Other model plants

Why is arabidopsis not always a good model plant

Key crops are monocots

Uses C3 photosynthesis

No mycorrhizae in Brassicacea

Some large gene families

Other plants are smaller, ximpler and produce more propagules

What are the model bryophytes

Marchantia polymorpha

Physcomitrella patens

What kind of bryophyte is M. polymorpha

A thalloid liverwort

What gametophyte dominates in M. polymorpha

Haploid

Why is m. polymorpha the model bryophyte

Simple genetic network

No whole genome duplications

Easy to grow - ubiquitous

How can Marchantia be made to reproduce

Gametogenesis induced by exposure to far red light

Makes lots og single-celled spores

How can Marchantia be asexulaly reproduced

Using gemmae - small discs of clonal haploid tissue

What type of bryophyte is P. patens

a moss

What is P. patens useful in

Bioreactors

What is the model lycophyte

Selaginella moellendorffii

What kind of lycophyte is moellendorffii

Clubmoss

What is S. moellendorffii used in

Comparative genomtics

What is the model monilophyte

Ceratopteris richardii

Why is the monocot maize a bad model

Large genome

3-4 month generation time

Need lots of space and light

What is emerging as an important model monocot

Brachypodium distachyon

small, fast growing
