We isolated a rice T-DNA tagging line, in which T-DNA was inserted into the sixth intron of OsP5CS2. This gene encodes for a protein that is highly homologous to 1-pyrroline-5-carboxylate synthetase (P5CS), a proline biosynthesis enzyme. The T-DNA contained the promoterless gus gene, allowing generation of a gene fusion between OsP5CS2 and gus. Therefore, the expression pattern of OsP5CS2 could...

Plants combining the cytoplasm of Nicotiana debneyi and the 48 chromosomes from N. tabacum are male sterile. Early backcross generations of the amphidiploid hybrid to male N. tabacum produced a great variety of plants from which a series of phenotypes with characteristic flower forms and transmission rates have been isolated. Type 1A possesses completely feminized stamens and deeply split corol...

We present a simple and effective modeling method for flowers. It starts with an initial geometric shape, such as ellipsoid, cylinder, or plane surface et al., and then simulates flower components (such as pedicel, receptacle, pistils, stamens, petals and sepals) by addition deformation to the basic geometric shape. The detailed geometry of flower component is defined by basic equation for the ...

Summary Clusia falcata (Clusiaceae), a new species from Chiapas, Mexico, is described and illustrated. This taxon distinctive for its leaves, among the narrowest of all known species, having lanceolate to oblong laminas that are mostly 10 – 15 × 2 2.5 cm. The flowers have quadrangular perianth with succulent petals, non-resiniferous androecium gynoecium. Staminate androphore bearing 18 24 short...

Four species from Liliaceae family were studied: Bellevalia glauca (Lindl.) Kunth., kurdistanica Feinbrum, Gagea reticulata Salisb. and Ornithogalum brachystachys C.Koch, morphologically anatomically. Plants collected Gurfa-Adhim district between March May, 2016. Bulb, scape, stem leaves, inflorescence flowers examined variations in size, shape dimensions recorded. The results revealed close mo...

Basal asterid families, and to a lesser extent the asterids as a whole, are characterized by a high variation in petal and stamen morphology. Moreover, the stamen number, the adnation of stamens to petals, and the degree of sympetaly vary considerably among basal asterid taxa. The B group genes, members of the APETALA3 (AP3) and PISTILLATA (PI) gene lineages, have been shown to specify petal an...

Salvia alata is reported as new record for Ecuador. This species belongs to S. sect. Macrostachyae, thus an updated identification key of this section provided. The descriptions and the most morphologically similar it (Salvia speciosa) are complemented with information photographs taken in field. distributed Ecuador Peru can be distinguished from speciosa by its pilose vegetative organs, flower...
