Abstract: This disclosure provides recombinant DNA constructs and transgenic plants having enhanced traits such as increased yield, increased nitrogen use efficiency, and enhanced drought tolerance or water use efficiency. Transgenic plants may include field crops as well as plant propagules and progeny of such transgenic plants. Methods of making and using such transgenic plants are also provided. This disclosure also provides methods of producing seed from such transgenic plants, growing such seed, and selecting progeny plants with enhanced traits. Also disclosed are transgenic plants with altered phenotypes which are useful for screening and selecting transgenic events for the desired enhanced trait.

Abstract: A sewer back-up alarm unit. It replaces the plug in an access opening. And, it has a solid wall with a short pivoted arm mounted on the inside of the wall. The arm is angled and pivots freely between two positions, as limited by the wall. There is a liquid level float that is hung from one end of the arm by a flexible chain. A counterweight is mounted on the other end of the arm to pivot it to the position opposite to the one which the weight of the float causes. There is a magnetic switch mounted on the outside of the solid wall, and a magnet on the arm actuates the switch when the float is raised by the level of liquid in the sewer. An alarm circuit may be connected to the switch, as desired.
