Snapshots of the Signaling Complex DesK:DesR in Different Functional States Using Rational Mutagenesis and X-ray Crystallography
[Abstract]  We have developed protocols to generate site-specific variants of the histidine-kinase DesK and its cognate response regulator DesR, conducive to trapping different signaling states of the proteins. Co-expression of both partners in E. coli, ensuring an excess of the regulator, was essential for soluble production of the DesK:DesR complexes and further purification. The 3D structures of the complex trapped in the phosphotransferase and in the phosphatase reaction steps, were solved by ...

A Ribosome Footprinting Protocol for Plants
[Abstract]  Ribosome footprinting, or Ribo-seq, has revolutionized the studies of translation. It was originally developed for yeast and mammalian cells in culture (Ingolia et al., 2009). Herein, we describe a plant-optimized hands-on ribosome footprinting protocol derived from previously published procedures of polysome isolation (Ingolia et al., 2009; Mustroph et al., 2009) and ribosome footprinting (Ingolia et al., 2009; Ingolia et al., 2013). With this ...

Targeted Gene Mutation in Rice Using a CRISPR-Cas9 System
[Abstract]  RNA-guided genome editing (RGE) using bacterial type II cluster regularly interspaced short palindromic repeats (CRISPR)–associated nuclease (Cas) has emerged as a simple and versatile tool for genome editing in many organisms including plant and crop species. In RGE based on the Streptococcus pyogenes CRISPR-Cas9 system, the Cas9 nuclease is directed by a short single guide RNA (gRNA or sgRNA) to generate double-strand breaks (DSB) at the specific sites of chromosomal DNA, thereby ...
