Complementary gene controlling the black hull phenotype and phenolics and flavonoids content in weedy rice (Oryza sativa f. spontanea) from northeastern Thailand [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2019
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.

Diverse genetic mechanisms underlie worldwide convergent rice feralization

Genome Biology, 2020
Background Worldwide feralization of crop species into agricultural weeds threatens global food security. Weedy rice is a feral form of rice that infests paddies worldwide and aggressively outcompetes cultivated varieties. Despite increasing attention in

Variation in Oxidized Proanthocyanidins in Chinese Weedy Rice Seeds and Their Impact on Ecological Adaptation

Agronomy
Weedy rice, also known as red rice, mainly originates from the de-domestication of cultivated rice and is a vicious weed in paddy fields around the world. Its red seeds are rich in oxidized proanthocyanidins (OPAs).

Effect of tillage and burial depth and density of seed on viability and seedling emergence of weedy rice

Journal of Integrative Agriculture, 2019
Weedy rice (Oryza sativa f. spontanea) is one of the three worst paddy weeds in most rice growing areas. The unexpected heavy infestation is derived from a persistence of soil seed bank of weedy rice, which the shattered seeds chiefly feed back to ...
