structure of the flower and the fruit of Petagnaea, and the possible implications for its breeding system and seed dispersal mechanism.Results from fieldwork, light microscopy and scanning electron microscopy suggest (1) the presence of protandrous hermaphrodite flowers; (2) geitonogamy, autogamy,...
Flower and pollen structure is described in Dana , Ruscus and Semele (Ruscaceae) and Aspidistra , Tupistra and Rohdea (Convallariaceae- Aspidistreae) in order to assess a possible relationship between them. Ovules are crassinucellate in Dana , Ruscus and Semele . Pollen is monosulcate in ...

In this Paper, the author has discussed the flower structure of the bracts and Perianth of Basella Family (Basellaceae) which has been for long time in confusion. It is based on my own observation that the following description is more near to the fact, "bracts 3, bracteoles 2, sepals...
The Arabidopsis homologs of trithorax (ATX1) and enhancer of zeste (CLF) establish 'bivalent chromatin marks' at the silent AGAMOUS locus. Arabidopsis homolog of enhancer of zeste (EZ) and the ARABIDOPSIS HOMOLOG OF TRITHORAX (ATX1) control the expression of the flower homeotic gene AGAMOUS .....
The past few years have witnessed a veritable explosion in the development of new methods for the isolation and structure determination of natural products. This is true in particular for the applications of novel separation technologies and modern spect
sunflower patches in the landscape neighbourhood will have a scale-dependent effect. We found that an increasing area and/or dispersion of hSNH areas enhanced the visitation of all pollinator groups. These positive effects were scale-dependent and corresponded well with the foraging ranges of the ...
