The Rulebook of Flowering Plant Genetics has been rewritten by scientists
How do you study a group of dispersed organisms with over 300,000 species, across all seven continents, and with up to 50 times as much DNA content as the human genome? This is the question posed to biologists studying the evolutionary history of flowering plants. The initiative combines new and innovative DNA sequencing techniques with genetic information from 1KP, a massive data resource with DNA from more than 1000 species that took an international team over a decade to complete.
They began stitching together the tree of life. Some researchers began specializing in the opposite approach at the turn of the century after the advent of next-generation sequencing, which used to be used to assemble trees by examining just a small number of genes. The first test case, the Human Genome Project, was completed in 2003 and spurred the new age of genomics.
Costs are high for many researchers. While knowing the genetic code of an organisms entire genome can be useful when trying to answer specific questions, comparing genomes is an inefficient way of figuring out relationships. This method of retrieving DNA has boomed in popularity in the past few years, allowing scientists to fill in the branches and leaves on the tree of life to probe both deeply and widely within and between species Every time a researcher wants to analyze evolutionary patterns in a group of organisms, they have to design new probes to extract genetic information.
They are starting to reap the rewards of their labor after the release of two combined probe sets. Over 500 genera and several times as many species are encompassed in the 20 studies published in these special issues. Each study zooms in on a specific group at different magnifications because of the broad utility of the probes.
The main branches of the angiosperm tree of life are constructed with the help of these strands. The splash zone is where most of the probes adhere to small portions of DNA that flank either end of aprotein-coding strand. The types of genes used for forensic testing in crime labs are similar to those used for non-coding DNA. equence capture can be used in plants to illuminate close relationships among closely related species or to reveal patterns of genetic diversity among individuals.
In a field where estimates suggest the majority of the plant species yet to be discovered have already been collected and stored in herbaria, this feature is very important. After they had gone extinct in the wild, some species were only discovered through genetic analysis. The studies in these issues offer a glimpse into the future of plant phylogenetics, one in which researchers can obtain immense quantities of data in a fraction of the time it would have The future looks good for Baker, who will be publishing data for over 7,000 flowering plant genera later this year.
He and several colleagues have been using the new probe set to construct the plant tree of life through the PAFTOL project. The standardization of targeted genes will pay dividends for decades to come, as we inch towards our collective goal. Settling a family feud is a high-level phylogenomic framework for the Gentianales based on 353 nuclear genes and partial plastomes.
