encoding a chromatin remodeling factor, is a killer causing hybrid sterility between rice species and .

The genetic mechanisms of reproductive isolation have been widely investigated within Asian cultivated rice (); however, relevant genes between diverged species have been in sighted rather less. Herein, a gene showing selfish behavior was discovered in hybrids between the distantly related rice species and . The selfish allele in the locus impaired male fertility, discriminately eliminating pollens containing the allele from in heterozygotes (/).

Different contributions of PROG1 and TAC1 to the angular kinematics of the main culm and tillers of wild rice (Oryza rufipogon).

PROG1 is necessary but insufficient for the main culm inclination while TAC1 partially takes part in it, and both genes promote tiller inclination in Asian wild rice. Asian wild rice (Oryza rufipogon), the ancestor of cultivated rice (O. sativa), has a prostrate architecture, with tillers branching from near the ground.
