Abscisic 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 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 کاملIntegration of Cadmium Accumulation, Subcellular Distribution, and Physiological Responses to Understand Cadmium Tolerance in Apple Rootstocks
Cadmium (Cd) is a nonessential and highly toxic element causing agricultural problems. However, little information is available about the variation in Cd tolerance among apple rootstocks and its underlying physiological regulation mechanisms. This study investigated Cd accumulation, subcellular distribution, and chemical forms as well as physiological changes among four apple rootstocks exposed...
متن کاملDefective copper transport in the copt5 mutant affects cadmium tolerance.
Cadmium toxicity interferes with essential metal homeostasis, which is a problem for both plant nutrition and the consumption of healthy food by humans. Copper uptake is performed by the members of the Arabidopsis high affinity copper transporter (COPT) family. One of the members, COPT5, is involved in copper recycling from the vacuole toward the cytosolic compartment. We show herein that copt5...
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 ...
