Revision of the fungus-growing ant genera Mycetophylax Emery and Paramycetophylax Kusnezov rev. stat., and description of Kalathomyrmex n. gen. (Formicidae: Myrmicinae: Attini)

Based on the morphology of workers, gynes and males, we revise the taxonomy of nominal taxa traditionally included by authors in the fungus-growing ant genus Mycetophylax. Our results indicate that Mycetophylax Emery (Myrmicocrypta brittoni Wheeler, 1907, type species, by designation of Emery, 1913; junior synonym of Cyphomyrmex conformis Mayr, 1884 by Kempf, 1962) includes M. conformis, M. simplex (Emery, 1888), and M. morschi (Emery, 1888) new combination (formerly in Cyphomyrmex), with several synonymies. Mycetophylax bruchi (Santschi, 1916) does not belong to the same genus and is diagnosed, in addition to other characters, by a psammophore arising at the anterior margin of the clypeus. For this species we are resurrecting from synonymy Paramycetophylax Kusnezov, 1956 (Mycetophylax bruchi as type species, by original designation, with M. cristulatus as its new synonym). Myrmicocrypta emeryi Forel, 1907 is the only attine in which females lack the median clypeal seta and have the antennal insertion areas very much enlarged and anteriorly produced, with the psammophore setae arising from the middle of the clypeus and not at its anterior margin as in Paramycetophylax. Notwithstanding its inclusion in Mycetophylax by recent authors, it is here recognized as belonging to a hitherto undescribed, thus far monotypic genus, Kalathomyrmex new genus (Myrmicocrypta emeryi as its type species, here designated). We redescribe workers, gynes and males of all species in the three genera and describe for the first time gynes of Mycetophylax conformis and M. simplex, males of M. simplex and M. morschi, and gynes of P. bruchi. Furthermore we present a key to the workers of the taxa treated here (most formerly included under the name Mycetophylax), a key to workers of the Mycetophylax in the revised sense, SEM pictures and high resolution AutoMontage(C) photographs of the species, along with maps of collection records and a summary of biological observations.

Inhibition of HIV-1 multiplication by a modified U7 snRNA inducing Tat and Rev exon skipping

The HIV-1 regulatory proteins Tat and Rev are encoded by multiply spliced mRNAs that differ by the use of alternative 3' splice sites at the beginning of the internal exon. If these internal exons are skipped, the expression of these genes, and hence HIV-1 multiplication, should be inhibited. We have previously developed a strategy, based on antisense derivatives of U7 small nuclear RNA, that allows us to induce the skipping of an internal exon in virtually any gene. Here, we have successfully applied this approach to induce a partial skipping of the Tat, Rev (and Nef) internal exons. Three functional U7 constructs were subcloned into a lentiviral vector. Two of them strongly reduced the efficiency of lentiviral particle production compared to vectors carrying either no U7 insert or unrelated U7 cassettes. This defect could be partly or fully compensated by coexpressing Rev from an unspliced mRNA in the producing cell line. Upon stable transduction into CEM-SS or CEM T-lymphocytes, the most efficient of these constructs inhibits HIV-1 multiplication. Although the inhibition is not complete, it is more efficient in combination with another mechanism inhibiting HIV multiplication. Therefore, this new approach targeting HIV-1 regulatory genes at the level of pre-mRNA splicing, in combination with other antiviral strategies, may be a useful new tool in the fight against HIV/AIDS.
