Hypothesis
What are the regulatory genes involved in barley grain development?
Conclusion
The study identified key regulatory genes involved in barley seed development and created a genetic linkage map for further research.
Supporting Evidence
- 50 regulators were found to be preferentially expressed in specific grain tissue fractions during seed development.
- SNP-marker development resulted in anchoring 61 markers on the genetic linkage map of barley.
- The study revealed conserved chromosomal orders of mapped regulatory factors between barley and rice.
Takeaway
Scientists looked at many genes in barley to see which ones help the seeds grow, and they made a map to help study these genes more.
Methodology
The study involved expression profiling of 376 regulatory genes and SNP marker development for linkage mapping.
