Ethylene represents an important regulatory signal for root development. Genetic studies in Arabidopsis thaliana have demonstrated that ethylene inhibition of root growth involves another hormone signal, auxin. This study investigated why auxin was required by ethylene to regulate root growth. We initially observed that ethylene positively controls auxin biosynthesis in the root apex. We subseq...

After one decade of analyzing the intrinsic properties of graphene, interest into the development of graphene-based devices and micro electromechanical systems is increasing. Here, we fabricate graphene-coated atomic force microscope tips by growing the graphene on copper foil and transferring it onto the apex of a commercially available AFM tip. The resulting tip exhibits surprising enhanced r...

Flowering in plants is a consequence of the transition of the shoot apex from vegetative to reproductive growth in response to environmental and internal signals. The indeterminate1 gene (id1) controls the transition to flowering in maize. We show by cloning the id1 gene that it encodes a protein with zinc finger motifs, suggesting that the id1 gene product functions as a transcriptional regula...

The present study describes the morphometry of a unilateral ossified sacrotuberous ligament. It aims to discuss its Anatomical and clinical implications.The pudendal nerve, internal pudendal artery, nerve to obturator internus and coccygeal branch of inferior gluteal artery, are the important structures related to sacrotuberous ligament. An ossified sacrotuberous ligament may be an important et...

A novel apex-modified cyclotriveratrylene (CTV) derivative with an attached thiolane-containing lipoic acid linker was directly patterned onto gold substrates via dip-pen nanolithography (DPN). The addition of a dithiolane-containing linker to the apex of CTV provides a molecule that can adhere to a gold surface with its bowl-shaped cavity directed away from the surface, thereby providing a sur...

Light can penetrate several centimeters below the soil surface. Growth, development and behavior of plant roots are markedly affected by light despite their underground lifestyle. Early studies provided contrasting information on the spatial and temporal distribution of light-sensing cells in the apical region of root apex and discussed the physiological roles of plant hormones in root response...

Regenerative endodontic procedures are the emerging techniques for the restoration of functional pulp and dentine. The case report presented here describes the management of a symptomatic mandibular first molar with an immature apex and necrotic pulp in a 9 year old child. The tooth was tender on percussion and palpation and elicited a negative response to sensibility testing. A regenerative en...
