Recent electron microscope studies of nuclei and chromosomes have shown that a microfibril from 100 to 200 A thick is the basic morphological unit of chromosomes. Chromosome fibrils of this dimension have been reported in the salivary gland chromosomes of Drosophila ~irilis (20, 21), in salivary chromosomes of D. melanogaster (9), in leptotene, pachytene, and metaphase chromosomes of Lilium (13...

It is well known that a tip-focused intracellular Ca2+ gradient and the meshwork of short actin filaments at the tip region are necessary for pollen tube growth. However, little is known about the connections between the two factors. Here, a novel Ca2+-dependent actin-binding protein with molecular mass of 41 kD from lily (Lilium davidii) pollen (LdABP41) was isolated and purified with DNase I ...

Lilies (Lilium sp.) are commercially important horticultural crops widely cultivated for their flowers and bulbs. Here, we conducted large-scale data mining of the lily transcriptome to develop transcription factor (TF)-associated microsatellite markers (TFSSRs). Among 216,768 unigenes extracted from our sequence data, 6966 unigenes harbored simple sequence repeats (SSRs). Seventy-one SSRs were...

Self-incompatibility in Lilium longiflorum cv. Hinomoto diminishes with aging of the flower. The relation between the diminished self-incompatibility of the aged flower and stylar canal exudate in Lilium longiflorum was studied. Carbohydrate content in stylar canal exudate increased with aging of the flower, indicating that it accumulated with time. During the aging process, the molecular weigh...

Lily (Lilium) is used as an important edible and medical plant species with a vague taxonomic classification and a long history in China. Bulbs of six Lilium species (L. regale, L. concolor, L. pumilum, L. leucanthum, L. davidii var. unicolor and L. lancifolium) native to China were investigated with a view to their exploitation as a potential source of natural antioxidants due to their phenoli...

David Smyth is a plant developmental geneticist. He began his independent career at Monash University in Melbourne in 1974, where he investigated the basis of the very large genomes of the true lilies (Lilium species) when DNA cloning methods became available. Two abundant dispersed elements turned out to be retrotransposons, revealing their important role in bulking up some plant genomes. In 1...

Most recent phylogenetic analyses of basal angiosperms have converged on the placement of Amborella as sister to all other extant angiosperms. However, certain recent studies suggest that Amborella and Nymphaeales (water lilies) form a clade sister to all remaining angiosperms or that Nymphaeales alone are the sister to the remaining angiosperms. We report here (i) maximum parsimony, maximum li...

— We construct examples of simply connected nonalgebraic symplectic fourfolds with a prescribed number of nonintersecting symplectic curves with positive self-intersections.

Hybrid lilies are excellent cut flowers due to the availability of flowers with various colors and shapes. Extensive inter-species hybridization has resulted in numerous cultivars, and many new cultivars are introduced to the market each year. While the vigor and reliability of the crop has improved over the years, what has not changed is that the postharvest quality of the cut stem is an impor...
