Gibberellic acid (GA(3)) sensitivity (measured as alpha-amylase production) of the isolated aleurone tissue/deembryonated seed of two wheat (Triticum aestivum L. var Kite and var Aroona) varieties each containing either one of the dwarfing genes, Rht1 and Rht2, was increased significantly as a result of low temperature treatment. The magnitude of the low temperature-induced increase occurred wi...
Activating mutations in the genes for fibroblast growth factor receptors 1-3 (FGFR1-3) are responsible for a diverse group of skeletal disorders. In general, mutations in FGFR1 and FGFR2 cause the majority of syndromes involving craniosynostosis, whereas the dwarfing syndromes are largely associated with FGFR3 mutations. Osteoglophonic dysplasia (OD) is a "crossover" disorder that has skeletal ...
Elucidating factors associated with diversification have been attempted in lineages as diverse as birds, mammals and angiosperms, yet has met with limited success. In flowering plants, the ambiguity of associations between traits and diversification has sparked debate since Darwin's description of angiosperm diversification as an 'abominable mystery'. Recent work has found that diversification ...
Halophilic archaebacteria (Haloarchaea) can survive extreme desiccation, starvation and radiation, sometimes apparently for millions of years. Several of the strategies that are involved appear specific for Haloarchaea (for example, the formation of halomucin, survival in fluid inclusions of halite), and some are known from other prokaryotes (dwarfing of cells, reduction of ATP). Several newly-...
We have used activation tagging with T-DNA carrying cauliflower mosaic virus 35S enhancers to investigate the complex signaling networks underlying disease resistance in Arabidopsis. From a screen of approximately 5000 lines, we identified constitutive disease resistance (CDR1) encoding an apoplastic aspartic protease, the overexpression of which causes dwarfing and resistance to virulent Pseud...
