Abstract Detail



Frontiers in fern gametophyte research

Sex, arsenic and the fern gametophyte.

While ferns have unique properties that make them essential in understanding plant development and evolution, they have extremely large genomes. This has made it difficult to identify the genes and mechanisms underlying their unique biology. New DNA sequencing technology plus statistical and bioinformatics tools have the potential to change our thinking about ferns as model systems. To illustration this point, we describe and compare how deep sequencing of transcripts (RNAseq) together with RNA interference has been used to understand the mechanisms underlying sex determination in gametophytes of Ceratopteris richardii and arsenic tolerance and hyperaccumulation in Pteris vittata.
