A screen for mutations affecting flower formation was carried out and several filamentous flower (fil) alleles were identified. In fil mutants, floral primordia occasionally give rise to pedicels lacking flowers at their ends. This defect is dramatically enhanced in fil rev double mutants, in which every floral primordium produces a flowerless pedicel. These data suggest that the FIL and REV ge...

This research examines a chronic problem in academic settings – inappropriate copying or misuse of source materials–i.e., plagiarism. We conduct a computer-based writing experiment to examine the effects of psychological and situational characteristics on subjects’ propensity to misappropriate text. Specifically, we examine to what extent such misappropriations may be explained by available tec...

Using 3.3 pb of data collected with the CMD-2 detector in the 720 – 840 MeV c.m. energy range, the branching fraction of the conversion decay ω → πee has been measured: B(ω → πee) = (8.19 ± 0.71± 0.62) · 10. The upper limits for the branching fractions of the following conversion decays have been obtained at the 90% confidence level: B(ρ → πee) < 1.6 · 10, B(ρ → ηee) < 0.7 · 10 and B(ω → ηee) <...

This study identifies the uniqueness of climbing floral themes used on Terengganu batik sarongs. Digital image compilation and motif tracing sarong were to examine climber characters. The relevant literature was mapped onto motifs linked elements’ function role. examination revealed that flower designs at apit kain (framing border) tepi (upper lower edge parts). Various types tropical flowers d...

In the last two decades the genetic and molecular research on floral development has advanced tremendously. Initially the research focused mostly on the two species of which the homeotic floral development mutants formed the basis for the ABC‐model: Arabidopsis and Antirrhinum. In recent years the importance of studying a wider range of species, especially in an ‘‘evo‐devo’’ context, has become...

Insects use several senses to forage, detecting floral cues such as color, shape, pattern, and volatiles. We report a formerly unappreciated sensory modality in bumblebees (Bombus terrestris), detection of floral electric fields. These fields act as floral cues, which are affected by the visit of naturally charged bees. Like visual cues, floral electric fields exhibit variations in pattern and ...

Using a discourse analytic qualitative approach, we investigated the naturally-occurring discourse that arose as part of two kinds of regular course activities, synchronous and asynchronous computer-mediated discussions. The messages contributed by members of a graduate course were analyzed for the kind of discourse functions and the kind of politeness strategies they displayed. Results indicat...

Polymorphism of floral signals, such as colour and odour, is widespread in flowering plants and often considered to be adaptive, reflecting various pollinator preferences for particular floral traits. Several authors have recently hypothesized that particular associations exist between floral colour and scent, which would result from shared biochemistry between these two floral traits. In this ...

Although many genes that regulate floral development have been identified in Arabidopsis thaliana, relatively few are known in the grasses. In normal maize (Zea mays), each spikelet produces an upper and lower floral meristem, which initiate floral organs in a defined phyllotaxy before being consumed in the production of an ovule. The bearded-ear (bde) mutation affects floral development differ...
