Abstract: Provided are a mutant HPPD polypeptide having high resistance to a herbicide and an encoding gene thereof, and an application thereof in an improved plant. The amino acid at position 282 of the mutant HPPD polypeptide is mutated from arginine to serine at a wild-type HPPD polypeptide. In addition, the mutant HPPD polypeptide further comprises an amino acid at position 349 that is mutated from glutamic acid to lysine, and/or an amino acid at position 156 that is mutated from alanine to valine. The mutated HPPD polypeptide can be used for cultivating plants having resistance to a herbicide having HPPD inhibition.

Abstract: A base station antenna and a base station including the base station antenna are provided. A base station antenna includes a transceiver array configured to output M signals, wherein M is an integer greater than 1; an antenna array including N antenna units, wherein N is an integer greater than M; a first-level signal allocating network configured to allocate first power to the M signals, and output P signals, wherein P is an integer greater than M; a signal synthesizing network including multiple signal synthesizers, wherein each of the multiple signal synthesizers utilizes two signals of the P signals to synthesize two output signals; and a second-level signal allocating network configured to allocate second power to signals output by the multiple signal synthesizers, and output N signals to the N antenna units.
