Genome Editing in Diatoms Using CRISPR-Cas to Induce Precise Bi-allelic Deletions

[Abstract]  Genome editing in diatoms has recently been established for the model species Phaeodactylum tricornutum and Thalassiosira pseudonana. The present protocol, although developed for T. pseudonana, can be modified to edit any diatom genome as we utilize the flexible, modular Golden Gate cloning system. The main steps include how to design a construct using Golden Gate cloning for targeting two sites, allowing a precise deletion to be introduced into the target gene. The ...

MNase Digestion for Nucleosome Mapping in Neurospora

[Abstract]  Digestion of chromatin by micrococcal nuclease MNase followed by high throughput sequencing allows us to determine the location and occupancy of nucleosomes on the genome. Here in this protocol we have described optimized conditions of MNase digestion of filamentous fungus Neurospora crassa chromatin without a requirement of a nuclear fractionation step.

Biolistic Bombardment for Co-expression of Proteins Fused to YFP and mRFP in Leaf Epidermal Cells of Phaseolus vulgaris ‘Red Mexican’

[Abstract]  Biolistic bombardment is based on coating of tungsten or gold particles with DNA and delivery of these “biobullets” into living plant cells under high pressure (Sudowe and Reske-Kunz, 2013). This method enables transient expression of a DNA construct encoding fusion of the protein of interest to a fluorescence protein e.g. GFP for microscopic approaches. Usually it is performed for plants for which infiltration with Agrobacterium tumefaciens does not work efficiently e.g. ...
