Frozen buds
close-up, the flower buds of the weed Arabidopsis thaliana appear almost animal-like. The scanning electron micrographs above show a whole inflorescence (top right) and two individual flower buds in detail. The bud of a Columbia wild-type plant shown at bottom right has an oval shape and is tightly closed — as buds normally remain until the anther matures inside. By contrast, the bud on the lef...
متن کاملStaring at 4U 1909+07 with Suzaku
We present an analysis of the neutron star high mass X-ray binary (HMXB) 4U 1909+07 mainly based on Suzaku data. We extend the pulse period evolution, which behaves in a random-walk like manner, indicative of direct wind accretion. Studying the spectral properties of 4U 1909+07 between 0.5 to 90 keV we find that a power-law with an exponential cutoff can describe the data well, when additionall...
متن کاملBuilding limb buds
This workshop on limb development was a highly enjoyable meeting that covered a wide range of topics related to appendage development and evolution. The discussions were vivid, open and stimulating for all participants. It was particularly interesting to see how broadly accepted concepts, such as the morphogen models in the fly and the progress zone model in vertebrates, were re-evaluated on th...
متن کاملWhole-Transcriptome Analysis of Differentially Expressed Genes in the Vegetative Buds, Floral Buds and Buds of Chrysanthemum morifolium
BACKGROUND Chrysanthemum morifolium is an important floral crop that is cultivated worldwide. However, due to a lack of genomic resources, very little information is available concerning the molecular mechanisms of flower development in chrysanthemum. RESULTS The transcriptomes of chrysanthemum vegetative buds, floral buds and buds were sequenced using Illumina paired-end sequencing technolog...
متن کاملCellular mechanisms in taste buds.
In the soft palate, tongue, pharynx and larynx surrounding the oral region, taste buds are present, allowing the sensation of taste. On the tongue surface, 3 kinds of papillae are present: fungiform, foliate, and circumvallate. Approximately 5,000 taste buds cover the surface of the human tongue, with about 30% fungiform, 30% foliate and 40% circumvallate papillae. Each taste bud comprises 4 ki...
