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

Last paper of 2011: Natural variation in A. thaliana miRNAs

Another paper from the Todesco/Balasubramanian duo, in collaboration with the Altmann

Just published online in Current Biology

In this paper, we demonstrate that a naturally occurring polymorphism in the MIR164A gene affects leaf shape and shoot architecture in Arabidopsis thaliana, … Read the rest
