No genome needed: synteny- based precision mapping
Mapping-by-sequencing, “SHOREmapping”, is greatly accelerating the identification of causal mutations.
Current whole-genome or transcriptome assemblies from next-generation sequencing data of non-model organisms, however, do not produce chromosome-length scaffolds. We have therefore developed a method that exploits synteny with a related … Read the rest
MiRNA duplex structure controls secondary siRNA formation
Plant secondary siRNA production determined by microRNA-duplex structure.
Out in PNAS by Manavella and colleagues: Plant secondary siRNA production determined by microRNA-duplex structure. In plants, miRNA-mediated cleavage of a target triggers in some cases the production of secondary small interfering … Read the rest

New gene silencing method published: MIGS
Virus-induced gene silencing (VIGS) and hairpin RNA interference (hpRNAi), both of which rely on small interfering RNAs, together with artificial microRNAs (amiRNA), are amongst the most popular methods for reduction of gene activity in plants.
However, all three approaches have … Read the rest
