Knockout of a cytokinin oxidase/dehydrogenase boosts soybean yield

Soybean (Glycine max) is a vital oilseed crop and a major global source of high-quality protein and edible oil. With the increasing demand for soybean production, a central objective of soybean improvement is to identify yield-related genes and develop high-yielding varieties. Unlike rice and wheat, soybean yield components are inherently more complex, involving multiple traits such as plant height, number of inflorescence-bearing leaf axils (nodes), number of pods per node, seeds per pod, seed size, and seed weight.
