Compatible and incompatible pollen tubes growing on detached Lilium longiflorum pistils which had been prelabeled with myoinositol-U-(14)C take up a portion of the label and utilize it for biosynthesis of tube wall substance. The label is transferred from pistil to pollen tubes apparently via the secretion products (exudate) of the pistil. The exudate thus appears to have a major nutritional ro...

The effects of different concentrations of Zinc oxide nano particles (ZnONP; 0, 10, 25, 50, 75 and 100 mg L-1) and Humic acid (HA; 0, 50, 100, 500 and 1000 mg L-1) on root length and number, leaf length and number, bulb diameter, and chlorophyll, total phenol, anthocyanin and flavonoid contents were examined under in vitro conditions. Total phenol, flavonoid and anthocyanin contents were signif...

Lilium brownii var. colchesteri has been widely cultivated for long time by its perfect flower shape with its colour arrangement and fragrance. However, it did not receive enough attention in recent lily research programs, and information on the history and culture is lacking. An overall research project on this species including breeding, flowering control, propagation, virus-free bulb product...

The multiplication efficacy by bulb is low and the plantlets are more susceptible to disease, therefore, there a need develop protocol for its propagation. Lilium candidum listed in saitma prefecture Red Data Book as critically endangered plant rescuing information regarding micro-propagation rather limited. On this regard, application of vitro micropropagtion procedure might help obtain large ...

Little is known about geographic variation in the local composition of South American assemblages of mammals or the factors that may produce such variation. This is particularly unfortunate in Paraguay because it occurs at the interface of a number of phytogeographic regions (e.g., Cerrado, Chaco, Interior Atlantic Rainforest, and Pantanal) and is the point at which many temperate species reach...

An analysis of duplicate phytochrome genes (PHYA and PHYC) is used to root the angiosperms, thereby avoiding the inclusion of highly diverged outgroup sequences. The results unambiguously place the root near Amborella (one species, New Caledonia) and resolve water lilies (Nymphaeales, approximately 70 species, cosmopolitan), followed by Austrobaileya (one species, Australia), as early branches....

Microspores isolated from Lilium longiflorum and Trillium erectum were studied with respect to their capacities for phosphorylating deoxyribosides in vitro. It was found that such capacities are manifest only during brief intervals of time adjacent to periods of DNA synthesis, and that none of the neighboring cells in the anther acquire them. The observed patterns of behavior are interpreted in...

saliva (slv) transcription begins at the salivary gland placodes and continues on throughout development as salivary glands invaginate and reach their final location and morphology. saliva is located cytogenetically in 76A/B, and encodes a 226-amino-acid protein with four hydrophobic domains. A Northern blot detects a 1.6-kb transcript throughout development. Database similarity searches reveal...
