Size selective recognition of siRNA by an RNA silencing suppressor
Article Abstract:
Research shows that the RNA silencing suppressor protein of the Carnation Italian ringspot virus exhibits a high affinity for 21 nt siRNAs without disrupting standard A form of double-stranded RNA structure as revealed by the crystal structure of the virus protein in complex with a 21 nt siRNA. Data indicate that the protein acts as a molecular caliper and specifically select siRNAs based on the RNA duplex region length.

A quick release mechanism for abscisic acid
Article Abstract:
The research work about a stress hormone, abscisic acid (ABA) found in plant enables plants to survive recurring stresses such as drought, cold, and high salt in soils. The findings demonstrate that the cleavage of glucose-conjugated ABA by an ABA-specific [beta]-glucosidase, AtBG1, is a new way to produce bioactive ABA in response to dehydration stress and also day/night conditions.

Host-microbe interactions: Shaping the evolution of the plant immune response
Article Abstract:
The evolution of the plant immune response has culminated in a highly effective defense system that is able to resist potential attack by microbial pathogens. The important discoveries about the plant immune response over the last decade from 2006 are discussed.
