civilization. The barley spike has one central and two...
متن کاملSix-Rowed Spike3 (VRS3) Is a Histone Demethylase That Controls Lateral Spikelet Development in Barley.
The complex nature of crop genomes has long prohibited the efficient isolation of agronomically relevant genes. However, recent advances in next-generation sequencing technologies provide new ways to accelerate fine-mapping and gene isolation in crops. We used RNA sequencing of allelic six-rowed spike3 (vrs3) mutants with altered spikelet development for gene identification and functional analy...
متن کاملSix-rowed spike4 (Vrs4) controls spikelet determinacy and row-type in barley.
Inflorescence architecture of barley (Hordeum vulgare L.) is common among the Triticeae species, which bear one to three single-flowered spikelets at each rachis internode. Triple spikelet meristem is one of the unique features of barley spikes, in which three spikelets (one central and two lateral spikelets) are produced at each rachis internode. Fertility of the lateral spikelets at triple sp...
متن کاملMolecular characterization of mlo mutants in North American two- and six-rowed malting barley cultivars.
SUMMARY Barley lines PRU1, URS1 and URS2 represent three candidate mlo mutants induced in either the two-rowed cultivar Prudentia or the six-rowed cultivar Ursula. Both Prudentia and Ursula are North American malting barley varieties with specific malting properties. Here, we analysed the three candidate mutants at the molecular level. We identified lesions in the Mlo gene of all three lines, c...
متن کاملRegistration of Seven Spring Two-Rowed Barley Germplasm Lines Resistant to Russian Wheat Aphid
230 Journal of Plant Registrations, Vol 2, No. 3, September 2008 Devastating yield losses occurred in wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) in the western United States within 2 yr after the fi rst appearance of the Russian wheat aphid [RWA; Diuraphis noxia, (Mordvilko)] in 1986 (Porter et al., 1999). Screening of the entire USDA-ARS National Small Grains Collection of H....
