The most part of hibiscus plants produces short life flowers that last one day. Therefore they are called ephemeral and flower senescence is usually associated with petal in-rolling and abscission. Flowers are well shaped and different organs can be easily separated, these characteristics make the hibiscus a good model system for flower senescence studies. The aim of this work was to identify m...

RNA interference (RNAi) is an efficient and powerful technique for gene silencing compared with antisense and sense suppression. Here we report adaptation of RNAi technology to modify flower colors in gentian, targeted for suppression of three anthocyanin biosynthetic genes; chalcone synthase (CHS), anthocyanidin synthase (ANS) and flavonoid 3 ,5 -hydroxylase (F3 5 H). The petals of transgenic ...

The large number of publications in the field of extraction, purification, modification, and process optimization of natural dyes and their application on textiles demonstrates the revival of natural dyes on textile coloration. The use of natural dyes is growing in popularity because of the quality of the natural dyestuff obtained, the environmental compatibility of the dyes and the substantial...

The reproductive performance of plants depends on the temperature of the flower. A recent study reports the mechanistic basis of flower head orientation in sunflowers and provides intriguing hints as to its functional significance.

Minimally invasive investigation of plant parts (root, stem, leaves, and flower) has good potential to elucidate the dynamics of plant growth, morphology, physiology, and root-rhizosphere interactions. Laboratory based absorption X-ray imaging and computed tomography (CT) systems are extensively used for in situ feasibility studies of plants grown in natural and artificial soil. These technique...

Flower strips are commonly recommended to boost biodiversity and multiple ecosystem services (e.g., pollination and pest control) on farmland. However, significant knowledge gaps remain regards the extent to which they deliver on these aims. Here, we tested the efficacy of flower strips that targeted different subsets of beneficial arthropods (pollinators and natural enemies) and their ecosyste...

lehmannia valentiana is one of the most important pests of ornamental plants, vegetables and other agricultural crops, which causes noticable damages. in a food experiment four kinds of food for 24 and 72 hours were offered. the preferences of food were amaranthus tricolor, cineraria grandiflora, pelargonium peltatum, rosa damascena and l. valentiana. the l. valentiaiia is active the whole year...
