Four full-length MADS-box cDNAs from chrysanthemum, designated Chrysanthemum Dendrathema grandiflorum MADS (CDM) 8, CDM41, CDM111, and CDM44, have been isolated and further functionally characterized. Protein sequence alignment and expression patterns of the corresponding genes suggest that CDM8 and CDM41 belong to the FRUITFULL (FUL) clade, CDM111...
Resource use and phylogeny are often correlated with morphological variation. Moreover, because biological shapes are often complex and evolve depending on several internal constraints, they must be assessed using integrative methods.We analyzed the morphological variation of the turtle skull in the context of an adaptive radiation. Our focus are t...

Micron-sized internal cracks were introduced into rounded bars of pure iron by low cycle fatigue, and the cracks had irregular penny-shaped morphology with the critical diameter of about 30μm and the thickness of 0.5–1.5μm. The initiation and propagation of the cracks were investigated quantitatively as well as their location and geometry. After va...

Sequences of the ITS region of nrDNA were analyzed for the seven genera of Papaveraceae subf. Chelidonioideae s.str. Three major clades can be recognized. These are 1.Chelidonium/Hylomecon/Stylophorum, 2.Eomecon/Sanguinaria, and 3.Bocconia/Macleaya. The monophyly of genera in the first of these three clades is doubtful, and clades two and three are...

Molecular methods are used widely to measure genetic diversity within populations and determine relationships among species. However, it is difficult to observe genomic evolution in action because these dynamics are too slow in most organisms. To overcome this limitation, we sampled genomes from populations of Escherichia coli evolving in the labor...

The sibling species Drosophila simulans and D. mauritiana differ significantly in a number of male secondary sexual traits, providing an ideal system for genetic analysis of interspecific morphological divergence. In the experiment reported here, F1 hybrids from a cross of two inbred lines were backcrossed in both directions and about 200 flies fro...
