Small RNAs, including microRNAs (miRNAs), small interfering RNAs
(siRNAs), and trans-acting siRNAs (tasiRNAs), control gene expression
and epigenetic regulation. Although the roles of miRNAs and
siRNAs have been extensively studied, their expression diversity
and evolution in closely related species and interspecific hybrids
are poorly understood. Here, we show comprehensive analyses...
Background
Two major mycoparasitic lineages, the family Hypocreaceae and the genus Tolypocladium, exist within the fungal order, Hypocreales. Peptaibiotics are a group of secondary metabolites almost exclusively described from Trichoderma species of Hypocreaceae. Peptaibiotics are produced by nonribosomal peptide synthetases (NRPSs) and have antibiotic and antifungal activities. Tolypocladium species are...
The Columbia Basin once supported a diversity of native fishes and large runs of anadromous salmonids that sustained substantial fisheries and cultural values. Extensive land conversion, watershed disruptions, and subsequent fishery declines have led to one of the most ambitious restoration programs in the world. Progress has been made, but...
