Imaging mass spectrometry (IMS) is a powerful technique that enables analysis of various molecular species at high spatial resolution with low detection limits. In contrast to the matrix-assisted laser desorption/ionization (MALDI-MS) approach, surface-assisted (SALDI) can be more effective in small molecules due absence interfering background signals m/z ranges. We developed functionalized TiO...
drought is an important abiotic stress limiting plant performance. generation of reactive oxygen species (ros) is enhanced under stresses. two greenhouse experiments were conducted to evaluate the effect of phytohormones on the changes of antioxidant enzymes and carotenoids in petals of pot marigold (calendula officinalis l.) under drought stress. results showed that the activities of superoxid...
alstroemeria flower is one of the most important cut flowers in the world. some materials can increase longevity of cut flowers. the aim of this research was evaluating the effect of some chemical solutions on postharvest alstroemeria (cv. stratus) cut flowers. this experiment was conducted with two factors of sucrose at four concentrations, 0, 5, 10 and 15 g/l and salicylic acid (sa) at four c...
Catharanthus roseus or vinca produces over 130 TIAs with pharmaceutical value. Two of them, namely vinblastine (VB) and vincristine (VC), are species-specific and extensively used in anticancer chemotherapeutics. To detect C. roseus genotypes abundant in desired TIAs, contrasting genotypes should be analyzed via marker-assisted selection (MAS) to avoid analytical quantitation. A trustable morph...
The ranunculid genus Aquilegia holds extraordinary promise as a model system for investigating a wide range of questions relating to the evolution and ecology of petals. New genetic and genomic resources, including an extensive EST database, BAC libraries and physical maps, as well as virus-induced gene silencing are facilitating this research on multiple fronts. At the developmental genetic le...
To shorten the time required for breeding and optimize the risk-cost/benefit ratio of genetically modified ornamental plants, we applied heavy-ion beam irradiation to wild-type and genetically modified torenia (Torenia fournieri Lind. CV. ‘Crown Violet’ plants in which petal color and pattern had been modified by controlling two anthocyanin biosynthesis-related genes encoding chalcone synthase ...
BACKGROUND Roses have been cultivated for centuries and a number of varieties have been selected based on flower traits such as petal form, color, and number. Wild-type roses have five petals (simple flowers), whereas high numbers of petals (double flowers) are typical attributes of most of the cultivated roses. Here, we investigated the molecular mechanisms that could have been selected to con...
