Over the last decade, the yeast two-hybrid system has become the tool to use for the identification of protein-protein interactions and recently, even complete interactomes were elucidated by this method. Nevertheless, it is an artificial system that is sensitive to errors resulting in the identification of false-positive and false-negative interactions. In this study, plant MADS box transcript...
Rice contains several MADS box genes. It has been demonstrated previously that one of these genes, OsMADS1 (for Oryza sativa MADS box gene1), is expressed preferentially in flowers and causes early flowering when ectopically expressed in tobacco plants. In this study, we demonstrated that ectopic expression of OsMADS1 in rice also results in early flowering. To further investigate the role of O...
A simple statistical method for predicting the functional differentiation of duplicate genes was developed. This method is based on the premise that the extent of functional differentiation between duplicate genes is reflected in the difference in evolutionary rate because the functional change of genes is often caused by relaxation or intensification of functional constraints. With this idea i...
CRABS CLAW (CRC), a member of the YABBY gene family, is required for nectary and carpel development. To further understand CRC regulation in Arabidopsis thaliana, we performed phylogenetic footprinting analyses of 5' upstream regions of CRC orthologs from three Brassicaceae species, including Arabidopsis. Phylogenetic footprinting efficiently identified functionally important regulatory regions...
The plant MADS-box regulatory gene family includes several loci that control different aspects of inflorescence and floral development. Orthologs to the Arabidopsis thaliana MADS-box floral meristem genes APETALA1 and CAULIFLOWER and the floral organ identity genes APETALA3 and PISTILLATA were isolated from the congeneric species Arabidopsis lyrata. Analysis of these loci between these two Arab...
The shoot apical meristem (SAM), a small group of undifferentiated dividing cells, is responsible for the continuous growth of plants. Several genes have been identified that control the development and maintenance of the SAM. Among these, WUSCHEL (WUS) from Arabidopsis (Arabidopsis thaliana) is thought to be required for maintenance of a stem cell pool in the SAM. The MADS-box gene AGAMOUS, in...
The fruit canning industry processes large quantities of the clingstone varieties of peach (Prunus persica L. Batch). The occurrence of split-pit formation--the opening of the pit and sometimes splitting of the fruit--causes deterioration of canned fruit quality. The frequency of split-pit formation is influenced by genetic and environmental factors. To increase understanding of the molecular m...
Sundström, J., 2001. Evolution of genetic mechanisms regulating reproductive development in plants. Characterisation of MADS-box genes active during cone development in Norway spruce. Acta Univ.Ups., Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 612. 44 pp. Uppsala. ISBN 91-554-4969-7. The reproductive organs of conifers and angiosperms differ in mo...
The Arabidopsis MADS domain proteins API, AP3, PI, andAG specify floral organ identity. All of these proteins contain a MADS domain required for DNA binding and dimerization; a region termed L (linker between MADS domain and K domain), which plays an important role in dimerization specificity; the K domain, named for its similarity to the coiled-coil domain of keratin; and a C-terminal region o...
