Regulation of abscisic acid receptor mRNA stability: involvement of microRNA5628 in PYL6 transcript decay.

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.

In Vitro and In Planta Studies on Temperature Adaptation of Isolates from Maize in Europe and South America.

Northern Corn Leaf Blight (NCLB) is a fungal leaf disease in maize caused by . NCLB occurs worldwide, from tropical to temperate zones raising the question about plasticity of temperature adaptation of local isolates of the pathogen. Seven isolates of originating from South America and seven from Europe were compared for their response to temperature variations in vitro and in vivo between 15 and 30 °C.
