Phytohormone signaling is fine-tuned by regulatory feedback loops. The phytohormone abscisic acid (ABA) plays key roles in plant development and abiotic stress tolerance. PYRABACTIN RESISTENCE 1/PYR1-LIKE/REGULATORY COMPONENT OF ABA RECEPTOR (PYR/PYL/RCAR) receptors sense ABA, and in turn, ABA represses their expression.

Among them, (Trichostomatia, Pycnotrichidae), the largest described ciliate, is found exclusively associated with (capybara), the largest known rodent reaching up to 90 kg. Here, we present the sequence, structural and functional annotation of this giant microeukaryote macronuclear genome and discuss its phylogenetic placement.

Here, we report the identification and characterization of miRNAs in two closely related screwworm flies with different feeding habits: Cochliomyia hominivorax and Cochliomyia macellaria. The New World screwworm, C.
