banana
Bananas are the edible berry-like fruits of large herbaceous monocots in the genus Musa, notable for being produced by plants that are technically not trees despite their tree-like stature. They are a subject of significant plant science research due to their global agricultural importance, complex starch biochemistry, and vulnerability to pathogens like Fusarium wilt, which threatens commercial cultivars. Understanding banana genetics, ripening physiology, and disease resistance mechanisms is critical for securing food supply and advancing broader knowledge of monocot biology.

Scientists successfully used CRISPR gene editing in banana plants with near-perfect efficiency — 91% of edited plants showed a complete, uniform genetic change rather than the patchwork results that typically plague editing in crops with multiple gene copies. This solves a long-standing obstacle in improving bananas and other complex polyploid crops.
91% of 102 edited banana plants showed full albino phenotype, with 9% pale green — zero chimeric (mixed/partial) plants, indicating near-complete editing efficiency.
Tri-allelic editing was confirmed across all plants: all three gene copies were disrupted, with two carrying identical mutations and one a distinct mutation.
Tiny deletions of just 2–6 amino acids within the conserved binding motif were enough to fully abolish the gene's function, confirming the motif's essential role.
