Azolla is a symbiotic superorganism that captures all the nitrogen fertilizer it needs to grow from the air around it. Asia’s farmers have long known this, growing Azolla together with rice to provide a natural fertilizer to bolster rice productivity.

Genome sequencing of Azolla is a big step toward potentially helping crops to use less synthetic nitrogen that would benefit farmers' bottom lines, the environment, and the prices we pay for food.

Budget

Budget Overview

Azolla is a 'superorganism', consisting of not just the fern but a diverse array of symbiotic bacteria. It is this unique microbiota that converts nitrogen into organic forms and makes Azolla a perfect bio-fertilizer. This fund will be used to sequence the genomes of Azolla and its symbiotic bacteria, so that we can understand the two-way, inter-kingdom language that codes for the molecular machinery underlying this symbiotic partnership, and possibly tailor it to suit our needs.

We will generate a draft Azolla genome using the high-throughput Illumina sequencing technology. Two paired-end, 150bp HiSeq runs will generate 160 giga-bases, giving over a 100X genome coverage. In addition, we will use PacBio technology to generate long DNA reads (>4kb) in order to better assemble the sequencing data into continuous genomic regions. The bacterial DNA will be extracted and sequenced together with Azolla's. Because of the high sequencing volume and smaller genomes, bacterial genomes can be easily assembled alongside with Azolla.

As a start, the funding of $15,000 will get us reasonably good quality genomes for the Azolla superorganism that can jumpstart various exciting research programs. Of course, additional support would give us all that much more leverage and take us further down the road!

Meet the Researcher

Background

Kathleen Pryer is a Duke professor of biology. She and her colleagues recently named a genus of ferns in honor of Lady Gaga. Kathleen has been studying ferns for 30+ years. She also loves cats. pryer@duke.edu

Fay-Wei Li is a PhD candidate at Duke whose recent fern research was covered by New York Times and The Economist. Fay-Wei is a fern enthusiast and wants to save the world with ferns.

Paul Wolf is a professor of biology at Utah State University. He has worked on ferns since 1983 and is interested in fern genomes and ferns with applications to humans. Paul enjoys running, especially on trails through the forest, or along the roads.

Carl Rothfels is a recent PhD graduate from Duke and is now doing a postdoc at UBC in Vancouver, Canada. He climbs rocks and collects ferns.

Erin Sigel is a PhD candidate at Duke who spends alot of time thinking about the evolution of plant genomes, particularly how they change due to interactions with other organisms. Erin also enjoys kayaking and baking.
