Genetic variation and possible origins of weedy rice found in California

Ecology and Evolution, 2019
Control of weeds in cultivated crops is a pivotal component in successful crop production allowing higher yield and higher quality. In rice‐growing regions worldwide, weedy rice (Oryza sativa f. spontanea Rosh.) is a weed related to cultivated rice which

Paddy soil fertility shifts microbial metabolic quotient by regulating the selective enrichment of specific bacterial groups

Geoderma
The heterogeneous distribution of specific microbial taxa with diverse physiological traits, caused by changes of soil fertility level, controls community-level functions.

Patterns of selective constraints in noncoding DNA of rice [PDF]

, 2007
Background Several studies have investigated the relationships between selective constraints in introns and their length, GC content and location within genes. To date, however, no such investigation has been done in plants.

Evidence for the Emergence of New Rice Types of Interspecific Hybrid Origin in West African Farmers' Fields

, 2009
In West Africa two rice species (Oryza glaberrima Steud. and Oryza sativa L.) co-exist. Although originally it was thought that interspecific hybridization is impossible without biotechnological methods, progenies of hybridization appear to occur in ...

Transforming waste into resource: Ammonia plasma-modified biochar for efficient phosphate removal and fertilizer use in rice cultivation

Industrial Crops and Products
Effective phosphate recovery from wastewater and its reutilization are crucial for mitigating water eutrophication and achieving resource-efficient pollutant management. In this study, we developed a low-cost, high-efficiency adsorbent by modifying water

Functional Haplotypes and Evolutionary Insight into the Granule-Bound Starch Synthase II (GBSSII) Gene in Korean Rice Accessions (KRICE_CORE)

Foods, 2021
Granule-bound starch synthase 2 (GBSSII), a paralogous isoform of GBSSI, carries out amylose biosynthesis in rice. Unlike GBSSI, it mainly functions in transient organs, such as leaves.

Dualistic roles and management of non-cultivated plants in lowland rice systems of East Africa [PDF]

, 2017
An ethnobotanical study in lowland rice areas in East Africa was undertaken to assess farmers' knowledge on the usage of non-cultivated plants occurring in paddy fields, and to understand what rice farmers in this region do with useful species once they ...

Molecular evolution of the rice blast resistance gene Pi-ta in invasive weedy rice in the USA. [PDF]

PLoS ONE, 2011
The Pi-ta gene in rice has been effectively used to control rice blast disease caused by Magnaporthe oryzae worldwide. Despite a number of studies that reported the Pi-ta gene in domesticated rice and wild species, little is known about how the Pi-ta ...

Little White Lies: Pericarp Color Provides Insights into the Origins and Evolution of Southeast Asian Weedy Rice

G3: Genes, Genomes, Genetics, 2016
Weedy rice is a conspecific form of cultivated rice (Oryza sativa L.) that infests rice fields and results in severe crop losses. Weed strains in different world regions appear to have originated multiple times from different domesticated and/or wild ...

A Rare Allele of ST5 From Wild Rice Enhances Salt Tolerance in Rice

Advanced Science, EarlyView.
A novel salt‐tolerance gene ST5W, characterized by a unique 36‐bp promoter insertion, is found exclusively in a small subset of Oryza rufipogon and is absent in cultivated rice. Field trials confirm ST5W significantly enhances rice yield across diverse genetic backgrounds under saline conditions.
