The influence of bulb maturity at bulb harvest on growth and flowering response of Ornithogalum thyrsoides Jacq. ‘Chesapeake Starlight’ was investigated. Experiments were designed to determine if bulb maturity can be induced by bulb storage temperatures and whether bulb maturity can be evaluated by flowering responses. Bulbs with all senesced leaves at harvest were considered ‘‘mature’’ or with...

Although flowering regulatory mechanisms have been extensively studied in Arabidopsis (Arabidopsis thaliana), those in other species have not been well elucidated. Here, we investigated the role of OsMADS51, a type I MADS-box gene in the short-day (SD) promotion pathway in rice (Oryza sativa). In SDs OsMADS51 null mutants flowered 2 weeks later than normal, whereas in long days loss of OsMADS51...

Diazinon is an organophosphate which exerts tissue damages by generating free radicals thereby inducing oxidative stress. The purpose of this study is to determine the protective effect of Salvia officinalis L.extract on testes of rats intoxicated by diazinon. In this experimental study, 45 mature male rats were equally divided into three groups of Control (C), Diazinon (DZN) and Diazinon-Extra...

In 1961 George Mackey introduced the concept of a virtual group as an equivalence class under similarity of ergodic measured groupoids, and he developed this circle of ideas in subsequent papers in 1963 and 1966. The goal here is first to explain these ideas, place them in a larger context, and then to show how they have influenced and helped to shape developments in four different but related ...

A 7-month-old girl developed fever, unconsciousness, and left oral clonic seizures. EEG showed background slowing and periodic lateralized epileptiform discharges (PLED) over right central-temporal regions. Brain MRI revealed a right temporal pole T2 hyperintense lesion (figure 1). CSF PCR was positive for herpes simplex virus 1. Five days after starting treatment with acyclovir (45 mg/kg/day) ...

Legumes are commonly grown in the tropics under reduced solar radiation due to dense cloud cover and shading from plantation or tall intercrops. This paper examines the growth and N2 fixation of several grain legumes common to the tropics on an Oxic Haplustoll in Hawaii. Plantings were made in April (warm season) and November (cool season) of soybean (Glycine max L. Merr.) ‘Kahala’; Cowpea (Vig...

Arabidopsis flowers in long day (LD) in response to signals transported from the photoinduced leaf to the shoot apex. These LD signals may include protein of the gene FLOWERING LOCUS T (FT) while in short day (SD) with its slower flowering, signalling may involve sucrose and gibberellin. Here, it is shown that after 5 weeks growth in SD, a single LD up-regulated leaf blade expression of FT and ...

BACKGROUND AND AIMS Flowering phenology is a potentially important component of success of alien species, since elevated fecundity may enhance invasiveness. The flowering patterns of invasive alien plant species and related natives were studied in three regions with Mediterranean-type climate: California, Spain and South Africa's Cape region. METHODS A total of 227 invasive-native pairs were ...
