In flowering plants, the founder cells from which reproductive organs form reside in structures called floral meristems. Recent molecular genetic studies have revealed that the specification of floral meristems is tightly controlled by regulatory networks that underpin several coordinated programmes, from the integration of flowering signals to floral organ formation. A notable feature of certa...

when thinking about traditional iranian architecture, one imagines extensive ornamental patterns that adorn almost every surface of mosques and other prominent buildings. yet, many theories of architecture since the beginning of twentieth century have considered ornamentation a superficial and superfluous layer. but, are these ornamental surfaces superficial and can they be removed so easily? t...

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...

The purpose of this study was to investigate online learning service management (ORNAMENT) for student activeness by using the Rasch model analysis. research method used is mixed method. Samples were three public junior high schools (PJHS) in Bandung, West Java, Indonesia. data source are 58, consisting 19 PJHS X (high quality), Y (medium quality) and 20 Z (low quality). For quantitative data, ...

Abstract This study deals with folkloric research object within Germanic and Russian Formalism, it shows why folklore ornament have become an ideal of the European formalist current in Slavic areas.

The article describes two tombstones of the XIV century. in form high trapezoidal stone slabs (the lower end is narrower than upper part) from largest artistic center Dagestan - village Kubachi. They are located medieval Muslim cemetery "Bidakh Khuppe" (in lane with Kubach "Cemeteries on other side"), 1.5-2 km south old part Kubacha, half northern slope Mount Tsitsila. monuments under considera...

1. Maternal investment in egg quality can have important consequences for offspring fitness. For example, yolk antioxidants can affect embryonic development as well as juvenile and adult phenotype. Thus, females may be selected to advertise their yolk antioxidant deposition to discriminatory males via ornamental signals, perhaps depending on the reproductive costs associated with signal product...

Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Science and Technology 1076. 43 pp. Uppsala. ISBN 978-91-554-8758-4. Mate choice plays an important role in sexual selection and speciation. The evolution of mate choice is intriguing in cases where cho...

The evolutionary divergence of sexual signals is often important during the formation of new animal species, but our understanding of the origin of signal diversity is limited [1, 2]. Sensory drive, the optimization of communication signal efficiency through matching to the local environment, has been highlighted as a potential promoter of diversification and speciation [3]. The swordtail chara...
