In order to determine the reasons for pollen sterility in lily hybrids, four diploid sterile Oriental x Trumpet (OT) lily cultivars ('Nymph', 'Gluhwein', 'Yelloween', and 'Shocking') were used to investigate the meiotic chromosome behaviors in pollen mother cells (PMCs), using genomic in situ hybridization and conventional cytological methods. At metaphase I, chromosome associations were quite ...

BACKGROUND Depression is a chronic, recurring and potentially life-threatening illness. Current treatments for depression are characterized by a low success rate and associated with a wide variety of side effects. The aim of the present study was to evaluate the behavioral anti-depressant effect of a novel herbal compounds named ziziphi spinosae lily powder suspension, as well as to investigate...

Lily and Yuh Nung Jan's collaboration started with the identification of Shaker as the first known potassium channel gene and has flourished to produce over 100 former students and postdocs who are now leading their own research groups. In an interview with Neuron, they reflect on their scientific discoveries, serendipity in science, and the value of curiosity-driven basic research.

The Cover Feature shows the photo-driven conversion of CO2 as a water lily pond, where central role is given by new iron catalyst, here represented white lily. red flowers symbolize copper-based photosensitizers, which receive spotlight radiation. In their Research Article, C. Bizzarri and co-workers describe that photoinduced electron transfer processes are necessary to reduce able carbon diox...

In a recent article [4] the first two authors and R.L. Petersen have defined a notion of parametric LAPL-structure. Such structures are parametric models of the equational theory PILLY , a polymorphic intuitionistic / linear type theory with fixed points, in which one can reason using parametricity and, for example, solve a large class of domain equations [4,5]. Based on recent work by Simpson ...

Differences in level of herbivory can select for local adaptation and genetic differentiation of plant populations in different environments. Mean bulb depth of the desert lily Pancratium sickenbergeri, differs considerably among populations differing in the level of herbivory by the dorcas gazelle. The gazelle digs in the sand to remove most of the bulb of the lily. Deeper bulbs have less mate...

1. INTRODUCTION. The purpose of this article is to describe a computer game I created. I named the game " Lucy and Lily, " after my two daughters. If you want to play this game, you can find it on my website www.math.umd.edu/∼res. Some browsers have trouble with the game, but some work just fine. Many people have expressed enthusiasm for the game, and their enthusiasm has encouraged me to write...

gladiolus (gladiolus grandiflorus l.), a popular bulbous cut flower, has high demand in both domestic (pakistani) as well as international markets. five potential, exotic cultivars of gladiolus, ‘cantate’, ‘corveira’, ‘eminence’, ‘essential’ and ‘fado’ were evaluated to determine the cultivar effects on yield and quality, to compare their relative performance and recommend their suitability for...
