The maize (Zea mays L.) Aux/IAA protein RUM1 (ROOTLESS WITH UNDETECTABLE MERISTEMS 1) controls seminal and lateral root initiation. To identify RUM1-dependent gene expression patterns, RNA-Seq of the differentiation zone of primary roots of rum1 mutants and the wild type was performed in four biological replicates. In total, 2 801 high-confidence maize genes displayed differential gene expressi...

Sorghum [ bicolor (L.) ] is a tropical grass that often suffers from structural failure (lodging) when subjected to wind, rain, and hail. During lodging, excessive lateral deflection occurs, which inherently correlates with the biomechanical properties of stem. As such, fundamental understanding sorghum's behavior required mitigate its propensity for lodging. Herein, we perform creep tests char...

The stem and leaf anatomical studies of Euphorbia hirta L. were conducted for finding identical traits. The fresh hand sections were stained with safranin and examined under light microscope. Cross section of the stem has a circular shape where epidermis was uniseriate and isodiametric. Cortex was distinctly formed with about 5-6 rows composed of chlorenchyma and found laticifers. Tracheary ele...

Cichoric acid is the main phenolic compound in the root and rhizome of the medicinal part, Echinacea purpurea that is known for possessing immune enhancing characteristics. In this study, we analysis the the synthesis and storage sites of phenolic compound in E. purpurea. We used fluorescent microscopy, transmission electron microscopy, cytochemical and immunocytochemical localization to observ...

BACKGROUND Helleborus niger L (Ranunculaceae) is used Ayurvedic and Unani systems and other herbal medicine systems. The roots of H. niger have a good medicinal value. AIMS To conduct a pharmacognostical and phytochemical study of H. niger. MATERIALS AND METHODS The pharmacognostical studies on roots including parameters such as taxonomical, macroscopic, microscopic characters, physico-chem...

A new turn-on cell permeable chemodosimetric probe has been developed and its application in the selective detection of trivalent cations (Fe(3+)/Cr(3+)/Al(3+)) at a sub-nanomolar level has been demonstrated. The selectivity of over a broad spectrum of mono- and divalent metal ions was established using fluorescence spectroscopy. Moreover, the changes in the absorption spectra of in the presenc...

Colour parameters of European beech were measured using CIELab system. 103 logs from 87 trees in 9 sites were cut into boards to study the variations of wood colour parameters. Both site and tree effect on colour were observed. Patterns of red heartwood occurrence were defined. When excepting red heartwood there was still a highly significant effect of site and tree; differences remained after ...

Time-of-flight is a time for an ultrasonic pulse to cross a sample. It contains valuable information about the mechanical properties of a material. For the ultrasonic pulse propagating in wood perpendicular to the grain the relation between the time-of-flight and the elastic constants is rather complex due to the strong anisotropicity of wood. With the help of some assumptions this relation can...

Flight necessitates that the feather rachis is extremely tough and light. Yet, the crucial filamentous hierarchy of the rachis is unknown-study hindered by the tight chemical bonding between the filaments and matrix. We used novel microbial biodegradation to delineate the fibres of the rachidial cortex in situ. It revealed the thickest keratin filaments known to date (factor >10), approximately...
