ASK about the species and sequencing.
CHAT in a 30 minute text chat with the species champion.
VOTE for a species to be sequenced for the first time ever!
1,890 (counted in 2010)
0.49 picogram of DNA per genome
A three-way split of plants, animals and fungi is thought to have happened 1576 +/- 88 million years ago
I should be sequenced because...: I am hoping to discover more about my genetic diversity in the UK: perhaps this can explain why I am so endangered here

I have a complex relationship with my environment. Although I live near water I am actually not very tolerant to flooding. My seeds can germinate in water but my seedlings won’t survive in it for very long. So why do you think I live so close to rivers and lakes?
The reason is that I basically don’t like having taller plants around. I depend on winter flooding to get rid of more competitive plant species and clear the shores for myself and other low growing annuals and perennials. But if the water stays high after I germinate and does not go down, I drown.
If everything goes well and the waters recede enough when spring arrives, I thrive in the sunny, open spaces that remain. I love sunshine and do not like being shaded at all – even my seeds need light for germination.
Not only flooding can create these open shores for me: grazing by cattle can remove taller plants as well – or humans can help out, if there aren’t any cattle around. However, flooding during spring and summer can threaten my existence, as my plants do not tolerate water very well.
