Isolated ABA mutants	Crossed mutant plants to a distinct ecotype and performed whole-genome sequencing on pooled mutants derived from the cross	(Stevenson et al., 2016)
Temperature-sensitive mutant screen identifying mutants that are unable to grow protonemata at the restrictive temperature	Crossed mutant plants to a distinct ecotype and performed whole-genome sequencing on pooled mutants derived from the cross	(Ding et al., 2018)
Isolated mutants that were unable to form gametophores in an effort to find genes involved in the transition from two-dimensional to three-dimensional growth	Took advantage of the ability of moss to form somatic hybrids; crossed two somatic hybrids to generate a mapping population and performed whole-genome sequencing on mutants derived from the cross	(Moody et al., 2018a)
