Arabidopsis naturally self-pollinates, the generation of cross-progeny requires some intervention by the investigator. This protocol describes the generation and collection of seeds by crossing suitable Arabidopsis parent plants. - [Read Setting Up Arabidopsis Crosses Protocol]
Protocol describes a method for vasectomy in which the vas deferens is accessed through the abdominal wall. Mice are ready for mating after ~10-14 days. Vasectomized males can be bred with fertile females to obtain plugs for timed matings. The pseudopregnant females can then be used for oviduct and uterine transfers. For an alternative protocol, see Vasectomy for Generation of Sterile Males: Access via Scrotal Sac. - [Read Vasectomy for Generation of Sterile Males: Access via Abdominal Wall Protocol]

The protocol gives general considerations for the design of targeting vectors for transgenic mice. The protocol shares tips in the design of knock-out and knock-in vectors and some of their strategies for producing homologously recombined embryonic stem cells.
