—In the Shadow of Young Girls in Flower by Marcel Proust P because chrysanthemums bloom well into the autumn and come in an array of colors and varieties, these hardy flowers have inspired poets, writers, and artists for millennia. French Impressionist artist Claude Monet celebrated this flower in a series of four still-life paintings in 1897, including Chrysanthemum, 1897, selected for this mo...

Autoradiography with Ca(45) has been used to obtain information about the relation between calcium and chromosomes. Labelled pollen from the Easter lily, Lilium longiflorum, was allowed to develop into pollen tubes between 5 and 6 cm. long in the styles of non-radioactive flowers. All of the nuclei, namely the tube nucleus and the two sperm nuclei, retain Ca(45) after this period of growth and ...

Normalization to reference genes is the most common method to avoid bias in real-time quantitative PCR (qPCR), which has been widely used for quantification of gene expression. Despite several studies on gene expression, Lilium, and particularly L. regale, has not been fully investigated regarding the evaluation of reference genes suitable for normalization. In this study, nine putative referen...

Anthocyanins are secondary metabolites that contribute to colors of flowers, fruits and leaves. Asiatic hybrid lily (Lilium spp.) accumulates cyanidin anthocyanins in flower tepals, tepal spots and leaves of juvenile shoots. To clarify their mechanisms of regulation of anthocyanin pigmentation, two full-length cDNAs of R2R3-MYB (LhMYB6 and LhMYB12) were isolated from the anthocyanin-accumulatin...

Lily (Lilium formosanum or Lilium longiflorum) pollen tubes, microinjected with a low concentration of the pH-sensitive dye bis-carboxyethyl carboxyfluorescein dextran, show oscillating pH changes in their apical domain relative to growth. An increase in pH in the apex precedes the fastest growth velocities, whereas a decline follows growth, suggesting a possible relationship between alkalinity...

Morphological parameters and RAPD (Random amplified polymorphic DNA) markers have been used to evaluate the effect of gamma radiation on different varieties of Lilium plant. In vivo treated plants were studied to observe the alternations in growth parameters.Change in plant morphology in aspect of flower morphology (flower colour and shape), leaf length, leaf width, shoot length and number of l...

We examined exocytosis during oscillatory growth in lily (Lilium formosanum and Lilium longiflorum) and tobacco (Nicotiana tabacum) pollen tubes using three markers: (1) changes in cell wall thickness by Nomarski differential interference contrast (DIC), (2) changes in apical cell wall fluorescence in cells stained with propidium iodide (PI), and (3) changes in apical wall fluorescence in cells...

Lily (Lilium spp), which belongs to Lilium, is one kind of monocotyledon. As a perennial ornamental plant with extremely high esthetic, edible, and medicinal value, lily has gained much favor due to its mostly showy flowers of various colors and elegant shape. In this research, we studied experimental materials in a sample of 49 individuals including 40 cultivars, nine species of wild lily, and...
