MADS-box genes form a large family of transcription factors and play important roles in flower development and organ differentiation in plants. In this study, 42 wheat cDNAs encoding putative MADS-box genes were isolated. BLASTX searches and phylogenetic analysis indicated that the cDNAs represented 12 of the 14 MADS-box gene subfamilies. TaAGL14 and(More)
Wheat prolamin-box binding factor (WPBF), a DOF transcription factor previously was isolated from wheat endosperm and suggested to function as an activator of prolamin gene expression during seed development. In this study, we showed that WPBF is expressed in all wheat tissues analyzed, and a protein, TaQM, was identified from a wheat root cDNA library, to(More)
BACKGROUND Heterosis in internode elongation and plant height are commonly observed in hybrid plants, and higher GAs contents were found to be correlated with the heterosis in plant height. However, the molecular basis for the increased internode elongation in hybrids is unknown. RESULTS In this study, heterosis in plant height was determined in two wheat(More)
In spite of commercial use of heterosis in agriculture, the molecular basis of heterosis is poorly understood. In this study, heterosis was estimated for eight root traits in 20 wheat hybrids derived from a NC Design II mating scheme. Positive mid-parent heterosis was detected in 96 of 160 hybrid-trait combinations, and positive high-parent heterosis was(More)
The Dof (DNA binding with one finger) proteins are plant specific transcription factors. Dof proteins are apparently encoded by a multiple gene family in higher plants. However, only one Dof gene, WPBF, was reported in wheat. In this study, a member of Dof gene family, TaDof1, was cloned from wheat. TaDof1 encode 291 amino acids, with a predicted molecular(More)
