New web tool makes precise gene editing in wheat easier

Wheat's triple genome has long made it hard to edit just one gene copy without accidentally hitting its near-identical twins, so a tool that can tell those copies apart could speed up breeding hardier, more nutritious bread wheat.
Wheat is unusual because it actually carries three full sets of genes stacked together, which makes it hard for scientists to edit just one version of a gene without messing with its near-duplicates. This new online tool, called WheatTarget, scans wheat's genome and helps researchers pick CRISPR editing targets that are specific to just the gene copy they want to change. That precision could make it faster and safer to develop wheat varieties with better disease resistance, drought tolerance, or nutrition.
Key Findings
WheatTarget is a web-based platform designed specifically for wheat's subgenome structure (three homoeologous genomes: A, B, D).
The tool helps researchers design CRISPR guide RNAs that can target single subgenome copies or all three copies simultaneously, depending on the breeding goal.
The webserver aims to reduce off-target editing errors that are common when applying standard CRISPR design tools to wheat's complex polyploid genome.

Scientists built a free online tool called WheatTarget that helps researchers design precise gene-editing experiments in wheat, a notoriously tricky crop to edit because it carries three copies of its genome.

Wheat is a group of wild and domesticated grasses of the genus Triticum. As cereals, they are cultivated for their grains, which are staple foods around the world. Well-known wheat species and hybrids include the most widely grown common wheat, spelt, durum, emmer, einkorn, and Khorasan or Kamut....
