Kim et al. describe a novel protein, TmpL, involved in
development and virulence in both plant and animal pathogenic
fungi. Their findings provide new insights into mechanisms
underlying the complex web of interactions between reactive
oxygen species (ROS) and cell differentiation for both plant and
animal fungal pathogenesis.
David Bond and Edan Foley conduct a survey of the
entire Drosophila genome for novel regulators in the
Imd/dJNK pathway. The pair uncovers a novel link between the
proliferative Pvr pathway and the IMD pathway.
Ivanchenko et al. analyze the dynamics of HIV assembly
and release making use of fluorescently labeled HIV structural
proteins. The results add dynamic information to our picture of
virus release and provide an experimental basis for interfering
with this stage of virus replication.
