Complementary gene controlling the black hull phenotype and phenolics and flavonoids content in weedy rice (Oryza sativa f. spontanea) from northeastern Thailand [PDF]
A complementary gene black seed hull 4 (Bh4 and Phr1) is a hull color candidate gene that causes a black pigmentation in the ripened hulls of rice. The relationship between Bh4 and Phr1 in the black hull phenotype was elucidated previously.

Genotype frequency of black hull locus (Bh4) in weedy rice (Oryza sativa f. spontanea) populations [PDF]
Black hull 4 (Bh4), is a hull color candidate gene that causes a black pigmentation in the ripened hulls of rice. A 22-bp deletion within exon 3 of the Bh4 variant disrupted the Bh4 function, which lead to a straw-white hull in Asian cultivated rice and ...
