...-pollinating crops like wheat ( Triticum aestivum ), the post-anthesis viability of unpollinated carpels has been overlooked, despite its importance for hybrid seed production systems. To advance our knowledge of carpel development in the absence of pollination, we created a high-throughput phenotyping...

...; however, the functions of three wheat ( Triticum aestivum ) AGL6 genes are still unclear. Here, we report the main functions of wheat AGL6 homoeologous genes in stamen development. In RNAi plants, stamens showed abnormality in number and morphology, and a tendency to transform into carpels. Consistently...

...Chengxia Li; Huiqiong Lin; Andrew Chen; Meiyee Lau; Judy Jernstedt; Jorge Dubcovsky ABSTRACT The spikelet is the basic unit of the grass inflorescence. In this study, we show that wheat MADS-box genes VRN1 , FUL2 and FUL3 play critical and redundant roles in spikelet and spike development, and also...

...Juan Manuel Debernardi; Huiqiong Lin; George Chuck; Justin D. Faris; Jorge Dubcovsky Wheat domestication from wild species involved mutations in the Q gene. The q allele (wild wheats) is associated with elongated spikes and hulled grains, whereas the mutant Q allele (domesticated wheats) confers...

...Julian R. Greenwood; E. Jean Finnegan; Nobuyoshi Watanabe; Ben Trevaskis; Steve M. Swain The advantages of free threshing in wheat led to the selection of the domesticated Q allele, which is now present in almost all modern wheat varieties. Q and the pre-domestication allele, q , encode an AP2...

...R. B. Flavell; M. O’Dell ABSTRACT Chromosome marking by cytosine methylation has been examined in two gene systems in wheat - at the loci encoding high molecular weight (BMW) glutenin sub-units (seed proteins) and ribosomal RNA. Variation in cytosine methylation occurs between progeny in highly...
