Description
Lara Marino and co-authors breed a forage grass that could make milk healthier and cows less gassy. The key fat, alpha-linolenic acid or omega-3, comes from what cattle eat, and richer forage raises milk's omega-3 share while cutting methane. Their 2024 paper works on Paspalum notatum, a pasture grass, aiming for high omega-3 leaves plus apomixis, the trick of reproducing by clonal seed.
The team assembled the grass's leaf gene catalog in both normal and doubled-chromosome forms. They recovered two lipid genes tied to fat profiles and built primers to copy every version of them in leaves. Guided by gene and fat measurements, they crossed plants toward hybrids that clone themselves through seed while packing more omega-3. Such hybrids would keep their winning traits in every generation without re-crossing. The work points toward pastures that improve both food quality and farm emissions.
