Scientists edit several rice genes at once to build better plants

Crispr
The rice on dinner tables worldwide depends on breeders stacking good traits together, and this faster multi-gene editing approach could speed up how quickly sturdier, higher-yielding varieties reach farmers' fields.
Rice breeders usually have to cross plants over many generations to combine several good traits into one variety, which is slow. This study used CRISPR, a precise gene-editing tool, to change multiple genes in rice at the same time, directly building a plant with an ideal combination of traits like strong stems and good grain production in far fewer steps.
Key Findings
CRISPR/Cas9 was used to edit multiple target genes simultaneously in a single rice genome, rather than one gene at a time.
The multiplex editing approach produced rice lines with combined improvements to plant architecture traits considered part of an 'ideal' high-yield plant type.
The method demonstrates a faster path to stacking beneficial agronomic traits compared to traditional cross-breeding.

Rice is a cereal grain and in its domesticated form is the staple food of over half of the world's population, particularly in Asia and Africa. Rice is the seed of the grass species Oryza sativa —or, much less commonly, Oryza glaberrima. Asian rice was domesticated in China some 13,500 to 8,200 y...
