Pollen spares all but self

چکیده
Models based on the crystal structure of interleukin-1 vary significantly. D eP ri st o/ El se vi er UK) warns that, for any given structure in the Protein Data Bank (PDB), there will be many other overlooked structures that are equally consistent with the data. Crystallized proteins retain the ability to move around, thus making interpretations of diffraction data an imprecise process. Crystallographers fit their data to models that pass quality controls, but they usually report only one such model. The Cambridge group generated alternate models that fit the data for several proteins. “We found a reasonable number of structures that are surprisingly different in their finer details,” says

Self-incompatibility in the Iranian Almond Cultivar ‘Mamaei’ Using Pollen Tube Growth, Fruit Set and PCR Technique
Self-incompatibility has been studied by using controlled pollination, pollen tube growth and PCR methods in the Iranian almond ‘Mamaei.’. Pollen tube growth and fruit set following self and cross-pollination treatments were evaluated. The percentage of initial and final fruit set was determined for each treatment at 30 and 60 days after controlled pollination. Pollen germination and pollen ...

The present research was conducted with the purpose of studying self and cross-compatibility in some commercial cultivars of peach through field and microscopic studies in order to increase the quantity and quality traits of the product. The study was carried out in years 2010 and 2011. In a first experiment, the pollen germination of 10 cultivars of peach was studied in culture medium. The res...
متن کاملRight from the Start
Dr. Matthews has lectured to school children all over the country on the "facts of life". He spares us the bees and the pollen, and starts with how life began via the nucleus and pre-history. The plates and diagrams are clear and simple. He deals with the moral and spiritual significance of the sex relationship without sentimentality. He has not lost his own sense of wonder over the miracle of ...
متن کاملFour previously identified Petunia inflata S-locus F-box genes are involved in pollen specificity in self-incompatibility.
Dear Editor, Petunia possesses self-incompatibility (SI), by which pistils reject self-pollen but accept non-self pollen for fertilization (de Nettancourt, 2001; Iwano and Takayama, 2012). Genes that regulate self/non-self recognition between pollen and pistil are located at the highly polymorphic S-locus. An S-haplotype contains the pistil-specific S-RNase gene that regulates pistil specificit...
