Plasma membranes are dynamic compartments with key functions in solute transport, cell shape, and communication between cells and the environment. In mammalian cells and yeast, the plasma membrane has been shown to be compartmented into so-called lipid rafts, which are defined by their resistance to treatment with non-ionic detergents. In plants, the existence of lipid rafts has been postulated...

This paper describes the participation of Inria within the Pl@ntNet project at the LifeCLEF2014 plant identification task. The aim of the task was to produce a list of relevant species for each plant observation in a test dataset according to a training dataset. Each plant observation contains several annotated pictures with organ/view tags: Flower, Leaf, Fruit, Stem, Branch, Entire, Scan (excl...

Synthesis of widespread types of nanoparticles including metal oxides by plant extract is considered as alternative chemical synthesis methods. ZnO nanoparticles are synthesized by a biological process using flaxseeds (Linum usitatissimum L.) extract. The biosynthesized ZnO NPs were characterized by XRD and SEM, EDX, DLS spectroscopy. According to the SEM images, the synthesized nanopa...

plant cell cultures could be used as an important tool for biochemical production, ranging from natural pigments to pharmaceutical products. anthocyanin is affected by a variety of factors. light, an important plant environmental factor, influences the anthocyanin production in vegetative plant tissues. here, we have investigated the influence of the blue laser-diode (bld) and red laser-he ne (...

The striped stemborer (SSB), Chilo suppressalis Walker, 1863 is a widely distributed pest of the rice agroecosystem. It bores and feeds inside the stalks of the rice plant during larval stage using its strong mandibles. Host-plant resistance has played a very important role in the management of this pest however; many cultivated types have succumbed to infestation even those with hard stems. Si...

The paleohexaploid crop Brassica rapa harbors an enormous reservoir of morphological variation, encompassing leafy vegetables, vegetable and fodder turnips (Brassica rapa, ssp. campestris), and oil crops, with different crops having very different leaf morphologies. In the triplicated B. rapa genome, many genes have multiple paralogs that may be regulated differentially and contribute to phenot...

This paper proposes an automated system for recognizing plant species based on leaf images. Plant leaf images corresponding to three plant types, are analyzed using three different shape modelling techniques, the first two based on the Moments-Invariant (M-I) model and the Centroid-Radii (C-R) model and the third based on a proposed technique of Binary-Superposition (B-S). For the M-I model the...
