Gene limiting cadmium accumulation in rice.
Intake of toxic cadmium (Cd) from rice caused Itai-itai disease in the past and it is still a threat for human health. Therefore, control of the accumulation of Cd from soil is an important food-safety issue, but the molecular mechanism for the control is unknown. Herein, we report a gene (OsHMA3) responsible for low Cd accumulation in rice that was isolated from a mapping population derived fr...
متن کاملLow cadmium (LCD), a novel gene related to cadmium tolerance and accumulation in rice
The contamination of food crops by cadmium (Cd) is a major concern in food production because it can reduce crop yields and threaten human health. In this study, knockout rice plants (Oryza sativa) tagged with the gene trap vector pGA2707 were screened for Cd tolerance, and the tolerant line lcd was obtained. The lcd mutant showed tolerance to Cd on agar plates and in hydroponic culture during ...
متن کاملMicroRNA390 Is Involved in Cadmium Tolerance and Accumulation in Rice
Cadmium (Cd) is a non-essential heavy metal that is toxic to plants. microRNAs (miRNAs) are 21-nucleotide RNAs that are ubiquitous regulators of gene expression at the post-transcriptional level. Several plant miRNAs, such as miR390, have vital roles in plant growth, development and responses to environmental stresses including heavy metal stress. In this study, the expression of mature miR390 ...
متن کاملAbscisic acid accumulation and cadmium tolerance in rice seedlings
doi: 10.1111/j.1399-3054.2005.00490.x Rice (Oryza sativa L.) seeds were soaked for 18 h in distilled water in the absence (–PBZ) or presence (þPBZ, a triazole) of 100 mg l 1 paclobutrazol and then air dried. These air-dried seeds were germinated in the dark and then cultivated in a Phytotron. Twelve-day-old –PBZ and þPBZ seedlings were treated or not with CdCl2. Cd toxicity was judged by the de...
متن کاملA Review on the Cadmium Content of Rice, Daily Cadmium Intake, and Accumulation in the Kidneys
A Review on the Cadmium Content of Rice, Daily Cadmium Intake, and Accumulation in the Kidneys: Tomoyuki KAWADA, et al. Department of Public Health, Gunma University School of Medicine—The body burden of cadmium primarily depends on the daily intake of the element in food, and thus the geographical differences in cadmium content in foods and the daily intake of cadmium should be studied. There ...
