Evaluation of Population Structure, Genetic Diversity and Origin of Northeast Asia Weedy Rice Based on Simple Sequence Repeat Markers

open access: yesRice Science, 2015
Weedy rice exerts a severe impact on rice production by competing for sunlight, water and nutrients. This study assayed the population structure, genetic diversity and origin of Northeast Asia weedy rice by using 48 simple sequence repeat markers.

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

open access: yesSongklanakarin 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.
