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

Weedy rice: A threat to rice production in Sri Lanka

Journal of the University of Ruhuna, 2015
Weedy rice (Oryza sativa L. f. spontanea), one of the four most significant weeds, is globally well known as a problem in the rice industry. The economic and environmental problems they pose include those related to rice crop production, milling for commerce, quarantine regulations and seed trade.

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 ...

Genetic Characterization of Weedy Rices and the Inference on their Origins.

Japanese Journal of Breeding, 1997
Weedy rice is defined as rice plants growing as weeds in and around the arable lands. Various forms of weedy rice were observed in many rice growing countries, but are decreasing under intensive cultivation system. Origin of weedy form and its significance in rice domestication are the interesting but unsolved problems for rice evolutionists.
