Do aeration conditions affect arsenic and phosphate accumulation and phosphate transporter expression in rice (Oryza sativa L.)?

Iron Bioavailability and Arsenic Uptake in Rice (Oryza sativa L.)

OsARF16 Is Involved in Cytokinin-Mediated Inhibition of Phosphate Transport and Phosphate Signaling in Rice (Oryza sativa L.)

BACKGROUND Plant responses to phytohormone stimuli are the most important biological features for plants to survive in a complex environment. Cytokinin regulates growth and nutrient homeostasis, such as the phosphate (Pi) starvation response and Pi uptake in plants. However, the mechanisms underlying how cytokinin participates in Pi uptake and Pi signaling are largely unknown. In this study, we...

Arsenic Accumulation in Rice ( Oryza sativa L . ) Varieties of 1 Bangladesh : A Glass House Study

26 A glass house study was conducted to investigate the accumulation of arsenic in tissues of five 27 widely cultivated rice (Oryza sativa L.) varieties of Bangladesh namely BRRI dhan 28, BRRI dhan 28 29, BRRI dhan 35, BRRI dhan 36, BRRI hybrid dhan 1. Arsenic concentrations were measured in 29 straw, husk and brown and polish rice grain to see the differential accumulation of arsenic among the...

Straighthead Disease of Rice (Oryza sativa L.) Induced by Arsenic

Arsenic accumulation in rice (Oryza sativa L.): human exposure through food chain.

Although human exposure to arsenic is thought to be caused mainly through arsenic-contaminated underground drinking water, the use of this water for irrigation enhances the possibility of arsenic uptake into crop plants. Rice is the staple food grain in Bangladesh. Arsenic content in straw, grain and husk of rice is especially important since paddy fields are extensively irrigated with undergro...
