The effect of the complex relationship between ethylene and abscisic acid (ABA) on flower development and senescence in Hibiscus rosa-sinensis L. was investigated. Ethylene biosynthetic (HrsACS and HrsACO) and receptor (HrsETR and HrsERS) genes were isolated and their expression evaluated in three different floral tissues (petals, style-stigma plus stamens, and ovaries) of detached buds and ope...

We describe allelic series for three loci, mutations in which result in homeotic conversions in two adjacent whorls in the Arabidopsis thaliana flower. Both the structure of the mature flower and its development from the initial primordium are described by scanning electron microscopy. New mutations at the APETALA2 locus, ap2-2, ap2-8 and ap2-9, cause homeotic conversions in the outer two whorl...

The evolution of dioecy from hermaphroditism allows for avoidance self-pollination, and its evolutionary background has been investigated both experimentally theoretically since it was first proposed by Darwin. To reproduce this evolution, we screened hermaphroditic mutants Silene latifolia using heavy-ion beam or γ-ray irradiation characterized the phenotypes their floral organs. Our scatterpl...

Butterfly pea (Clitoria ternatea L.) is an important perennial herbaceous plant with a range of uses as ornamental plants, fodder crops, medicine, and sources natural food colorant antioxidants. The leaves pods are commonly used source protein in fodder, while the flowers usually dried processed high antioxidant-containing tea. blue variant butterfly was most variety, although there quite diver...

Based on ongoing ecological research in mountain forests of Sulawesi, a new species, Elaeocarpus firdausii Brambach, Coode, Biagioni & Culmsee, sp. nov. is described and illustrated from mossy forests at > 2000 m and information provided on the species' distribution, ecology and pollen morphology. Elaeocarpus firdausii is similar to Elaeocarpus luteolignum Coode but differs from the latter in h...

Nesogordonia tricarpellata Skema & Dorr, sp. nov., a new species from southeastern Madagascar, is described and illustrated. It differs from all other species of Nesogordonia Baill. in having 6-9 stamens, 3 staminodes, a 3-carpellate ovary, and a 3-valved capsule. These androecial and gynoecial characters require modification of the long-standing circumscription of the genus. The new species al...

Saffron spices are composed of dehydrated stigmas Crocus sativus L. A large amount bio-residues (stamens, tepals, and stigmas) is generated during the production this spice (~92 g per 100 flowers). These usually discarded losing chance to obtain interesting bioactive compounds from them. In work, we use saffron as possible source natural compounds. Different extraction conditions were applied o...

Abstract. Normasiwi S, Salamah A, Surya MI. 2021. Morphological characteristics of Indonesian Rubus flowers. Biodiversitas 22: 1441-1447. spp. are woody or herbaceous plants that can be used for fruit, ornamental and medicinal purposes. The increasing use as a commercial species is highly dependent on the formation high-quality genetic material. However, lack basic biological knowledge one limi...
