A certificate ownership varieties issued Center Crop Variety Protection and Agricultural Licensing, Ministry Agriculture Republic Indonesia very important to protect the illegal name meet requirements release varieties. The primary requirement get morpholog...

Flowers are vital for attracting pollinators to plants and in horticulture for humans. Petal morphogenesis is a central process of floral development. Petal development can be divided into three main processes: the establishment of organ identity in a concentric pattern, primordia initiation at fixed positions within a whorl, and morphogenesis, which includes petal elongation through the narrow...

We have analyzed expression from deletion derivatives of the 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) 5[prime]-upstream region in transgenic petunia flowers and seedlings. In seedlings, expression was strongest in root cortex cells and in trichomes. High-level expression in petals and in seedling roots was conferred by large (>500 base-pair) stretches of sequence, but was lost when s...

BACKGROUND The aim of this paper is to discuss the controversial origins of petals from tepals or stamens and the links between the morphological expression of petals and floral organ identity genes in the core eudicots. SCOPE I challenge the widely held classical view that petals are morphologically derived from stamens in the core eudicots, and sepals from tepals or bracts. Morphological da...

Although interspecific hybrids between cyclamen (Cyclamen persicum) cultivars and C. purpurascens were produced by using the ovule culture, mode of inheritance of flower pigment remains obscure. Therefore, inheritance of anthocyanin in the petals in the crosses between diploid cyclamen cultivars and C. purpurascens was investigated in the present study. In every cross combination, including the...

Japanese morning glory (Ipomoea nil) is a representative plant lacking a yellow-flowered cultivar, although a few wild Ipomoea species contain carotenoids in their petals such as Ipomoea sp. (yellow petals) and I. obscura (pale-yellow petals). In the present study, carotenoid composition and the expression patterns of carotenogenic genes during petal development were compared among I. nil, I. o...

Oilseed rape (Brassica napus L.), which has yellow flowers, is both an important oil crop and a traditional tourism resource in China, whereas the Orychophragmus violaceus, which has purple flowers, likely possesses a candidate gene or genes to alter the flower colour of oilseed rape. A previously established B. napus line has a particular pair of O. violaceus chromosomes (M4) and exhibits slig...

Abstract Objectives This study aimed to evaluate the functional activity and phytochemical composition in flower petals of Paeonia delavayi (P. delavayi) different colors. Materials Methods P. petal extracts were prepared by maceration methanol, including purple extract (PPE), red (RPE), yellow (YPE), their antioxidant α-glucosidase acetylcholinesterase inhibition activities evaluated. To corre...

Arabidopsis flowers have four petals. Other floral organs are not represented on the diagram. KLU expression in petals is shown in red. Wild-type tissue is shown in yellow whereas klu mutant tissue is shown in blue. Wild-type flowers are larger than klu mutant flowers. Flowers that contain wild-type and mutant tissue (chimeric flowers) are of intermediate size between wild-type and mutant flowe...

Leafless cut Superstar roses (Rosa hyb.) were kept in a 1% sucrose solution. During the first few days of treatment, the abscisic acid content and the water deficit in the petals was higher in treated flowers than in controls kept in water. Later and up to the termination of the flower's life, ABA content and water deficit values were lower in petals of sucrose-treated flowers than in controls....
