An adaptive role of corolla shape has been often asserted without an empirical demonstration of how natural selection acts on this trait. In generalist plants, in which flowers are visited by diverse pollinator fauna that commonly vary spatially, detecting pollinator-mediated selection on corolla shape is even more difficult. In this study, we explore the mechanisms promoting selection on corol...

Ethylene plays an important role in organ growth. In Arabidopsis, ethylene can inhibit root elongation by stabilizing DELLA proteins. In previous work, it was found that ethylene suppressed cell expansion in rose petals, and five unisequences of DELLA genes are induced by ethylene. However, the mechanism of transcriptional regulation of DELLA genes by ethylene is still not clear. The results sh...

Flowering peach Prunus persica cv. Genpei bears pink and variegated flowers on a single tree. The structural genes involved in anthocyanin biosynthesis were expressed strongly in pink petals but only very weakly or not at all in variegated petals. A cDNA clone encoding a MYB-like gene, isolated from pink petals was strongly expressed only in pink petals. Introduction of this gene, via biolistic...

Edelweiss is a plant that grows at height, and known as perennial flower because it has beautiful petals does not wilt easily. Although edelweiss in Indonesia still the same family Leontopodium Alpinum, turns out type of found mountains different from abroad. Therefore, this study, an image processing system was developed can classify types flowers based on their using Linear Discriminant Analy...

This study investigated genetic polymorphism related to anthocyanin composition variation in lisianthus (Eustoma grandiflorum) flower petals. Three different bands were detected by genomic polymerase chain reaction using specific primers based on the reported flavonoid 3',5'-hydroxylase (F3'5'H) gene sequence. Our revealed that they allelic. They named F3'5'H1-1, F3'5'H1-2, and f3'5'h1-2. F3'5'...

Flowers are very diverse, with a large range in the size, number, color and morphology of the floral organs, differences that seem to reflect the adaptation of individual species to their mechanism of pollination. The study of the genetic basis of the generation of flower form has been greatly aided by a handful of model plant species, including Antirrhinum (Snapdragon), Arabidopsis and Petunia...
