Exploratory survey of rice growing practices identifies perceptions and management of weedy rice
Weedy rice (_Oryza sativa_ L. spp.) is an emerging weed in California rice production. To address weedy rice issues and improve extension efforts, information is needed about the prevalence of growing practices that may contribute to or prevent weedy ...

Seed-mediated gene flow promotes genetic diversity of weedy rice within populations: implications for weed management. [PDF]
Increased infestation of weedy rice-a noxious agricultural pest has caused significant reduction of grain yield of cultivated rice (Oryza sativa) worldwide. Knowledge on genetic diversity and structure of weedy rice populations will facilitate the design

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.
