Identification of grain shape determining genes can facilitate breeding of rice cultivars with optimal grain shape and appearance quality. Here, we identify GS9 (Grain Shape Gene on Chromosome 9) gene by map-based cloning. The gs9 null mutant has slender grains, while overexpression GS9 results in round grains. GS9 encodes a protein without known conserved functional domain. It regulates grain shape by altering cell division. The interaction of GS9 and ovate family proteins OsOFP14 and OsOFP8 is modulated by OsGSK2 kinase, a key regulator of the brassinosteroids signaling pathway...

Quantifying metal and nanoparticle (NP) biouptake and distribution on an individual cellular basis has previously been impossible, given available techniques which provide qualitative data that are laborious to acquire and prone to artifacts. Quantifying metal and metal NP uptake and loss processes in environmental organisms will lead to mechanistic understanding of biouptake and improved understanding of potential hazards and risks of metals and NPs. In this work, we present a new technique, single cell inductively coupled plasma mass spectrometry (SC-ICP-MS), which allows quantification of metal concentrations on an individual cell basis down to the attogram (ag) per cell level...

This paper proposes the use of factorial experimental design as a standard experimental method in the application of froth flotation to plastic separation instead of the commonly used OVAT method (manipulation of one variable at a time). Furthermore, as is common practice in minerals flotation, the parameters of the kinetic model were used as process responses rather than the recovery of plastics in the separation products. To explain and illustrate the proposed methodology, a set of 32 experimental tests was performed using mixtures of two polymers with approximately the same density, PVC and PS (with mineral charges), with particle size ranging from 2 to 4 mm...

The analysis of genome-wide epigenomic alterations including DNA methylation has become a subject of intensive research for many complex diseases. Whole-genome bisulfite sequencing (WGBS) using next-generation sequencing technologies can be considered the gold standard for a comprehensive and quantitative analysis of cytosine methylation throughout the genome. Several approaches including tagmentation- and post bisulfite adaptor tagging (PBAT)-based WGBS have been devised. Here, we provide a detailed protocol based on a commercial kit for the preparation of libraries for WGBS from limited amounts of input DNA (50-100 ng) using the classical approach of WGBS by ligation of methylated adaptors to the fragmented DNA prior to bisulfite conversion...

Characterization of OVATE family proteins (OFPs) has revealed that they exert functions by interacting with different types of transcription factor. However, the molecular bases of these processes are poorly understood. Here, we report that OsOFP19 negatively modulates brassinosteroid (BR) response and integrates it with the cell division pattern to affect plant architecture, including grain shape, through interaction with both DWARF AND LOW-TILLERING (DLT) and Oryza sativa homeobox1 (OSH1). Overexpression of OsOFP19 caused a semi-dwarf stature with thicker leaves and stronger culms and roots, which result from an increase in cell layers in the sub-epidermal tissue...

We report on a 54-year-old man who presented with an atypical, proximal, intraoperative endoleak after endovascular aortic repair with an Ovation endograft for a 65-mm-diameter abdominal aortic aneurysm. The endografting was complicated by inadvertent bilateral iliac limb insertion into the right gate without cannulation of the left gate. The endoleak was treated by brachial approach: Through the open left gate, the outflow inferior mesenteric artery was coil embolized and the inflow left gate was closed with an Amplatzer plug...
