Models Used to Study Plant Development

Question 1

genetic criteria for a good model organism

Answer 1

§ short life cycle
§ easy to grow (small is good)
§ easy to cross
§ easy to mutagenize
§ easy to phenotype
§ haploid or diploid genome- don’t want massive genomes because recombination makes stuff quite complicated

genomic criteria for a good model organism

Answer 2

small haploid genome size

reference genome, which is sequenced and annotated
