Researchers surprised by plant genome variability: adaptation to environment stronger effect than anticipated

Faster growth, darker leaves, a different way of branching - wild varieties of the plant Arabidopsis thaliana are often substantially different from the laboratory strain of this small mustard plant, a favorite of many plant biologists. Which detailed differences distinguish the genomes of strains from the polar circle or the subtropics, from America, Africa or Asia has been investigated for the first time by research teams from Tübingen, Germany, and California led by Detlef Weigel from the Max Planck Institute for Developmental Biology. The results were surprising: the extent of the genetic differences far exceeds the expectations for such a streamlined genome, as the scientists write in this week’s edition of Science magazine.

The findings [*abstract] challenge the idea that the genome of a single indivual of a species captures the essence of the species as a whole. There is no such thing as one genome. Instead there is great variability across strains. The genetic variability found for Arabidopsis appears to reflect adaptation to local circumstances. It is likely that such variable genes allow plants to withstand dry or wet, hot or cold conditions, or make use of short and long growing seasons.

This makes the discovery important for plant breeders, because such genome analyses of unprecedented details will allow for a much better understanding of local adaptation to ever changing environments. And indeed, Weigel is already collaborating with the International Rice Research Institute (IRRI) in the Philippines to apply the methods and experience gathered with Arabidopsis to twenty different rice varieties.
By extending these types of studies to other species we hope to help breeders to produce varieties that are optimally adapted to rapidly changing environmental conditions. - Detlef Weigel, Max Planck Institute for Developmental Biology
To track down the variation in the genome of the different Arabidopsis strains, the researchers compared the genetic material of 19 wild strains with that of the genome of the lab strain, which was sequenced in the year 2000. Using a very elaborate procedure, they examined every one of the roughly 120 million building blocks of the genome. For their molecular sleuthing they used almost one billion specially designed DNA probes. Illustrating the extent of the project, Weigel says that all together, these probes would have seven times the length of human genome. The data were evaluated with several specially designed statistical methods, including a variant of machine learning:
:: :: :: :: :: :: :: :: :: :: ::

The result of this painstaking analysis: on average, every 180th DNA building block is variable. And about four percent of the reference genome either looks very different in the wild varieties, or cannot be found at all. Almost every tenth gene was so defective that it could not fulfill its normal function anymore.

Results such as these raise fundamental questions. For one, they qualify the value of the model genomes sequenced so far.
There isn’t such a thing as the genome of a species. The insight that the DNA sequence of a single individual is by far not sufficient to understand the genetic potential of a species also fuels current efforts in human genetics. - Detlef Weigel, Max Planck Institute for Developmental Biology
Still, it is surprising that Arabidopsis has such a plastic genome. In contrast to the genome of humans or many crop plants such as corn, that of Arabidopsis is very much streamlined, and its size is less than a twentieth of that of humans or corn—even though it has about the same number of genes. In contrast to these other genomes, there are few repeats or seemingly irrelevant filler sequences. That even in a minimal genome every tenth gene is dispensable, has been a great surprise, admits Weigel.

Detailed analyses showed that genes for basic cellular functions such as protein production or gene regulation rarely suffer knockout hits. Genes that are important for the interaction with other organisms, on the other hand, such as those responsible for defense against pathogens or infections, are much more variable than the average gene. The genetic variability appears to reflect adaptation of local circumstances, says Weigel. It is likely that such variable genes allow plants to withstand dry or wet, hot or cold conditions, or make use of short and long growing seasons. The findings have obvious implication for plant breeders, who can now use the knowledge to breed crops much more adapted to local environmental circumstances.

How environment and genome interact is also the goal of new, even more powerful methods. While the technology used so far can only identify genes that have changed or are lost relative to the reference genome, direct sequencing of the genome of wild strains will allow the detection of new genes. The plan is to decipher the genomes of at least 1001 Arabidopsis varieties. A new instrument, with which the entire genome of a plant can be read in just a few days, is already available. Still missing are the computational algorithms to interpret the anticipated flood of data.

Researchers from Tübingen who contributed to the study include Richard Clark, Stephan Ossowski and Norman Warthmann from the MPI for Developmental Biology, Georg Zeller and Gunnar Rätsch from the Friedrich Miescher Laboratory of the Max Planck Society, Gabriele Schweikert and Bernhard Schölkopf from the MPI for Biological Cybernetics, and Daniel Huson from the University Tübingen. Researchers from California who contributed to this study include Huaming Chen, Paul Shinn and Joseph Ecker from the Salk Institute, Christopher Toomajian, Tina Hu and Magnus Nordborg from the University of Southern California, and Glenn Fu, David Hinds and Kelly Frazer from Perlegen Sciences, Inc.
