Abstract A sweet fruit taste of passion is produced by Passiflora ligularis , which adapts in around 1400 masl. Some P. edulis accessions wide elevation adaptation was reported to have a taste. This study aimed examine the morphological characteristics progenies from red- and yellow-rind obtain an adaptive accession low-elevation conditions. total 118 classified as their parents’ rind color sha...

Description A perennial herb with a subterranean, digitately branched rhizome producing stems up to 1.50 m in height with linear lanceolate sheating leaves (5-30 cm long and 8-20 mm wide) that are alternate, smooth and pale green. Flower stems shorter than leaf stems and bearing a few flowers, each surrounded by a thin bract and situated in axils of large greenish yellow obtuse bracts, which ar...

A fundamental goal in evolutionary biology is to identify the molecular changes responsible for adaptive evolution. In this study, we describe a genetic analysis to determine whether the molecular changes contributing to adaptive flower color divergence in Mimulus aurantiacus affect gene expression or enzymatic activity. High performance liquid chromatography analysis confirms that flower color...

Biologists have long assumed that pollinator behavior is an important force in angiosperm speciation, yet there is surprisingly little direct evidence that floral preferences in pollinators can drive floral divergence and the evolution of reproductive (ethological) isolation between incipient plant species. In this study, we expose computer-generated plant populations with a wide variation in f...

In this paper, synthesis of the flower-like zinc oxide was performed using microwave assisted dicationic ionic liquid [mmp(im)2 ]Br2 . The polycrystalline flower-like zinc oxide nanostructure was obtained when a suitable mole ratio (ionic liquid /zinc acetate) and short duration microwave was used. X-ray diffraction (XRD), scanning electron microscopy (SEM), and photoluminescence (PL) spectra w...

Pickerelweed (Pontederia cordata L.) is a diploid (2n = 2x = 16), erect, emergent, herbaceous aquatic perennial. The showy inflorescences of pickerelweed make this species a prime candidate for inclusion in water gardens and aquascapes. The objective of this experiment was to determine the number of loci, number of alleles, and gene action controlling flower color (blue vs. white) in pickerelwe...

Scarlet rosemallow (Hibiscus coccineus Walter) is a diploid, perennial, erect, and woody shrub. The species is a desirable inclusion in home landscapes because it is a native plant with attractive flowers and unusual foliage. The objective of these experiments was to determine the number of loci, number of alleles, and gene action controlling flower color (red vs. white) in scarlet rosemallow. ...

In a natural environment, humans are not able to process all information available to the visual system simultaneously. As a consequence, we attend to different subparts of the input one after the other. Under natural viewing conditions, these shifts of attention are associated with changes in fixation. This so-called “overt” attention therefore provides an objective measure of attention shifts...

Geographical variation in flower color of a plant species may reflect the outcome selection by pollinators or abiotic factors such as soil chemistry neutral processes genetic drift. Here we document striking geographical structure capitula endemic South African grassland daisy Gerbera aurantiaca and ask which these competing explanations best explains this pattern. The ranges from predominantly...
