Plant science moves from mapping genomes to understanding what genes do

Genomics
Every drought-tolerant tomato variety or disease-resistant apple tree you'll see at the nursery in coming years traces back to researchers figuring out which genes actually matter, not just listing them.
For years, scientists raced to spell out the complete genetic code of major crop plants, like reading every letter in a massive instruction manual. Now that many of those manuals are finished, the harder work begins: figuring out what each instruction actually does and how to use that knowledge to breed better, hardier plants. This review looks at the tools and approaches researchers are using to make that leap from raw genetic data to real plant improvements.
Key Findings
Completion of major plant genome sequencing projects has shifted research focus toward functional genomics, determining what individual genes actually do
New molecular tools allow researchers to compare genes across different plant species to find shared functions and unique adaptations
Post-genome research aims to translate raw sequence data into practical applications like crop breeding and trait improvement

This is a review discussing how plant science has shifted from sequencing genomes to actually figuring out what genes do and how to use that knowledge to improve crops. It's a big-picture look at where genetics research goes after the genome-mapping race ends.
