MicroRNAs are essential regulators of gene expression and have been extensively studied in plants and animals; however, few reports have been published in mushrooms. Po-MilR-1 is a novel microRNA with a length of 22 bp in Pleurotus ostreatus . The secondary structures of five precursors and the target genes of Po-MilR-1 were predicted. Expression profile analysis showed Po-MilR-1 had specific expression in the primordium and fruiting body. To explore its physiological function, Po-MilR-1 was overexpressed in P. ostreatus . The transformants showed slow mycelium growth rate and abnormal pileus with irregular edge, which suggested Po-MilR-1 plays an important role in P. ostreatus development. Additionally, Po-MilR-1 and one of its target hydrophobin genes POH1 had opposite temporal expression profiles in the primordium and fruiting body, which revealed that Po-MilR-1 may perform its physiological function through the negative regulation of POH1 . This study explored the development-related function of a mushroom microRNA and will provide a reference for other microRNAs.

The CAN protocol is widely used in the distributed embedded systems. It has been shown that a shared-clock scheduling algorithm can be used along with CAN to implement time triggered architecture. However, the shared-clock scheduling algorithms are mostly used along with the time triggered cooperative schedulers, despite these algorithms provide reliable solutions for many applications, they suffer some key limitations. This paper proposes a shared-clock hybrid scheduling algorithm which employs the time triggered hybrid scheduler. And then the performance of the novel algorithm is analyzed. Finally, a simulation model is built by using TrueTime toolbox in MATLAB platform. The results indicate that the scheduler can improve clock synchronization accuracy, reduce the jitter, and strengthen the real-time character of the system.
