A cluster of Ankyrin and Ankyrin-TPR repeat genes is associated with panicle branching diversity in rice.

The number of grains per panicle is an important yield-related trait in cereals which depends in part on panicle branching complexity. One component of this complexity is the number of secondary branches per panicle. Previously, a GWAS site associated with secondary branch and spikelet numbers per p...
